During World War II, Rudolf Sauter was an Army Welfare Officer under South Eastern Command. Although he was never an official war artist he recorded significant events that he witnessed. This watercolours shows so called Spud piers being prepared for the D-Day landings in Normandy. The tall objects like chimneys are the legs that support a landing platform (which could be raised or lowered to suit the tide). Armaments and supplies were landed at these Spud piers and then taken by a floating causeway to the shore.
