1. The Authors that mention this Expedition with any Circumstances, are _Cæsar_ in his _Commentaries_ _lib._ 4, and _Dion Cassius_ in _lib._ 39; _Livy_'s account being lost, in whose 105_th._ Book might possibly have been found the Story more at large. It is certain that this Expedition of _Cæsars_, was in the Year of the _Consulate_ of _Pompey_ and _Crassus_, which was in the Year of _Rome_ 699. or the 55_th_ before the usual Æra of Christ: And as to the time of the Year, _Cæsar_ says that _Exigua parte æstatis reliqua_, he came over only with two Legions, _viz._ the 7_th_ and 10_th_ and all Foot, in about 80 Sail of Merchant Ships, 18 Sail that were ordered to carry the Horse not being able to get out at the same time from another Port, where they lay Wind-bound. He says that he arrived about the 4th hour of the Day, _viz._ between Nine and Ten in the Morning, on the Coast of _Britain_, where he found the Enemy drawn up on the _Cliffs_ ready to repel him, which place he thus describes. _Loci hæc erat natura, adeo montibus augustis mare continebatur ut ex locis superioribus in littus telum adjicit possit_, by which the _Cliffs_ of _Dover_ and the _South Foreland_ are justly described, and could be no other Land, being he says in the 5_th_ Book of his Commentaries, _in Britanniam trajectum esse cognoverit circitur millium passum triginta à continenti_, the _Cliffs_ of the _North-Foreland_ being at a much greater distance. Here he says he came to an Anchor, and staid till the 9_th_ hour, or till about between Three and Four in the Afternoon, expecting till his whole Fleet was come up; and in the mean time called a Council of War, and advertised his Officers, after what manner they were to make their Descent, particularly in relation to the Stuff of the Sea, whose motion he calls _celerem atq. instabilem_, quick and uneven. Then, _viz._ about Three in the Afternoon he weighed Anchor, and having gotten the _Wind_ and _Tide_ with him, he Sail'd about Eight Miles from the first place, and Anchor'd against an open and plain Shore. 2. Here he made his Descent, and having told us the opposition that was made, and the means he used to get on Shore, he comes to say, that after he had been _Four Days_ in _Britain_, the 18 Ships with his Horse put to Sea, and were come in sight of his Camp, when a suddain Tempest arose, with contrary Wind, so that some of the Ships put back again, others were driven to the Westwards, not without great danger, and coming to Anchor, they found they could not ride it out: so when Night came on, they put off to Sea and returned from whence they came. _That same Night_ it was _Full-Moon_, which makes the greatest Tides in the Ocean, and they being ignorant thereof, their Gallies, which were drawn on Shore, were filled by the Tide, _&c._
