Bombing of Sheffield
During the night of 12 December 1940 German planes flew over Sheffield, a city in South Yorkshire, and began dropping bombs. For hours, the city was under enemy fire. In terms of actual attacks in Sheffield, there had been very few and far between and the residents of Sheffield had become quite blase when the air sirens went off, people didn't really bat an eyelid because it had happened so many times and there hadn't been any serious bombings.
Sadly that all changed. Around seven o'clock the air raids sirens went and it was followed by something that had rarely been heard which was the sound of their own anti-aircraft fire.
This attack destroyed a great deal of the city and surrounding suburbs.
