Following World War II, the Royal Netherlands East Indies Army (KNIL) launched a military campaign in 1947 to try to re-establish Dutch control of Indonesia. The infantry regiment 4-11 departed on 5 February 1947 on the "Johan van Oldebarneveldt" for Indonesia, where it arrived on 5 March 1947. The regiment consisted of young boys recruited for obligatory military service, among them was Barend Booi.
