<P> Alexander commenced the battle by sending his Scythian hired horse archers to shower the Indian right cavalry wing . His armored Companion Cavalry was sent to the outnumbered Indian left cavalry with him leading the charge himself . The rest of the Indian cavalry galloped to their hard pressed kinsmen on the right wing but at this moment, Coenus's cavalry contingent appeared on the Indian rear . The Indians tried to form a double phalanx, but the necessary complicated maneuvers brought even more confusion into their ranks making it easier for the Macedonian horse to conquer . </P> <P> Alexander, destroying Porus' right flank circled around to Porus' left flank launching a mass attack against Porus's left flank . Alexander surmised correctly that Porus would be forced to move cavalry on the right wing across to the left . Alexander foresaw this and placed his cavalry, under the command of Coenus, opposite of them and out of sight . Their job was to break cover and follow the Indian cavalry, which forced the Indians to go forward, right into Craterus . Arrian states that 12,000 Indians and 80 elephants died in this mass pincer movement . </P> <P> Porus, atop his elephant, personally led his elephant corps instead of the usual double - horse chariot used by Indian kings . The War - Elephants caused heavy losses to the phalanx, impaling many with their tusks fitted with steel spikes and heaving some before pulverizing them . Alexander commanded his Indian Contingents to end the carnage, with the light infantry which tossed javelins at the Elephants' eyes while the heavy infantry ham - stringed the Elephants with the two - sided axes and scimitars . They were eventually repulsed by the dense pikes of the phallangitai, wreaking much havoc upon their own lines . The mahouts were killed before they could kill their panicked elephants with poisoned rods . The remaining Indian cavalry fled among the elephants for protection, but the beasts were already out of control and would soon retreat exhausted from the field, leaving the rest of Porus's army encircled by the Macedonian horse and phalanx . Alexander sent his phalanx to attack the elephants, which were forced back on their own side . They boxed the Indian infantry and cavalry, many of whom were trampled to death . At this time, the phallangitai locked their shields and advanced upon the confused enemy . By this time Craterus and his force in the base camp crossed the river when the way was clear, and they conducted a chase against those who retreated . </P> <P> Arrian records that in the final charge against Alexander, King Porus employed all his cavalry, 4,000 strong, all his remaining chariots, 300 in number, 200 of his elephants, and 30,000 of efficient infantry along with 2,000 men and 120 chariots detached earlier in the day under his son's charge . </P>
