The German auxiliary cruiser Atlantis, known to the Kriegsmarine as Schiff 16 and to the Royal Navy as Raider-C, was a converted German Hilfskreuzer, or merchant or commerce raider of the Kriegsmarine, which, in World War II, travelled more than 161,000 km (100,000 mi) in 602 days, and sank or captured 22 ships with a combined tonnage of 144,384. Atlantis was commanded by Kapitän zur See Bernhard Rogge, who received the Oak Leaves to the Knight's Cross of the Iron Cross. She was sunk on 22 November 1941 by the British cruiser HMS Devonshire.
Merchant raiders are armed commerce raiding ships that disguise themselves as non-combatant merchant vessels.
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade.
SS Alcantara was an ocean liner which entered service just weeks before the start of World War I, was converted to an armed merchant cruiser in 1915, and was sunk in combat with the German armed merchant cruiser SMS Greif in the Action of 29 February 1916.
Widder was an auxiliary cruiser (Hilfskreuzer) of Nazi Germany's Kriegsmarine that was used as a merchant raider in the Second World War. Her Kriegsmarine designation was Schiff 21, to the Royal Navy she was Raider D. The name Widder (Ram) represents the constellation Aries in German.
SS Kronprinz Wilhelm was a German passenger liner built for the Norddeutscher Lloyd, a former shipping company now part of Hapag-Lloyd, by the AG Vulcan shipyard in Stettin, Germany, in 1901. She took her name from Crown Prince Wilhelm, son of the German Emperor Wilhelm II, and was a sister ship of SS Kaiser Wilhelm der Grosse.
SS Cap Trafalgar was a German ocean liner launched in 1913 for the Hamburg Süd line. In 1914, she was converted for use as an auxiliary cruiser during World War I. She was the first armed merchant cruiser sunk by a ship of the same class; she was destroyed by HMS Carmania, also a converted ocean liner, in a furious action in the South Atlantic in September 1914. It was the world's first battle between former ocean liners.
SMS Möwe was a merchant raider of the Imperial German Navy which operated against Allied shipping during World War I.
HMS Achilles was a Warrior-class armoured cruiser built for the Royal Navy in the first decade of the 20th century. She served with the 2nd Cruiser Squadron for most of the First World War. The ship did not participate in the Battle of Jutland in 1916, but did sink the German raider Leopard in 1917. Achilles became a training ship in 1918 and was sold for scrap in 1921.
HMS King Alfred was one of four Drake-class armoured cruisers built for the Royal Navy around 1900. She served as flagship of the China Station from 1906 until relieved in 1910. Upon her return home that year, she was placed in reserve before being recommissioned in mid-1914. She was assigned to the 6th Cruiser Squadron of the Grand Fleet at the beginning of World War I. She was transferred to the 9th Cruiser Squadron in 1915 and assigned to convoy protection duties by the end of the year. King Alfred participated in the unsuccessful searches for the German commerce raider SMS Möwe in 1916–17 before beginning to escort convoys later that year. The ship was torpedoed by a German submarine in 1918, but returned to service. She was sold for scrap in 1920.
The Action of 16 March 1917 was a naval engagement in which the British armed boarding steamer SS Dundee and HMS Achilles, a Warrior-class armoured cruiser, fought the German auxiliary cruiser SMS Leopard, which sank with the loss of all 319 hands and six men of a British boarding party.
SS Dundee was a British steamship that was built in Scotland in 1911 and sunk by enemy action in the Celtic Sea in 1917. She was designed as a coastal passenger and cargo liner for the Dundee, Perth & London Shipping Company Ltd, but in 1915 she was converted into an armed boarding steamer for the Royal Navy. She took part in the Action of 16 March 1917, was sunk by a U-boat six months later, and lost members of her crew in both actions.
SMS Greif was a German cargo steamship that was converted into a merchant raider for the Imperial German Navy.
The action of 10 March 1917 was a single-ship action in the First World War between the Imperial German Navy merchant raider SMS Möwe and the defensively-armed New Zealand Shipping Company cargo ship Otaki. Otaki was sunk, but Möwe was badly damaged.
SMS Meteor was an auxiliary cruiser of the Imperial German Navy which operated against Allied shipping during World War I.
The German commerce raiders of World War I were surface vessels used by the Imperial German Navy for its Handelskrieg, a campaign against Allied seaborne trade. The ships comprised warships, principally cruisers, stationed in the German colonial empire before the war began, express liners commissioned as auxiliary cruisers and later, freighters outfitted as merchant raiders. These vessels had a number of successes and had a significant effect on Allied naval strategy, particularly in the early months of the war.
The Type 23 torpedo boat was a group of six torpedo boats built for the Reichsmarine during the 1920s. As part of the renamed Kriegsmarine, the boats made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, they played a minor role in the Norwegian Campaign of 1940, Albatros being lost when she ran aground. The Type 23s spent the next several months escorting minelayers as they laid minefields and escorting ships before the ships were transferred to France around September. Möwe was torpedoed during this time and did not return to service until 1942. They started laying minefields themselves in September and continued to do so for the rest of the war.
Kondor was the fifth of six Type 23 torpedo boats built for the German Navy. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she played a minor role in the attack on Oslo, the capital of Norway, during the Norwegian Campaign of 1940. Kondor spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September. She started laying minefields herself that month and continued to do so for the rest of the war. The boat returned to France in 1942 and helped to escort blockade runners, commerce raiders and submarines through the English Channel and the Bay of Biscay. Damaged by a mine shortly before the Allied Invasion of Normandy in June 1944, Kondor was under repair on the day of the landings. Recognizing that she could not be repaired quickly, the boat was decommissioned later that month and was then further damaged by British bombers so that she was declared a constructive total loss.
Falke was the sixth and last Type 23 torpedo boat built for the German Navy. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she played a minor role in the Norwegian Campaign of 1940. Falke spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September. She started laying minefields herself that month and continued to do so for the rest of the war. After a refit in early 1941, the boat was transferred to the Skaggerak where she was assigned escort duties. Falke returned to France in 1942 and was one of the escorts for the capital ships sailing from France to Germany through the English Channel in the Channel Dash. She helped to escort blockade runners, commerce raiders and submarines through the Channel and the Bay of Biscay for the next several years. The boat attacked Allied ships during the Invasion of Normandy in June 1944, but was sunk by British bombers that same month.
Möwe was the lead ship of the her class of six torpedo boats built for the German Navy. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During the Norwegian Campaign of 1940, she played a minor in the attack on Oslo, the capital of Norway. Möwe was torpedoed and badly damaged by a British submarine in May and did not return to active service until 1942 when she was transferred to France. The boat helped to escort blockade runners, commerce raiders and submarines through the Bay of Biscay. She also laid numerous minefields and attacked Allied ships during the Invasion of Normandy in June 1944. Möwe was sunk by British bombers that same month.
