[Graham Boak]

1 out of every 2 bombs did not hit the right country. Only one in five hit a target the size of London. One aircraft lost for every 2 ton of bombs that did hit London, plus whatever accuracy was obtained on the other missions. That's close to one aircraft lost for every two sorties on target.

Whatever the sufferings of Londoners, or indeed Bristolians and others, that's not a successful bombing campaign.
