Valentin Submarine Pens
The Valentin submarine factory is a protective shelter on the Weser River at the Bremen suburb of , built to protect German U-boats during World War II. The factory was under construction from 1943 to March 1945 using forced labour, but was damaged by air-raids and unfinished by the end of the war. The Valentin factory was the largest fortified U-boat facility in Germany, and was second only to those built at Brest in France. As a manufacturing facility, it differed from conventional U-boat pens, which were designed to house and service operational U-boats. Construction Production of U-boats by German shipyards had been dramatically reduced as a result of bombing by the Royal Air Force and the United States Army Air Forces, necessitating the creation of bomb-proof production sites. Many such sites were in use in 1944, including the U-boat pen ''Nordsee III'' on the German island of Helgoland, ''Fink II'' and ''Elbe II'' in Hamburg and ''Kilian'' in Kiel. Other sites in Germany a ...

Third Reich
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of government, ...

Organisation Todt
Organisation Todt (OT; ) was a civil and military engineering organisation in Nazi Germany from 1933 to 1945, named for its founder, Fritz Todt, an engineer and senior Nazi. The organisation was responsible for a huge range of engineering projects both in Nazi Germany and in occupied territories from France to the Soviet Union during World War II. It became notorious for using forced labour. From 1943 until 1945 during the late phase of the Third Reich, OT administered all constructions of concentration camps to supply forced labour to industry. Overview The history of the organisation can be divided into three phases. From 1933 to 1938, before the organisation existed, Fritz Todt's primary post was that of the General Inspector of German Roadways (''Generalinspektor für das deutsche Straßenwesen'') and his primary responsibility, the construction of the ''Autobahn'' network. He was able to draw on "conscripted" (i.e., compulsory) labour, from within Germany, through the Rei ...

Neuengamme Concentration Camp
Neuengamme was a network of Nazi concentration camps in Northern Germany that consisted of the main camp, Neuengamme, and more than 85 satellite camps. Established in 1938 near the village of Neuengamme in the Bergedorf district of Hamburg, the Neuengamme camp became the largest concentration camp in Northwest Germany. Over 100,000 prisoners came through Neuengamme and its subcamps, 24 of which were for women. The verified death toll is 42,900: 14,000 in the main camp, 12,800 in the subcamps, and 16,100 in the death marches and bombings during the final weeks of World War II. Following Germany's defeat in 1945, the British Army used the site as an internment camp for SS and other Nazi officials. In 1948, the British transferred the land to the Free Hanseatic City of Hamburg, which summarily demolished the camp's wooden barracks and built in its stead a prison cell block, converting the former concentration camp site into two state prisons operated by the Hamburg authorities f ...

Albert Speer
Berthold Konrad Hermann Albert Speer (; ; 19 March 1905 – 1 September 1981) was a German architect who served as the Minister of Armaments and War Production in Nazi Germany during most of World War II. A close ally of Adolf Hitler, he was convicted at the Nuremberg trials and sentenced to 20 years in prison. An architect by training, Speer joined the Nazi Party in 1931. His architectural skills made him increasingly prominent within the Party, and he became a member of Hitler's inner circle. Hitler commissioned him to design and construct structures including the Reich Chancellery and the Nazi party rally grounds in Nuremberg. In 1937, Hitler appointed Speer as General Building Inspector for Berlin. In this capacity he was responsible for the Central Department for Resettlement that evicted Jewish tenants from their homes in Berlin. In February 1942, Speer was appointed as Reich Minister of Armaments and War Production. Using misleading statistics, he promoted himsel ...

Submarine Snorkel
A submarine snorkel is a device which allows a submarine to operate submerged while still taking in air from above the surface. British Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers, it was widely used on German U-boats during the last year of World War II and known to them as a ''Schnorchel''. History Until the advent of nuclear power, submarines were designed to operate on the surface most of the time and submerge only for evasion or for daylight attacks. Until the widespread use of radar after 1940, at night a submarine was safer on the surface than submerged, because sonar could detect boats underwater but was almost useless against a surface vessel. However, with continued radar improvement as the war progressed, submarines (notably, the German U-boats in the Battle of the Atlantic) were forced to spend more time underwater, running on electric motors that gave speeds of only a few knots and very limited range. An early submar ...

Periscopes
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an early ...

Bremerhaven
Bremerhaven (, , Low German: ''Bremerhoben'') is a city at the seaport of the Free Hanseatic City of Bremen, a state of the Federal Republic of Germany. It forms a semi-enclave in the state of Lower Saxony and is located at the mouth of the River Weser on its eastern bank, opposite the town of Nordenham. Though a relatively new city, it has a long history as a trade port and today is one of the most important German ports, playing a role in Germany's trade. History in 1827, but neighboring settlements such as Lehe were in the vicinity as early as the 12th century, and Geestendorf was "mentioned in documents of the ninth century". p. 8. Fourth revised edition. Translated into English from the original German edition titled ''Bremerhaven – tätige Stadt im Noordseewind'' These tiny villages were built on small islands in the swampy estuary. In 1381, the city of Bremen established ''de facto'' rule over the lower Weser stream, including Lehe, later therefore called Bremer ...
