Boven-Digoel was a detention camp in the Dutch East Indies on the banks of the river Digul, in what is now Boven Digoel Regency in Papua. The site was chosen in 1928 for the internal exile of Indonesians implicated in the 1926 and 1927 communist uprisings in Java and Sumatra. Indonesian nationalists not associated with the Indonesian Communist Party were subsequently also sent there. The camp was located in an isolated part of New Guinea, and surrounded by hundreds of miles of impenetrable jungle and hostile Papua tribes, so that contact with the outside world, and escape, was next to impossible. It was notorious for its endemic malaria.
