Blacksheep,
The Luftwaffe did not "initiate the black art of strategic bombing in Spain"
The one thing that the Luftwaffe NEVER was in WW2 was a strategic force, it was a highly developed tactical support force. Guernica was an attack on a bridge, Rotterdam was an attack on a town that had been declared a defended fortress by it's defenders.
Coventry was an extremely accurate attack on a city that was unique in it's industrial development, basically you had a medieval town centre that had major industrial development right at it's heart without the usual mix of industrial and residential areas. When the Nov 1940 attack went in, just like the later and much ignored April 1941 attack, the Luftwaffe had individual factories as targets. The technology of the day meant that collateral damage was inevitable. Those individual factories were hit and hit hard, the devastation surrounding them was a consequence not an end in itself.
There is much confusion here between the term "strategic bombing" and "area bombing".
Both the RAF and the USAAF indulged in strategic bombing of German cities. Where they differed is that the USAAF would have a factory or installatio as the aim point whereas the RAF, after 1942, would have an aim point calculated to produce the maximum dehousing and destruction of built up urban areas.
Again, due to the technology of the time, both techniques resulted in devastation of large swathes of urban housing, the difference is that one was deliberate, the other was not.
Harris was not interested in any form of panacea target and even less in individual installations as targets.
He opposed the Dams raid, the formation of the Pathfinders, anything that would distract him from his avowed goal of area bombing of German cities.
The reason there was never a Bomber Command Campaign medal? Look closely at the tactics involved, you would be giving a medal for those that participated in a campaign whose declared target was the German working population of men, women and children.
The 55,000 who died and all those who flew in Bomber Command were brave men and deserve respect and admiration for what they endured. They were not war criminals, neither was Harris, but it would have been a moral disgrace to reward such a campaign with a dedicated medal.
