On August 8th, 1918, Allied forces in France launched the Hundred Days Offensive, one of the first combined arms operations of the war that included hundreds of tanks, airplanes, and artillery guns. The offensive was largely a success for the Allies with Germany losing almost 75,000 troops and thousands of machine guns and mortars. The largest prize for the Allies was a massive 28cm German railway gun nicknamed “Bruno”, which had been shelling the French city of Amiens.
