One of the catalysts driving the atrocities committed by Indonesian Pemuda against the native Eurasian civilian population was the inciteful Republican propaganda.
Republican propaganda during the revolution was used as a form of political warfare, by communicating loaded messages to produce emotional responses and influence the attitude of the masses, with the objective to further its political and military agenda.
Effective means of mass communication were the broadcasts of republican radio stations such as 'Radio Pemberontak' and speeches during mass demonstrations.
The supreme republican leader Sukarno had mastered these forms of communication.
However during the Bersiap period the republican strategic agenda had not yet fully found a common ground and unitary message how to achieve its single mission of independence.
Due to this paradox republican communication often fluctuated between moderate (political) and radical (military) messages.
The Republican military declaration of total war (14 October 1945) states: ""When the sun sets, we the Indonesian people are in war with the Dutch.""
The declaration then continues with clearly targeting civilian groups: ""With this declaration we order all Indonesians to find their own enemy – Dutch, Indo or Ambonese.""
In his speeches the revolutionary leader, Sutomo, specifically aims at the Eurasian population, verbally reducing them to bloodhounds.
In Surabaya, Sutomo had a radio studio and transmitting equipment at his disposal.
The first transmission was on 13 October 1945, but could only be received in Surabaya and parts of East-Java.
From 16 October 1945 the radio broadcasts could be heard all over Indonesia.
The next Sutomo speech was broadcast on 14 October and another on the evening of 15 October.
This was the evening of "black monday", the day Dutch & Eurasian citizens were rounded up and killed at the Kalisosok and Bubutan prisons in Surabaya.
""Torture them to death, destroy those bloodhounds of colonialism to the root."
[…] "The immortal spirits of your ancestors demand of you: revenge, bloody revenge!""
, Sutomo, Jogjakarta, 24 November 1945.
Soon in the streets of the capital Batavia graffiti on the walls showed explicit slogans: ""Death to the Ambonese and Indos!""
The only pro-Dutch armed forces that existed on Java were small re-grouped South Maluku KNIL units.
These so-called 'Ambonese' or 'Belanda Hitam' (English: Black Dutch) as they were called by other Indonesians consequently retaliated any provocation or attack by 'Pemuda'.
Among the millions population of Java their numbers of approximately a few thousand were small, but in Jakarta their autonomous contra-terror operations escalated to the point that the British military leadership wanted to de-mobilise them from the city.
Young Eurasians seeking revenge for atrocities committed by the "Pemuda" sometimes joined them (for instance in Bandung were they established an autonomous fighting unit called 'Andjing Nica', along the lines of a KNIL battalion), giving this part of the Bersiap the nature of a civil war.
Indonesian leaders such as Sukarno and Sjahrir attempted to call for calm, and even groomed the Eurasian population to join the revolution, but were unable to prevent the atrocities.
The small town of Depok, pre-dominantly occupied by native Christians, was one of the first places to be destroyed.
Many of its inhabitants were tortured and killed by the "Pemuda".
The ferocious mix of social revolution, xenophobia, opportunistic crime and feral populism that resulted in the "Bersiap" atrocities surprised and horrified not only the British commanders, but also moderate Indonesian leaders.
In reflection the Islamicist leader Abu Hanifah who later became minister of education and ambassador admitted: “The Indonesian revolution was not totally pure.” But while western-educated Indonesian leaders were deeply shaken by what they witnessed, many Indonesian accounts of the time considered the violence inevitable, and even morally neutral.
