Col. J. Gorgas
Chief of Ordnance Department
 
Colonel,
   Is there a possibility of constructing an iron-plated battery, mounting a heavy gun, on trucks, the whole covered with iron, to move along the {Richmond &} York River Railroad? Please see what can be done. See the Navy Department and officers. If a proper one can be got up at once it will be of immense advantage to us. Have you any mortars that we could put at some point on the railroad?
Very respectfully
R. E. Lee
General
