The Indonesian invasion of South Maluku was a series of military campaigns and subsequent counter-insurgency operations conducted by the armed forces of the Republic of Indonesia (APRIS/TNI) against the Republic of South Maluku (RMS) following the latter's declaration of independence on April 25, 1950. The initial invasion phase saw Indonesian forces rapidly occupy key islands such as Buru, Kai, Tanimbar, and the administrative center of Ambon City by November 1950.
Following the defeat on Ambon, the RMS government and its remaining forces retreated to the island of Seram, initiating a protracted guerrilla conflict that lasted over a decade. The insurgency continued until the capture of RMS President Dr. Chris Soumokil in December 1963, although low-level resistance persisted thereafter.
Following the Dutch recognition of Indonesian sovereignty in late 1949, the political structure of the former Dutch East Indies was reorganized. However, tensions remained high in eastern Indonesia, particularly among Ambonese Christians who had formed the backbone of the Royal Netherlands East Indies Army (KNIL). Fearing marginalization and violence under the centralized Republic of Indonesia, they sought independence.
On April 25, 1950, the Republic of South Maluku (RMS) was unilaterally declared independent, leading the Indonesian government to authorize military action to suppress the separatist movement and integrate the region into the unitary state.

The invasion started with naval operations against the outlying islands, led by colonel Abdullah. The Barat Daya Islands in the south were captured in May 1950 without a fight, followed by the Aru Islands (3 June), Tanimbar (25 July), Kai (30 July), Geser (6 August) and Banda Neira (August).[4]

The first battalion to land, the Pattimura Battalion, advanced south towards the town of Namlea.[5] The first engagement against APRMS defenders occurred at Milestone 4 north of Namlea. Due to the preparedness of APRMS forces which fired towards the APRIS advancing in open terrain, APRIS forces lost three men from hostile fire.

Lesteluhu acknowledged that he had fallen victim to RMS "provocateurs" and agreed to provide his service to APRIS.
