In Kassel, the allies dropped 2 bombs per m^2 on average in a couple hours.

I lived in Stuttgart for 10 years (I’m British) and the post-bombing photos of the city filled me with sorrow. 21000 long tonnes dropped on that beautiful provincial city.

Sadly reconstruction was not as kind as it was in Munich (less money presumably).

I love that place and miss it dearly.
