in 1918 France
This 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 trucks to compose the US Naval Railway Batteries in 1918. In action in Verdun, these guns fired a 1400 pound shell twenty five miles behind the German lines. Aviators did forward reconnaissance and were signaled with cloth panels on the ground the battery was ready to fire .
