Monochrome engraving of the ironclad Rolf Krake (1863). Designed by the naval architect, Cowper Phipps Coles and named after a legendary Danish king, Rolfe Krake was built in Glasgow and commissioned into the Danish Navy in 1864. She saw action in the battle of Dybbol on the 18th of April 1864 during the second war of Schleswig and is seen here in the bay of Vemmingsbund providing heavy artillery cover for the besieged Danish troops on April 1864 under fire from Prussian artillery, with shells landing in the water close to her bow. Smoke issues from her central funnel and two revolving gun turrets are shown to fore and aft. She is schooner rigged with three masts for auxiliary sail propulsion and the Danish flag flies at the stern. The double-spires of Broage Kirke can be seen in the distance. Smoke from the ship's 60- pounder guns can be seen on her starboard side and from the land.
