Last weekend, I visited Wurzburg in Germany, which was (and is again) a Baroque jewel, with some 67 magnificent churches within its' boundaries, and was of minimal target value. This was bombed by 5 Group Lancasters on the night of 16 March 1945, and was possibly one of the last major 'city' raids.
There is an information centre close to the old Main bridge, which graphically recalls the raid & subsequent c.2000'c firestorm which consumed some 5,000 civilians & c.90% of the city; the last of the rubble was cleared away in 1964. Wiki has quite a good article on the raid.
The bravery & sacrifice of our Bomber Command crews is without question or stain; we who view these tumultuous events through the safe & comfortable telescope of time have no right to pass judgement on these brave young men, who were fighting for their lives, and, ultimately, ours.
We may, however, question the policies of the day; Harris should have been stopped at the end of 1944. This was a complete failure of the Command chain, right up to & including Churchill. Whilst his earlier BC leadership was exemplary, he eventually was fighting his own private war.
