Confederate Organisations – Armies

Confederate Organisations – Armies

The accumulations of recruits at the start of hostilities were often described as “Lines” or “Forces” or “Army” in a particular area. They might number a few regiments or a few brigades, and all were gradually merged into larger and more permanent formations. These were the nascent formations that developed into Corps and Armies during 1862.

A force might be properly termed an Army if it was operating with a degree of autonomy. An Army could number a few thousand men or tens of thousands of men. They grew and shrank, were formed, disbanded, or merged as operations demanded. An Army commander would lead any number of Brigades and Divisions. From 1862 onwards, most Armies were sub-divided into one or more Corps (more properly termed Army Corps), made up of two or three or more Divisions. In the early days of the war, many Armies were designated although they were small, because they operated autonomously in their area of operations.
