Captain (brevet Lt.-Col.) Myles Walter Keogh

Myles Walter Keogh (March 25, 1840 – June 25, 1876) was an Irish soldier. Serving the armies of the Papal States during a rebellion in Italy, he was recruited into the Union Army during the American Civil War, serving as a cavalry officer, particularly under Brig. Gen. John Buford during the Gettysburg Campaign and the three-day battle that ensued. After the war, Keogh remained in the regular United States Army as commander of Company I in the 7th Cavalry Regiment under George Armstrong Custer during the Indian Wars, until he was killed along with Custer and all of his men at the Battle of the Little Bighorn in 1876. http://history1800s.about.com/od/americanoriginals/ig/Custer-and-the-Little-Bighorn/Grave-of-Myles-Keogh.htm
