On 19 December 1948, the Dutch made a final effort to gain control of the areas of their former colony of
Indonesia, which had
declared independence in 1945, that were still under the control of republican forces, by launching a "
police action" known as
Operation Kraai. Despite the military success of this operation, in which Dutch forces overcame Indonesian fighters and recaptured the whole of Java, including the Indonesian republican capital,
Yogyakarta, there was worldwide condemnation, including from the
United Nations (UN). On 31 December, the Dutch agreed to a ceasefire requested by the UN. The United States subsequently put pressure on the Dutch to negotiate with the Indonesian side, including issuing a threat to withhold post-war financial aid. The Dutch agreed. In January 1949, the
United Nations Security Council called for the release of the Indonesian leaders captured during the police action and for the Dutch to transfer sovereignty to Indonesia by 1 July 1950. In the face of this pressure the Dutch conceded defeat, and insisted on preliminary discussions with the Indonesian republican government. == Discussions ==
