History of the Inventory Designer: Skl = Operations Department of the Naval Command Office, Chief of the Authority was Chief of the Staff of the Naval War Command (Skl) from April 1, 1937. In this capacity, in 1938, the former naval intelligence department of the Naval Command Office was subordinated to him. In 1939 the Chief of Staff of the Skl handed over the leadership of the Naval Command Office. In 1939, as a result of the dissolution of the General Naval Office, the Nautical and Military Technical Division joined the Skl. From May 1, 1944, the Chief of the Staff of the Skl was known as the Chief of the Skl. Inventory Description: On April 1, 1937, the Chief of the Naval Command Office was given the additional service designation "Chief of the Staff of the Naval War Command (Skl)". Shortly before the outbreak of war in 1939, the Personalunion chief of the Naval Command Office/Head of the Naval Headquarters Staff was abolished. The Naval Command Office received its own Chief of Staff, who was subordinate to the Chief of Staff of the Skl. From 1.5.1944 the chief of the staff of the Skl led the service designation chief of the naval war management. The naval warfare management was the coordinating and decision-making body for all areas of naval warfare. She was in charge of operational and strategic warfare. It dealt with armaments and personnel matters, tactical problems, questions of ship readiness, equipment and supplies, questions of mine, air and land warfare as well as navigational and meteorological problems. The Skl was divided into the following sections: Chief of the Skl Staff (issued the operational guidelines and orders for the conduct of naval warfare and the deployment of naval forces); Chief of Naval Warfare; Operations Department (dealt with all areas related to the conduct of naval warfare and regulated the deployment of the Navy within the framework of the overall operations and ensured the operational cooperation of the Navy with the army and air force); U-boat department (was responsible for determining the military prerequisites and requirements for submarine construction, the establishment and training of submarine formations and crews, for the creation and design of submarine bases and escort ships as well as the submarine and anti-submarine defence); U-boat command and control department; naval intelligence department / naval intelligence department (was responsible for the entire naval intelligence service, d.h. for the securing of the intelligence connections, for the organisation and deployment of the intelligence service, for radio reconnaissance and radio measurement, as well as for the development, equipment and training of intelligence devices); intelligence evaluation department (collection and evaluation of all intelligence important for naval warfare and the resulting creation of the basis for enemy assessments by the operation group); locating service department (evaluation of operational experience, development, introduction and equipment of locating devices and systems); nautical department (head of the entire hydrographic and meteorological service). Characterisation of the contents: The main part of the tradition from the time after 1933 is the war diary of the Skl with its annexes, which, with a few exceptions, is completely preserved. The war diary records all essential events of the war events, also the land and air war. It also contains political and situation overviews and material on international law, propaganda and merchant shipping. Particularly noteworthy are the documents of the Operations Department and again those of Unit A (Operations of the Naval War, e.g. Case "Weser Exercise", case "Barbarossa", planning "Sea Lion", occupation of Denmark and Norway, attack on the Soviet Union, invasion 1944), of Unit I (International and Naval Law of War), of Unit L (Air Force Issues), of Unit M (work on the Mediterranean theatre of war, Balkans and the Black Sea), N (work on the theatre of war of the Group North, the Norwegian area and the operations spanning the Baltic Sea), and the W (work on the Western area, the Atlantic area and the French coastal forefield). The files of the Operations Department (e.g. case "Weser Exercise", occupation of Denmark) are relatively extensive. The material of the Merchant Shipping and Economic War group as well as of the General Department III (organisational and armament issues) are just as important as the files of the various departments of the Naval Intelligence Service. In addition there is also material about the Japanese Navy, the Spanish Civil War as well as about the cooperation with the Soviet Union, Italy and Spain.
