A Lancaster B Mark I (Special) of 617 Squadron releases its 22,000 lb 'Grand Slam' deep penetration bomb over the Arnsberg viaduct in Germany, 19 March 1945. Arnsberg lay in the eastern Ruhr Valley, not far from the Mohne dam, which had been the target for 617’s first operation in 1943. Now, its strategically important railway viaduct was the objective. On 19 March 1945 an attack by 19 Lancasters of 617 Squadron carrying a mixture of 'Tallboy' and 'Grand Slam' bombs brought it crashing down.

'Grand Slam' released over the Arnsberg viaduct

The Bielfeld viaduct, destroyed by the RAF using Grand Slam bombs, 1945.  The damage appears to have been done mainly by direct hits, rather than indirect "earthquake" concussions.  Best regards, JR.
