I also asked Halleck to secure the cooperation of the navy in changing our base of supplies from Fredericksburg to Port Royal, on the Rappahannock.
Up to this time I had received no reinforcements, except six thousand raw troops under Brigadier General Robert O.Tyler, just arrived.

They had not yet joined their command, Hancock's corps, but were on our right.

This corps had been brought to the rear of the centre, ready to move in any direction.

Lee, probably suspecting some move on my part, and seeing our right entirely abandoned, moved Ewell's corps about five o'clock in the afternoon, with Early's as a reserve, to attack us in that quarter.

Tyler had come up from Fredericksburg, and had been halted on the road to the right of our line, near Kitching's brigade of Warren's corps.
