These are the bridges Sheridan had given orders to his cavalry to occupy
on the 8th, while one division should occupy Spottsylvania. These
movements of the enemy gave me the idea that Lee was about to make the
attempt to get to, or towards, Fredericksburg to cut off my supplies. I
made arrangements to attack his right and get between him and Richmond
if he should try to execute this design. If he had any such intention
it was abandoned as soon as Burnside was established south of the Ny.

The Po and the Ny are narrow little streams, but deep, with abrupt
banks, and bordered by heavily wooded and marshy bottoms--at the time we
were there--and difficult to cross except where bridged. 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. The fourth
division of Hancock's corps, Mott commanding, was left at Todd's when
the corps first came up; but in the afternoon it was brought up and
placed to the left of Sedgwick's--now Wright's--6th corps. In the
morning General Sedgwick had been killed near the right of his
intrenchments by rebel sharpshooters. His loss was a severe one to the
