Alexander determined to set forward immediately in pursuit of Bessus and his prisoner. He did not wait for the return of the foraging parties. He selected the ablest and most active, both of foot soldiers and horsemen, ordered them to take two days' provisions, and then set forth with them that very evening. The party pressed on all that night, and the next day till noon. They halted till evening, and then set forth again. Very early the next morning they arrived at the encampment which the Persian nobleman had described. They found the remains of the camp-fires, and all the marks usually left upon a spot which has been used as the bivouac of an army. The army itself, however, was gone.
