Tuesday, May 10. — Weather pleasant. Heavy firing began on our right, and continued during the day. Regulars were sent to Colonel Humphreys to keep up the communication with General Meade. The 59th and 56th were afterwards ordered there. An attack was made along the whole line about 5 P.M. We gained ground in front of our corps. The firing on Meade’s left surpassed anything I have ever heard. The firing lasted over an hour, but with what success I cannot say. The 56th was afterwards moved over the creek to support a battery. I had my headquarters with them. We all of us felt dreadfully to-day on account of Tom Stevenson’s death. Was with him when he died. Had some of my men make a coffin for him. On the left of the road were three or four terraces, and he was lying down under one of them, when a sharpshooter from Spottsylvania fired at him from one of the trees. The bullet penetrated his head, and he died in half an hour. He will be a sad loss to us all.
