At the Battle of Gaines' Mill in the Seven Days Battles, Slocum's Division was sent to the support of Maj. Gen. Fitz John Porter and became hotly engaged, losing 2,021 men out of less than 8,000 present. The Vermont brigade of Smith's (2nd) Division took a prominent part in the fight at Savage's Station, the 5th Vermont losing 209 men in that action. The corps fought at other points during the Seven Days Battles, but at Malvern Hill it was held in reserve. After the Peninsula Campaign, the VI Corps was recalled to Washington DC and did not participate in the Second Bull Run Campaign aside from the First New Jersey Brigade of Slocum's (1st) Division having a sharp fight on August 27, at Bull Run Bridge, in which it lost 339 in killed, wounded, and missing, Brig. Gen. George W. Taylor, the brigade commander, receiving a mortal wound.
