Generalfieldmarschall Erwin Rommel, with entourage of senior German military officers, inspects German defenses on the coast of France (so-called "Atlantic Wall"). They tour heavy gun emplacements and shore obstacles. During the tour, they view a large bunker, camouflaged to look like a barn, from the air. Sliding doors are opened revealing a railroad gun. This is a 28cm K5 railway gun of battery E712, at Pointe aux Oies, nearBoulogne-sur-mer, France. Gun crew moves it out, partway on the rails, and raises the barrel to a high elevation. Views of rotating gun turrets; more railway guns, and a 60cm railway mortar called "Thor."
