Commissariat arrangements were generally made by the Persians on a large scale, and with the best possible results. An ample baggage-train conveyed corn sufficient to supply the host during some months and in cases where scarcity was apprehended, further precautions were taken. Ships laden with corn accompanied the expedition as closely as possible, and supplemented any deficiency that might arise from a failure on the part of the land transport department. Sometimes, too, magazines were established at convenient points along the intended line of march previously to the setting forth of the army, and stores were thus accumulated at places where it was probable they would be found of most service.
Requisitions for supplies were also made upon the inhabitants of the towns and villages through which lay the route of the army. Whenever the host rested for a night at a place of any consequence, the inhabitants seem to have been required to furnish sufficient bread for a meal to each man, and, in addition, to provide a banquet for the king (or general) and his suite, which was always very numerous. Such requisitions, often intolerably burthensome to those upon whom they were laid, must have tended greatly to relieve the strain upon their own resources, which the sustentation of such enormous hosts as the Persian kings were in the habit of moving, cannot have failed to produce in many cases.
The effectiveness of these various arrangements for the provisioning of troops upon a march was such that Persian armies were rarely, if ever, in any difficulty with respect to their subsistence. Once only in the entire course of their history do we hear of the Persian forces suffering to any considerable extent from a want of supplies. According to Herodotus, Cambyses, when he invaded Ethiopia, neglected the ordinary precautions and brought his army into such straits that his men began to eat each other. This caused the total failure of his expedition, and the loss of a great proportion of the troops employed in it. There is, however, reason to suspect that, even in this case, the loss and difficulty which occurred have been much exaggerated.
The Persians readily gave quarter to the enemy who asked it, and generally treated their prisoners of war with much kindness. Personages of importance, as monarchs or princes, either preserved their titles and their liberty, with even a certain nominal authority, or received appanages in other parts of the Persian territory, or, finally, were retained about the Court as friends and table-companions of the Great King. Those of less rank were commonly given lands and houses in some province remote from their own country, and thenceforth held the same position as the great mass of the subject races. Exchanges of prisoners do not seem to have been thought of. In a few cases, persons, whom we should regard as prisoners of war, experienced some severities, but probably only when they were viewed by the Persians, not as
