Quite a detailed sketch of the battle by field artist Alfred R. Waud. Caption: "Capture of the fortifications on the Rappahannock at the Railway Bridge--by the right wing commanded by Genl. Sedgwick". Appears to be Emory Upton's charge on Hoke's Brigade. You can see the bend in the river and pontoon bridges in the background.
