The Second Junta of Greece, under Ioannidis, overthrew Makarios just six months after Grivas' death. Ioannidis had been planning to overthrow Makarios in spring 1974, but the final decision to act was made on 2 July 1974 after Makarios decided to directly oppose the Ioannidis regime by expelling from the Cypriot National Guard 550 Greek officers. That meant the loss of military control of Cyprus for Greece as well as the humiliation of Ioannidis. The coup d'état of 15 July 1974 that overthrew Makarios were executed by forces of the Cypriot National Guard under direct instructions from Greece. The National Guard was led by Greek officers and consisted of Greek-Cypriot conscripts. The EOKA B members and other pro-enosis forces joined the National Guard in the afternoon of Monday 15 July 1974 in the fight against Makarios' forces. The coup was swiftly followed by the Turkish invasion of Cyprus on 20 July. This invasion took Ioannides by surprise, who failed to prepare Cyprus for a Turkish invasion and failed to coerce the Greek generals whom he had appointed to apply "Plan K" and provide military assistance to Cyprus. That marked the downfall of Ioannidis.
