Anzio Annie, Anzio Express, "Leopold"; known by many names, the German 8 cm Kanone 5 Eisenbahngeschütz (railway gun), commonly abbreviated K5(E), was the most successful and widely used of Germany's railway gun designs. Twenty-four of the weapons, capable of shelling England from positions in France, were built and were used by Germany on most of their fronts, including France, Italy, Russia, and Holland. The operation and use of these fearsome weapons are presented through 80 period black-and-white photos. The vintage photos are supplemented by over 150 full-color photos of the only surviving examples, illustrating the nuances of the construction of these massive weapons.
