During World War I, Antwerp became the fallback point of the Belgian Army after the defeat at the Battle of Liège. The Siege of Antwerp lasted for 11 days, the city was taken by the German Army after heavy fighting, and the Belgians were forced to retreat westwards. Fort 8, one of the forts defending Antwerp located in the south of Hoboken, was of not much use during WWI, it was built in 1864 and was terribly outdated. Antwerp remained under German control until the Armistice of 11 November 1918.
