First published as To Form a More Perfect Union in 1941, this rare volume of Civil War-era letters relates the poignant experiences of an English immigrant in the service of the United States Army as a noncommissioned officer, civilian employee, and Union volunteer. Frank Clarke served in Mexico, Missouri, New Mexico, and Bleeding Kansas, on the Sioux, Solomon River, and Utah expeditions, and in war-torn Tennessee and Mississippi. After Frank's tragic death in 1862, his wife Mary corresponded with his English mother, detailing the daily struggles of a military widow and her five sons in frontier Kansas. Darlis Miller has kept George Hammond's original annotations and added a few new ones. Her introductions to the book and individual chapters provide biographical details on Frank's and Mary's lives and place their letters in historical context.
