How did Pompey the Great die in Egypt?

After his decisive defeat by Julius Caesar at the Battle of Pharsalus in 48 BCE, Pompey the Great fled to Egypt seeking refuge with the young king Ptolemy XIII, whom he considered a client of the Roman Republic.12

Upon arriving at Pelusium, Pompey was met by a small boat sent by the Egyptian court, which was led by a clique of advisers including Theodotus, Pothinus, and the general Achillas. These advisers had decided that killing Pompey was the best way to curry favor with the victorious Caesar and avoid offending him. As Pompey prepared to step ashore on September 28, 48 BCE, he was treacherously struck down and murdered by his assassins.3245
