This rare video, produced by the Springfield Arsenal LLC, shows how five 14″ Naval guns — similar to dreadnought turret guns — were made by the Navy, transported to France, and mounted on railway trucks to form the US Naval Railway Batteries in 1918.
In action at Verdun, these guns fired a 1,400-pound shell twenty-five miles behind German lines. Aviators conducted forward reconnaissance and signaled the battery with cloth panels on the ground when it was ready to fire.
