On the night of Nov. 5-6, 1941, Yeates took Lockheed Hudson V (AM 642 "“ R Robert) into the air from RAF Thornaby, in North Yorkshire, and headed for a general North Sea line between Terschelling (Frisian Islands) and the Heligoland Bight. The idea was to patrol and attack anything found.
The strike was led by Wing Commander Rupert Derbyshire, who had eight Hudsons on the operation. It turned out to be a busy, costly evening.
O Orange flew right by a Luftwaffe Me 110, and probably a JU 88, without being seen, then attacked a convoy and likely overshot with its bombs. G George found the same convoy, hit something and caused a fire, without definite results. L Lion surprised a flak ship (which must have scared hell out of the crew as well), dropped its bombs, and came home with a six-inch hole in the starboard wing.
H Harry dropped on a merchant vessel of some description, "starting a fire."
Nothing was ever heard again from the wing commander and his crew, or Gordon Yeates and his (Sgt. J. Sansome, Sgt. Francis J. Hazlett, Sgt, Eric Elkington). They disappeared into the North Sea and are remembered on the Runnymede Memorial, north west of London.
