I don’t they were holding back. Hitler isn’t particularly known for his restraint. It was just more rudimentary technology. There were only around 2000ish planes on either side, and they weren’t committing everything every day. The planes were smaller, the bombs weren’t as destructive, and targeting was pretty basic. They absolutely did tons of damage, but it took months.
Carrying out a similar engagement today would level a city in hours, maybe days.
I have a cool blog I made for class with lots of techy stuff. Can you check it out and tell me what you think?
