GERMAN WARSHIPS, HELIGOLAND
20 Wellingtons were dispatched, 2 as reconnaissance planes and 18 as the bombing force but a recall signal was sent because of fog. 1 Wellington was lost over the sea and 1 crashed in England.
This may have been an experimental raid with the object of finding and bombing German warships by night, to avoid the heavy casualties of recent daylight raids, but the attempt was not repeated.
