Coba jelasin Since 1962 dari Ma'ruf Amin dalam bahasa jawa dong

In 1962 Indonesia launched a significant campaign of airborne and seaborne infiltrations against the disputed territory, beginning with a seaborne infiltration launched by Indonesian forces on 15 January 1962. The Indonesian attack was comprehensively defeated by Dutch forces including the Dutch destroyers Evertsen and Kortenaer, the so-called Vlakke Hoek incident.[8] Amongst the casualties was the Indonesian Deputy Chief of the Naval Staff; Commodore Yos Sudarso. Unbeknown to the Indonesians, Dutch Signals Intelligence had been able to intercept Indonesian communications, allowing Dutch forces to successfully anticipate Indonesia's infiltration attempts throughout 1962.[9] Forced to regroup, the Indonesians relaunched their campaign of infiltrations in March 1962. In the coming months over 500 Indonesian paratroops and special forces were covertly inserted into Dutch New Guinea, only to be decisively defeated by Dutch forces with the assistance of the indigenous population.[10]
