KV3/426 Japanese intelligence activities in Malaya

The file contains accounts of Japanese espionage in Malaya leading up to the fall of Singapore, described by Winston Churchill as the 'largest capitulation in British history'. Malaya, and the Fortress of Singapore in particular, is described as the 'perfect field for espionage'. Japanese espionage in Malaya was directed through the Consulate General in Singapore and the Defence Security Office (DSO) there recommended its immediate closure. However the warning was apparently ignored 'owing to reasons of political expediency'. The DSO in Singapore also noted the 'regrettable' fact that the 'average officer and man is notoriously careless in his conversation in public'. Various Malay and Japanese fifth column organisations are identified in the file including 'Kame' (or 'Tortoise') and the Black Dragon Society, an association of 'patriotic gangsters'. It is also claimed Japanese Buddhist priests were involved in gathering information. The file contains reports following the fall of Singapore in February 1942 including an interview with a Miss Gordon, a secretary at the DSO, in which she says they had 'reason to suppose there were at least six Japanese agents operating on the island' at the time of the invasion but they 'were never located, despite extensive searches'.
