Higginson, Thomas Wentworth: Army Life in a Black Regiment. V1. 5 June 2010
 

Thomas Wentworth Higginson (December 22, 1823 – May 9, 1911) was an American minister, author, abolitionist, and soldier. He was active in the American Abolitionism movement during the 1840s and 1850s, identifying himself with disunion and militant abolitionism. During the Civil War, he served as colonel of the 1st South Carolina Volunteers, the first federally authorized African-American regiment, from 1862-1864. Following the war, Higginson devoted much of the rest of his life to fighting for the rights of freed slaves, women and other disenfranchised peoples.

Excerpt
These pages record some of the adventures of the First South Carolina Volunteers, the first slave regiment mustered into the service of the United States during the late civil war. It was, indeed, the first colored regiment of any kind so mustered, except a portion of the troops raised by Major-General Butler at New Orleans. These scarcely belonged to the same class, however, being recruited from the free colored population of that city, a comparatively self-reliant and educated race. "The darkest of them," said General Butler, "were about the complexion of the late Mr. Webster."
