When the battle began, one section (two guns) of Battery E deployed just to the right of the 53rd, which had abandoned its camp and moved into the edge of a treeline facing an open field. The other section remained to the left of the 53rd, as originally deployed. Across this field, Confederates of the 6th Mississippi Infantry and the 23rd Tennessee advanced rapidly toward them. Twelve Confederate guns from Shoup's Arkansas Battery opened up on the Federals, and after firing two rounds in reply, the section that had originally moved to the right was ordered by Sherman's chief of artillery, Major Ezra Taylor, to rejoin the rest of Battery E, on high ground to the left of the 53rd on the other side of Rea Springs and the east fork of Shiloh Branch.
