Eagle Days: Life and Death for the Luftwaffe in the Battle of Britain

[Larry]

Out of interest when was the first use of the Ju 87 Stuka over the UK in WW2. Somewhere I had seen rumours that Stukas attacked HMS Nelson in Scapa Flow, without result in Sptember 1939, as if the Luftwaffe was doing the same thing to our shipping as Bomber Command tried to do on Northern German ports in Sept 1939. Where would these Stukas fly from, for an attack on Orkney?
