While halting for these foraging parties to return, a Persian nobleman came into the camp, and informed Alexander that Darius and the forces accompanying him were encamped about two days' march in advance, but that Bessus was in command—the conspiracy having been successful, and Darius having been deposed and made a prisoner. The Greeks, who had adhered to their fidelity, finding that all the army were combined against them, and that they were not strong enough to resist, had abandoned the Persian camp, and had retired to the mountains, where they were awaiting the result.

The pursuit continued.

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.

Alexander stops to rest his army.

The pursuers were now too much fatigued to go any further without rest. Alexander remained here, accordingly, through the day, to give his men and his horses refreshment and repose. That night they set forward again, and the next day at noon they arrived at another encampment of the Persians, which they had left scarcely twenty-four hours before. The officers of Alexander's army were excited and animated in the highest degree, as they found themselves thus drawing so near to the great object of their pursuit. They were ready for any exertions, any privation and fatigue, any measures, however extraordinary, to accomplish their end.

Want of water.
Disregarded by Alexander.
The pursuit grows more exciting.

Alexander inquired of the inhabitants of the place whether there were not some shorter road than the one along which the enemy were moving. There was one cross-road, but it led through a desolate and desert tract of land, destitute of water. In the march of an army, as the men are always heavily loaded with arms and provisions, and water can not be carried, it is always considered essential to choose routes which will furnish supplies of water by the way. Alexander, however, disregarded this consideration here, and prepared at once to push into the cross-road with a small detachment. He had been now two years advancing from Macedon into the heart of Asia, always in quest of Darius as his great opponent and enemy. He had conquered his armies, taken his cities, plundered his palaces, and made himself master of his whole realm. Still, so long as Darius himself remained at liberty and in the field, no victories could be considered as complete. To capture Darius himself would be the last and crowning act of his conquest. He had now been pursuing him for eighteen hundred miles, advancing slowly from province to province, and from kingdom to kingdom. During all this time the strength of his flying foe had been wasting away. His armies had been broken up, his courage and hope had gradually failed, while the animation and hope of the pursuer had been gathering fresh and increasing strength from his successes, and were excited to wild enthusiasm now, as the hour for the final consummation of all his desires seemed to be drawing nigh.

Guides employed.

Guides were ordered to be furnished by the inhabitants, to show the detachment the way across the solitary and desert country. The detachment was to consist of horsemen entirely, that they might advance with the utmost celerity. To get as efficient a corps as possible, Alexander dismounted five hundred of the cavalry, and gave their horses to five hundred men—officers and others—selected for their strength and courage from among the foot soldiers. All were ambitious of being designated for this service. Besides the honor of being so selected, there was an intense excitement, as usual toward the close of a chase, to arrive at the end.

The Persians overtaken.
