Ancient Britain and the Invasions of Julius Caesar

Caesar had learned the lessons which failure had taught Caesar builds a fleet for a second expedition. him. In the winter he was obliged, as usual, to go to Cisalpine Gaul, partly in order to discharge judicial and administrative business, partly to safeguard his own political interests in Italy. Before he left Belgium he ordered his generals to employ the legions in repairing the old ships and building a new fleet for the second expedition. He drew up minute instructions for their guidance. Two thousand cavalry horses, besides transport cattle, were to be conveyed across the Channel; and, as the campaign would probably be protracted, it would be impossible to leave all the heavy baggage behind, and imprudent to trust again for supplies to the resources of the country.[1337] The ships were to be somewhat shallower than those which were commonly used in the Mediterranean, in order to facilitate the work of loading and to enable them to be hauled up on the shore: on the other hand, to make room for troops and freight, they were to be rather broader in the beam. Their low freeboard would admit of their being constructed for rowing as well as sailing;[1338] and Caesar, who had noticed that the waves in the Channel were comparatively small, thought that it would involve no danger. But this shallowness, combined with unusual breadth, entailed a disadvantage which he had perhaps not foreseen: it would cause the vessels, unless the wind were right aft or on the quarter, to make a great deal of leeway.[1339] It was of course impossible to build such a large flotilla in one port. Some of the ships were to be constructed in the mouth of the Seine: others doubtless in the Portus Itius itself; others probably in the Canche, the Authie, and the Somme, possibly even on the Marne, far from the sea-coast.[1340] The legionaries were ill provided with appliances for ship-building: but they might be trusted to do their best; and the tackle necessary for rigging and equipping the fleet was to be imported from Spain. The cost of the expedition would be very heavy: but Caesar was amassing wealth for himself and his lieutenants by plundering Gaul; and he certainly hoped to do more in Britain than recover his expenses.[1341]

News of these preparations must of course have flown swiftly across the Channel; but it is hardly surprising that the British chieftains did not take advantage of the time that was given them to mature a scheme of defence. Cassivellaunus was still intent on self-aggrandisement; and in the struggle with his neighbours, the Trinovantes, he slew Mandubracius flees from Britain and takes refuge with Caesar. their king, whose son, Mandubracius, contrived to escape, took ship for Gaul, and presented himself—the first of a series of British exiles who invited Roman interference—in Caesar’s camp. The exact date of his flight cannot be given: it is sufficient to know that he was with Caesar when the time arrived for the Roman army to embark.

Caesar winters in Cisalpine Gaul and Illyricum.

Caesar did not start for Italy until the middle of November,[1342] and after he had fulfilled the civil duties which awaited him in Cisalpine Gaul he was obliged to travel to the further shore of the Adriatic in order to punish a tribe which had been making devastating raids upon Illyricum. In the early spring he was again in Cisalpine Gaul, clearing off arrears of His correspondence with Cicero. work, and preparing to recross the Alps. Cicero for whom he had an unfeigned admiration, and whom he was always endeavouring to conciliate, was now upon the best of terms with him; and his correspondence throws a ray of light upon the hopes which had been awakened in Italy by the preparations for a fresh expedition to Britain. Caesar was of course beset with letters of recommendation written by public men on behalf of friends who hoped to acquire riches in Gaul or Britain; and Cicero wrote one, as he alone knew how to write, begging him to do something for a young lawyer, named Trebatius, who was destined to achieve distinction as a jurist. Caesar, however pressed with business he might be, received all such applications, when they came from men whom he cared to conciliate, with good humour. ‘Just as I was speaking,’ wrote Cicero, ‘to our friend Balbus at my house, a letter from you was handed to me, at the end of which you say: “Rufus, whom you recommend to me, I will make King of Gaul.... Send me some one else to provide for!” ... I therefore send you Trebatius.’[1343] The confiding lawyer wanted to make a fortune without having to work for it: but Cicero banteringly told him to moderate his expectations. ‘I hear,’ he wrote, ‘there is no gold or silver in Britain. If so, I advise you to capture a war-chariot and come back in it as soon as you can.’[1344] He ended his letter by telling Trebatius that if he wished to cultivate Caesar’s friendship, he must take the trouble to make himself useful. Caesar bestowed upon him the rank of tribune, exempting him from military duty, for which he was manifestly unfit; but, after a short experience of camp life, he made up his mind that the expedition would involve more hardship than profit, and preferred to remain in Gaul. But Caesar had gained another adherent who turned out a real soldier. Quintus Cicero, the orator’s younger brother, had consented to serve on his staff as a legatus, or general of division;[1345] and a few words from a letter in which this consent is alluded to illustrate the gracious tact which helped Caesar to gain adherents. ‘Caesar,’ writes Marcus Cicero to his brother, ‘has written to Balbus that the little bundle of letters in which mine and Balbus’s were packed was so saturated with rain when it was delivered to him that he was not even aware that there was one from me. However, he had made out a few words of Balbus’s, to which he replied as follows:—“I see you have written something about [Quintus] Cicero, which I have not deciphered: but as far as I could guess, it was of a kind that I might wish, but hardly hope to be true.”’[1346] On the 30th of April Quintus was with Cicero’s hopes and fears about the second British expedition. Caesar at Blandeno, a small town near Placentia. Marcus knew of course that Quintus was to accompany the expedition to Britain; and he indulged the fancy that Caesar’s exploits would furnish him with a theme for a heroic poem. ‘Only give me Britain,’ he wrote to Quintus, ‘to paint in colours supplied by you, but with my own brush.’[1347] But he must have soon received discouraging news; for early in June[1348] he wrote to Atticus:—‘The result of the British expedition is a source of anxiety. For it is notorious that the approaches to the island are ramparted by astonishing masses of cliff; and, besides, it is now known that there isn’t a pennyweight of silver in the island, nor any hope of loot except from slaves; and I don’t suppose you expect any of them to be a scholar or a musician.’[1349]

Caesar returns to Gaul.

By this time Caesar and his new lieutenant, having posted across Gaul at the rate of fifty miles a day or more,[1350] must have reached the country of the Belgae; and there is no more conclusive proof of the hold which he had already obtained upon the Gallic tribes than the fact that he was able to count, as securely as in Italy, upon finding horses ready for each successive stage. He immediately proceeded to inspect the various shipyards, near which the troops were encamped, and was well satisfied with the manner in which his instructions had been executed. ‘Thanks,’ he wrote, ‘to the extraordinary energy of the troops, and in spite of the extreme deficiency of resources, about six hundred vessels of the class specified and twenty-eight ships of war had been built, and would probably be ready for launching in a few days.’[1351] Caesar, who knew the stimulating power of discriminative praise, bestowed hearty commendation upon officers and men, and gave orders that the ships, as soon as they were ready for sea, should all assemble in the Portus Itius. For this purpose he detached an adequate He is obliged to march to the country of the Treveri. number of troops. Meanwhile his presence was urgently required in the country of the Treveri, a powerful tribe who inhabited parts of Luxembourg and Rhenish Prussia, and whose name survives in that of the modern Trèves. A squadron of cavalry furnished by this people had served on his side in the battle with the Nervii, and had deserted in a body at a moment when it seemed that he was doomed to defeat. Since that day the Treveri had refused to send representatives to attend the councils of Gallic magnates which he periodically convened; and he was now informed that they were making overtures to the Germans. Unless he recalled them to obedience, it was more than probable that while he was absent in Britain, Gauls and Germans would raise a rebellion in his rear. Accordingly, he marched against the malcontents with four lightly equipped legions and eight hundred cavalry. Fortunately for him the Treveri were not unanimous. Two rival leaders, Indutiomarus and Cingetorix, were struggling for supremacy. Cingetorix at once threw in his lot with Caesar, and gave him full information of all that was going on. Indutiomarus began to raise levies, and prepared to resist; but, finding that most of his fellow chieftains were going over to the stronger side, he sent envoys to Caesar, and endeavoured to explain away his conduct. Unwilling to lose time, Caesar feigned to accept his excuses, and contented himself with taking hostages for his good behaviour.

Returning to the Portus Itius, he finds fleet and army assembled.

It was near the middle of June when he returned to the camp on the Liane. More than eight hundred vessels of all sorts were in the harbour, including numerous small craft, constructed by rich officers who desired to make the voyage in comfort, by merchants who had dealings with the troops, or by adventurers who, we may suppose, had been attracted by stories of the wealth of Britain;[1352] but sixty of Caesar’s ships had encountered contrary winds, and failed to arrive.[1353] The entire Roman army, comprising eight legions, perhaps about thirty-five thousand men, besides slingers, archers, and four thousand Gallic cavalry, were assembled on the spot. The notables from all the tribes had also repaired He resolves to take Gallic chiefs of doubtful fidelity as hostages to Britain. thither in obedience to Caesar’s summons. He was aware that there was much smouldering discontent among them, and he intended to take all but the few on whose fidelity he could depend, as hostages across the Channel. Among these was one whose name, as written by Caesar, was Dumnorix, and whose coins, bearing the legend DUBNOREIX,[1354] still testify to the authority which he exercised. He was the most powerful chieftain of the Aedui, the most powerful Gallic tribe, whose territories, corresponding with the Nivernais and Western Burgundy, gave access to all parts of Northern and Western Gaul; who, from the time when the legions first entered Transalpine Gaul, had borne the honorary title of ‘Friends and Allies of the Roman People’; and whom it had been Caesar’s constant policy to treat with special favour. Dumnorix was the leader of the anti-Roman faction which existed in this as in almost every other Gallic tribe. He was a man of boundless ambition, the vehemence of whose character was out of all proportion with his judgement: he had amassed great wealth, which enabled him to maintain an army of retainers; and he had great influence not only with the lower orders in his own country but also with the Gauls of every tribe who wished to rid themselves of the Roman dominion. For the last four years his intrigues had caused anxiety to Caesar. He had been secretly in league with the Helvetian invaders at the time when Caesar marched to encounter them; and in the early part of the campaign his own brother, the famous Druid, Diviciacus, as well as the chief magistrate of his own tribe, had advised Caesar to beware of him. At that time Caesar had not felt sufficiently secure in his new position to punish him; he had simply given him a severe reprimand and a stern warning, but had ever since employed spies to watch his movements. It was now reported that Dumnorix had announced in the Aeduan tribal council that Caesar intended to make him king, and that the announcement had been received with alarm and indignation. There are writers who believe that Caesar had really offered him the throne in order to purchase his support: but it is hardly credible that he would have made such a gross miscalculation; and there is more reason in concluding that Dumnorix had spread a false report in order to estrange the loyal Aeduans from Caesar’s side. At all events he was irreconcilable; Dumnorix resolves not to go. and he determined that to Britain he would not go. He began by imploring Caesar to allow him to remain behind, pleading that he was not accustomed to the sea, and dreaded it, and insisting that he was debarred by religious obligations from leaving the Continent. Finding Caesar obdurate, he approached his brother chieftains, and adjured them to join him in refusing to go, assuring them that Caesar only wanted to get them out of Gaul in order that he might safely put them to death. Caesar did his utmost to keep him quiet, at the same time informing himself through his agents of all The fleet weatherbound. that he said and did. Meanwhile the fleet was lying idle in the harbour. All the preparations were complete: but continuous north-westerly winds made it impossible to sail; and we may safely presume that the troops, who might be required to row the transports, were employed in learning to use their oars. The two Ciceros were in constant correspondence; and the elder brother was impatiently waiting for the announcement that the campaign had begun. On the 2nd of July he wrote to Atticus, ‘Judging from my brother Quintus’s letter, I imagine that by this time he is in Britain. I am anxiously waiting for news of his movements.’[1355] The fleet had been weatherbound then for about three weeks; and the chief of Caesar’s commissariat, who succeeded in feeding forty thousand men for so long a period in an unfriendly country, must have possessed rare powers of organization. At length the wind shifted; and infantry and cavalry began to embark. Suddenly, while every man in the force had his thoughts concentrated on the work in hand, Caesar received news that Dumnorix and his Aeduan troopers had gone. Instantly he stopped the embarkation; and a strong detachment of cavalry was soon riding in pursuit with orders to bring Dumnorix back, or, if he resisted, to kill him on the spot: for, as Caesar afterwards said, ‘he thought that a man who disregarded his authority when he was present would not behave rationally in his absence.’[1356] The fate of Dumnorix. Adjuring his retainers to be true to him, Dumnorix resisted desperately; but he was surrounded and slain, passionately crying with his last breath that he was a free man and a citizen of a free country.

Caesar sets sail, leaving Labienus in charge of Gaul.
