Their line was broken where it was opposed to Alexander and his immediate companions; but the contagion of disorder rapidly spread, and the whole body of the cavalry shortly quitted the field, after having lost a thousand of their number.
Only the infantry now remained.

Against these the Macedonian phalanx was brought up in front, while the cavalry made repeated charges on either flank with overwhelming effect.

Deserted by their horse, vastly outnumbered, and attacked on all sides, the brave mercenaries stood firm, fought with desperation, and were mostly slaughtered where they stood.

Two thousand out of the 20,000--probably wounded men--were made prisoners.

The rest perished, except a few who lay concealed among the heaps of slain.
The Persians lost by the battle 20,000 of their best footmen, and one or two thousand horse.
