Emory Upton was a United States Army General and military strategist, prominent for his role in leading infantry to attack entrenched positions successfully at the Battle of Spotsylvania Court House during the American Civil War, but he also excelled at artillery and cavalry assignments. His work, The Military Policy of the United States, which analyzed American military policies and practices and presented the first systematic examination of the nation's military history, had a tremendous effect on the U.S. Army when it was published posthumously in 1904.
