Operation Happen

This was a British naval undertaking in which Lieutenant J. McQuoid-Masonís MGB-318 of the 15th Motor Gun Boat Flotilla attempted to make a beach reconnaissance near Clogourouan on the Ile de Batz off the north coast of Brittany in the north-western part of German-occupied France, but was defeated by very adverse weather (27/28 September 1943).
