After a breakthrough in the German defense lines a large part of France and Belgium were liberated. The general thought was that Holland would be next. However that was not the case, the supply lines for the Allied forces became too long, since the entrance to the Antwerp harbor was still blocked. Both shores of the River Schelcht were still in the hands of the Germans. Moreover, the islands were difficult to approach.
Water is still a mighty force.
Nevertheless,some Allied forces approached the Dutch border and rumors did the rest. German forces withdrew in a panic and were accompanied by their Dutch Nazi friends. The major problem then was the lack of transportation, most of the transportation was controled by the higher German forces and that was all the transportation around. So there was a hunt for transportation. This was a long row of four storey houses.
