Crassus

After furnishing the cities which had come over to his side with garrisons, which amounted in all to seven thousand men-at-arms and a thousand horsemen, he himself withdrew to take up winter quarters in Syria, and to await there his son, who was coming from Caesar in Gaul, decorated with the insignia of his deeds of valour, and leading a thousand picked horsemen. This was thought to be the first blunder which Crassus committed,—after the expedition itself, which was the greatest of all his blunders,—because, when he should have advanced and come into touch with Babylon and Seleucia, cities always hostile to the Parthians, he gave his enemies time for preparation.

Then, again, fault was found with him because his sojourn in Syria was devoted to mercenary rather than military purposes. For he made no estimate of the number of his troops, and instituted no athletic contests for them, but reckoned up the revenues of cities, and spent many days weighing exactly the treasures of the goddess in Hierapolis, and prescribed quotas of soldiers for districts and dynasts to furnish, only to remit the prescription when money was offered him, thereby losing their respect and winning their contempt.
