the codename for the invasion of the Dutch Island of Walcheren, was a major Combined Operation’s amphibious landing against entrenched German defensive positions. The fortified island stood at the mouth of the River Scheldt blocking Allied access to the captured port of Antwerp some 60 kilometres inland. It was urgently needed to supply the advancing Allied armies as they moved towards Berlin.
