Battle of Plaman Mapu

Date: April 27, 1965 • Location: Kuching, Malaysia

This milestone marked the outbreak and beginning of this historic period, which spanned 1963–1966.

The Konfrontasi, also known as the Indonesia–Malaysia confrontation or Borneo confrontation, was an armed conflict from 1963 to 1966 that stemmed from Indonesia's opposition to the creation of the state of Malaysia. Vital precursors to the conflict included Indonesia's policy of confrontation against Dutch New Guinea from March to August 1962 and the Indonesia-backed Brunei revolt in December 1962. Malaysia had direct military support from the United Kingdom, Australia, and New Zealand. Indonesia had indirect support from the Soviet Union and China, thus making it an episode of the Cold War in Asia.
