The Battle of Yorktown (1862) was a battle of the American Civil War that was part of the Union offensive called the Peninsular Campaign. It happened when several regiments under Union Maj. Gen. George McClellan troops met a regiment of the Confederate troops near Yorktown, Virginia along the York River. Considered a skirmish because of the limited number of troops involved, the battle resulted in an estimated 482 causalties. The resulting Union victory allowed the Union forces to continue their advance up the Virginia Peninsula towards Richmond.
