Carlos Alberto César Büsser (10 January 1928 – 29 September 2012) was an Argentine Admiral who commanded Argentine forces during the 1982 invasion of the Falkland Islands who forced the surrender of the Governor of the Falkland Islands, Rex Hunt. He also served as the Chief of the Joint Chiefs of Staff of the Armed Forces of the Argentine Republic.
Following the Argentine defeat in the Falklands War, he was appointed Chairman of the Joint Chiefs of Staff, a position he held until his retirement in 1983. In 1984, Büsser published the book Operación Rosario, a detailed account of the Argentine landings on the Falklands, and, in 1987, Malvinas, la guerra inconclusa, an overall analysis of the conflict.
Büsser died of a heart attack in September 2012. He had been under house arrest since 2009, for alleged human rights abuses committed in the Bahía Blanca area during the 1970s dictatorship.[1] [2]
