It was obeyed Operation Basalt was carried out by British commandos on the island of Sark on the night of 3/4 October 1942, intended to serve several purposes. The raid itself was a tactical success: a German prisoner was captured, several more were killed, and all British soldiers returned safely to base. It is remembered because of Hitler's reaction. He ordered: 'In future, all terror and sabotage troops of the British … will be ruthlessly eliminated in battle.'
