Well, don't forget the Dam Busters - two dams destroyed in May 1943 at huge loss of highly trained crews for what , in the final analysis, was a result which fell far short of the 'knock-out blow' which had been hoped for. After the attack, all dams in Germany were surrounded by highly efficient defences.

Even so, 617 Squadron were still attacking dams in September and October 1944 ( the Urft, Kembs and Sorpe Dams ). And despite attacks - in daylight - with Tallboy bombs, the Sorpe never was breached.....

Again, attacks on dams were great in theory but in practice, trying to effectively destroy such a relatively tiny target with 1940s technology was an almost impossible task.

The fact that the Eder and Mohne dams were successfully broken remains one of the greatest feats of air warfare in history - but did it bring Ruhr industry to a halt ? No.... [img]graemlins/no.gif[/img]

The 'foreign investors' theory sounds to me like another of those WWII myths....
