The return of the annexed territories to Germany took place on 28 August 1958 due to a German-Belgian border treaty from 24 September 1956. The place Losheimergraben and the western part of the Leykaul municipality, as well as some forests, were excluded from this restoration. These areas remained in Belgium, and so did the previously Belgian municipalities of Eupen and Malmedy that had been incorporated into the German Reich in 1940. [citation needed]
