On 20 December 1940, a landmine flattened my grandmothers house in Copperas Hill. My grandad was away in the army at the time. It also demolished several other houses and a school. I don't know the name of the school, but I think it was a RC primary school. The family was re-housed in 38 Crown Street until 1962.
This is where the internet comes into its own. Years ago, my daughter had to do a project on WW2 and find out if any of her family was affected. I found the number of the German unit in a book, found a list of Luftwaffe units on the internet and saw it was based in Brittany and mostly bombed Liverpool or Bristol. If the weather was bad over one city, it bombed the other. It flew Dornier 17's and when carrying land mines could only manage two because of the weight involved.
