Alexander at Arbela, Plain of Gaugamela, Iraq, 331BC by David Pentland.  Flanked by his Companion heavy cavalry, Alexander, King of Macedon, led the charge which broke through the left wing of the Persian army, and forced Darius, the Great King, to flee the battlefield.  Persian success against his own left wing forced him to delay his pursuit of the routed troops, but by the end of the day the battle was won, and the heart of the Persian empire lay at his feet.

Alexander the Great crossed the Indus river using makeshift pontoons with 14,000 picked cavalry and infantry. The following day he attacked the flank of King Porus' position, after 8 hours of hard fighting, Alexander the Great's army routed the Indians, taking 9,000 prisoner including King Porus and killing 12,000. The Macedonian army lost 980 men and this was the last battle of the Asian conquest as Alexander's army rebelled and refused to go further.

Porus had a very large army which included 200 war elephants. The battle saw a charge by the elephants, against the Macedonian forces, which began to look successful. Seeing this, Porus' Cavalry charged, against Alexander's cavalry (in this period it was very unusual to have cavalry contact). The elephant charge began to falter and the battle edged towards victory for Alexander. Due to his admiration of Porus as a leader, Alexander granted him honourable terms and built an alliance with him. His army was not so fortunate, with 3,000 cavalry lost and 20,000 infantry killed.
