Quintus Curtius Rufus, History of Alexander 8.11.13

8.11.13

Et iam eo perventum erat, unde sine pernicie nisi victores redire non possent, ingentia saxa in subeuntes provolventibus barbaris, quis perculsi instabili et lubrico gradu praecipites recidebant.

And now they had attained a point whence they could not return without disaster unless victorious, for as the barbarians rolled down massive stones upon them while they climbed, such as were struck fell headlong from their insecure and slippery positions. Alexander and Charus, however, whom the king had sent in advance with the thirty chosen men, reached the summit, and had by this time engaged in a hand-to-hand fight; but since the barbarians discharged their darts from higher ground, the assailants received more wounds than they inflicted. So then Alexander, mindful alike of his name and his promise, in fighting with more spirit than judgment, fell pierced with many darts. Charus, seeing him lying dead, made a rush upon the enemy, caring for nothing but revenge. Many received their death from his spear and others from his sword. But as he was single-handed against overwhelming odds, he sank lifeless on the body of his friend.
