Ancient Britain and the Invasions of Julius Caesar

by T. Rice Holmes

It was about the 6th of July, probably the day after this episode, when the embarkation took place.[1357] Commius, still friendly to Rome, was to accompany the expedition, as well as Mandubracius, the Trinovantian prince who had placed himself under Caesar’s protection. The slaughter of Dumnorix, following the temporary submission of Indutiomarus, had relieved Caesar from imminent danger: but he knew that to keep a hold on the half-subdued and restless peoples whom he was leaving behind would require all the ability of his ablest lieutenant; and there are indications in his narrative that he hoped, if all went well, to winter in Britain, and thus to find time not merely to deter the Britons from combining with the Gauls, but to conquer the south-eastern part of the country.[1358] Labienus therefore remained in charge of the camp and port with three legions and two thousand cavalry. He was to keep the expeditionary force supplied with corn, ascertain all that was passing in Gaul, and act on his own discretion according to circumstances. Among the divisional commanders that accompanied Caesar was Gaius Trebonius, an intimate friend of Marcus Cicero,[1359] who, two years before, had proposed, in the interests of the triumvirate, the law by which the province of Syria was assigned to Crassus, and the two provinces of Spain to Pompey. Late in the afternoon all was ready for the start, the flotilla lying moored in the harbour with five legions and two thousand cavalry on board. The ebb stream was running slowly down the coast. Towards sunset the hawsers were cast off,[1360] and the ships steered north by west before a light south-westerly wind. The moon was invisible,[1361] but at that time of the year there is no real night in these latitudes; and perhaps, as in the preceding year, each vessel hoisted a lantern when the twilight waned. About ten o’clock the stream began to run up the Channel, and for a time the vessels made good progress. By midnight the leading division was not far off the South Foreland, and somewhere near what is now the southern end of the Goodwin Sands; but it is probable that in steering, sufficient allowance had not been made for the current, and that the shallow flat-bottomed vessels had already drifted to leeward away from their true course. And now the wind, which had been gradually dying down, almost entirely dropped, only retaining The fleet drifts north-eastward out of its course. just sufficient force to give steerage way. Borne along by a rapid flood, the armada drifted into the North Sea; and about a quarter past three, when day broke, Caesar descried the white cliffs of Kingsdown and the South Foreland receding on the port quarter. Right opposite, but hardly discernible, was the low coast on which he had landed in the previous year. We may assume that when he saw where he was drifting he anchored for a time. Presently the stream ceased to run up the Channel, and, after a few minutes’ slack water, the ebb set in.[1362] The Romans had a system of naval signalling,[1363] and either by this means or by oral instructions conveyed from vessel to vessel, the order was given to go about and run down Channel with the stream. The soldiers on board the transports got out their oars. For some time their work was easy; but when, not far from the spot where the South Sand Head Light Vessel is now moored, the ships’ heads were turned in the direction of Sandwich, they encountered a cross current setting towards the south-west.[1364] Although the transports were heavily laden, they toiled with an energy which earned Caesar’s warm admiration, and actually The landing-place, between Sandown Castle and Sandwich, reached by rowing. succeeded in keeping up with the galleys. About noon the whole fleet had reached the landing-place; but no enemy was to be seen, and in the course of the day a galley was speeding back across the Channel with one of Caesar’s couriers on board, who carried, besides other dispatches, a letter in which Quintus Cicero informed his brother that all was well.[1365]

Leaving the fleet at anchor in charge of a brigade, Caesar marches against the Britons,

While the troops and baggage were being disembarked, Caesar chose a site for his camp, perhaps on the slight eminence near the village of Worth. Some prisoners were soon brought in by the cavalry and questioned. They stated that their countrymen had assembled in large numbers to oppose the landing, but that, on observing the huge size of the the armada, they had abandoned the shore and retreated to higher ground inland. Caesar determined to march against them that very night, and accordingly accepted the risk of not hauling his ships up on shore, an operation which would have consumed valuable time. He had not forgotten the disaster of the previous year; but, as the shore where he now left the ships at anchor was not only perfectly open but sloped very gently seaward, he felt little anxiety for their safety.[1366] He mentioned this fact in his memoirs[1367] with an emphasis which suggests that he wished to deprecate professional criticism. Moreover, the storm which had wrought such havoc before had occurred on the night of a full moon: the moon was now new; and it may be doubted whether Caesar had studied the writings of the Greek astronomers, or consulted the pilots, from whom he would have learned that the tides at new and at full moon are virtually identical. Ten cohorts selected from the various legions, or about four thousand men, and three hundred cavalry were left, under the command of an officer named Quintus Atrius, to protect the fleet. Soon after midnight Caesar set out against the enemy. We may presume that he had sent a troop of cavalry in the afternoon to reconnoitre; but he must have trusted to his prisoners for information as to the whereabouts of the British force. It was posted on high ground overlooking Durovernum, the village which stood upon the site of Canterbury, and which the Romans afterwards linked by a system of roads with their settlements at London, Reculver, Richborough, Dover, and Stutfall near West Hythe. The general direction of Caesar’s march is indicated by the road which runs across the gently undulating and somewhat featureless country between Sandwich and Canterbury. He had advanced about eleven miles when, in the early morning, he descried the enemy’s cavalry and charioteers descending from high ground towards the left bank of the Stour. The spot where he encountered them must have been somewhere between Sturry on the east of Canterbury, and Thanington on the west; and military experts who know the country will probably conclude that it was near the latter.[1368] The enemy had doubtless attempted to occupy the whole range of low hills which closes the valley of the Stour between these two points, prepared to oppose the legions wherever they might attempt to cross. It would seem, however, that their resistance was comparatively feeble, perhaps because they were surprised, and, having needlessly strung out their forces, were unable to concentrate in time. Caesar forces the passage of the Stour near Canterbury, may have sent a detachment to turn their position: anyhow they were driven from the banks after a combat which he recorded in a single sentence. Retreating to the higher ground, they took up their position in a stronghold situated in the midst of woods,—probably the earthwork, about a mile and a half west of Canterbury, through which runs the Pilgrims’ Way, and within which, as we have seen, have been discovered iron implements and weapons of pre-Roman age.[1369] The legions, pressing after them, found the entrances blocked by abatis; and when they attempted to force their way in, the Britons, issuing from the woods in small groups, assailed them with showers of missiles. It would appear from Caesar’s narrative that the rampart, or at least a part of it, extended along the edge of the wood. The 7th legion was selected for the assault. Advancing in a dense column, with shields close-locked over their heads, they shot earth or fascines into the ditch so as to form a causeway flush with the top of the rampart; and it may be conjectured that the work was performed by men who advanced between the files under the protection of their comrades’ uplifted shields.[1370] and storms a fort, to which they had retreated. In this way the entrenchment, which, like all the British forts that Caesar saw, was weaker than the great strongholds of Western Britain, was speedily captured with small loss; and the Britons were expelled from the woods. The legionaries followed up their success, but Caesar soon stopped the pursuit. He was afraid to run the risk of letting his troops get entangled in a wooded country, of the intricacies of which he was ignorant; and, as it was late in the afternoon, he was obliged to utilize the remaining hours of daylight for the construction of his camp.

Next morning he sends three columns in pursuit,

Early next morning he dispatched his cavalry in three columns, each supported by a strong body of infantry, to hunt down the fugitives. The pursuers had advanced a considerable distance from the camp, the rearguard being still in sight,[1371] when some troopers rode up to Caesar with a note from Atrius. A storm had arisen on the previous night: the ships had parted from their anchors, collided with one another, and almost all been dashed ashore and damaged. but is forced to recall them by news that many of his ships had been wrecked. Caesar sent gallopers to recall the pursuing columns, and order them to march back to the coast, defending themselves, if necessary, against a counter-attack, and started in person for the scene of the wreck.[1372] When he arrived, he found that Atrius’s report was accurate: about forty ships were totally destroyed; but, after inspecting the rest, he saw that it would be possible to repair them. In the course of the day the legions arrived. The men who had enlisted as skilled craftsmen were segregated and set to work; and galleys were sent to Labienus with a letter in which he was ordered to dispatch gangs of shipwrights from his three legions, and to employ the rest of the men in building new He beaches the ships, constructs a naval camp, and repairs damage. vessels. Caesar reluctantly concluded that the only way of preventing another disaster was to have all the ships hauled up on land out of reach of the highest spring tides. They were doubtless moved in the usual way, by capstans over greased logs, which the Romans called phalangae;[1373] and then, in order to secure them against attack, an earthwork was thrown up round them, and connected with the existing camp. The amount of labour which these operations entailed was enormous: but there were some twenty thousand willing workers; and by employing them in relays all day and all night, Caesar was able to complete the task in about ten days. The repairs of course required a longer time.

Results of the disaster.

This second shipwreck was a calamity of which the mere loss in ships formed the smallest part. It changed the course of the campaign. Why had not Caesar restrained his eagerness to close with the enemy, and employed every available man in beaching the vessels which he had constructed with that very aim? Granted that it might not have been possible to complete even the mere work of dragging them all out of reach of the waves before the storm began, he would still have done right in not presuming upon the favour of fortune. Nobody knew better how necessary it is, especially in making war upon a half-civilized enemy, to complete all preparations, even at the cost of delay, before opening the campaign, so as to lose not a moment in following up an initial success, and to give fugitives no time to recover from their demoralization. Less than two days after he set foot in Britain he had dealt the enemy a succession of heavy blows, and the game was in his hands,—when all that he had done was undone by his own carelessness. Britons saw Romans in full retreat, and concluded that they were not invincible.

Caesar again marches towards Canterbury. Cassivellaunus elected commander-in-chief of the Britons.

By the time when the naval camp was finished the season was far advanced. It was near the end of the third week in July when Caesar was able to renew his campaign. The Britons had made good use of their respite. The tribes had suspended their feuds: Cassivellaunus had been called upon by a general assembly of notables[1374] to undertake the chief command with full powers; and a large force, composed of contingents from all, or almost all, the cantons of the south-eastern district, had marched to join the men of East Kent. We may doubt whether the Trinovantes had not held aloof; but if they had been forced to join the league, they were half-hearted. It is certain that, before Caesar had been long in the island, they sent envoys, promising submission and begging him to send Mandubracius back to them as their ruler and to protect him against Cassivellaunus. He allowed Mandubracius to depart, only stipulating that the Trinovantes should give him forty hostages and provide grain for his army; and readers who can interpret the Commentaries will conclude that the embassy was dispatched before he had advanced far into the interior, and doubtless as soon as he had proved his superiority. He left the same force as before—ten cohorts and three hundred cavalry—to protect the camp, and marched once more in the direction of Canterbury. As he was approaching the valley of the Stour, the enemy’s cavalry and charioteers commenced a fierce running fight with his Gallic cavalry; but they were beaten back at all points and driven to take refuge on the The Romans harassed by British charioteers. wooded heights near the river. The Gallic cavalry, however, over-eager to pursue, and getting entangled in ground which was unknown to them, suffered considerable loss; and soon afterwards, while the legionaries, careless of danger, were engaged in entrenching their camp, the enemy suddenly swooped down upon the cohort on guard and began to overpower it. Caesar had not yet learned due respect for his enemy; otherwise he would have kept a much more powerful force, as he had done on a similar occasion in Gaul, to protect the working-parties. He sent two cohorts, however, to support the struggling guard and cut off the retreat of the assailants. These reinforcements were separated from one another by a narrow interval: the men who composed them, and who had not served in the preceding year, were unnerved by the novel tactics of the charioteers; and the enemy boldly rushed through the interval, and got back to the main body unhurt. Several additional cohorts, accompanied by cavalry, were sent to retrieve the situation. The combat was clearly visible from the camp; and Caesar saw that his troops, who had so often routed their continental enemies, were at a serious disadvantage. The Britons fought not in close order but in small groups, separated by wide intervals; and when these were tired, their places were taken by reserves. Whenever a group was hard pressed by the legionaries, the men who composed it ran away: the Romans, weighted by their heavy armour, were ineffective in pursuit; and, besides, accustomed as they were to fight in compact masses, they and their officers naturally failed to adapt themselves to new conditions. Again, when the Gallic cavalry charged the charioteers, the latter drove rapidly away; and, as soon as they had withdrawn their assailants from the support of the legions, the warriors leaped to the ground, and, supported by their own cavalry, fought as infantry, with the odds in their favour.[1375] A tribune named Quintus Laberius Durus was killed; but at length the reinforcements which Caesar sent up succeeded in beating back the Britons, or at all events deterring them for the moment from renewing their attack.

All this time Caesar was doubtless fighting to gain the line of the road or trackway by which he would have to march westward into the interior of Britain and assail the dominions of Cassivellaunus. But it was of course out of the question to begin his march until he had inflicted a crushing defeat upon the allies; and, as he saw now, their game was to avoid a general action. On the following day, however, a chance presented itself. In the morning the enemy, who had taken up a position on the heights at some distance from the Roman camp, moved down, as before, in scattered groups, and began to assail the cavalry outposts, but with somewhat diminished vigour. The outposts fell back; and presently the whole of the cavalry were sent out, along with three of the legions, under Gaius Trebonius, on a foraging expedition. Part of the force proceeded to cut grass, while the rest remained drawn up in support. Suddenly the enemy rushed down from all points on the foragers, and, made reckless by success, ‘did not even hesitate,’ as Caesar wrote, ‘to attack the ordered ranks of the legions.’[1376] Trebonius routs the Britons. The Romans charged them fiercely, and took ample revenge for the previous day. The Britons were driven from the field, hotly pursued by Trebonius and his men, until the Gallic cavalry, relying upon the support of the legions, which still followed as closely as they could, hunted them in headlong rout, cutting them down in numbers, and never giving them a chance of rallying. Not even the charioteers could get a moment’s respite, or dared to dismount and turn The British infantry disperse. upon their pursuers. This defeat was decisive. The tribal levies of foot at once dispersed to their homes; and ‘from that time’, wrote Caesar, ‘the enemy never encountered us in a general action.’[1377]
