15th Corps Headquarters “Forty Rounds” Flag – American Civil War Nylon Series Reproduction Flag

Historical Background

The 15th Corps Headquarters “Forty Rounds” Flag – American Civil War Nylon Series Reproduction Flag honors one of the most recognizable emblems of Sherman’s Western armies. Formed in December 1862, the XV Corps fought with distinction at Vicksburg, Chattanooga, and throughout the Atlanta and Carolinas Campaigns. Soldiers of this corps adopted the proud motto “Forty Rounds”, a reference to the full cartridge load carried by every Union soldier ready for battle. The phrase came to represent determination, discipline, and relentless fighting spirit across Sherman’s command.

Design Features

This 4′×4′ square headquarters flag features the historic four-quadrant field: red in the upper left, white in the upper right, yellow in the lower left, and blue in the lower right. At its center rests a black cartridge box with a yellow “U.S.” insignia, surrounded by the bold inscription “FORTY ROUNDS.” The quadrants represent the divisions of the corps, while the cartridge box identifies the XV Corps itself. The flag’s design reflected not only the organization of Sherman’s army but also its identity as a hard-fighting, highly mobile force that carried the Union cause deep into Confederate territory.
