Issus (Alexander's Asiatic Campaigns).
Fought B.C. 333, between 35,000 Macedonians, under Alexander the Great, and a vast horde of Asiatics, with 30,000 Greek mercenaries, under Darius, King of Persia. The Persians were drawn up on the right bank of the Pinarus, which crosses the plain of Issus. Alexander, led his heavy cavalry to the attack on the left, crossing the river, and routing the Persian cavalry. The phalanx in the centre was opposed to the Greek mercenaries, and after heavy fighting, the Macedonians made good their footing on the right bank. Alexander meanwhile led his squadrons against the bodyguard of Darius, who fled from the field, followed by the whole of the Asiatics, and the victory was complete.
