The Police Actions (, also ), were two major military offensives that the Netherlands carried out on Java and Sumatra against the Republic of Indonesia during its struggle for independence in the Indonesian National Revolution. In Indonesia they are collectively known as the Dutch Military Aggressions (), although the direct translation is also used.
In Dutch historiography and discourse, the entire Indonesian War of Independence was euphemistically referred to for decades as "the police actions", as coined by the government at the time. In the Netherlands, the public impression prevailed that only these two short-term operations had been carried out, intended to protect the Dutch East Indies from a rebellion that required police action. This perspective ignores the fact that between the Indonesian declaration of independence in August 1945 and the cession of sovereignty in December 1949, a 52-month war had taken place.
Operation Product took place between 21 July and 5 August 1947. The Dutch greatly reduced and fragmented Indonesian-controlled territories, with a particular focus on the economic centre of Sumatra and the Port of Java. Lieutenant Governor-General Hubertus van Mook also advocated for the occupation of Yogyakarta, but the Dutch government decided against capturing the wartime seat of the Republican government at that time.
The (Marbrig) headquartered in Surabaya was tasked with securing territory in East Java containing 40 sugar factories, 70 coffee plantations, 72 rubber plantations, 5 tea plantations, and 3 cinchona plantations. It carried out amphibious landings at in Situbondo (Product North) and north of Banyuwangi (Product East) to occupy the eastern salient of Java. An offensive from Porong (Product South) connected Surabaya to the eastern salient through Pasuruan, before the marines pushed on to the Republican stronghold of Malang.
Operation Kraai (Crow) took place between 19 December 1948 and 5 January 1949. With the advantage of surprise, the Dutch captured Yogyakarta and arrested much of the Republican leadership, leading to the creation of an Indonesian government-in-exile in West Sumatra.
The Marbrig's actions in northeastern Java until 11 January are referred to as Operation Zeemeeuw (Seagull). The unit landed at in Tuban with the ultimate goal of occupying Madiun, but its advance was soon halted by a sizable anti-tank ditch some inland, dating back to the Japanese invasion of Java in 1942. From then on, the motorized columns were further delayed by the conditions of the wet season, destroyed bridges, and reliance on roads that no longer existed and were overgrown with teak forests. Because the marines lacked a dedicated engineer regiment, they had to cover much of the distance on foot and reached Madiun only after the city had already been captured by the regular army.
Eclipsed by the scale and notoriety of Product and Kraai, other Dutch offensive operations of the Indonesian Revolution included:
