Historical Sketch And Roster Of The Louisiana 21st Infantry Regiment

The Louisiana 21st Infantry Regiment was formed in January, 1862, and mustered into Confederate service in February. Some of the men were recruited in Assumption and St. Helena parishes. The unit was stationed at New Orleans and captured when that city fell in April. After being exchanged, it served in L. Hebert's Brigade, Department of Mississippi and East Louisiana, and was captured again at Vicksburg.

During the Vicksburg siege, the regiment lost 16 killed, 50 wounded, and 1 missing, and after the exchange in December, 1863, only 69 men were present. It was not reorganized. Some of the men served later in the Lousiana 22nd Infantry Regiment Consolidated.
