Quintus Curtius Rufus, History of Alexander 8.14.34

8.14.34

Tum beluam in fugam concitat sequente Alexandro: sed equus eius multis vulneribus confossus deficiensque procubuit posito magis rege quam effuso.

Alexander pursued, but his horse being pierced with many wounds fainted under him, and sank to the ground, laying the king down gently rather than throwing him from his seat. The necessity of changing his horse retarded of course his pursuit. In the meantime the brother of Taxiles, the Indian King whom Alexander had sent on before, advised Porus not to persist in holding out to the last extremity, but to surrender himself to the conqueror. Porus, however, though his strength was exhausted, and his blood nearly spent, yet roused himself at the well-known voice, and said, "I recognise the brother of Taxiles, who gave up his throne and kingdom." Therewith he flung at him the one dart that had not slipped from his grasp, and flung it too with such force that it pierced right through his back to his chest. Having roused himself to this last effort of valour, he began to flee faster than before, but his elephant, which had by this time received many wounds, was now, like himself, quite exhausted, so that he stopped the flight, and made head against the pursuers with his remaining infantry.
