In 1940 Sheffield was a city of about 560,000 people and contained many heavy industries, primarily centred around steel and armaments. The Vickers works was host at the time to the only drop hammer in the country, made in Germany by Beche, capable of forging crankshafts for the Rolls Royce Merlin engine which powered the Supermarine Spitfire fighter plane and later in the war the Avro Lancaster bomber. The hammer itself weighed 15 tons and was housed in a 200 ton mounting. It was manned by 16 men working in two shifts. The hammer produced 168 forgings a day which was one of the three operations necessary to make a crankshaft. Hadfields steelworks was also the only place in the UK at that time where 18 inch armour piercing shells were made. Most of the factories were located in the East en

Hadfields steelworks was also the only place in the UK at that time where 18 inch armour piercing shells were made. Most of the factories were located in the East end of the city beside the River Don. Documents captured at the end of the war showed that the targets for the raids included the Atlas Steelworks, Brown Bayley Steelworks, Meadowhall Iron Works, River Don Works, Darnall Wagon Works, Tinsley Park Collieries, East Hecla Works and Orgreave Coke Ovens. The full moon was on 14 December 1940 and both blitz nights were cold and clear. The German code name for the operation was Crucible.
