by the military junta. On 1 November 1974, Nicoletti placed a remote-controlled bomb under the yacht of the police chief of the Argentine Federal Police, Alberto Villar, who was killed together with his wife. On 22 September 1975, while the destroyer was still under construction in Buenos Aires, Nicoletti placed an explosive charge under the hull which caused it to sink. Later in the decade, Nicoletti was arrested by the infamous Grupo de Tareas 3.3.2 of the Navy Mechanics School, but escaped serious punishment by cooperating with the authorities. Soon, due to his cooperation and expertise, he managed to get himself appointed to carry out a similar submarine attack against a Chilean ship because tensions between Chile and Argentina were high due to the Beagle dispute. This attack was not carried out in the end because the disagreement between Chile and Argentina was finally resolved peacefully. Nicoletti was then sent to Venezuela as a spy but he was discovered and had to return to Argentina. Shortly after he settled in Miami, but when he heard of the Argentine invasion of the Falkland Islands he immediately got in touch with the Argentinian government in case his services were needed and he was instructed to return to Buenos Aires. The other two commandos, both also ex-Montoneros, were Antonio Nelson Latorre and another man who went by "Marciano," while remaining anonymous to this day. Both had participated with Nicoletti in earlier sabotage plans. In the event of capture, Argentina would deny all knowledge. The agents were to say they were Argentine patriots acting on their own. They had orders not to do anything which could involve or embarrass Spain, to sink a British naval vessel and to get express approval from Anaya before carrying out any attack. When planning the operation in Argentina it was decided that acquiring or manufacturing explosives in Spain would prove too difficult and so two explosive mines with timed detonators would be shipped to Spain via diplomatic pouch and would be delivered to the commando group in Spain. Italian limpet mines were acquired for this purpose and shipped to Spain in diplomatic pouch as planned. Situation in Spain At that time the political climate in Spain was unstable with the government of Leopoldo Calvo Sotelo having political difficulties on many fronts, including with the military who mistrusted him.
