In 1861 young Joseph Twichell cut short his seminary studies to become a Union Army chaplain in New Yorks Excelsior Brigade. A middle-class New England Protestant, Twichell served for three years in a regiment manned mostly by poor Irish American Catholics. This selection of Twichells letters to his Connecticut family will rank him alongside the Civil Wars most literate and insightful firsthand chroniclers of life on the road, in battle, and in camp. As a noncombatant, he at once observed and participated in the momentous events of the Peninsula and Wilderness Campaigns and at the Second Bull Run, as well as at Fredericksburg, Chancellorsville, Gettysburg, and Spotsylvania.Twichell writes about politics and slavery and the theological and cultural divide between him and his men. Most movingly, he tells of tending the helpless, burying the dead, and counseling the despondent. Alongside accounts of a run-in with slave hunters, a massive withdrawal of wounded soldiers from Richmond, and other extraordinary events, Twichell offers close-up views of his commanding officer, the political general Daniel Sickles, surely one of the most colorful and controversial leaders on either side.Civil War scholars and enthusiasts will welcome this fresh voice from an underrepresented class of soldier, the army chaplain. Readers who know of Twichells later life as a prominent minister and reformer or as Mark Twains closest friend will appreciate these insights into his early, transforming experiences.
