you are correct in the sense that the USAAF always insisted that there must be a military target as opposed to BC but the fact being neither BC nor USAAF were very accurate so for all intense purposes they both area bombed , Harris IMHO was a jerk who really dragged his feet on the objectives of hitting the Petro industry
I find that hard to understand when BC dropped 93,691 tons while the 8th AF dropped 66,497 tons of bombs on the Petro industry.
