The Kriegsmarine (German pronunciation: [ˈkʁiːksmaˌʁiːnə], lit. '"War Navy"') was the navy of Nazi Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe of the Wehrmacht, the German armed forces from 1933 to 1945.

In violation of the Treaty of Versailles, the Kriegsmarine grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines.^[2]

Kriegsmarine ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans.

In January 1939, Plan Z was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines (U-boats) instead of capital surface warships and land and air forces were given priority of strategic resources.

The Commander-in-Chief of the Kriegsmarine (as for all branches of armed forces during the period of absolute Nazi power) was Adolf Hitler, who exercised his authority through the Oberkommando der Marine.

The Kriegsmarine's most significant ships were the U-boats, most of which were constructed after Plan Z was abandoned at the beginning of World War II. Wolfpacks were rapidly assembled groups of submarines which attacked British convoys during the first half of the Battle of the Atlantic but this tactic was largely abandoned by May 1943 when U-boat losses mounted. Along with the U-boats, surface commerce raiders (including auxiliary cruisers) were used to disrupt Allied shipping in the early years of the war, the most famous of these being the heavy cruisers Admiral Graf Spee and Admiral Scheer and the battleship Bismarck. However, the adoption of convoy escorts, especially in the Atlantic, greatly reduced the effectiveness of surface commerce raiders against convoys.

Following the end of World War II in 1945, the Kriegsmarine's remaining ships were divided up among the Allied powers and were used for various purposes including minesweeping.

History

Post–World War I origins

Under the terms of the 1919 Treaty of Versailles, Germany was only allowed a minimal navy of 15,000 personnel, six capital ships of no more than 10,000 tons, six cruisers, twelve destroyers, twelve torpedo boats and no submarines or aircraft carriers. Military aircraft were also banned, so Germany could have no naval aviation. Under the treaty Germany could only build new ships to replace old ones. All the ships allowed and personnel were taken over from the Kaiserliche Marine, renamed the Reichsmarine.

From the outset, Germany worked to circumvent the military restrictions of the Treaty of Versailles. Through German-owned front companies, the Germans continued to develop U-boats through a submarine design office in the Netherlands (NV Ingenieurskantoor voor Scheepsbouw) and a torpedo research program in Sweden where the G7e torpedo was developed.^[3]

Even before the Nazi seizure of power on 30 January 1933 the German government decided on 15 November 1932 to launch a prohibited naval re-armament program that included U-boats, airplanes and an aircraft carrier.

The launching of the first pocket battleship, Deutschland in 1931 (as a replacement for the old pre-dreadnought battleship Preussen) was a step in the formation of a modern German fleet. The building of the Deutschland caused consternation among the French and the British as they had expected that the restrictions of the Treaty of Versailles would limit the replacement of the pre-dreadnought battleships to coastal defence ships, suitable only for defensive warfare. By using innovative construction techniques, the Germans had built a heavy ship suitable for offensive warfare on the high seas while still abiding by the letter of the treaty.

Nazi control

When the Nazis came to power in 1933, Adolf Hitler soon began to more brazenly ignore many of the Treaty restrictions and accelerated German naval rearmament. The Anglo-German Naval Agreement of 18 June 1935 allowed Germany to build a navy equivalent to 35% of the British surface ship tonnage and 45% of British submarine tonnage; battleships were to be limited to no more than 35,000 tons. That same year the Reichsmarine was renamed as the Kriegsmarine. In April 1939, as tensions escalated between the United Kingdom and Germany over Poland, Hitler unilaterally rescinded the restrictions of the Anglo-German Naval Agreement.

The building-up of the German fleet in the time period of 1935–1939 was slowed by problems with marshaling enough manpower and material for ship building. This was because of the simultaneous and rapid build-up of the German army and air force which demanded substantial effort and resources. Some projects, like the D-class cruisers and the P-class cruisers, had to be cancelled.

Spanish Civil War

The first military action of the Kriegsmarine came during the Spanish Civil War (1936–1939). Following the outbreak of hostilities in July 1936 several large warships of the German fleet were sent to the region. The heavy cruisers Deutschland and Admiral Scheer, and the light cruiser Köln were the first to be sent in July 1936. These large ships were accompanied by the 2nd Torpedo-boat Flotilla. The German presence was used to covertly support Franco's Nationalists although the immediate involvement of the Deutschland was humanitarian relief operations and evacuating 9,300 refugees, including 4,550 German citizens. Following the brokering of the International Non-Intervention Patrol to enforce an international arms embargo the Kriegsmarine was allotted the patrol area between Cabo de Gata (Almeria) and Cabo de Oropesa. Numerous vessels served as part of these duties including Admiral Graf Spee. On 29 May 1937 the Deutschland was attacked off Ibiza by two bombers from the Republican Air Force. Total casualties from the Republican attack were 31 dead and 110 wounded, 71 seriously, mostly burn victims. In retaliation the Admiral Scheer shelled Almeria on 31 May killing 19–20 civilians, wounding 50 and destroying 35 buildings.^[4] Following further attacks by Republican submarines against the Leipzig off the port of Oran between 15–18 June 1937 Germany withdrew from the Non-Intervention Patrol.

U-boats also participated in covert action against Republican shipping as part of Operation Ursula. At least eight U-boats engaged a small number of targets in the area throughout the conflict. (By comparison the Italian Regia Marina operated 58 submarines in the area as part of the Sottomarini Legionari.)

Plan Z

The Kriegsmarine saw as her main tasks the controlling of the Baltic Sea and winning a war against France in connection with the German army, because France was seen as the most likely enemy in the event of war. But in 1938 Hitler wanted to have the possibility of winning a war against Great Britain at sea in the coming years. Therefore he ordered plans for such a fleet from the Kriegsmarine. From the three proposed plans (X, Y and Z) he approved Plan Z in January 1939. This blueprint for the new German naval construction program envisaged building a navy of approximately 800 ships during the period 1939–1947. Hitler demanded that the program was to be completed by 1945. The main force of Plan Z were six H-class battleships. In the version of Plan Z drawn up in August 1939 the German fleet was planned to consist of the following ships by 1945:

• 4 aircraft carriers
• 10 battleships
• 12 battlecruisers
• 3 armored ships (Panzerschiffe)
• 5 heavy cruisers
• 44 light cruisers
• 158 destroyers and torpedo boats
• 249 submarines
• Numerous smaller craft

Personnel strength was planned to rise to over 200,000.

The planned naval program was not very far advanced by the time World War II began. In 1939 two M-class cruisers and two H-class battleships were laid down and parts for two further H-class battleships and three O-class battlecruisers were in production. The strength of the German fleet at the beginning of the war was not even 20% of Plan Z. On 1 September 1939, the navy still had a total personnel strength of only 78,000, and it was not at all ready for a major role in the war. Because of the long time it would take to get the Plan Z fleet ready for action and shortage in workers and material in wartime, Plan Z was essentially shelved in September 1939 and the resources allocated for its realization were largely redirected to the construction of U-boats, which would be ready for war against the United Kingdom more quickly. ^[5]

World War II

The Kriegsmarine participated in the Battle of Westerplatte and the Battle of the Danzig Bay during the invasion of Poland. In 1939, major events for the Kriegsmarine were the sinking of the British aircraft carrier HMS Courageous and the British battleship HMS Royal Oak and the loss of the Admiral Graf Spee at the Battle of the River Plate. Submarine attacks on Britain's vital maritime supply routes (Battle of the Atlantic) started immediately at the outbreak of war, although they were hampered by the lack of well placed ports from which to operate. Throughout the war the Kriegsmarine was responsible for coastal artillery protecting major ports and important coastal areas. It also operated anti-aircraft batteries protecting major ports.^[6]

In April 1940, the German Navy was heavily involved in the invasion of Norway, where it suffered significant losses, which included the heavy cruiser Blücher sunk by artillery and torpedoes from Norwegian shore batteries at the Oscarsborg Fortress in the Oslofjord. Ten destroyers were lost in the Battles of Narvik (half of German destroyer strength at the time), and two light cruisers, the Königsberg which was bombed and sunk by Royal Navy aircraft in Bergen, and the Karlsruhe which was sunk off the coast of Kristiansand by a British submarine. The Kriegsmarine did in return sink some British warships during this campaign, including the aircraft carrier HMS Glorious.

The losses in the Norwegian Campaign left only a handful of undamaged heavy ships available for the planned, but never executed, invasion of the United Kingdom (Operation Sea Lion) in the summer of 1940. There were serious doubts that the invasion sea routes could have been protected against British naval interference. The Fall of France and the conquest of Norway gave German submarines greatly improved access to British shipping routes in the Atlantic. At first, British convoys lacked escorts that were adequate either in numbers or equipment and, as a result, the submarines had much success for few losses (this period was dubbed the First Happy Time by the Germans).

Italy entered the war in June 1940, and the Battle of the Mediterranean began: from September 1941 to May 1944 some 62 German submarines were transferred there, sneaking past the British naval base at Gibraltar. The Mediterranean submarines sank 24 major Allied warships (including 12 destroyers, 4 cruisers, 2 aircraft carriers and 1 battleship) and 94 merchant ships (449,206 tons of shipping). None of the Mediterranean submarines made it back to their home bases, as they were all either sunk in battle or scuttled by their crews at the end of the war^[7]

The crew of a minesweeper, France, 1941

In 1941 one of the four modern German battleships, Bismarck sank HMS Hood while breaking out into the Atlantic for commerce raiding. Bismarck was in turn hunted down by much superior British forces after being crippled by an air-launched torpedo. She was subsequently scuttled after being rendered a burning wreck by two British battleships.

During 1941, the Kriegsmarine and the United States Navy became de facto belligerents, although war was not formally declared, leading to the sinking of the USS Reuben James. This course of events were the result of the American decision to support Britain with its Lend-Lease program and the subsequent decision to escort Lend-Lease convoys with American war ships through the western part of the Atlantic.

The Japanese attack on Pearl Harbor and the subsequent German declaration of war against the United States in December 1941 led to another phase of the Battle of the Atlantic. In Operation Drumbeat and subsequent operations until August 1942, a large number of Allied merchant ships were sunk by submarines off the American coast as the Americans had not prepared for submarine warfare, despite clear warnings (this was the so-called Second Happy Time for the German Navy). The situation became so serious that military leaders feared for the whole Allied strategy. The vast American ship building capabilities and naval forces were however now brought into the war and soon more than offset any losses inflicted by the German submariners. In 1942, the submarine warfare continued on all fronts, and when German forces in the Soviet Union reached the Black Sea, a few submarines were eventually transferred there.

In February 1942, the three large warships stationed on the Atlantic coast at Brest were evacuated back to German ports for deployment to Norway. The ships had been repeatedly damaged by air attacks by the RAF, the supply ships to support Atlantic sorties had been destroyed by the Royal Navy, and Hitler now felt that Norway was the "zone of destiny" for these ships. The two battleships Scharnhorst and Gneisenau and the heavy cruiser Prinz Eugen passed through the English Channel (Channel Dash) on their way to Norway despite British efforts to stop them.^[8][9][10] Not since the Spanish Armada in 1588 had any warships in wartime done this. It was a tactical victory for the Kriegsmarine and a blow to British morale, but the withdrawal removed the possibility of attacking allied convoys in the Atlantic with heavy surface ships.

With the German attack on the Soviet Union in June 1941 Britain started to send Arctic convoys with military goods around Norway to support their new ally. In 1942 German forces began heavily attacking these convoys, mostly with bombers and U-boats. The big ships of the Kriegsmarine in Norway were seldom involved in these attacks, because of the inferiority of German radar technology,^[11] and because Hitler and the leadership of the Kriegsmarine feared losses of these precious ships. The most effective of these attacks was the near destruction of Convoy PQ 17 in July 1942. Later in the war German attacks on these convoys were mostly reduced to U-boat activities and the mass of the allied freighters reached their destination in Soviet ports.

The Battle of the Barents Sea in December 1942 was an attempt by a German naval surface force to attack an Allied Arctic convoy. However, the advantage was not pressed home and they returned to base. There were serious implications: this failure infuriated Hitler, who nearly enforced a decision to scrap the surface fleet. Instead, resources were diverted to new U-boats, and the surface fleet became a lesser threat to the Allies.

Battleship Tirpitz in Norway, 1944

After December 1943 when Scharnhorst had been sunk in an attack on an Arctic convoy in the Battle of North Cape by HMS Duke of York, most German surface ships in bases at the Atlantic were blockaded in, or close to, their ports as a fleet in being, for fear of losing them in action and to tie up British naval forces. The largest of these ships, the battleship Tirpitz, was stationed in Norway as a threat to Allied shipping and also as a defence against a potential Allied invasion. When she was sunk, after several attempts, by British bombers in November 1944 (Operation Catechism), several British capital ships could be moved to the Far East.

From late 1944 until the end of the war, the surviving surface fleet of the Kriegsmarine (heavy cruisers: Admiral Scheer, Lützow, Admiral Hipper, Prinz Eugen, light cruisers: Nürnberg, Köln, Emden) was heavily engaged in providing artillery support to the retreating German land forces along the Baltic coast and in ferrying civilian refugees to the western Baltic Sea parts of Germany (Mecklenburg, Schleswig-Holstein) in large rescue operations. Large parts of the population of eastern Germany fled the approaching Red Army out of fear for Soviet retaliation (mass rapes, killings and looting by Soviet troops did occur). The Kriegsmarine evacuated two million civilians and troops in the evacuation of East Prussia and Danzig from January to May 1945. It was during this activity that the catastrophic sinking of several large passenger ships occurred: Wilhelm Gustloff and Goya were sunk by Soviet submarines, while Cap Arcona was sunk by British bombers, each sinking claiming thousands of civilian lives. The Kriegsmarine also provided important assistance in the evacuation of the fleeing German civilians of Pomerania and Stettin in March and April 1945.

A desperate measure of the Kriegsmarine to fight the superior strength of the Western Allies from 1944 was the formation of the Kleinkampfverbände (Small Battle Units). These were special naval units with frogmen, manned torpedoes, motorboats laden with explosives and so on. The more effective of these weapons and units were the development and deployment of midget submarines like the Molch and Seehund. In the last stage of the war, the Kriegsmarine also organized a number of divisions of infantry from its personnel.^[6]

Between 1943 and 1945, a group of U-boats known as the Monsun Boats (Monsun Gruppe) operated in the Indian Ocean from Japanese bases in the occupied Dutch East Indies and Malaya. Allied convoys had not yet been organized in those waters, so initially many ships were sunk. However, this situation was soon remedied.^[12] During the later war years, the "Monsun Boats" were also used as a means of exchanging vital war supplies with Japan.

During 1943 and 1944, due to Allied anti-submarine tactics and better equipment the U-boat fleet started to suffer heavy losses. The turning point of the Battle of the Atlantic was during Black May in 1943, when the U-boat fleet started suffering heavy losses and the number of Allied ships sunk started to decrease. Radar, longer range air cover, sonar, improved tactics and new weapons all contributed. German technical developments, such as the Schnorchel, attempted to counter these. Near the end of the war a small number of the new Elektroboot U-boats (XXI and XXIII) became operational, the first submarines designed to operate submerged at all times. The Elektroboote had the potential to negate the Allied technological and tactical advantage, although they were deployed too late to see combat in the war.^[13]

War crimes

Anti-Jewish measures ordered by the German naval commander in Liepāja, 5 July 1941^[14]

Following the capture of the naval base at Liepāja by the Germans on 29 June 1941, Latvia came under the command of the Kriegsmarine. On 1 July 1941, the town commandant Korvettenkapitän Stein ordered that ten hostages be shot for every act of sabotage, and further put civilians in the zone of targeting by declaring that Red Army soldiers were hiding among them in civilian attire.

On 5 July 1941 Korvettenkapitän Brückner, who had taken over for Stein, issued a set of anti-Jewish regulations^[15] in the local newspaper, Kurzemes Vārds.^[14] Summarized these were as follows:^[16]

• All Jews were to wear the yellow star on the front and back of their clothing;
• Shopping hours for Jews were restricted to 10:00 a.m. to 12:00 noon. Jews were only allowed out of their residences for these hours and from 3:00 p.m. to 5:00 p.m.;
• Jews were barred from public events and transportation and were not to walk on the beach;
• Jews were required to leave the pavement if they encountered a German in uniform;
• Jewish shops were required to display the sign "A Jewish-owned business" in the window;
• Jews were to surrender all radios, typewriters, uniforms, arms and means of transportation

On 16 July 1941, Fregattenkapitän Dr. Hans Kawelmacher was appointed the German naval commandant in Liepāja.^[17] On 22 July, Kawelmacher sent a telegram to the German Navy's Baltic Command in Kiel, which stated that he wanted 100 SS and fifty Schutzpolizei (protective police) men sent to Liepāja for "quick implementation Jewish problem".^[18] Kawelmacher hoped to accelerate killings complaining: "Here about 8,000 Jews... with present SS-personnel, this would take one year, which is untenable for [the] pacification of Liepāja."^[19] Kawelmacher on 27 July 1941: "Jewish problem Libau largely solved by execution of about 1,100 male Jews by Riga SS commando on 24 and 25.7."^[18]

In post-war 1945, U-boat Commander Heinz-Wilhelm Eck of U-852 was tried and executed with two of his crewmen for shooting at survivors; likewise U-247 was also involved in shooting at sunken ship survivors, although they were not tried as they were lost at sea.

Post-war division

After the war, the German surface ships that remained afloat (only the cruisers Prinz Eugen and Nürnberg, and a dozen destroyers were operational) were divided among the victors by theTripartite Naval Commission. The US used the heavy cruiser Prinz Eugen in nuclear testing at Bikini Atoll in 1946 as target ship. Some (like the unfinished aircraft carrier Graf Zeppelin) were used for target practice with conventional weapons, while others (mostly destroyers and torpedo boats) were put into the service of Allied navies that lacked surface ships after the war. The training barque SSS Horst Wessel was recommissioned USCGC Eagle and remains in active service, assigned to the United States Coast Guard Academy. The British, French and Soviet navies received the destroyers, and some torpedo boats went to the Danish and Norwegian navies. For the purpose of mine clearing, the Royal Navy employed German crews and minesweepers from June 1945 to January 1948,^[20] organized in the German Mine Sweeping Administration, the GMSA, which consisted of 27,000 members of the former Kriegsmarine and 300 vessels.^[21]

The destroyers and the Soviet share light cruiser Nürnberg were all retired by the end of the 1950s, but five escort destroyers were returned from the French to the new West German navy in the 1950s and three 1945 scuttled type XXI and XXIII U-boats were raised by West Germany and integrated into their new navy. In 1956, with West Germany's accession to NATO, a new navy was established and was referred to as the Bundesmarine (Federal Navy). Some Kriegsmarine commanders like Erich Topp and Otto Kretschmer went on to serve in the Bundesmarine. In East Germany the Volksmarine (People's Navy) was established in 1956. With the reunification of Germany in 1990, it was decided to use the name Deutsche Marine (German Navy).

Ships

R boats operating near the coast of occupied France, 1941

By the start of World War II, much of the Kriegsmarine were modern ships: fast, well-armed and well-armoured. This had been achieved by concealment but also by deliberately flouting World War I peace terms and those of various naval treaties. However, the war started with the German Navy still at a distinct disadvantage in terms of sheer size with what were expected to be its primary adversaries – the navies of France and Great Britain. Although a major re-armament of the navy (Plan Z) was planned, and initially begun, the start of the war in 1939 meant that the vast amounts of material required for the project were diverted to other areas. The sheer disparity in size when compared to the other European powers navies prompted German naval commander in chief Grand Admiral Erich Raeder to write of his own navy once the war began "The surface forces can do no more than show that they know how to die gallantly." A number of captured ships from occupied countries were added to the German fleet as the war progressed.^[22] Though six major units of the Kriegsmarine were sunk during the war (both Bismarck-class battleships and both Scharnhorst-class battleships, as well as two heavy cruisers), there were still many ships afloat (including four heavy cruisers and four light cruisers) as late as March 1945.

Some ship types do not fit clearly into the commonly used ship classifications. Where there is argument, this has been noted.

Surface ships

The main combat ships of the Kriegsmarine (excluding U-boats):

Aircraft carriers

Construction of the Graf Zeppelin was started in 1936 and construction of an unnamed sister ship was started two years later in 1938, but neither ship was completed. In 1942 conversion of three German passenger ships (Europa, Potsdam, Gneisenau) and two unfinished cruisers, the captured French light cruiser De Grasse and the German heavy cruiser Seydlitz, to auxiliary carriers was begun. In November 1942 the conversion of the passenger ships was stopped because these ships were now seen as too slow for operations with the fleet. But conversion of one of these ships, the Potsdam, to a training carrier was begun instead. In February 1943 all the work on carriers was halted because of the German failure during the Battle of the Barents Sea which convinced Hitler that big warships were useless.

All engineering of the aircraft carriers like catapults, arresting gears and so on were tested and developed at the Erprobungsstelle See Travemünde (Experimental Place Sea in Travemünde) including the airplanes for the aircraft carriers, the Fieseler Fi 167 ship-borne biplane torpedo and reconnaissance bomber and the navalized versions of two key early war Luftwaffe aircraft: the Messerschmitt Bf 109T fighter and <a href="htt
