War Department renames the forts defending Washington DC to honor senior officers killed in the war
The War Department consolidated the forts defending Washington and at the same time renamed many of them to commemorate senior officers who had died during the war. General Edwin V. Sumner, worn out by Antietam and Fredericksburg, had died at home three months before and Charles F. Smith had died of disease in South Carolina in 1862. All the others honored had been killed in action - Amiel Whipple and Hiram Berry at Chancellorsville, Thomas Williams at Baton Rouge, Joshua W. Sill in Tennessee, and William R. Terrill in Kentucky.
