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