RH.11-12.8: Evaluating an Author's Premises, Claims and Evidence Against Other Sources

In plain English: RH.11-12.8 is the Common Core literacy standard for history that asks students in grades 11-12 to evaluate an author's premises, claims and evidence by corroborating or challenging them with other information. The key idea is that a source is tested against other sources, which must be weighed in turn. It is usually taught in U.S. History or Government.

Evaluate an author's premises, claims, and evidence by corroborating or challenging them with other information.

60-75 min

Overview

Students evaluate an author's premises, claims and evidence by corroborating or challenging them with other information. A premise is a statement an argument builds on, often a statement of fact or a value the author treats as settled; a claim is a conclusion the author wants accepted; evidence is what the author offers to back either one. To corroborate is to confirm a statement with a second, independent source; to challenge is to show information that contradicts it or limits it. Students also learn that a source can be silent on a point, which neither confirms nor refutes it, and that agreement counts for less when the second source depends on the first.

The author is President William McKinley. His war message of April 11, 1898 asked Congress to authorize force to end the war in Cuba; it rests on premises about the reconcentration camps, the destruction of the battleship Maine in Havana harbor, and Spain's answers to American proposals. Students test those premises against McKinley's own message of March 28, which summarized the naval court of inquiry, and against Willis Fletcher Johnson's History of Cuba (1920), a later account that reports the Spanish inquiry, the reports of the American consul-general and the last negotiations. Johnson is himself a source to be weighed: he favored the intervention and wrote twenty-two years later.

Learning Objectives

By the end of this lesson, students will be able to:

  • Identify the premises an argument depends on, separating them from its claims and from the evidence offered
  • Corroborate or challenge a premise, claim or piece of evidence with information from another source, citing both texts
  • Weigh the other information itself by its date, closeness to events, independence and the interests of its author
  • Write an evaluation that states which parts of an argument survive the test of other sources and which do not

Prior Knowledge Required

Students should already be comfortable with:

  • Assessing the extent to which the reasoning and evidence in a text support the author's claims RH.9-10.8
  • Citing specific textual evidence from primary and secondary sources RH.11-12.1
  • Basic background: Cubans rose against Spanish rule in 1895; the United States declared war on Spain in April 1898; "reconcentration" was the Spanish policy of moving rural Cubans into towns held by the army

Lesson Procedure

60-75 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Project the prompt and give students three minutes to write.

    Warm-Up Prompt

    "A company announces: 'Our new filter removes 99 percent of lead from tap water, as our engineers' tests confirm.' A city lab tests the filter and reports 90 percent. A customer review says it works perfectly. Which source would you use to check the company's claim, and why is the review weaker than the lab even though it agrees with the company?"

    Take four answers. Draw out the three questions students will use all period: Is the second source independent of the first? How close was it to the facts? What interest did its author have? Then add the fourth: does it address the same point, or is it silent? The lab challenges the exact figure but corroborates that the filter works; the review agrees but tests nothing.

  2. Direct Instruction20 minutes

    Part 1: The test. Show the table. Students keep it beside them as a checklist for every comparison.

    Corroborating or challenging one statement
    StepQuestionPossible results
    1. ClassifyIs the statement a premise, a claim or a piece of evidence?Premise (built on), claim (concluded), evidence (offered as proof)
    2. Find other informationWhich other source speaks to exactly this point?Corroborates, challenges, qualifies, or is silent
    3. Weigh the other sourceHow close to events, how independent, and with what interest?Strong, weak or dependent corroboration or challenge
    4. DecideDoes the premise, claim or evidence still stand?Stands, stands with limits, or falls

    Part 2: The camps. Read T1, McKinley's account of reconcentration, and underline each number and its source. Then read T2, from Johnson's 1920 history, and mark every place where it speaks to the same point. Diagram 1 shows the dates of the texts; Diagram 2 records the results of the examples.

    The efforts of Spain were increased, both by the dispatch of fresh levies to Cuba and by the addition to the horrors of the strife of a new and inhuman phase happily unprecedented in the modern history of civilized Christian peoples. The policy of devastation and concentration, inaugurated by the Captain-General's bando of October 21, 1896, in the Province of Pinar del Rio was thence extended to embrace all of the island to which the power of the Spanish arms was able to reach by occupation or by military operations. The peasantry, including all dwelling in the open agricultural interior, were driven into the garrison towns or isolated places held by the troops.

    The raising and movement of provisions of all kinds were interdicted. The fields were laid waste, dwellings unroofed and fired, mills destroyed, and, in short, everything that could desolate the land and render it unfit for human habitation or support was commanded by one or the other of the contending parties and executed by all the powers at their disposal.

    By the time the present Administration took office, a year ago, reconcentration (so called) had been made effective over the better part of the four central and western provinces--Santa Clara, Matanzas, Havana, and Pinar del Rio.

    The agricultural population to the estimated number of 300,000 or more was herded within the towns and their immediate vicinage, deprived of the means of support, rendered destitute of shelter, left poorly clad, and exposed to the most unsanitary conditions. As the scarcity of food increased with the devastation of the depopulated areas of production, destitution and want became misery and starvation. Month by month the death rate increased in an alarming ratio. By March, 1897, according to conservative estimates from official Spanish sources, the mortality among the reconcentrados from starvation and the diseases thereto incident exceeded 50 per cent of their total number.

    No practical relief was accorded to the destitute. The overburdened towns, already suffering from the general dearth, could give no aid. So-called "zones of cultivation" established within the immediate areas of effective military control about the cities and fortified camps proved illusory as a remedy for the suffering. The unfortunates, being for the most part women and children, with aged and helpless men, enfeebled by disease and hunger, could not have tilled the soil without tools, seed, or shelter for their own support or for the supply of the cities. Reconcentration, adopted avowedly as a war measure in order to cut off the resources of the insurgents, worked its predestined result. As I said in my message of last December, it was not civilized warfare; it was extermination. The only peace it could beget was that of the wilderness and the grave.

    This demand was made not merely by the "yellow press," which was inspired by sordid and sinister motives, but also by the most thoughtful, disinterested and upright men of America. Fitzhugh Lee, the highly competent and trustworthy consul-general at Havana, officially reported in December, 1897, that in the Province of Havana alone there had been 101,000 of the "reconcentrados," of which more than half had died. About 400,000 innocent and unoffending persons, chiefly women and children, had been transformed into imprisoned paupers, to be sustained by charity or to die of disease and famine. Senator Proctor, of Vermont, one of the foremost members of the United States Senate, made a personal tour of investigation in such parts of the island as were accessible, and reported to his colleagues that "It is not peace, nor is it war; it is desolation and distress, misery and starvation." The people of the United States thus came to the conclusion that the Spanish were unable to subdue the Cubans, and that the Cubans were unable to expel the Spanish, and that the war was therefore nothing but a campaign of destruction and extermination, which would end only when one side was exhausted or extirpated. It was impossible that a civilized and humane nation should regard such a spectacle at its very doors with indifference. [...]

    [...]

    Blanco arrived at Havana on November 1, 1897, with the purpose, as he had announced before sailing, of putting sincerely into effect the reforms which Sagasta had outlined, reforms which would, he believed, be acceptable to the Cuban people. He found the condition of affairs in the island to be far worse than it had been reported, or than he had expected. The "reconcentrados" had been dying and were still dying by tens of thousands. The soldiers had not been paid for months and in consequence were disaffected and mutinous, and were looting to obtain food which they had no money to buy. Both the Spanish and the Cuban Autonomists were profoundly dissatisfied; while the Revolutionists, though making no progress, were as implacable as ever. He at once ordered the concentration camps to be abolished, saying that he would not make war upon women and children, and he secured a credit of $100,000 from the Spanish government to assist the Cuban peasantry in the rehabilitation of their ruined farms. All American citizens were released from prison, as were also many Cubans who were under sentence of death. Cuban refugees and exiles were invited to return home, and every facility possible was afforded for the resumption of sugar making and agriculture. He then undertook to put into effect a system of home rule which he fondly hoped would satisfy the Autonomists and would bring the masses of the Cuban people over to the side of that party.

    • A number challenged by other information (T1 paragraph 4, T2 paragraph 1)

      McKinley: "The agricultural population to the estimated number of 300,000 or more was herded within the towns." Johnson: "About 400,000 innocent and unoffending persons, chiefly women and children, had been transformed into imprisoned paupers."

      Result: The premise is the scale of the suffering. Johnson's figure is a third larger (400,000 is 300,000 plus 100,000), so it challenges McKinley's number while corroborating his point that the camps held hundreds of thousands. McKinley's "or more" leaves room for the larger figure. Johnson names no source for his 400,000, so the challenge is weaker than it looks: the premise stands, with its exact size uncertain.

    • Corroboration that fits in part (T1 paragraphs 3-4, T2 paragraph 1)

      McKinley: "By March, 1897, according to conservative estimates from official Spanish sources, the mortality among the reconcentrados [...] exceeded 50 per cent of their total number." Johnson: Fitzhugh Lee "officially reported in December, 1897, that in the Province of Havana alone there had been 101,000 of the 'reconcentrados,' of which more than half had died."

      Result: Lee's report corroborates the scale (more than half of 101,000 is more than 50,500 deaths), and it comes from an official on the spot. But it is dated nine months later and covers one province, so it cannot confirm McKinley's date. McKinley's own text raises doubt about that date: the order he names for Pinar del Rio dates from October 21, 1896 (paragraph 1), about five months before March 1897, and "Month by month the death rate increased" suggests the worst came later. Over half dead so soon would need strong evidence, and McKinley cites only unnamed "official Spanish sources." The claim stands for late 1897; for March 1897 it is not corroborated.

  3. Guided Practice15 minutes

    Now the Maine. T3 is McKinley's message of March 28, which summarized the finding of the naval court of inquiry; T4 is what he said about the same finding two weeks later in the war message. Read both. Pairs test the two statements in the examples, then find one more statement in T4 to test against T3.

    At forty minutes past 9 in the evening of the 15th of February the Maine was destroyed by an explosion, by which the entire forward part of the ship was utterly wrecked. In this catastrophe 2 officers and 264 of her crew perished, those who were not killed outright by her explosion being penned between decks by the tangle of wreckage and drowned by the immediate sinking of the hull.

    [...]

    The usual procedure was followed, as in all cases of casualty or disaster to national vessels of any maritime state. A naval court of inquiry was at once organized, composed of officers well qualified by rank and practical experience to discharge the onerous duty imposed upon them. Aided by a strong force of wreckers and divers, the court proceeded to make a thorough investigation on the spot, employing every available means for the impartial and exact determination of the causes of the explosion. Its operations have been conducted with the utmost deliberation and judgment, and, while independently pursued, no attainable source of information was neglected, and the fullest opportunity was allowed for a simultaneous investigation by the Spanish authorities.

    [...]

    There were two distinct explosions, with a brief interval between them. The first lifted the forward part of the ship very perceptibly; the second, which was more open, prolonged, and of greater volume, is attributed by the court to the partial explosion of two or more of the forward magazines.

    The evidence of the divers establishes that the after part of the ship was practically intact and sank in that condition a very few moments after the explosion. The forward part was completely demolished.

    Upon the evidence of a concurrent external cause the finding of the court is as follows:

    At frame 17 the outer shell of the ship, from a point 11-1/2 feet from the middle line of the ship and 6 feet above the keel when in its normal position, has been forced up so as to be now about 4 feet above the surface of the water, therefore about 34 feet above where it would be had the ship sunk uninjured.

    The outside bottom plating is bent into a reversed V shape (*A), the after wing of which, about 15 feet broad and 32 feet in length (from frame 17 to frame 25), is doubled back upon itself against the continuation of the same plating, extending forward.

    At frame 18 the vertical keel is broken in two and the flat keel bent into an angle similar to the angle formed by the outside bottom plates. This break is now about 6 feet below the surface of the water and about 30 feet above its normal position.

    In the opinion of the court this effect could have been produced only by the explosion of a mine situated under the bottom of the ship at about frame 18 and somewhat on the port side of the ship.

    The conclusions of the court are:

    That the loss of the Maine was not in any respect due to fault or negligence on the part of any of the officers or members of her crew;

    That the ship was destroyed by the explosion of a submarine mine, which caused the partial explosion of two or more of her forward magazines; and

    That no evidence has been obtainable fixing the responsibility for the destruction of the Maine upon any person or persons.

    William McKinley, Messages and Papers of the Presidents: William McKinley, special message of March 28, 1898 (the Maine and the naval court of inquiry; cuts marked [...]) (1898; this edition 1902). Public domain (published 1902). Source text.

    These elements of danger and disorder already pointed out have been strikingly illustrated by a tragic event which has deeply and justly moved the American people. I have already transmitted to Congress the report of the naval court of inquiry on the destruction of the battle ship Maine in the harbor of Havana during the night of the 15th of February. The destruction of that noble vessel has filled the national heart with inexpressible horror. Two hundred and fifty-eight brave sailors and marines and two officers of our Navy, reposing in the fancied security of a friendly harbor, have been hurled to death, grief and want brought to their homes and sorrow to the nation.

    The naval court of inquiry, which, it is needless to say, commands the unqualified confidence of the Government, was unanimous in its conclusion that the destruction of the Maine was caused by an exterior explosion--that of a submarine mine. It did not assume to place the responsibility. That remains to be fixed.

    In any event, the destruction of the Maine, by whatever exterior cause, is a patent and impressive proof of a state of things in Cuba that is intolerable. That condition is thus shown to be such that the Spanish Government can not assure safety and security to a vessel of the American Navy in the harbor of Havana on a mission of peace, and rightfully there.

    Further referring in this connection to recent diplomatic correspondence, a dispatch from our minister to Spain of the 26th ultimo contained the statement that the Spanish minister for foreign affairs assured him positively that Spain will do all that the highest honor and justice require in the matter of the Maine. The reply above referred to, of the 31st ultimo, also contained an expression of the readiness of Spain to submit to an arbitration all the differences which can arise in this matter, which is subsequently explained by the note of the Spanish minister at Washington of the 10th instant, as follows:

    As to the question of fact which springs from the diversity of views between the reports of the American and Spanish boards, Spain proposes that the facts be ascertained by an impartial investigation by experts, whose decision Spain accepts in advance.

    To this I have made no reply.

    • A claim corroborated by the evidence behind it (T4 paragraph 2, T3 paragraphs 6-9)

      T4: the court concluded "that the destruction of the Maine was caused by an exterior explosion--that of a submarine mine." T3 gives the court's evidence: at frame 17 the outer shell was "forced up" about 34 feet above where it would lie, the keel at frame 18 was "broken in two," and "this effect could have been produced only by the explosion of a mine."

      Result: T3 corroborates that the court said this, and it shows physical evidence gathered by divers, which is strong evidence for its time. It is not independent corroboration of the cause: both texts report the same court. The word "only" is the court's inference from bent plates, not an observation, so a second investigation could test it.

    • A premise built to stand without a finding of guilt (T4 paragraph 3, T3 paragraph 13)

      T4: "the destruction of the Maine, by whatever exterior cause, is a patent and impressive proof of a state of things in Cuba that is intolerable," because "the Spanish Government can not assure safety and security" to an American ship. T3: "no evidence has been obtainable fixing the responsibility for the destruction of the Maine upon any person or persons."

      Result: T3 explains why McKinley wrote "by whatever exterior cause": the court could not say who set off the mine, so his premise does not depend on Spanish guilt. The court's finding therefore qualifies the premise rather than proving it. It stands only if an outside explosion in a Spanish-held harbor is itself proof that Spain could not keep order, an assumption that no finding in T3 tests.

  4. Independent Practice15-20 minutes

    Students read T5, Johnson's account of the explosion and the two inquiries, and T6, McKinley's four grounds for intervention. For each of the four grounds, they write the premise it rests on and look for other information on the page that corroborates or challenges it. Then they take the quiz, which uses T5 and T6 with T1-T4.

    There next occurred the greatest and most mysterious tragedy of the entire revolutionary period. On the evening of February 15, at twenty minutes before ten o'clock, a violent explosion occurred under or in the forward portion of the Maine as she lay in Havana harbor, sufficient to lift the hull some distance above its normal level. A few seconds later another and more violent explosion followed, which so completely destroyed the forward part of the ship that most of it could never be found. The remainder of the vessel almost immediately sank, in about six fathoms of water. Of the complement of 360, two officers and 264 men were killed, and of the remainder 60 were wounded. Captain Sigsbee, commander of the Maine, telegraphed to Washington that all judgment upon the matter should be suspended until after full investigation. Blanco telegraphed to Madrid that the catastrophe was doubtless due to an accident within the ship, and the Madrid government promptly expressed regret and sympathy.

    In the United States there was a great outburst of grief and rage. Even the most restrained and conservative could not help a degree of suspicion of foul play, though of course not on the part of the Spanish government. A semi-criminal faction, in the "yellow" press, clamored furiously for war, charging Spaniards, even the Spanish government, with direct and malicious responsibility for the tragedy, and even publishing the grossest of falsehoods for the sake of inflaming popular sentiment. Too large a proportion of the nation was swayed by these latter sordid and sinister influences. But at least the government kept its head, and acted with admirable discretion; though for so doing the President incurred the virulent animosity of the chief clamorer for war, an animosity which was persistently maintained until it culminated in the incitement of a criminal Anarchist to assassinate the President.

    [...]

    The Spanish government proposed a joint investigation into the disaster, but the United States government declined and conducted a thorough investigation of its own, through a board of eminent official experts. The report was that the loss of the ship was not due to any accident or to any negligence on the part of the officers and crew. The first explosion was external to the hull, as if caused by a torpedo or mine, and it caused the second explosion, which was that of the ship's magazines. The Spanish government then conducted an investigation of its own, resulting in a report that both explosions were within the ship and were presumably purely accidental. It may be added that a final examination in after years, when a cofferdam was built about the hulk and it was floated and then taken out to sea and sunk in deep water, fully confirmed the report of the American investigating board.

    [...]

    The findings of the American board of investigation were reported officially to the Spanish government, and the President in a message to Congress expressed confidence that Spain would act in the matter according to the dictates of justice, honor and friendship. The Spanish government replied that it would certainly do so, and it presently proposed to submit the whole subject to investigation by impartial experts, and to determination by arbitration. But this proposal was not made until April 10, when so much else had occurred to strain relations between the two countries that it could not be entertained by the United States.

    The forcible intervention of the United States as a neutral to stop the war, according to the large dictates of humanity and following many historical precedents where neighboring states have interfered to check the hopeless sacrifices of life by internecine conflicts beyond their borders, is justifiable on rational grounds. It involves, however, hostile constraint upon both the parties to the contest, as well to enforce a truce as to guide the eventual settlement.

    The grounds for such intervention may be briefly summarized as follows:

    First. In the cause of humanity and to put an end to the barbarities, bloodshed, starvation, and horrible miseries now existing there, and which the parties to the conflict are either unable or unwilling to stop or mitigate. It is no answer to say this is all in another country, belonging to another nation, and is therefore none of our business. It is specially our duty, for it is right at our door.

    Second. We owe it to our citizens in Cuba to afford them that protection and indemnity for life and property which no government there can or will afford, and to that end to terminate the conditions that deprive them of legal protection.

    Third. The right to intervene may be justified by the very serious injury to the commerce, trade, and business of our people and by the wanton destruction of property and devastation of the island.

    Fourth, and which is of the utmost importance. The present condition of affairs in Cuba is a constant menace to our peace and entails upon this Government an enormous expense. With such a conflict waged for years in an island so near us and with which our people have such trade and business relations; when the lives and liberty of our citizens are in constant danger and their property destroyed and themselves ruined; where our trading vessels are liable to seizure and are seized at our very door by war ships of a foreign nation; the expeditions of filibustering that we are powerless to prevent altogether, and the irritating questions and entanglements thus arising--all these and others that I need not mention, with the resulting strained relations, are a constant menace to our peace and compel us to keep on a semi war footing with a nation with which we are at peace.

  5. Closure5-10 minutes

    Exit ticket: On an index card, write one of McKinley's premises that survives the test of other sources and one that is weakened, each with the source that decided it: "The premise that ___ is (corroborated / challenged) by ___, which is (strong / weak) because ___."

    Teacher note on the sources and later findings: The passages are quoted exactly as printed in 1902 and 1920. Johnson writes as a supporter of the intervention; his language about the "yellow" press, about Spanish officers ("some malignant Spanish officer") and about Spain in general is partisan, and students should weigh it as such. His charge that the "chief clamorer for war" (he means the publisher William Randolph Hearst) incited the anarchist who assassinated McKinley in 1901 is his own accusation; no such link was ever proved. Findings from outside the texts help with the Maine. The 1898 court (often called the Sampson board, after its president, Captain William T. Sampson) found an external mine, as T3 reports. When the wreck was exposed and examined in 1911, a second naval board (the Vreeland board) also concluded that an outside explosion set off the magazines, but it placed that explosion farther aft than the 1898 court had and found that the bending at frame 18 was caused by the magazines, so Johnson's "fully confirmed" overstates the agreement. In 1976 a study directed by Admiral Hyman Rickover concluded that the cause was probably internal, a fire in a coal bunker next to a magazine, which was close to the Spanish finding; a 1998 computer study for National Geographic was inconclusive, and the cause is still debated. Counts of the dead differ from source to source (modern references give figures from 260 to 268), partly because some men died of their injuries after the explosion. Modern estimates of the number of Cubans who died under reconcentration also vary widely, from under 200,000 to as many as 400,000 in different accounts, and the policy's deaths are hard to separate from those of the war as a whole. Use these facts after students have worked from the 1898 and 1920 texts, as a lesson in how new information can challenge a premise that once looked settled.

    Homework passages. The relief and armistice paragraphs and the close of the war message (T7) and Johnson's account of the Williams warning and the last negotiations (T8), used for the homework problems.

    Thousands of lives have already been saved. The necessity for a change in the condition of the reconcentrados is recognized by the Spanish Government. Within a few days past the orders of General Weyler have been revoked. The reconcentrados, it is said, are to be permitted to return to their homes and aided to resume the self-supporting pursuits of peace. Public works have been ordered to give them employment and a sum of $600,000 has been appropriated for their relief.

    [...]

    Realizing this, it appeared to be my duty, in a spirit of true friendliness, no less to Spain than to the Cubans, who have so much to lose by the prolongation of the struggle, to seek to bring about an immediate termination of the war. To this end I submitted on the 27th ultimo, as a result of much representation and correspondence, through the United States minister at Madrid, propositions to the Spanish Government looking to an armistice until October 1 for the negotiation of peace with the good offices of the President.

    In addition I asked the immediate revocation of the order of reconcentration, so as to permit the people to return to their farms and the needy to be relieved with provisions and supplies from the United States, cooperating with the Spanish authorities, so as to afford full relief.

    The reply of the Spanish cabinet was received on the night of the 31st ultimo. It offered, as the means to bring about peace in Cuba, to confide the preparation thereof to the insular parliament, inasmuch as the concurrence of that body would be necessary to reach a final result, it being, however, understood that the powers reserved by the constitution to the central Government are not lessened or diminished. As the Cuban parliament does not meet until the 4th of May next, the Spanish Government would not object for its part to accept at once a suspension of hostilities if asked for by the insurgents from the general in chief, to whom it would pertain in such case to determine the duration and conditions of the armistice.

    [...]

    The issue is now with the Congress. It is a solemn responsibility. I have exhausted every effort to relieve the intolerable condition of affairs which is at our doors. Prepared to execute every obligation imposed upon me by the Constitution and the law, I await your action.

    Yesterday, and since the preparation of the foregoing message, official information was received by me that the latest decree of the Queen Regent of Spain directs General Blanco, in order to prepare and facilitate peace, to proclaim a suspension of hostilities, the duration and details of which have not yet been communicated to me.

    This fact, with every other pertinent consideration, will, I am sure, have your just and careful attention in the solemn deliberations upon which you are about to enter. If this measure attains a successful result, then our aspirations as a Christian, peace-loving people will be realized. If it fails, it will be only another justification for our contemplated action.

    It is to be recalled that Ramon O. Williams, who had only a little while before retired from the office of American Consul-General at Havana, and was particularly well informed and judicious, earnestly warned the United States government against sending a ship to Havana, because the harbor was very elaborately mined, and there was a bitter and truculent feeling among the Spaniards against the United States; wherefore the danger of some untoward occurrence was too great to be incurred without a more pressing necessity than was then apparent. But despite his warning the Maine was sent. She was conducted by a Spanish official pilot to her anchorage at a buoy between Regla and the old custom house. Whether a mine was attached to that buoy or not is unknown, though Mr. Williams was confident that one was. His theory was that some malignant Spanish officer, who had access to the keyboard of the mines, perhaps through connivance with some other fanatic, watched to see the tide swing the ship directly over the mine and then touched the key and caused the explosion. That would account for the enormous hole which was blown in the side of the ship, and which could not have been caused by any little mine or torpedo which might have been floated to the side of the ship, but must have been produced by a very large mine planted deep beneath the hull.

    [...]

    There could be no greater mistake than that which has been too often and too persistently made, in regarding the destruction of the Maine as the cause of American, intervention in Cuba. The declarations of policy which we have already quoted from the messages of President Cleveland and President McKinley, the former fourteen months and the latter two months before that vessel went to Havana, are ample indications of the purpose of the American government to intervene unless there were a satisfactory amelioration of Cuban affairs. But there was no such amelioration, and therefore war was declared. It unquestionably would have been declared just the same, perhaps at a later and perhaps at an earlier date, if there had been no Maine at all.

    Beginning before the destruction of the Maine, and accelerated after that event, both sides were preparing for war. Nevertheless diplomatic negotiations continued, chiefly conducted by the American Minister, Stewart L. Woodford, at Madrid. In order to facilitate such negotiations, President McKinley withheld the report on the Maine from Congress for a time. Spain asked that the pacification of Cuba, which the United States was urging, be left to the Autonomist Legislature, which was to meet on May 4. The United States, declaring that it did not want Cuba but did want peace in Cuba, proposed an armistice to begin at once and to last until October 1, itself meantime to act as mediator between the Cubans and Spain. Spain replied that an armistice would be granted, to last at the pleasure of the Spanish commander, if the Cubans would ask for it themselves; and that already General Blanco had abandoned the "concentration" system. This was of course regarded as entirely unsatisfactory to the United States, but the peace-loving President McKinley hesitated to report to Congress his dissatisfaction with it.

Differentiation Strategies

For Struggling Students

  • Give a two-column organizer with McKinley's statement already copied on the left, so students only find and weigh the other information
  • Pre-teach six terms in one sentence each: reconcentration, court of inquiry, frame (of a ship), armistice, arbitration, filibustering (private armed expeditions to help a rebellion)
  • Work only with numbers first (T1 against T2), where agreement and disagreement are easiest to see, before moving to claims about responsibility

For Advanced Students

  • Read Senator Redfield Proctor's speech of March 17, 1898 in the Congressional Record and decide which of McKinley's premises in T1 it corroborates and which it does not address
  • Read a summary of the 1911 board's report on the raised wreck and of Admiral Rickover's 1976 study, and rewrite the evaluation of T4 in light of each
  • Compare McKinley's grounds in T6 with the joint resolution on Cuba that McKinley signed on April 20, 1898, and explain which premises Congress kept and which it added

Assessment Guidance

What to Look For

Strong work names the kind of statement being tested (premise, claim or evidence), quotes the other information exactly, says whether it corroborates, challenges, qualifies or is silent, and weighs that information by date, closeness, independence and interest before reaching a verdict. Watch for students who treat any agreement as proof, who count a source that repeats the first as independent confirmation, or who treat later knowledge as if McKinley had it in April 1898. A strong evaluation often ends with a divided verdict: a premise stands on one point and falls on another.

Classroom Activities

3 Activities

1

Corroboration Grid

20 minGroups of 3

Each group tests six statements from McKinley's messages against the other texts on the page. For each, the group writes the other information, marks it C (corroborates), X (challenges), Q (qualifies) or S (no other source speaks to it), and rates the other source strong or weak.

The Six Statements

  1. Reconcentration "had been made effective over the better part of the four central and western provinces" (T1 paragraph 3)
  2. "No practical relief was accorded to the destitute" (T1 paragraph 5)
  3. The policy was "inaugurated by the Captain-General's bando of October 21, 1896, in the Province of Pinar del Rio" (T1 paragraph 1)
  4. "There were two distinct explosions, with a brief interval between them" (T3 paragraph 3)
  5. The court was "composed of officers well qualified by rank and practical experience" (T3 paragraph 2)
  6. Spain's foreign minister promised that "Spain will do all that the highest honor and justice require in the matter of the Maine" (T4 paragraph 4)

Teacher Key

  • 1: C, for Havana province only: Lee's report of 101,000 reconcentrados there (T2 paragraph 1); the other provinces are not tested
  • 2: X, weak: Johnson says the reconcentrados were "sustained by charity or to die" (T2 paragraph 1), which admits some relief, but he names no source for it
  • 3: S: no other text on the page gives a date for the order; students should say what source would test it (the order itself, or a Spanish record)
  • 4: C, but dependent: Johnson's "A few seconds later another and more violent explosion followed" (T5 paragraph 1) matches the court, and he probably drew on the same report, so it is not independent
  • 5: S: nothing on the page tests the officers' qualifications, and McKinley is describing his own government's court
  • 6: C: Johnson reports that "The Spanish government replied that it would certainly do so" (T5 paragraph 4), a later account of the same exchange

Discussion Questions

  • Which "C" in your grid is weakest, and why does agreement not always mean confirmation?
  • Statement 3 has no other source on the page. Is an untested statement weaker than a challenged one?
  • Johnson wrote in 1920 with McKinley's messages in front of him. How does that change what his agreement is worth?

Variation for a Shorter Class

Test statements 1, 3 and 4 only: one corroborated, one untested and one corroborated by a dependent source.

2

Weigh the Witness

15 minPairs

Pairs rate four sources of "other information" on three scales, closeness to events, independence from McKinley and interest in the outcome, and then decide which source they would trust most on which question.

The Four Sources

  1. Consul-General Fitzhugh Lee's report of December 1897, as Johnson summarizes it (T2 paragraph 1)
  2. The naval court of inquiry's measurements of the wreck (T3 paragraphs 6-8)
  3. Johnson's own narrative, written in 1920 (T2 and T5)
  4. The Spanish minister's note of April 10, 1898, quoted by McKinley (T4 paragraph 5)

Teacher Key

  • Lee: close (on the spot), official, independent of McKinley's message, though an American official rather than a neutral observer; strongest on conditions in Havana province
  • The court: close and physical, but its officers judged the loss of their own Navy's ship, and one of its conclusions clears the ship's officers of "fault or negligence" (T3 paragraph 11); strongest on what the wreck looked like, weaker on what caused it
  • Johnson: distant in time and dependent on earlier reports; useful for dates and details McKinley left out, and weakest where he only repeats McKinley
  • The Spanish note: an interested party, but the offer itself is a fact, so it is strong evidence of what Spain proposed and weak evidence of what happened to the ship

Discussion Questions

  • Can a source with an interest in the outcome still be the best evidence on some question? Give an example from the four.
  • Which of the four would you most want to read in full, and what would you look for?

Modification for English Learners

Give the three scales as pictures (a clock for closeness, two separate circles for independence, a scale for interest) and let pairs place a card for each source.

Senate Committee, April 1898 and Again in 1920

15 minGroups of 4

After the quiz, each group sits as a Senate committee on April 12, 1898 and votes on whether McKinley's premises are sound, using only what was available then: T1, T3, T4, T6 and T7. Then the group reconvenes "in 1920" with Johnson's T2, T5 and T8 and votes again. The group reports which premise changed most between the two votes.

Procedure

  • List McKinley's premises on the camps, the Maine and Spain's answers; one member keeps the list
  • First vote (April 1898): for each premise, sound, doubtful or unsound, with one quotation
  • Second vote (1920): repeat with T2, T5 and T8 added; note every changed vote
  • Report in one minute: the premise that changed most and the information that changed it

Teacher Key

  • Votes will differ. A strong report names specific information, for example Lee's figures (T2) for the camps, and weighs it by interest and independence
  • Watch for groups that use hindsight in the first vote; the point of the two votes is to separate what McKinley could know from what later sources add

Discussion Questions

  • Is it fair to judge a premise by information the author could not have had?
  • Which premise survived both votes, and what made it hard to challenge?

Homework Assignment

~30 min

RH.11-12.8 Homework: The Last Negotiations

Directions: Use T7, from the close of McKinley's war message, and T8, from Johnson's history, both printed in the Closure phase of the lesson plan. Use the other texts and Diagram 1 where a problem names them. Quote the words you use and give the text and paragraph number. Answer Problems 1-5 in 4-6 sentences each; Problem 6 is a short essay.

Part 1: Relief and the Armistice (Problems 1-3)

  1. McKinley reports that "Within a few days past the orders of General Weyler have been revoked" (T7 paragraph 1). Johnson says that Blanco, who arrived in November 1897, "at once ordered the concentration camps to be abolished" (T2 paragraph 2). Do the two sources corroborate or challenge each other? Which statement is better supported on this page, and what other information would settle the question?
  2. McKinley writes, "I have exhausted every effort to relieve the intolerable condition of affairs which is at our doors" (T7 paragraph 5). Corroborate or challenge this claim with at least two pieces of information from T7 paragraphs 4-7 and T4 paragraphs 4-6.
  3. Johnson describes Spain's reply to the armistice proposal (T8 paragraph 3), and McKinley describes the same reply (T7 paragraph 4). Compare the two accounts: where do they agree, what does Johnson add, and does anything he adds change your evaluation of McKinley's account?

Part 2: Johnson Tested (Problems 4-6)

  1. Evaluate Ramon O. Williams's theory of the explosion as Johnson reports it (T8 paragraph 1). What kind of evidence supports it, what does Johnson himself concede about it, and how do the court's findings (T3 paragraphs 6-13) and the Spanish inquiry (T5 paragraph 3) bear on it?
  2. Johnson says that "President McKinley withheld the report on the Maine from Congress for a time" (T8 paragraph 3). Test this claim against the dates in Diagram 1 and in T3. How long was "a time," and does the evidence support Johnson's explanation of why?
  3. Write a short essay of 250-300 words evaluating Johnson's claim that war "unquestionably would have been declared just the same [...] if there had been no Maine at all" (T8 paragraph 2). Corroborate or challenge the claim with at least three texts on this page, including McKinley's own words in T4 and T6, and explain which evidence is strongest.

  1. Question 1 of 20 · Multiple Choice

    Johnson reports that the Spanish investigation found "both explosions were within the ship and were presumably purely accidental" (T5 paragraph 3). How does this information bear on McKinley's claim in T4 that the Maine was destroyed by an "exterior explosion"?

  2. Question 2 of 20 · Multiple Choice

    Johnson summarizes the American board's report: "The first explosion was external to the hull, as if caused by a torpedo or mine" (T5 paragraph 3). Compared with the court's words in T3 paragraph 9, what does his summary do?

  3. Question 3 of 20 · Multiple Choice

    T3, T4 and T5 each give the number of the Maine's dead. Which statement about them is accurate?

  4. Question 4 of 20 · Multiple Choice

    Johnson writes that "Blanco telegraphed to Madrid that the catastrophe was doubtless due to an accident within the ship" (T5 paragraph 1). How much weight does this telegram carry as a challenge to the naval court's finding?

  5. Question 5 of 20 · Multiple Choice

    Johnson says that Spain's proposal to submit the question to impartial experts and arbitration "was not made until April 10" (T5 paragraph 4). What does T4 show about this claim?

    Johnson writes that Blanco "found the condition of affairs in the island to be far worse than it had been reported, or than he had expected" (T2 paragraph 2). As other information for testing T1, what does this statement do?

  7. Question 7 of 20 · Multiple Choice

    McKinley's first ground rests on the premise that the parties are "either unable or unwilling to stop or mitigate" the suffering (T6 paragraph 3). Which information on the page most directly challenges that premise?

  8. Question 8 of 20 · Multiple Choice

    McKinley's second ground says that American citizens in Cuba need protection "which no government there can or will afford" (T6 paragraph 4). Which information in T2 bears most directly on this premise?

  9. Question 9 of 20 · Multiple Choice

    McKinley says intervention would follow "many historical precedents where neighboring states have interfered" (T6 paragraph 1). What information would best corroborate this premise?

  10. Question 10 of 20 · Multiple Choice

    Among the menaces to American peace, McKinley lists "the expeditions of filibustering that we are powerless to prevent altogether" (T6 paragraph 6). Filibustering expeditions were private armed expeditions from the United States to help the Cuban rebels. How does this detail affect his premise that Cuba's condition is a menace to American peace?

  11. Question 11 of 20 · Multiple Choice

    McKinley says the court "was unanimous in its conclusion" (T4 paragraph 2). What does the summary of the court's findings in T3 show about this detail?

  12. Question 12 of 20 · Multiple Choice

    Johnson says the United States "declined" Spain's proposal of a joint investigation (T5 paragraph 3). McKinley says the court's work was "independently pursued" while "the fullest opportunity was allowed for a simultaneous investigation by the Spanish authorities" (T3 paragraph 2).

  17. Question 17 of 20 · Short Answer

    McKinley writes that the devastation "was commanded by one or the other of the contending parties" (T1 paragraph 2) and that intervention would involve "hostile constraint upon both the parties" (T6 paragraph 1). Evaluate whether this premise fits his case for intervention, using Johnson's description of the war in T2.

  18. Question 18 of 20 · Short Answer

    Identify two features of Johnson's writing in T2 and T5 that affect how much his corroboration of McKinley should count, and judge how much it counts overall.

  19. Question 19 of 20 · Short Answer

    After quoting Spain's proposal that "the facts be ascertained by an impartial investigation by experts, whose decision Spain accepts in advance," McKinley writes, "To this I have made no reply" (T4 paragraphs 5-6). How does this choice bear on his premise that the Maine proves "a state of things in Cuba that is intolerable"? Use Johnson's explanation in T5 paragraph 4.

Frequently Asked Questions

10 Questions

What does RH.11-12.8 mean?

RH.11-12.8 asks students in grades 11-12 to evaluate an author's premises, claims and evidence by corroborating or challenging them with other information. "RH" stands for Reading in History/Social Studies, "11-12" is the grade band and "8" is the eighth reading standard. Students do not judge the text only on its own terms; they test it against other sources.

What is a premise, and how is it different from a claim?

A premise is a statement an argument builds on, often a fact or a value the author treats as settled; a claim is the conclusion the author draws. In McKinley's war message, the scale of death in the reconcentration camps is a premise, and "the war in Cuba must stop" is a claim built on it. Premises matter because a claim can be no stronger than the premises under it.

What does it mean to corroborate a source?

To corroborate is to confirm a statement with a second source that speaks to the same point and does not simply repeat the first. A later history that copies an official report agrees with it but does not corroborate it independently. Students ask of every second source how close it was to events, how independent it is and what interest its author had.

How is RH.11-12.8 different from RH.9-10.8?

RH.9-10.8 asks students to assess how far the reasoning and evidence inside one text support its claims. RH.11-12.8 adds premises to the list of things to test and requires other information: students corroborate or challenge the author with other sources, and they weigh those sources too.

How is RH.11-12.8 different from RH.11-12.6?

RH.11-12.6 compares authors' differing points of view on the same event by assessing each author's claims, reasoning and evidence. RH.11-12.8 keeps one author at the center and uses other sources as tests of that author's premises, claims and evidence. The same documents can serve both standards, but the question differs: "whose view is better supported?" against "does this author survive the check?"

Why use McKinley's 1898 war message to teach RH.11-12.8?

Because the message rests on premises that other sources speak to directly: numbers from the reconcentration camps, the finding of the naval court on the Maine, and Spain's answers to American proposals. McKinley's own earlier message, a Spanish inquiry reported by a later historian and the dates of the diplomatic notes let students corroborate some premises, challenge others and find some that no source on the page tests.

Should students use what historians know today to judge a source from 1898?

Yes, but separately. RH.11-12.8 invites any other information, including later findings. Students should first judge the argument with what was available at the time and then say what later information adds, so they do not blame an author for not knowing what was found later. The lesson's Activity 3 is built on that two-step judgment.

What mistakes do students make with RH.11-12.8?

A common one is treating any agreement as proof, even when the second source depends on the first. Another is treating a source's silence as a challenge. Students also forget to weigh the second source: a later, partisan history can be useful for the details it adds and weak where it only echoes the author. Asking "independent, close, interested?" of every source fixes most of these.

How is RH.11-12.8 assessed?

Usually with a primary source and one or more other sources, and questions that ask which information corroborates or challenges a statement, how a second source should be weighed, or which premise an argument depends on. Written tasks ask for an evaluation that tests an author against other documents with quotations. The lesson's quiz and homework use both forms.

Which class teaches RH.11-12.8?

RH.11-12.8 is a literacy standard for history and social studies, so it is usually taught in grade 11 or 12 U.S. History or Government, alongside the content of the course. It builds on RH.9-10.8 and pairs well with research writing, where students must corroborate the sources they cite.
