(2). _First Naval Engagement._—Caesar’s reinforcements had begun to arrive, and a heavy east wind had carried them past the entrance of his harbour. He went out to tow them in, and the Alexandrians issued from their own harbour—the Western—to intercept him. They failed. (3). _Second Naval Engagement and loss of the Island of Pharos._—Issuing from his harbour, Caesar rounded Ras-el-Tin and deployed outside the line of reefs that stretch from it to Agame and guard the entrance to the Western Harbour. The Alexandrians waited inside. Dashing through the entrance he pressed them against the quays of Rhakotis and defeated them. Now he could attack the Island on both sides. On the following day it fell and he made it his headquarters, thus changing the strategy of the war. (4). _Battle of the Dyke._—Caesar now blocked up the arches that penetrated the Heptastadion so that the Alexandrians could not manœuvre from harbour to harbour. Then he tried to force his way into the town. He employed too many troops, and landing in his rear the Alexandrians threw him into confusion. He himself had to jump from the dyke and swim to a boat. Victory. They recaptured the whole of the Heptastadion and reopened its arches. (5). _Battle by the Nile._—The war was after all decided outside Alexandria. More reinforcements were coming to Caesar down the Canopic mouth of the Nile and the Alexandrians marched out to intercept them there. The young Ptolemy XIV was their general now. He was defeated and drowned, his army was destroyed, and Caesar returned in triumph to its city and to Cleopatra. Cleopatra’s fortune now seemed assured. Having married her younger brother (as Ptolemy XV) she went for a trip with Caesar up the Nile to show him its antiquities. The Egyptians detested her as their betrayer but she was indifferent. She bore Caesar a son and followed him to Rome, there to display her insolence. She was at the height of her beauty and power when the blow fell. On the Ides of March, B.C. 44, Caesar was murdered. She had chosen the wrong lover after all.
