Confederate Picture of the Day: After Fredericksburg, on the Rappahannock River

After the Battle of Fredericksburg, the Southern and Northern armies were separated from each other, on opposite sides of the Rappahannock river.  Some Northern photographer took a photo of Confederate soldiers on the other side.  The uniforms of the Confederates is very interesting -- basically, gray uniforms, shell jackets (short jackets that reach to the waist) with black slouch hats.  I have blown up the photo to see the soldiers better.  There is one soldier, probably an officer, wearing a frock coat (long, reaches to mid-thigh) with a double-row of buttons.
