Just wanted to pass along a find of mine, for studying during the late 1870's. "The Boy General: Story of the Life of Major-General George A. Custer" written by his wife and Mary Burt in 1901. You can get a super cheap, hardback at amazon:http://www.amazon.com/Boy-General-Major-General-George-Custer/dp/0548977747/ref=reg_hu-wl_item-added
