I did not say they focused on military targets but there were factories that produced for the war. I'm not debating the choice of targets. There were undoubtedly better military target choices.
My point is the factories, the foundries, the ammunition dumps, the logistical hubs, and shipping were not near the target zone. We are talking miles away in the use of a bomb that had minimal affect that far out. We targeted where we did to gauge its affect on a population center, nothing more.
Take a look at a map and pre-bombing photos of that district of the city.
