Seven Days Battles (1973)

"It is June 26, 1862. The Army of the Potomac has fought its way nearly 70 miles from the mouth of the York River to a scant dozen miles from the Confederate capitol of Richmond, Virginia. McClellan with his army divided by the rain swollen Chickahominy Creek prepares to assault the city's earthworks. Suddenly, from the north of the Chickahominy, over 50,000 Confederate veterans crash into the Union V Corps. The Battle is joined and the fate of a nation hangs in the balance. Now ... you command the armies! You make the crucial decisions!"
