"Marine Sergeant Hakkenberg fought with the Netherlands Marine Brigade in East Java in 1948 and 1949 until the Indonesian army became too strong. It was during this period that he received the Knight in the Military Order of William 4th Class. After this he ended up in New Guinea, where he trained the Papuan army." Source:
