John E. Wool

John Ellis Wool was an American military officer in the United States Army during three consecutive American-involved wars: the War of 1812 (1812–1815), the Mexican–American War (1846–1848), and with allegiance to the Union in the American Civil War (1861–1865). He also participated in the American Indian Wars and the Trail of Tears, that resulted in Indian tribes being forcefully marched westward in the 1830s from the Southeast US beyond the Mississippi River into the newly established Indian Territory. By the 1840s, he was widely considered one of the most capable officers in the United States Army and an excellent organizer.
