War Diary and Letters of Stephen Minot Weld.

July 31.— Rode up to headquarters of the Army of the Potomac this morning in an ambulance with the general, Jackson, and Wainwright. About halfway our ambulance broke down, compelling us to seize one belonging to the Sixth Corps, which was passing at the time. We reached headquarters about 3 P.M., having been three or four hours going 10 miles. On the edge of the town of Warrenton we found an immense quartermaster’s establishment, where they were repairing ambulances, shoeing mules and horses, etc. Headquarters were half a mile out from the town, on the Sulphur Springs road. Took lunch with Perkins. Saw Riddle, Oliver, Mitchell, etc. Started to come back on our horses at 6.30 P.M., having passed a very pleasant afternoon. When we arrived at camp, which was at 9 P.M., I found a letter from Father saying that I had been telegraphed for on the 29th instant by General Schouler. Day pleasant.
