Couch continued to lead his division during the 1862 Seven Days Battles that followed, fighting in the Battle of Oak Grove on June 25 and the Battle of Malvern Hill on July 1. Later in July Couch's health began to fail, prompting him to offer his resignation. The army commander, Maj. Gen. George B. McClellan, refused to send it to the U.S. War Department, and instead Couch was promoted to major general, to date from July 4. Couch was involved in the Maryland Campaign that fall, although absent from the Battle of Antietam on September 17.
