The Siege of Alexandria was a series of skirmishes and battles involving the armies of Julius Caesar and his lover Cleopatra against the armies of her brother Ptolemy XIII, backed by the Order of the Ancients in 47 BCE.
After Pompey's armies were defeated by Caesar's forces in their own civil war, his armies were scattered or surrendered to Caesar. Pompey, however, escaped death. While at sea off the Aegean Coast his ship was boarded by Aya of Alexandria to discuss an alliance with Cleopatra, after agreeing he sailed straight for Egypt. He was later killed upon landing in Egypt by Lucius Septimius, a former soldier in his army. The assassination was proposed by the eunuch Pothinus, advisor to the pharaoh Ptolemy XIII who deemed that Caesar would be pleased by the removal of his adversary.
