The Italian torpedo boats Castore and Montanari firing upon British MTBs and MLs at Tobruk
Operation Agreement was a ground and amphibious operation carried out by British, Rhodesian and New Zealand forces on Axis-held Tobruk from 13 to 14 September 1942, during the Second World War. A Special Interrogation Group party, fluent in German, took part in missions behind enemy lines. Diversionary actions extended to Benghazi (Operation Bigamy), Jalo oasis (Operation Nicety) and Barce (Operation Caravan). The Tobruk raid was an Allied disaster; the British lost several hundred men killed and captured, one cruiser, two destroyers, six motor torpedo boats and dozens of small amphibious craft.
