Deane and his fellow Yankees made it work as the 29th Massachusetts and the rest of the brigade fought well together, earning plaudits for hard campaigning during the Seven Days Battles; most notably at Savage's Station, Glendale, and Malvern Hill. After Malvern Hill, Deane, the 29th, and the rest of the brigade remained at Harrison's Landing while other units were transferred to northern Virginia during the summer of 1862 to fight under Gen. John Pope. After Pope was defeated during the Second Battle of Bull Run on August 30, 1862, the 29th Massachusetts joined the Army of the Potomac south of Washington.
