During the fighting in Luxembourg in the winter and spring of 1945, the American Graves Registration Service recovered both American and German fallen from the combat zone and buried them in two provisional cemeteries in their rear army area. They are located in the area of two neighboring municipalities; the Germans in Sandweiler and the Americans in Hamm.
In 1952, the government of the Grand Duchy of Luxembourg and the government of the Federal Republic of Germany signed an agreement on the maintenance of German military graves on Luxembourg soil. The old garrison cemetery of the former German federal fortress of Luxembourg is located in Clausen. It is the final resting place of those killed in the 1813 War of Liberation, the 1870–71 Franco-Prussian War, and the years 1817 to 1867, as well as Prussian officers, army officials, and soldiers who died during the garrison period.
During the First and Second World Wars, further fallen soldiers were buried here.
