Skill level 2 Although from the mid-19th century, people started considering imparting mobility to large caliber artillery pieces by placing them on special railway mountings, it was WWII that gave the impetus to making the railway gun an important part of many European armories. The German Leopold Gun was the largest weapon, which lobbed shells at American troops at "Anzio Beach". The Leopold was supported by 24 railcar wheels, mounted on railroad tracks, which led in and out of mountain tunnels. When not firing, the gun was rolled back into the tunnels out of sight of Allied reconnaissance. Allied forces were able to salvage the Leopold, and after reconstruction of the railway, moved the gun to Naples for shipment to the States. "Anzio Annie" as the gun was known to Allied troops, is the only German railroad gun known to have survived World War II, and it is currently on display at the Aberdeen Proving Ground in Aberdeen, Maryland.
