American troops arrived in France, had heavy weapons in the form of eight-inch howitzers British Mk Mk VII and VIII, which were manufactured in America by the British orders. Having experienced these howitzers in combat, the Americans in the postwar period have decided to adopt a similar artillery systems under the name M1 two calibers: 6.1 inches by 8 inches, which corresponds to the metric system of 155 mm and 203 mm. Both guns were mounted on the same carriages, but smaller caliber gun had a longer barrel and less weight. Compared with the English prototype 8-inch howitzer M1 has been significantly improved: it somewhat lengthened barrel and entered triaxial sprung wheel turn.
