In 1864, the Union and Rebel armies clashed near the Belle Grove mansion during the Battle of Cedar Creek, resulting in more than 8,000 casualties.

The Federals suffered 5,665 casualties (644 killed, 3,430 wounded, and 1,591 missings) out of about 30,000, while Confederate losses were estimated at 2,910 (320 killed, 1,540 wounded, and 1,050 missings) from roughly 18,000. There were about 5,700 Union casualties and 2,900 Confederate casualties. It ranked behind the Third Battle of Winchester as the second bloodiest battle in the Shenandoah Valley.
