SMS Gneisenau
"Gneisenau" was laid down at the AG Weser shipyard in Bremen, Germany in 1904, under construction number 144. She was launched on 14 June 1906, and commissioned into the fleet nearly two years later on 6 March 1908. The ship cost the German government 19,243,000 goldmarks. The ship had been designed for service with the High Seas Fleet, though it was found to be too weak for service with the battle fleet; instead it was deployed overseas, a role in which it performed well.
SMS Arminius
SMS "Arminius"  was an ironclad warship of the Prussian Navy, later the Imperial German Navy. The ship was designed by the British Royal Navy Captain Cowper Coles and built by the Samuda Brothers shipyard in Cubitt Town, London as a speculative effort; Prussia purchased the ship during the Second Schleswig War against Denmark, though the vessel was not delivered until after the war. The ship was armed with four guns in a pair of revolving gun turrets amidships. She was named for Arminius, the victor of the Battle of the Teutoburg Forest.
