Pompey fled from Pharsalus to Egypt, where he was assassinated on the order of Pharaoh Ptolemy XIII. Ptolemy XIII sent Pompey's head to Caesar in an effort to win his favor, but Caesar was not pleased with the gift. Pompey was the widower of Caesar's only daughter. Nor did Ptolemy take into account that Caesar was granting amnesty to many of the senators and their men, men who once considered him an enemy.
