The centre of Vaals borders on Aachen, which is why it took a relatively long time for it to be liberated. The Germans were not prepared under any circumstances to give up the first city on German soil to the rapidly advancing Americans. Hitler had ordered it so.
The surrounding villages and hamlets were liberated between 13 and 17 September 1944, but the centre of Vaals turned into a no man's land and the inhabitants had to exercise patience until 19 October 1944 before they could embrace their liberators. Five endless weeks of nerve-wrecking uncertainty and intense tension had preceded that joyful moment.
