Carl von Horn (1903–1989)

In early 1958, von Horn was appointed chief of United Nations Truce Supervision Organization in Palestine by Dag Hammarskjöld, and was then promoted to major general. At first he allowed himself "to be optimistic" and he wrote in his memoirs that "instead of fully armed troops, tanks and artillery or even the threat of sanctions, Dag's moral support and my own determination was everything I had." In 1960 he became with short notice the Supreme Commander of the UN Force in the Congo during the beginning of what was to develop into the Congo Crisis, a mission, however, he was dismissed from six months later. von Horn then returned to work for the UN in Palestine. In 1963 he was sent to lead the UN observatory group United Nations Yemen Observation Mission in Yemen where fighting continued between government troops and rebels.

During World War II he helped organizing prisoner exchange between the Germans and the Allies, but also had to work with the Swedish extradition of Baltic soldiers. As a military man with a strong Anglo-Saxon ethos he called this "the most humiliating moment in modern Swedish history." von Horn was promoted to lieutenant colonel in 1945 when he also became chief of the Defence Staff's Communication Department. In 1947, von Horn was appointed military attaché in Oslo, and the following year he moved to Copenhagen where he had received a similar appointment. In 1949 he returned to Sweden and took a position at the Northern Småland Regiment (I 12) and the following year he was promoted to colonel and commander of Kronoberg Regiment (I 11) in Växjö. He stayed there for seven years; in 1957, he was appointed commander of Malmö Defence District (Fo 11).

von Horn was married three times. In the first marriage 1925–1944 he was married to baroness Maud von Otter (1904–1974), the daughter of major, baron Carl-Gustaf von Otter and Elisabeth (née Krook). He married a second time in 1945 to Britt (Bibi) Englund (1919–1962), the daughter of the wholesaler Ernst Englund and Ebba (née Wistrand). He married a third time in 1964 to Elisabeth Liljeroth (born 1932). von Horn died in 1989 and was buried in Källstorp cemetery in Trelleborg Municipality.
