After rejecting another peace offer from Darius, Alexander set out for Egypt. After several weeks, he took the town and entered Egypt where he established and conquered the city that still bears his name: Alexandria.Alexander faced Darius and his massive troops at Gaugamela in October. Darius fled and was assassinated by his own troops. Finally rid of Darius, Alexander proclaimed himself King of Persia. But another Persian leader, Bessus, had also claimed the Persian throne. Alexander couldn’t let the claim stand.
After relentless pursuit by Alexander, Bessus’s troops handed Bessus over to Ptolemy, Alexander’s good friend, and he was mutilated and executed. With Bessus out of the way, Alexander had full control of Persia. -- -- "http://www.historyofmacedonia.org/AncientMacedonia/images/alexander_athens2.jpg" alt="
