In the east, Union forces could not close on Richmond. General McClellan landed his army on the Lower Peninsula of Virginia. Lee subsequently ended that threat from the east, then Union General John Pope attacked overland from the north only to be repulsed at Second Bull Run (Second Manassas). Lee's strike north was turned back at Antietam MD, then Union Major General Ambrose Burnside's offensive was disastrously ended at Fredericksburg VA in December. Both armies then turned to winter quarters to recruit and train for the coming spring.
