Chickahominy (American Civil War).
Fought June 3, 1864, between the Federal Army of the Potomac under Grant, and the Confederate army of Virginia under Lee. Grant attacked the Southerners' entrenchments, with the object of forcing the passage of the Chickahominy, and his first onslaught met with some success, but the Confederates, rallying, drove back their assailants to their original position with heavy loss. All further attempts on Lee's lines failed, and the Federals were finally repulsed with a loss of over 13,000 killed, wounded and missing. The Confederates lost about 6,000.
