remount

Remount referred to the provision of fresh horses, particularly for military purposes. The word encompasses both the animals themselves and the means by which they were provided. In many cases, remounts were horses provided to replace those killed or injured in battle.

The origins of the concept date to the 15th century. Military-based organization of remount programs can be dated to the late 1700s, when both Great Britain and the colonies of what became the United States each created programs for the purchase and training of military animals.
