Amasis II
According to Herodotus, a series of events (which he omits to explain, or does not know for sure) led to Phanes of Halicarnassus falling out of favor with Amasis II. Phanes, disgruntled with the pharaoh deserted Egypt and travelled by ship with the intention of speaking with the Persian emperor Cambyses II. When news reached Amasis II, it caused him great anxiety, leading to him sending his most trustworthy eunuch after Phanes, with the intent of capture or assassination. Phanes originally escaped the assassin, but was eventually captured by him in Lycia. Phanes being of wise mind, however managed to escape by getting the eunuch guards drunk and escaping to Persia. Upon his arrival, he met with a resolute Cambyses II who was about to set out to conquer Egypt but was not sure of the best path possible.
