Artillery in the early 1900’s were mounted firearms that could shoot a distance of up to 2 km and they could fire 4-6 pound ammunition which was classified as light artillery and the other ammunition was a 8-12 pound shot which was classified as heavy artillery.
Krupp produced a large artillery gun that could fire a 2100 lb shell that could go a distance of 16’000 yards. The gun weighed 175 tons and was transported in five sections to the firing site and assembled there. Because boats and trains could not get everywhere the gun concerned the Germans so they asked for it to be adapted to move on the road to places. In 1914 the new gun made and was named after Krupp’s wife and was called the Big Bertha. The new gun weighed 43 tons and could fire a 2200 lb shell over 9 miles. It was transported by Daimler-Benz tractors and it took a 200 man crew 6 hours to assemble the weapon at the firing site.
