Over ten days in June 1954, a decade after the D-Day landings, the CIA sent twelve planes to drop bombs and propaganda on towns in Guatemala in support of a coup against the elected government of Jácobo Arbenz. They did only minor damage at first: one plane bombed the wrong radio station, another ran out of fuel and was forced to crash land in Mexico. A plane was dispatched to make a ‘hostile’ attack on Honduras with the aim of provoking a military response, but the Hondurans could not even agree on which airfield it had hit. In the last raid on 27 June, the SS Springfjord, a British merchant ship that had survived capture by the Nazis in 1940, was attacked in the port of San Jose. It was alleged to be unloading arms. After a warning pass – the ship's captain gave the pilot a friendly wave – a 500lb bomb was dropped down its chimney. It turned out to be loading coffee and cotton.
