Not only factories, but also methods of transport were targets for the bombers. Britain’s railways, canals and rivers were all used for transport much more in the 1940’s than they are today, and so they, and everything associated with them, became a target. The ship ‘Empire Rancher’ in this picture was built in Knottingley in 1943, and designed to carry coal from South Wales to help fuel war factories in Gloucester. Among the biggest ships built by Harkers Shipyard, she, and other ships made by Harkers, would have made the area a prime target for attack.
