I wrote Gen. Halleck,
HAW’S SHOP, VA., May 31, 1864 – 6 a. m.
The enemy came out on our left last evening and attacked. They were easily repulsed and with very considerable slaughter. To relieve General Warren, who was on he left, speedily, General Meade ordered an attack by the balance of our line. General Hancock was the only one who received the order in time to make the attack before dark. He drove the enemy from his entrenched skirmish line and still holds it. I have no report of our losses, but suppose them to be light.
