A severe conflict ensued, but Cæsar was victorious. The navy which the Egyptians had so suddenly got together was as suddenly destroyed. Some of the vessels were burned, others sunk, and others captured; and Cæsar returned in triumph to the port with his transports and stores. He was welcomed with the acclamations of his soldiers, and, still more warmly, by the joy and gratitude of Cleopatra, who had been waiting during his absence in great anxiety and suspense to know the result of the expedition, aware as she was that her hero was exposing himself in it to the most imminent personal danger. The arrival of these re-enforcements greatly improved Cæsar's condition, and the circumstance of their coming forced upon the mind of Ganymede a sense of the absolute necessity that he should gain possession of the harbor if he intended to keep Cæsar in check. He accordingly determined to take immediate measures for forming a naval force. He sent along the coast, and ordered every ship and galley that could be found in all the ports to be sent immediately to Alexandria. He employed as many men as possible in and around the city in building more. He unroofed some of the most magnificent edifices to procure timber as a material for making benches and oars. When all was ready, he made a grand attack upon Cæsar in the port, and a terrible contest ensued for the possession of the harbor, the mole, the island, and the citadels and fortresses commanding the entrances from the sea. Cæsar well knew that this contest would be a decisive one in respect to the final result of the war, and he accordingly went forth himself to take an active and personal part in the conflict. He felt doubtless, too, a strong emotion of pride and pleasure in exhibiting his prowess in the sight of Cleopatra, who could watch the progress of the battle from the palace windows, full of excitement at the dangers which he incurred, and of admiration at the feats of strength and valor which he performed. During this battle the life of the great conqueror was several times in the most imminent danger. He wore a habit or mantle of the imperial purple, which made him a conspicuous mark for his enemies; and, of course, wherever he went, in that place was the hottest of the fight. Once, in the midst of a scene of most dreadful confusion and din, he leaped from an overloaded boat into the water and swam for his life, holding his cloak between his teeth and drawing it through the water after him, that it might not fall into the hands of his enemies. He carried, at the same time, as he swam, certain valuable papers which he wished to save, holding them above his head with one hand, while he propelled himself through the water with the other.
