Operation Tiger (Java)

Operation Tiger was a series of World War II covert reconnaissance and infiltration missions conducted by the Netherlands East Indies Forces Intelligence Service (NEFIS) on Japanese-occupied Java between late 1942 and 1943. Small parties were landed (typically by submarine) on Java’s south coast to collect intelligence and, where possible, establish clandestine contacts. Some Dutch submarines operating from Australia undertook covert intelligence tasks, including landing agents on the Javanese coast. Many of the Tiger parties were captured by the Japanese military police (Kempeitai); multiple participants were later executed.
