Caesar's trip into Britain was less an invasion than an expedition. He took only two legions; his cavalry auxiliaries were unable to make the crossing despite several attempts. Caesar crossed late in the season, and in great haste, leaving well after midnight on 23  August. Initially, he planned to land somewhere in Kent, but the British were waiting for him. He moved up the coast and landed—modern archeological finds suggest—at Pegwell Bay,) but the British had kept pace and fielded an impressive force, including cavalry and chariots. The legions were hesitant to go ashore. Eventually, the X legion's standard bearer jumped into the sea and waded to shore. To have the legion's standard fall in combat was the greatest humiliation, and the men disembarked to protect the standard bearer. After some delay, a battle line was finally formed, and the British withdrew. Because the Roman cavalry had not made the crossing, Caesar could not chase down the British. The Roman's luck did not improve, and a Roman supply party was ambushed. The British took this as a sign of Roman weakness and amassed a large force to assault them. A short battle ensued, though Caesar provides no details beyond indicating the Romans prevailed. Again, the lack of cavalry to chase down the fleeing British prevented a decisive victory. The campaigning season was now nearly over, and the legions were in no condition to winter on the coast of Kent. Caesar withdrew back across the Channel.
