II. Hoping that he had pacified the country by these measures, Cæsar proceeded with his four legions to the Portus Itius. His fleet, perfectly equipped, was ready to sail. Including the vessels of the preceding years, it was composed of six hundred transport ships and twenty-eight galleys. It wanted only forty ships built in the country of the Meldæ,[389] which a tempest had driven back to their point of departure; adding to it a certain number of light barques which many chiefs had caused to be built for their own personal usage, the total amounted to 800 sail.[390] The Roman army concentrated at Boulogne consisted of eight legions and 4,000 cavalry raised in the whole of Gaul and in Spain;[391] but the expeditionary body was composed only of five legions and 2,000 cavalry. Labienus received orders to remain on the coast of the Channel with three legions, and one-half of the cavalry, to guard the ports, provide for the supply of the troops, keep watch upon Gaul, and act according to circumstances. Cæsar had convoked the principal citizens, of each people (principes ex omnibus civitatibus), and left upon the continent but the small number of those of whose fidelity he was assured, taking with him the others as pledges of tranquillity during his absence. Dumnorix, who commanded the Æduan cavalry in the expedition, was of all the chiefs the one it was most important to carry with him. Restless, ambitious, and distinguished by his courage and credit, this man had tried every means in vain to obtain permission to remain in his country. Irritated by the refusal, he became a conspirator, and said openly that Cæsar only dragged the nobles into Britain to sacrifice them. These plots were known and watched with care.
It was the end of June. The wind from the north-west, which on this coast blows habitually at this period of the year, retarded the departure of the fleet twenty-five days; at length a favourable wind rose, and the army received orders to embark. In the middle of the bustle and confusion of starting, Dumnorix left the camp secretly with the Æduan cavalry, and took the road for his own country. When this was known, the embarkment was suspended, and a great part of the cavalry went in pursuit of the fugitive, with orders to bring him back dead or alive. Dumnorix, soon overtaken, resists, and is surrounded and slain. The Æduan cavalry all returned to the camp.
On the 20th of July, we believe, the fleet raised anchor at sunset, with a light breeze from the south-west. This wind having ceased towards midnight, the fleet was carried rather far out of its route by the current of the rising tide. At daybreak, Cæsar perceived that he had left Britain to his left. (See Plate 16.) But then came on the shifting of the current, of which he took advantage, and, aided by the reflux (jusant), laboured with all oars to gain the part of the isle found, in the preceding year, to offer an easy landing. Under these circumstances, the soldiers, with a persevering energy, succeeded, by means of their oars, in giving to the transport ships, in spite of their heaviness, the speed of galleys. The army landed, towards noon, on several points at once,[392] without any appearance of the enemy. Prisoners reported subsequently that the barbarians, terrified at the view of so great a number of ships, had withdrawn to the heights.[393]
