 After General Robert E. Lee repulsed McClellan's assaults against Richmond, Virginia, what followed was the Seven Days Battles (June 25-July 1, 1862).These battles proved disastrous for the Army of the Potomac, and McClellan refused to take further offensive action from his position at Harrison's Landing without reinforcements.On August 3, 1862, McClellan was ordered by General-in-Chief Henry Halleck to retreat from the peninsula to Aquia Creek and terminate his campaign in order to meet up with the Army of Virginia under General John Pope– an order he only begrudgingly complied with nearly two weeks later.
