From Corporal Keiser’s Diary:

Monday, May 9, 1864.  The Rebels fired a volley into some teams last night.  At 9 a.m. the 5^th Corps took our place and we moved a short distance to the left and took up a line of battle in a woods.  The front line began throwing up rifle pits.  Heard that Gen. Sedgwick our Corps Commander, had been shot in the head by a Rebel sharpshooter, killing him instantly.  He was stationing a battery at the time.  At seven this evening there was hard fighting on our right.  The day was very warm.
