The junction took place without the enemy attempting to hinder it.
Caesar then marched into the Delta, whither the king had retreated,
overthrew, notwithstanding the deeply cut canal in their front,
the Egyptian vanguard at the first onset, and immediately stormed
the Egyptian camp itself. It lay at the foot of a rising ground
between the Nile--from which only a narrow path separated it--
and marshes difficult of access.
Caesar caused the camp to be assailed
simultaneously from the front and from the flank on the path
along the Nile; and during this assault ordered a third detachment
to ascend unseen the heights behind the camp. The victory was complete
the camp was taken, and those of the Egyptians who did not fal
beneath the sword of the enemy were drowned in the attempt to escape
to the fleet on the Nile. With one of the boats, which sank
overladen with men, the young king also disappeared in the waters
of his native stream.
