November 5, 1862: President Lincoln removes General George B. McClellan from command of the Army of the Potomac.  The two men could not stand each other, with McClellan referring to Lincoln as a "great ape", and Lincoln increasingly frustrated with the General's inability to act in the field.  Lincoln said of McClellan: "If General McClellan isn't going to use his army, I'd like to borrow it for a time."
