Not quite glojo. Lord Carrington, the Foreign Secretary resigned in 1982, taking full responsibility for the lack of attention that the FCO had given to the Falklands. John Nott, the Defence Secretary tendered his resignation but it was not accepted. Those were the days when politicians stood up to be counted and took the Mess Webley if needed.
We mustn't forget the Lord Carrington had a distinguished service record in the Second World War, being one of the first to cross Nijmegen bridge as a Sherman tank commander in the Guards during Market Garden. I think he got the MC for that.
