It was what stopped the British led allied bombing which had escalated out of the Blitz. Dresden was not a military target and its destruction killed so many civilians that they stopped night time bombing raids.
No. Dresden was bombed on 15 February 1945 [0]. The British continued night raids until the end of the war, peaking in March, and with the last raid on Berlin on the night of 21/22 April (76 Mosquitos) and the final raid on the night of 25/26 April [1]

Bigger raids happened after Dresden as well and Harris gave his opinion: “I do not personally regard the whole of the remaining cities of Germany as worth the bones of one British Grenadier.” Luckily he alone didn’t make describe I guess.
