The Kriegsmarine: An Overview

Naval Force of Nazi Germany

The Kriegsmarine served as the navy of Nazi Germany from 1935 to 1945. It succeeded the Imperial German Navy and the inter-war Reichsmarine. As one of the three branches of the Wehrmacht, alongside the Heer (Army) and Luftwaffe (Air Force), it played a significant role in Germany's military strategy during the period.

Treaty Violations and Rearmament

In defiance of the Treaty of Versailles, which imposed severe limitations on Germany's naval capabilities, the Kriegsmarine underwent rapid expansion throughout the 1930s. The treaty prohibited submarines and limited the size and tonnage of other vessels. Germany circumvented these restrictions through clandestine development and construction programs.

Global Reach and Ambitions

The Kriegsmarine's ambitions, particularly under Plan Z, aimed for naval parity with major powers like Great Britain. This involved extensive shipbuilding, including capital ships and a significant submarine fleet. Its operations spanned the Atlantic, Mediterranean, Arctic, and even the Indian Ocean, reflecting Germany's global military objectives.

Historical Trajectory

Spanish Civil War Involvement

The Kriegsmarine's initial military deployment occurred during the Spanish Civil War (1936-1939). Under the guise of enforcing non-intervention, German warships covertly supported the Nationalist faction. This period saw naval engagements and incidents, including the shelling of Almería by the Admiral Scheer in retaliation for an attack on the Deutschland.

Plan Z and WWII Shift

The ambitious Plan Z, initiated in 1939, envisioned a massive fleet by 1945. However, the outbreak of World War II led to its shelving. Resources were redirected towards submarine construction, prioritizing U-boats for the critical Battle of the Atlantic over capital surface warships. This strategic shift defined much of the Kriegsmarine's wartime effort.

Structure and Command

Supreme Command

Adolf Hitler held ultimate authority as Supreme Commander. Operational command was exercised through the Oberkommando der Marine (OKM). Key figures included Commanders-in-Chief Erich Raeder and later Karl Dönitz, who oversaw naval strategy and operations.

Operational Structure

The Kriegsmarine was organized into regional commands (e.g., Nordsee, Norwegen), squadron commands (Battleships, Cruisers, Submarines), and temporary flotilla commands for specific operations. Specialized units like coastal artillery, flak batteries, and naval aviation (though largely under the Luftwaffe) supported its activities.

Ranks and Uniforms

The Kriegsmarine employed a distinct system of ranks and uniforms, reflecting its naval heritage and military structure. Various service, parade, and specialized uniforms were issued, including tropical and summer variants for different operational environments.

Naval Assets

Surface Fleet

The surface fleet comprised battleships (Bismarck-class, Scharnhorst-class), heavy cruisers (Deutschland-class, Admiral Hipper-class), light cruisers, destroyers, torpedo boats, and auxiliary cruisers. Despite significant losses, several major units remained operational until the war's end.

Submarine Force (U-Boote)

The U-boat arm was the Kriegsmarine's most effective weapon, particularly in the Battle of the Atlantic. Types VII and IX were predominant. Despite heavy losses (around 60% of commissioned U-boats), U-boats inflicted significant damage on Allied shipping, with notable aces achieving remarkable success.

Top 10 U-boat Aces in World War II
Name Shipping Sunk
Otto Kretschmer 274,333 tons (47 ships sunk)
Wolfgang Lüth 225,712 tons (43 ships)
Erich Topp 193,684 tons (34 ships)
Karl-Friedrich Merten 186,064 tons (29 ships)
Viktor Schütze 171,164 tons (34 ships)
Herbert Schultze 171,122 tons (26 ships)
Georg Lassen 167,601 tons (28 ships)
Heinrich Lehmann-Willenbrock 166,596 tons (22 ships)
Heinrich Liebe 162,333 tons (30 ships)
Günther Prien 160,939 tons (28 ships), plus HMS Royal Oak

Captured and Auxiliary Vessels

Beyond its purpose-built fleet, the Kriegsmarine utilized numerous captured vessels from occupied nations. Merchant ships were converted into auxiliary cruisers, serving as commerce raiders across the globe. Thousands of smaller craft, including minesweepers and patrol boats, also formed part of its extensive inventory.

Wartime Engagements

Battle of the Atlantic

The Kriegsmarine's primary strategic effort was the Battle of the Atlantic, aimed at disrupting Allied supply lines. U-boats, employing wolfpack tactics, inflicted heavy losses, particularly in the early war years. Allied counter-measures, including improved sonar, radar, and convoy systems, eventually turned the tide.

Global Campaigns

Kriegsmarine operations extended beyond the Atlantic. They participated in the invasion of Norway (Operation Weserübung), engaged in the Mediterranean, and supported campaigns in the Arctic and Black Seas. Surface actions, such as the pursuit of HMS Hood by the Bismarck, marked significant naval encounters.

War Crimes and Accountability

Certain actions undertaken by the Kriegsmarine involved war crimes. These included the targeting of civilian shipping, such as the sinking of the SS Athenia, and documented instances of anti-Jewish measures in occupied territories, such as those ordered in Liepāja. Post-war trials addressed some of these offenses.
