African American soldiers played a critical role in the Civil War, and there were men from Maine who worked with "colored troops" in defense against Confederate forces. The military orders shown here relieve two soldiers from duty: Sergeant Fredrick Barnard of Calais, and Private Alexander McFayden of Portland, who returned to the 15th Maine after working alongside the 2nd Engineers, Corps d’Afrique.
Organized at New Orleans, August 15, 1863, the 2nd Engineers, Corps d'Afrique was one of 39 regiments of Black soldiers from Louisiana in the Union Army. Although regiments were segregated, soldiers of different races were stationed in the same areas and sometimes worked together. The 15th Maine was stationed with the Corps d’Afrique on Matagorda Island, Texas. The Corps served garrison at Fort Esperanza and engineer duty on the Matagorda Peninsula.
After Union troops withdrew from the island in May 1864 the 2nd Engineers actively served throughout the Gulf region. They joined the siege against Fort Gaines and Morgan, the campaign against Mobile, Alabama and its Defenses, and the siege of Spanish Fort and Fort Blakely. Only a few days after this order was written, the designation of the 2nd Engineers was changed to the 96th Infantry, US Colored Troops on April 4, 1864.
