What military successes and defeats did the union experience in 1862?

In the eastern part of the confederacy, the Army of the Protomac met with mixed success. The Union Army failed to capture Richmond and won at Antietam only because the Confederates withdrew from the field first. In the western part of the Confederacy, the Army of the West won the Battle of Shiloh, and the Union navy captured New Orleans and Memphis.
