German bombers attacked the Firth of Forth near Edinburgh on 16 October 1939. The last raid was a V2 rocket attack near Iwade in Kent on 29 March 1945.
Thanks for the interesting link!
The map seems to be offline right now ‘due to high demand’, but the data can still be accessed. And indicate that the first ‘attack’ actually consisted of two unexploded shells on 6 September 1939. Also, the last raid was actually a V1 according to: https://www.flickr.com/photos/22124479@N03/5001363807
The Wikipedia article on the V1 has Datchworth as its final British target, however. And the dataset lists 7 attacks on that day, apparently listing Datchworth as ‘Batchworth’.
