Antietam

(an-lie-tăm'.) (Am. Hist.) A creek which, from the S. part of Pennsylvania, where it rises, flows in to Maryland and empties into the Potomac. It gave its name to an obstinately contested battle, fought Sept. 17, 1862, between the National army under Gen. McClellan, and the Confederates under Gen. Lee, in which the former lost 11,426, and the latter 10,000 men. [s. 35]
