[-41-] Meanwhile Mithridates, named the Pergamenian, undertook to ascend with his ships the mouth of the Nile opposite Pelusium; but when the Egyptians barred his entrance with their boats he betook himself by night to the canal, hauled the ships over into it (it was one that does not open into the sea), and through it sailed up into the Nile. After that he suddenly began from the sea and the river at once a conflict with the vessels that were guarding the mouth and broke up their blockade, whereupon he assaulted Pelusium with both his infantry and his force of ships, and took it. Advancing then to Alexandria he learned that a certain Dioscorides was going to confront them, and he ambushed and annihilated him.
[-42-] The Egyptians on receiving the news would not end the war even under these conditions; yet they were irritated at the sovereignty of the eunuch and the woman and thought if they could put Ptolemy at their head, they would be superior to the Romans. So then, finding themselves unable to seize him by any kind of violence because he was skillfully guarded, they pretended that they were worn out by disasters and desired peace; and they sent to Caesar a herald to ask for Ptolemy, to the end that they might consult with him about the terms on which they would make a truce. Caesar thought that they had in very truth changed front, especially since he heard that they were cowardly and fickle and perceived that at this time they were terrified in the face of their defeats. And in order not to be regarded as hindering peace, even if they were devising some trick, he said that he approved their request, and sent them Ptolemy. He saw no tower of strength in the lad in view of his youth and ignorance, and hoped that the Egyptians would either become reconciled with him on what terms he wished or else would better deserve the waging of war and subjugation, so that there might be some reasonable excuse for delivering them to Cleopatra. He had no idea of being defeated by them, particularly since his force had been augmented. [-43-] The Egyptians, when they secured the child, had not a thought for peace but straightway set out against Mithridates as if they were sure to accomplish some great achievement in the name and by the family of Ptolemy. They cut him off near the lake, between the river and the marshes, and raised a great clamor. Caesar through fear of being ambushed did not pursue them but at night he set sail as if he were hurrying to some outlet of the Nile and kindled an enormous fire on each vessel
