"From June 25 to July 1, 1862, Gen. Robert E. Lee's Army of Northern Virginia engaged Maj. Gen. George B. McClellan's Army of the Potomac in a series of battles at the end of the Peninsula Campaign that would collectively become known as the Seven Days Battles. Beginning with the fighting at the Battle of Beaver Dam Creek, Lee consistently maneuvered against and attacked McClellan's Army of the Potomac as it retreated south across the Virginia Peninsula to the James River. At the conclusion of the Battle of Malvern Hill, Lee's second most costly battle, where McClellan's strong defensive position of infantry and artillery repelled multiple frontal assaults by Lee's troops, the Federal army slipped from Lee's grasp and brought the Seven Days to an end. The Seven Days was a clear Confederate victory that drove the Union army away from the capital at Richmond, began the ascendancy of Robert E. Lee, and commenced a change in the war in the Eastern Theater. It set the stage for the Second Manassas Campaign followed by the Maryland Campaign of 1862"--
