RH.6-8.9: How a Secondary Source Uses a Primary Source: Caesar and Dickens on the Invasion of Britain

In plain English: RH.6-8.9 is the Common Core literacy standard for history/social studies in grades 6-8 that asks students to analyze the relationship between a primary and secondary source on the same topic. Students trace what a later history borrows from an eyewitness account, what it adds, leaves out or changes, and why the two accounts differ.

Analyze the relationship between a primary and secondary source on the same topic.

Lesson Plan

60-75 min

Overview

Students learn to analyze the relationship between a primary and a secondary source on the same topic. A primary source was made by someone who took part in or saw the events, at or near the time. A secondary source was made later, by someone who was not there, from other sources. The primary sources are chapters from Julius Caesar's own account of his invasions of Britain in 55 and 54 BC. The secondary source is Charles Dickens's A Child's History of England, which first appeared in 1851 and tells the same story for young readers, relying heavily on Caesar.

Students ask five relationship questions of each pair of passages (Diagram 1): what the secondary source borrows, what it adds, what it leaves out, what it changes, and why. The teacher models the questions on the landing, pairs apply them to a storm that wrecked Caesar's fleet, and students apply them alone to the British war-chariots and, for homework, to the second invasion. Diagram 2 shows, to scale, the 1,905 years between the events and Dickens's history.

Learning Objectives

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

  • Explain why a text is a primary or a secondary source on a given topic
  • Identify what a secondary source borrows from a primary source, by quotation or paraphrase
  • Identify what a secondary source adds, leaves out or changes compared with its primary source
  • Explain how a later writer's time, purpose and readers shape the relationship between the two sources

Prior Knowledge Required

Students should already be comfortable with:

  • Analyzing multiple accounts of the same event and noting differences in point of view RI.5.6
  • Citing specific textual evidence from primary and secondary sources RH.6-8.1
  • Basic background: ancient Rome was ruled from the city of Rome in Italy, and its armies were organized in legions

Lesson Procedure

60-75 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Start with a situation every student knows: a class trip.

    Warm-Up Prompt

    "Maya went on the class trip to the science museum and wrote about it in her journal that night. A month later, Leo, who stayed home sick, wrote a short article about the trip for the school newsletter. Name one thing Leo might copy from Maya's journal, one thing he might add, and one thing he might leave out. Why might his article sound different from her journal?"

    Take answers and sort them on the board under four headings: borrows, adds, leaves out and changes. Then name the two kinds of source. Maya's journal is a primary source: it was made by someone who took part in the events, at or near the time. Leo's article is a secondary source: it was made later by someone who was not there, using other sources. RH.6-8.9 asks students to analyze the relationship between the two: to work out what the later source does with the earlier one and why. Today's sources are Julius Caesar's own account of invading Britain in 55 and 54 BC and the story Charles Dickens told about it for young readers in 1851.

  2. Direct Instruction20 minutes

    Part 1: The two sources. Julius Caesar was the Roman general who conquered Gaul (present-day France, Belgium and nearby lands) between 58 and 50 BC. In 55 BC and again in 54 BC he crossed the English Channel and landed in Britain. He wrote the story of these wars himself, in Latin, calling himself "Caesar" and his soldiers "our men." A legion was a Roman army unit of several thousand foot soldiers, and its eagle was its sacred metal standard, carried on a pole; losing it was a terrible disgrace. About 1,900 years later, the English novelist Charles Dickens wrote A Child's History of England for young readers. Nobody alive in 1851 had seen the invasions, so Dickens depended on ancient writers, above all on Caesar. Gloss before reading Source 1: "barbarians" (Caesar's word for peoples outside the Roman world; see the teacher note in Closure), "embarrassed" (weighed down), "wont" (used to), "flank" (side of an army), "engines" (machines that hurl stones or darts), "supplicating" (praying to), "commonwealth" (the Roman state).

    XXIV.--But the barbarians, upon perceiving the design of the Romans, sent forward their cavalry and charioteers, a class of warriors of whom it is their practice to make great use in their battles, and following with the rest of their forces, endeavoured to prevent our men landing. In this was the greatest difficulty, for the following reasons, namely, because our ships, on account of their great size, could be stationed only in deep water; and our soldiers, in places unknown to them, with their hands embarrassed, oppressed with a large and heavy weight of armour, had at the same time to leap from the ships, stand amidst the waves, and encounter the enemy; whereas they, either on dry ground, or advancing a little way into the water, free in all their limbs, in places thoroughly known to them, could confidently throw their weapons and spur on their horses, which were accustomed to this kind of service. Dismayed by these circumstances and altogether untrained in this mode of battle, our men did not all exert the same vigour and eagerness which they had been wont to exert in engagements on dry ground.

    XXV.--When Caesar observed this, he ordered the ships of war, the appearance of which was somewhat strange to the barbarians and the motion more ready for service, to be withdrawn a little from the transport vessels, and to be propelled by their oars, and be stationed towards the open flank of the enemy, and the enemy to be beaten off and driven away with slings, arrows, and engines: which plan was of great service to our men; for the barbarians being startled by the form of our ships and the motions of our oars and the nature of our engines, which was strange to them, stopped, and shortly after retreated a little. And while our men were hesitating [whether they should advance to the shore], chiefly on account of the depth of the sea, he who carried the eagle of the tenth legion, after supplicating the gods that the matter might turn out favourably to the legion, exclaimed, "Leap, fellow soldiers, unless you wish to betray your eagle to the enemy. I, for my part, will perform my duty to the commonwealth and my general." When he had said this with a loud voice, he leaped from the ship and proceeded to bear the eagle toward the enemy. Then our men, exhorting one another that so great a disgrace should not be incurred, all leaped from the ship. When those in the nearest vessels saw them, they speedily followed and approached the enemy.

    Such was the improved condition of the ancient Britons, fifty-five years before the birth of Our Saviour, when the Romans, under their great General, Julius Cæsar, were masters of all the rest of the known world. Julius Cæsar had then just conquered Gaul; and hearing, in Gaul, a good deal about the opposite Island with the white cliffs, and about the bravery of the Britons who inhabited it—some of whom had been fetched over to help the Gauls in the war against him—he resolved, as he was so near, to come and conquer Britain next.

    So, Julius Cæsar came sailing over to this Island of ours, with eighty vessels and twelve thousand men. And he came from the French coast between Calais and Boulogne, ‘because thence was the shortest passage into Britain;’ just for the same reason as our steam-boats now take the same track, every day. He expected to conquer Britain easily: but it was not such easy work as he supposed—for the bold Britons fought most bravely; and, what with not having his horse-soldiers with him (for they had been driven back by a storm), and what with having some of his vessels dashed to pieces by a high tide after they were drawn ashore, he ran great risk of being totally defeated. However, for once that the bold Britons beat him, he beat them twice; though not so soundly but that he was very glad to accept their proposals of peace, and go away.

    Part 2: Five relationship questions. Show Diagram 1. To analyze how a secondary source relates to a primary source, ask: (1) What does it borrow, by quoting or restating? (2) What does it add that the primary source does not say? (3) What does it leave out? (4) What does it change, by rewording, combining or shifting the emphasis? (5) Why? What about the later writer's time, purpose, readers or other sources explains the differences? Model each question aloud with Sources 1 and 2.

    • Which source is which? (Sources 1 and 2)

      Why is Source 1 the primary source and Source 2 the secondary source, even though both are old books?

      Result: Caesar commanded the landing and wrote about it within a few years, so his account comes from a participant. Dickens was born about 1,900 years later and could know the events only through earlier writers. Age alone does not decide it: what matters is how close the writer was to the events. Diagram 2 shows the distance, drawn to scale.

    • Borrows: a quotation inside the secondary source (Source 2)

      Dickens writes that Caesar sailed from the French coast "because thence was the shortest passage into Britain." What do his quotation marks tell a reader?

      Result: They show that Dickens is repeating another writer's words, here an English version of Caesar's own reason for sailing from that coast. A secondary source that quotes its primary source shows the link openly. The words match Caesar's Latin in chapter XXI, before Source 1, where he goes to the coast of the Morini "because thence was the shortest passage." Dickens does not say which English version he used. The 1915 translation used on this page leaves that reason out of chapter XXI; it gives a similar reason only in Book V, for the port used on the second invasion. Translations of the same Latin can differ, which is one more reason to compare sources carefully.

    • Changes: why was the landing hard? (Sources 1 and 2)

      Caesar explains why his men struggled. How does Dickens explain the same struggle?

      Result: Caesar gives practical reasons: the big ships "could be stationed only in deep water," and the soldiers were "oppressed with a large and heavy weight of armour" while the Britons fought "in places thoroughly known to them." Dickens sums up the fight as "the bold Britons fought most bravely." He keeps the idea that the Romans had a hard time but changes the cause: from deep water and heavy armor to British courage.

    • Leaves out: the eagle-bearer (Sources 1 and 2)

      Caesar tells how the eagle-bearer of the tenth legion leaped into the sea and shouted, "Leap, fellow soldiers, unless you wish to betray your eagle to the enemy." Where is this scene in Source 2?

      Result: It is not there. Dickens leaves out the most famous moment of Caesar's account, a Roman act of courage. One likely reason is his purpose: he is telling the history of England to British children, and his story of the invasion centers on the Britons. Noticing what a secondary source leaves out tells a reader about its point of view.

    • Adds, and why: a claim that is Dickens's own (Source 2)

      Dickens says Caesar "expected to conquer Britain easily." Does Caesar's account say this?

      Result: No. It is Dickens's addition. In fact, in chapter XX, just before Source 1, Caesar says that even if the season was too short for a war, "he thought it would be of great service to him if he only entered the island" and learned about its people and harbors. Dickens's claim makes a better story, with a proud general humbled, but a reader who checks the primary source finds a more careful plan.

    Close the modeling with the point of the standard: the relationship runs both ways. A secondary source depends on its primary sources, so it can repeat their errors and their point of view. It can also explain, question or reframe them. Neither source alone gives the whole picture.

  3. Guided Practice15 minutes

    Source 3 tells what happened four days after the landing. The cavalry (soldiers on horseback) had been waiting across the Channel in eighteen ships of their own. Gloss: "gale" (here, a steady wind), "strand" (beach), "ships of burden" (transport ships), "tackling" (ropes and gear), "corn" (grain for food). Pairs read Source 3, reread the second paragraph of Source 2, and answer the five relationship questions about the storm and the tide.

    XXVIII.--A peace being established by these proceedings four days after we had come into Britain, the eighteen ships, to which reference has been made above, and which conveyed the cavalry, set sail from the upper port with a gentle gale; when, however, they were approaching Britain and were seen from the camp, so great a storm suddenly arose that none of them could maintain their course at sea; and some were taken back to the same port from which they had started;--others, to their great danger, were driven to the lower part of the island, nearer to the west; which, however, after having cast anchor, as they were getting filled with water, put out to sea through necessity in a stormy night, and made for the continent.

    XXIX.--It happened that night to be full moon, which usually occasions very high tides in that ocean; and that circumstance was unknown to our men. Thus, at the same time, the tide began to fill the ships of war which Caesar had provided to convey over his army, and which he had drawn up on the strand; and the storm began to dash the ships of burden which were riding at anchor against each other; nor was any means afforded our men of either managing them or of rendering any service. A great many ships having been wrecked, inasmuch as the rest, having lost their cables, anchors, and other tackling, were unfit for sailing, a great confusion, as would necessarily happen, arose throughout the army; for there were no other ships in which they could be conveyed back, and all things which are of service in repairing vessels were wanting, and corn for the winter had not been provided in those places, because it was understood by all that they would certainly winter in Gaul.

    Julius Caesar, translated by W. A. McDevitte, The Gallic War, Book IV, chapters XXVIII-XXIX (Source 3: the storm and the high tide) (1915). Public domain (published 1915). Source text.

    Pair task. (a) What does Dickens borrow from paragraph 1? (b) What does he change in paragraph 2? (c) What does Caesar include that Dickens leaves out? (d) Dickens says Caesar "ran great risk of being totally defeated." Is that Caesar's statement or Dickens's judgment, and does Source 3 support it? (e) Why might each writer tell the storm the way he does?

    Teacher model: (a) Dickens borrows the cavalry's failure: Caesar says the cavalry ships met "so great a storm" that "none of them could maintain their course," and Dickens writes that the horse-soldiers "had been driven back by a storm." (b) Caesar describes two different disasters at once: the full-moon tide filled the warships "drawn up on the strand," and the storm dashed the transports "riding at anchor against each other." Dickens combines them into one: vessels "dashed to pieces by a high tide after they were drawn ashore." (c) Dickens leaves out the full moon, the fact that the tides were "unknown to our men," and the army's lack of grain and repair tools. (d) It is Dickens's judgment. Source 3 partly supports it: "there were no other ships in which they could be conveyed back," and "a great confusion" spread through the army. But Caesar never says he nearly lost. (e) Dickens shortens the story for young readers. Caesar, reporting to Rome, explains the losses as bad luck with a tide nobody knew about, which also protects his own reputation as a commander.

  4. Independent Practice15-20 minutes

    Students read two new passages on their own and use them for the quiz. Source 4 is Caesar's description of how the Britons fought from chariots (light two-wheeled carts pulled by horses), from later in the first invasion. Source 5 is Dickens's description of the same chariots, from earlier in his chapter. Students fill in a five-question organizer as they read, one row for each relationship question. Gloss: "infantry" (foot soldiers), "pole" (the long wooden bar between the two horses), "yoke" (the crossbar over the horses' necks), "celerity" (speed), "seasonably" (at the right moment), "spoil" (goods taken in war), "break them in" (train horses), "standard" (flag or emblem).

    XXXIII.--Their mode of fighting with their chariots is this: firstly, they drive about in all directions and throw their weapons and generally break the ranks of the enemy with the very dread of their horses and the noise of their wheels; and when they have worked themselves in between the troops of horse, leap from their chariots and engage on foot. The charioteers in the meantime withdraw some little distance from the battle, and so place themselves with the chariots that, if their masters are overpowered by the number of the enemy, they may have a ready retreat to their own troops. Thus they display in battle the speed of horse, [together with] the firmness of infantry; and by daily practice and exercise attain to such expertness that they are accustomed, even on a declining and steep place, to check their horses at full speed, and manage and turn them in an instant and run along the pole, and stand on the yoke, and thence betake themselves with the greatest celerity to their chariots again.

    XXXIV.-Under these circumstances, our men being dismayed by the novelty of this mode of battle, Caesar most seasonably brought assistance; for upon his arrival the enemy paused, and our men recovered from their fear; upon which, thinking the time unfavourable for provoking the enemy and coming to an action, he kept himself in his own quarter, and, a short time having intervened, drew back the legions into the camp. While these things were going on, and all our men engaged, the rest of the Britons, who were in the fields, departed. Storms then set in for several successive days, which both confined our men to camp and hindered the enemy from attacking us. In the meantime the barbarians despatched messengers to all parts and reported to their people the small number of our soldiers, and how good an opportunity was given for obtaining spoil and for liberating themselves for ever, if they should only drive the Romans from their camp. Having by these means speedily got together a large force of infantry and of cavalry, they came up to the camp.

    Julius Caesar, translated by W. A. McDevitte, The Gallic War, Book IV, chapters XXXIII-XXXIV (Source 4: the British chariots) (1915). Public domain (published 1915). Source text.

    They were very fond of horses. The standard of Kent was the picture of a white horse. They could break them in and manage them wonderfully well. Indeed, the horses (of which they had an abundance, though they were rather small) were so well taught in those days, that they can scarcely be said to have improved since; though the men are so much wiser. They understood, and obeyed, every word of command; and would stand still by themselves, in all the din and noise of battle, while their masters went to fight on foot. The Britons could not have succeeded in their most remarkable art, without the aid of these sensible and trusty animals. The art I mean, is the construction and management of war-chariots or cars, for which they have ever been celebrated in history. Each of the best sort of these chariots, not quite breast high in front, and open at the back, contained one man to drive, and two or three others to fight—all standing up. The horses who drew them were so well trained, that they would tear, at full gallop, over the most stony ways, and even through the woods; dashing down their masters’ enemies beneath their hoofs, and cutting them to pieces with the blades of swords, or scythes, which were fastened to the wheels, and stretched out beyond the car on each side, for that cruel purpose. In a moment, while at full speed, the horses would stop, at the driver’s command. The men within would leap out, deal blows about them with their swords like hail, leap on the horses, on the pole, spring back into the chariots anyhow; and, as soon as they were safe, the horses tore away again.

  5. Closure5-10 minutes

    Exit ticket: On an index card, finish two sentences: "A secondary source can ___ a primary source, for example ___." and "It matters because ___." Collect the cards and read three aloud at the start of the next lesson.

    Teacher note on the sources: The passages are quoted exactly as printed in 1905 and 1915. In Sources 1 and 4, Caesar calls the Britons "barbarians," his usual word for peoples outside the Greek and Roman world. Point out that the word reflects Roman attitudes: Romans saw outsiders as less civilized than themselves, and the word tells us about Caesar's point of view, not about the Britons. Other paragraphs of Dickens's chapter, not printed here, describe the early Britons in insulting terms that were common in his time. Dickens calls the year "fifty-five years before the birth of Our Saviour," the Christian way of counting years that the page writes as 55 BC. Caesar's figures are his own and cannot always be checked; his account is the main surviving source for these invasions, which is why the relationship between his account and later histories matters so much.

    Homework passages. Source 6 is Caesar's account of the start of his second invasion, in 54 BC, and Source 7 is Dickens's paragraph on the same campaign, which follows Source 2 in his chapter. Gloss: "Labienus" (one of Caesar's generals), "horse" (cavalry), "extolled" (praised), "maritime states" (British peoples along the coast), "perpetual" (constant).

    VIII.--When these things were done [and] Labienus, left on the continent with three legions and 2000 horse, to defend the harbours and provide corn, and discover what was going on in Gaul, and take measures according to the occasion and according to the circumstance; he himself, with five legions and a number of horse, equal to that which he was leaving on the continent, set sail at sunset and [though for a time] borne forward by a gentle south-west wind, he did not maintain his course, in consequence of the wind dying away about midnight, and being carried on too far by the tide, when the sun rose, espied Britain passed on his left. Then, again, following the change of tide, he urged on with the oars that he might make that port of the island in which he had discovered the preceding summer that there was the best landing-place, and in this affair the spirit of our soldiers was very much to be extolled; for they with the transports and heavy ships, the labour of rowing not being [for a moment] discontinued, equalled the speed of the ships of war. All the ships reached Britain nearly at mid-day; nor was there seen a [single] enemy in that place, but, as Caesar afterwards found from some prisoners, though large bodies of troops had assembled there, yet being alarmed by the great number of our ships, more than eight hundred of which, including the ships of the preceding year, and those private vessels which each had built for his own convenience, had appeared at one time, they had quitted the coast and concealed themselves among the higher points.

    [...]

    When he had come thither, greater forces of the Britons had already assembled at that place, the chief command and management of the war having been entrusted to Cassivellaunus, whose territories a river, which is called the Thames, separates from the maritime states at about eighty miles from the sea. At an earlier period perpetual wars had taken place between him and the other states; but, greatly alarmed by our arrival, the Britons had placed him over the whole war and the conduct of it.

    But, in the spring of the next year, he came back; this time, with eight hundred vessels and thirty thousand men. The British tribes chose, as their general-in-chief, a Briton, whom the Romans in their Latin language called Cassivellaunus, but whose British name is supposed to have been Caswallon. A brave general he was, and well he and his soldiers fought the Roman army! So well, that whenever in that war the Roman soldiers saw a great cloud of dust, and heard the rattle of the rapid British chariots, they trembled in their hearts. Besides a number of smaller battles, there was a battle fought near Canterbury, in Kent; there was a battle fought near Chertsey, in Surrey; there was a battle fought near a marshy little town in a wood, the capital of that part of Britain which belonged to Cassivellaunus, and which was probably near what is now Saint Albans, in Hertfordshire. However, brave Cassivellaunus had the worst of it, on the whole; though he and his men always fought like lions. As the other British chiefs were jealous of him, and were always quarrelling with him, and with one another, he gave up, and proposed peace. Julius Cæsar was very glad to grant peace easily, and to go away again with all his remaining ships and men. He had expected to find pearls in Britain, and he may have found a few for anything I know; but, at all events, he found delicious oysters, and I am sure he found tough Britons—of whom, I dare say, he made the same complaint as Napoleon Bonaparte the great French General did, eighteen hundred years afterwards, when he said they were such unreasonable fellows that they never knew when they were beaten. They never did know, I believe, and never will.

Differentiation Strategies

For Struggling Students

  • Give students Diagram 1 as a bookmark and have them answer one relationship question per reading, starting with borrows
  • Pre-highlight the matching sentences in Sources 3 and 2 so students compare two short pieces at a time
  • Give sentence frames: "Dickens borrows ___ from Caesar's words ___." "Dickens adds ___, which Caesar does not mention."

For Advanced Students

  • Read Caesar's chapter XX, just before Source 1, and decide whether Dickens's reason for the invasion matches Caesar's
  • Find a modern encyclopedia article on Caesar's invasions of Britain and analyze its relationship to Caesar's account
  • Write a short note to Dickens pointing out one place where his history goes beyond Caesar's evidence

Assessment Guidance

What to Look For

Strong work names the kind of relationship (borrows, adds, leaves out, changes) for each detail and supports it with exact words from both sources, then explains why the writers differ. Watch for four errors: assuming that an older text is always a primary source; treating any detail in the secondary source as proof that the primary source said it; calling every addition false instead of asking what evidence supports it; and describing the differences without explaining them through each writer's purpose, time and readers.

Classroom Activities

3 Activities

1

Borrowed, Changed, Added or Left Out?

15 minGroups of 3

Each group gets 8 relationship cards. Some cards pair a sentence from Caesar with a sentence from Dickens's Source 2; others give a detail from only one of them. Groups sort the cards into four piles, borrowed, changed, added (in Dickens only) and left out (in Caesar only), and write one sentence for each card explaining the choice.

The 8 Relationship Cards

  1. Caesar, chapter XX: "in almost all the wars with the Gauls succours had been furnished to our enemy from that country." Dickens: the Britons, "some of whom had been fetched over to help the Gauls in the war against him."
  2. Caesar, chapter XXII: "about eighty transport ships, as many as he thought necessary for conveying over two legions." Dickens: "with eighty vessels and twelve thousand men."
  3. Caesar, chapter XXXVI: he sailed home because "the time of the equinox was near" and his ships were "out of repair." Dickens: "he was very glad to accept their proposals of peace, and go away."
  4. Caesar, chapter XXVI: "The battle was maintained vigorously on both sides." Dickens: "the bold Britons fought most bravely."
  5. Dickens only: "just for the same reason as our steam-boats now take the same track, every day."
  6. Dickens only: the Romans "were masters of all the rest of the known world."
  7. Caesar only, chapter XXV: the warships were moved to the enemy's open side, and the Britons, "startled by the form of our ships," pulled back.
  8. Caesar only, chapter XXIII: "the sea was confined by mountains so close to it that a dart could be thrown from their summit upon the shore."

Answer Key for the Teacher

  • Borrowed: cards 1 and 4. Card 1 restates Caesar's reason for the war; card 4 keeps Caesar's point that both sides fought hard, though Dickens gives the praise only to the Britons.
  • Changed: cards 2 and 3. Card 2 keeps Caesar's eighty ships but turns "two legions" into a head count Caesar never gives. Card 3 changes the reason for leaving: Caesar names the season and his damaged ships, while Dickens suggests relief at escaping.
  • Added: cards 5 and 6. The steam-boats are from Dickens's own time, and "masters of all the rest of the known world" is his exaggeration; Caesar had not yet finished conquering Gaul.
  • Left out: cards 7 and 8. Dickens skips the Roman warships and the cliffs.

Procedure

  • Read each card aloud and ask the matching relationship question
  • Place it in a pile and write the reason on a sticky note
  • If the group disagrees, keep the card aside with both reasons
  • Compare piles with another group, then discuss the set-aside cards as a class

Discussion Questions

  • Card 4 could also go in the changed pile. What would you have to argue to put it there?
  • Why might Dickens add a comparison to steam-boats for readers in 1851?

Variation for a Shorter Class

Use cards 1, 3, 5 and 7 only, one for each pile.

2

Whose Side Is the Writer On?

15 minPairs

Pairs highlight every word in Sources 1 and 2 that shows which side the writer is on, in two colors, one for each source. Then they explain how each writer's side shapes the same landing, and how Dickens could praise the Britons while using a Roman general's account.

Procedure

  • Highlight point-of-view words in Source 1 in one color and in Source 2 in another
  • Make a T-chart: "Caesar's side" and "Dickens's side"
  • For each source, write one sentence: whom does the writer want the reader to admire?
  • Answer: Which details in Source 1 could Dickens use to admire the Britons?

Answer Key for the Teacher

  • Caesar's side: "our men," "our ships," "the enemy"; the Romans are the heroes, with the eagle-bearer's shout and Caesar's quick orders to the warships.
  • Dickens's side: "this Island of ours," "the bold Britons"; the Britons are the heroes, and Caesar is the one surprised.
  • Using Caesar for the Britons: Caesar himself reports that the Britons fought "in places thoroughly known to them" and "could confidently throw their weapons and spur on their horses," and that his men "did not all exert the same vigour." Dickens reads that evidence in the Britons' favor.

Discussion Questions

  • Caesar admits his men were afraid. Why might a writer include a fact that does not flatter his own side?
  • Is a secondary writer who takes the other side more trustworthy, less trustworthy or neither?

Modification for English Learners

Give pairs a word bank (we, our, ours, us, the enemy, bold, brave) and have them circle only those words before writing the T-chart sentences with a frame: "Caesar wants us to admire ___ because ___."

Be the Secondary Source

15 minGroups of 3, then pairs of groups

Each group writes a short secondary source: a 4-5 sentence account of the landing in Source 1 for a modern grade 6 textbook. The rules: borrow at least one detail with quotation marks, leave out at least one detail on purpose, and add one piece of background a modern reader needs. Groups then swap accounts and run the five relationship questions on each other's work.

Procedure

  • Decide your readers and purpose in one sentence before writing
  • Write the account on chart paper, underlining the quoted words
  • Swap with another group and label what they borrowed, added, left out and changed
  • Return the account with one question about a choice the writers made

Sample Account for the Teacher

"In 55 BC the Roman general Julius Caesar tried to land an army in Britain. His large ships had to stay in deep water, so his soldiers, weighed down by armor, had to jump into the waves while British warriors attacked from the beach. According to Caesar, the soldier who carried the legion's eagle, its sacred standard, leaped first and shouted, 'Leap, fellow soldiers [...].' The rest followed him. Caesar's account is the main source for this landing, so we see it mostly through Roman eyes." This sample borrows the eagle-bearer and quotes him, leaves out the warships and the engines, adds what an eagle was, and changes the emphasis by naming whose view the story comes from.

Discussion Questions

  • What was hardest to leave out, and why did you leave it out anyway?
  • How did knowing your readers change what you borrowed?

Modification for Advanced Students

Groups write a second version of the same account for a different reader, such as a museum sign in Rome or a British newspaper in 1851, and explain how the relationship to Source 1 changed.

Diagram 1: Five Relationship Questions

Five questions that link a secondary source to its primary source PRIMARY SOURCE Caesar, The Gallic War by the commander, 50s BC SECONDARY SOURCE Dickens, A Child’s History of England, 1851 used as a source 1,905 years later BORROWS What does the secondary source take from the primary source? Example: Dickens quotes Caesar’s reason for his route (Source 2) ADDS What is in the secondary source but not in the primary source? Example: "He expected to conquer Britain easily" (Dickens only) LEAVES OUT What is in the primary source but missing from the secondary? Example: the eagle-bearer’s leap (Source 1) is not in Dickens CHANGES What is reworded, combined or given a new emphasis? Example: Caesar blames deep water; Dickens praises "the bold Britons" WHY? What explains each difference: time, purpose, readers, sources? Example: Caesar reports his own war; Dickens writes for British children
Five questions for analyzing how a secondary source relates to a primary source on the same topic. Each example comes from Sources 1 and 2 and the worked examples; the last question asks why the two writers differ.

Diagram 2: The Distance in Time Between the Sources

How far apart in time are the two sources? 100 BC 500 1000 1500 2000 55 and 54 BC Caesar invades Britain twice About AD 121 Suetonius on Caesar and pearls AD 43 Claudius invades Britain 1851 Dickens’s history begins 1915 this translation printed 1,905 years between the first landing (55 BC) and Dickens’s first chapter (1851)
A timeline drawn to scale from 100 BC to AD 2000. Caesar's two invasions (55 and 54 BC) and Dickens's first chapter (1851) are 1,905 years apart, since there is no year 0. The marks for Claudius's conquest (AD 43) and the Roman writer Suetonius (about AD 121) show that Dickens could also draw on sources other than Caesar.

Homework Assignment

RH.6-8.9 Homework: The Second Invasion in Two Sources

Directions: Read Source 6 (Caesar on his second invasion, 54 BC) and Source 7 (Dickens on the same campaign), both printed at the end of the Closure phase of the lesson plan. Problem 4 also uses Source 4. For each problem, quote the exact words you use and give the source and paragraph number. Answer in 2-5 sentences unless the problem asks for more.

Part 1: What Dickens Borrowed and Changed (Problems 1-3)

  1. Dickens says Caesar came back "with eight hundred vessels." Find the sentence in Source 6 that gives this number. What did Dickens keep, and what did he leave out about which ships were counted?
  2. Dickens says Caesar brought "thirty thousand men." Source 6 says Caesar sailed "with five legions and a number of horse, equal to that which he was leaving on the continent," and that he left 2000 horse behind. If a legion at full strength had about 5,000 soldiers, about how many men does that make? Is Dickens's number borrowed from Caesar or his own estimate? Explain.
  3. Compare what Source 6 and Source 7 say about Cassivellaunus. Name one thing Dickens borrows, one thing he adds, and one thing he changes about why the Britons chose him.

Part 2: Why the Accounts Differ (Problems 4-6)

  1. In Source 4, Caesar writes that "our men being dismayed by the novelty of this mode of battle" needed his help. In Source 7, Dickens writes that the Roman soldiers "trembled in their hearts" at the British chariots. How did Dickens change Caesar's idea, and why might he have made the change?
  2. Source 7 ends with Dickens's own comments, such as "I am sure he found tough Britons" and "They never did know, I believe, and never will." What do these comments show about Dickens's purpose and readers? How do they change the relationship between his history and Caesar's account?
  3. Write a paragraph of 5-7 sentences that analyzes the relationship between Source 6 and Source 7. Use at least four of the five relationship questions (borrows, adds, leaves out, changes, why), with a quotation from each source.

Frequently Asked Questions

10 Questions

What does RH.6-8.9 mean?

RH.6-8.9 asks students in grades 6-8 to analyze the relationship between a primary and a secondary source on the same topic. Students work out what the later source borrows from the earlier one, what it adds, leaves out or changes, and why the two differ.

What is the difference between a primary and a secondary source?

A primary source was made by someone who took part in or saw the events, at or near the time: a letter, diary, report, photograph or eyewitness account. A secondary source was made later by someone who was not there, using other sources: a textbook, a history book or a documentary.

Is a translation of a primary source still a primary source?

Yes, as long as it is a translation of the original account; the words and view are still the eyewitness's. A good reader remembers that the translator made choices. On this page, the words in square brackets in Caesar's account were added by the translator, and the reason for the route that Dickens quotes from Caesar is in Caesar's Latin but is left out of chapter XXI of the translation used here.

Can a source be primary for one question and secondary for another?

Yes. Dickens's history is a secondary source about Caesar's invasions, but it is a primary source for how English writers of the 1850s saw their country's past. The question you ask decides which kind of source a text is.

How can a secondary source relate to a primary source?

It can borrow from it (quote or restate it), add to it, leave parts out, change it (reword, combine or shift the emphasis), or disagree with it. Students then ask why: the later writer's time, purpose, readers and other sources usually explain the differences.

Is a secondary source less reliable than a primary source?

Not necessarily. A primary source is close to the events but can be one-sided, as Caesar's account of his own war is. A careful secondary source can compare several primary sources and correct errors. Each kind has strengths, which is why historians read them together.

How is RH.6-8.9 different from RH.9-10.9?

RH.6-8.9 focuses on the link between one primary and one secondary source on the same topic. RH.9-10.9 asks students to compare and contrast treatments of the same topic in several primary and secondary sources, and RH.11-12.9 asks them to combine diverse sources into one understanding while noting where they disagree.

Why use Julius Caesar and Charles Dickens to teach RH.6-8.9?

Caesar's own account is the main surviving source for his invasions of Britain, and Dickens's 1851 history clearly depends on it: he quotes it, borrows its details and argues with its view. Students can trace the relationship line by line. Both texts are in the public domain, and ancient Rome is a common topic in grades 6-8 history.

How can parents help with RH.6-8.9 at home?

Watch a movie or read a book that is "based on a true story," then look up an interview, letter or news report from the real event. Ask together: What did the movie keep? What did it add or leave out, and why might the filmmakers have made those choices?

Which grades and classes teach RH.6-8.9?

RH.6-8.9 covers grades 6, 7 and 8, so it can be taught in any middle school history or social studies course. Teachers often return to it each year with harder pairs of sources, and it prepares students for RH.9-10.9 in high school.
