Confederate Organisations – Departments

Confederate Organisations – Departments

As the Military Division proved to be an impractical level of command for the Confederacy, the highest-level of effective territorial command throughout the war was the Department. Departments reported directly to the President, to the War Department and, eventually but largely theoretically from early in 1865, to the General-in-Chief. Some Departments were subdivided into one or more Districts and Sub-Districts.

Departments were originally created to oversee threatened regions of the Confederate States at the outbreak of the war but eventually extended across the entire Confederacy by the end of the war. As the advancing Union army occupied Confederate territory, many Departments were discontinued or operated with a shadow of the influence their title implied.

The size and borders of Departments and their Districts and Sub-Districts evolved in response to local circumstances and to changing command priorities. Some territorial commands were aligned with state borders, but the majority reflected territories appropriate to military operations, regardless of state and territorial borders.

The nomenclature of territorial command could be inconsistent, and anomalies occasionally arose over the geographical extent and authority of some Departments.
