1864
In March, 1864, with Lieutenant General Ulysses S. Grant now in command of all Union armies, the V Corps was restructured, along with the entire army. The 1st and 2nd Divisions were consolidated into one 1st Division, under General Griffin. Crawford's 3rd Division of Pennsylvanians remained unchanged, although it was due to be mustered out of the service in a few weeks. The I Corps was merged into the V as the 2nd and 4th Divisions, under Generals John C. Robinson and James S. Wadsworth respectively. The new commander of the V Corps was Maj. Gen. Gouverneur K. Warren.
By the time of the Battle of the Wilderness, the corps included over 25,000 men; following the end of the Battle of Spotsylvania Court House in May, 1864, over 10,000 had become casualties. General Wadsworth was killed at the Wilderness, and Robinson was severely wounded (losing a leg) at Spotsylvania. His division was broken down and dispersed temporarily among the others of the V Corps. Wadsworth's Division went under General Lysander Cutler, commander of the Iron Brigade.
The V Corps saw hard fighting at Cold Harbor and the Siege of Petersburg in June. Many of its men were captured in the Second Battle of Weldon Railroad on August 19, 1864. Cutler's division was broken up after these battles. At that point the three remaining divisions were commanded by generals Griffin, Ayres, and Crawford; they would remain until the end of the war. Griffin's division eventually contained most of the remaining regiments of the old V Corps, plus newly organized units. Ayres had new regiments and a few veteran units, including a brigade of Maryland troops. The Regular Division he'd commanded no longer existed as it had been disbanded due to its severe casualties. The remainder of the old I Corps served under Crawford. These divisions participated in the Battle of Peebles' Farm (September 30, 1864).
