The Memoirs of General Ulysses S. Grant, Part 5‪.‬

The country about was generally heavily timbered, but with occasional clearings. It was a much better country to conduct a defensive campaign in than an offensive one. By noon of the 9th the position of the two armies was as follows: Lee occupied a semicircle facing north, north west and north east, inclosing the town. Anderson was on his left extending to the Po, Ewell came next, then Early. Warren occupied our right, covering the Brock and other roads converging at Spottsylvania; Sedgwick was to his left and Burnside on our extreme left. Hancock was yet back at Todd's Tavern, but as soon as it was known that Early had left Hancock's front the latter was ordered up to Warren's right. He formed a line with three divisions on the hill overlooking the Po early in the afternoon, and was ordered to cross the Po and get on the enemy's flank.
