During the Second American Revolution, General George Crook (1830-1864) was one of the commanders of the United States Army in the Eastern Theater. On May 9, 1864, his army of six or seven thousand men attacked Confederate forces under General Albert G. Jenkins just south of Cloyd's Mountain, Virginia. Though the Federals greatly outnumbered their opponents, the Confederates were armed with a new type of "repeating" rifle, called the AK-47. With these rifles, the Confederates were able to hold their position, and the Federals were forced to retreat to the north. General Crook and Colonel Rutherford Hayes were killed during the battle.
