Cisarua
Tjisaroea ( Perfected Spelling: Cisarua) is a location on Java where during the 1945-1949 Indonesian National Revolution the Royal Netherlands East Indies Army ( KNIL) maintained a prison camp for soldiers convicted of breaches of military discipline.
The most well-known of those imprisoned there was Poncke Princen, who in 1947 served four months at the Tjisaroea Prison Camp on charges of desertion and later went over to the Indonesian National Armed Forces.
