the government. Shots were fired on the funeral procession (it had been prohibited from marching through the city but had insisted on doing so anyway) and three people, including Heredia, were killed, while many more were injured, before Reyes was finally buried. In June 1936, Castillo had married and his wife had received an anonymous letter threatening that he would soon be a corpse. He had begun training a socialist militia in the aftermath of the Reyes funeral riots. On the evening of 12 July, Castillo left his home in central Madrid to take up night duty. On the pavement outside he was killed by four men with revolvers who had waited for him through the late afternoon; the bullet holes on the surrounding wall are still visible today. The gun men escaped in the confusion amongst the late Sunday crowds and were never identified. Castillo was the second military officer with known socialist sympathies to have been murdered within five weeks (Captain Carlos Faraudo, an engineer who had been helping to train socialist militia, was killed in May). Nine Falangists were arrested in the aftermath. Aftermath In retaliation, that night at around 03:00, Castillo's close friend Police Captain Fernando Condés and other police officers and leftist gunmen, drove to the home of José Calvo Sotelo — leader of the monarchist party and a rival of José Antonio Primo de Rivera for leadership of the Spanish far-right — and asked him to come down to the station for interrogation. Driving with Calvo Sotelo in a police van of the Assault Guard, police officer and socialist gunman Luis Cuenca shot him in the back of the neck. (According to Hugh Thomas, although Cuenca was an "intimate friend" of Condés', Condés mostly likely had no idea that Cuenca intended to kill Calvo Sotelo; as the officer with his name on the paperwork for Calvo Sotelo's arrest, Condés considered killing himself; both Condés and Cuenca were soon arrested without incident). Calvo Sotelo's dead body was given to a municipal undertaker, without informing the undertaker of who it was. Cuenca then drove to the offices of newspaper El Socialista and told them what had occurred. As a deputy in the Cortes Sotelo had constitutional immunity from arrest and it is difficult to understand what other purpose than murder his kidnapping could have served. Both Castillo and Calvo Sotelo were buried 14 July; fighting between
