28 April 1945,
Italian partisans executed fascist dictator Benito Mussolini. After the fall of his regime, he was caught in flight to Switzerland in a checkpoint for partisans, along with his lover Clara Petacci and three other fascist authorities, all disguised as Spaniards. They were shot on the shore of Lake Como and transferred to Milan to hang them upside down in Plaza Loreto, in honor of the fifteen partisans who hung them ten months earlier in the same place.
