Density of Bombing - London Region |
 |
|
Both the maps below show Region No. 5, the London Civil Defence Area, during WW2. The one on the left was drawn by me and is divided into the 95 local administrative areas with the number of high explosive bombs that fell per 1,000 acres in each. The one on the right is a heat map of the whole region with the density of HE bombs per square kilometer. If you multiply the figures per kilometer by 4, they are almost exactly the same as those for 1,000 acres. The density map was sourced from Alamy.com (ref. R4kn28), I have purchased a licence to display it here. It was created by the Research and Experimentation department of the Ministry of Home Security in November 1941 as a 'Most Secret' document and was declassified under the 30 year rule on 03/05/1971. It says that the first bombs fell in London Region on 19/06/1940. Under the tape it says 'No bombs have fallen since 27/28 July 1941'. This statement became obsolete in January 1944 when the 'Baby Blitz' began, immediately followed by attacks from V1 flying bombs and V2 rockets. It also says that 'Total number of HE bombs during period covered by this chart 44000. PM are not included in this chart'. PM almost certainly means Parachute Mines. Incendiary bombs are also not included, as there were far too many to count. Click on the map to see a larger version. |
