Four days completed after the arrival of Cæsar in Britain, a tempest dispersed the eighteen ships which, after quitting Ambleteuse, had arrived just within sight of the Roman camp. All the sailors of the Channel who have been consulted believe it possible that the same hurricane, according to the text, might have driven one part of the ships towards the South Foreland and the other part towards the coast of Boulogne and Ambleteuse. The conformation of the ground itself indicates the site of the Roman camp on the height where the village of Walmer rises. It was situated there at a distance of 1,000 or 1,200 mètres from the beach, in a position which commanded the surrounding country. And it is thus easy to understand, from the aspect of the locality, the details relative to the episode of the 7th legion, surprised while it was mowing.[385] It might be objected that at Deal the Roman camp was not near to a water-course, but they could dig wells, which is the only method by which the numerous population of Deal at the present day obtain water.

From all that has just been said, the following facts appear to us to be established in regard to the first expedition. Cæsar, after causing all his flotilla to go out of the port the day before, started in the night between the 24th and 25th of August, towards midnight, from the coast of Boulogne, and arrived opposite Dover towards six o’clock in the morning. He remained at anchor until half-past three in the afternoon, and then, having wind and tide in his favour, he moved a distance of seven miles and arrived near Deal, probably between Deal and Walmer Castle, at half-past four. As in the month of August twilight lasts till after half-past seven, and its effect may be prolonged by the moon, which at that hour was in the middle of the heaven, Cæsar had still four hours left for landing, driving back the Britons, and establishing himself on the British soil. As the sea began to ebb towards half-past five, this explains the anecdote of Cæsius Scæva told by Valerius Maximus; for, towards seven o’clock, the rocks called the Malms might be left uncovered by the ebb of the tide.

After four entire days, reckoned from the moment of landing, that is, on the 30th of August, the tempest arose, and full moon occurred in the following night.

This first expedition, which Cæsar had undertaken too late in the season, and with too few troops, could not lead to great results. He himself declares that he only sought to make an appearance in Britain. In fact, he did not remove from the coast, and he left the island towards the 17th of September, having remained there only twenty-three days.[386]
