He would not wear such a corslet as had been crushed into his shoulder at Gaza, but put on a breastplate of thick quilted linen, girt with a broad leather belt, guarded with a crust of finely-worked metal, and holding a light, sharp sword.  He had a polished steel helmet, a long spear in his right hand, and a shield on his left arm; and thus he went forth to meet Darius, who came in the midst of 200 chariots, armed with scythes, and fifteen trained elephants.  He had so many troops that he intended to close the wings of his army in upon the Greeks, fold them up, and cut them off; but Alexander, foreseeing this, had warned his men to be ready to face about on any side, and then drew them up in the shape of a wedge, and thus broke into the very heart of the Immortal band, and was on the point of taking Darius prisoner, when he was called off to help Parmenio, whose division had been broken, so that the camp was threatened. Alexander’s presence soon set all right again, and made the victory complete; but Darius had had time to get away, and was galloping on a swift horse to the Armenian mountains.  There was nobody left to defend Assyria, and Alexander marched in through the brazen gates of Babylon, when the streets were strewn with flowers, and presents of lions and leopards borne forth to greet the conqueror.
