Operation Product was a Dutch military offensive against areas of Java and Sumatra controlled by the

Republic of Indonesia during the Indonesian National Revolution.[1][2] It took place between 21 July and 4 August 1947. Referred to by the Dutch as the first politionele actie, in Indonesia, the military offensive is more commonly known in Indonesian
history books and military records as Agresi Militer Belanda I (First Dutch Military Aggression).

The offensive was launched in violation of the Linggadjati Agreement between the de facto Republic and the Netherlands. The offensive resulted in the Dutch reducing Republican-held areas to smaller areas of Java and Sumatra, split by Dutch-held areas.[1]

Background

Netherlands abrogated the treaty and conducted military offensive toward Indonesian held territories due to by several factors: Financial -- the ~120,000 inactive Dutch soldiers, which includes significant number of Dutch-born conscripts, in Java was a significant financial burden on the Netherlands after the ravages of World War II.

Indonesian Communist Party.[4]

The Dutch military estimated they would need two weeks to secure Republican-held cities and six months for the whole of the Republican territory.[3] The offensive was intended to not include an attack on Yogyakarta, seat of the Republican government, due to high expected costs of fighting there.[citation needed]

Offensive

On 21 July, Dutch, whose forces armed with US produced lend-lease equipment and trained in modern warcraft, deployed three divisions in Java and three brigades in less-densely populated Sumatra. Operation Product in East Java consisted of three landing operations: Product North in Pasir Poetih, Situbondo, Product South in Meneng Bay, north of Banyuwangi, and Product East in Porong, Sidoarjo. Landings were supported destroyers, corvettes, minesweepers, patrol vessels, landing ships and vessels such as LSTs, LCIs, LCTs and LCVPs, tugboats and pontoons from Surabaya. [5] The operation resulted in the occupation of large, economically productive parts of Java and Sumatra. Republican army (Tentara Nasional Indonesia or TNI) ) tried to slow the Dutch advance by blowing up bridges, setting up roadblocks, laying ambushes and detonating roadside bombs. The aim of this was to be able to bring their troops to safety and, if possible, to apply the scorched earth tactic. A direct confrontation with the Dutch troops, who had much greater firepower, was avoided as much as possible.

Nevertheless, the TNI and its allies continued to conduct guerrilla operations from the rural areas in Dutch-controlled territory.

UN Security Council, and by the United States, who were calling for a ceasefire.[7]

Aftermath

The operation is rated as a military and economical success, as the Dutch managed to take over economically productive areas in Java and Sumatra, but a political setback as it attracted international attention to what was previously seen as an internal Dutch politic, and thus condemnation from other countries. Despite the government of the

Van Mook Line.[9] Both sides soon accused the other of breaking the armistice, with the Dutch complaining about pro-Indonesian insurgency behind the Van Mook Line. Meanwhile, Indonesia and third-party observers, including the Committee of Good Behavior, found not only the Dutch still maintained their naval blockade but also erected new land blockades on their side of Van Mook Line, and unilaterally created several (powerless) ethnic states in areas they conquered, when Linggadjati stated that the creation of a new federal state must be agreed by both Holland and Indonesia. Mutual distrust between the two sides, growing tension, and the belief that Indonesia was weakened by Darul Islam and socialist Madiun Affair, led Holland to conduct a second military offensive code-named Operation Kraai
