Organization of Bureau of Constabulary (G-2 Information Bulletin, 10 October 1944)

This document is a "SECRET" G-2 Information Bulletin, dated October 10, 1944, and produced by the Military Intelligence Section of the General Headquarters Southwest Pacific Area (SWPA). The report details the organization, personnel, and current operational status of the Philippine Bureau of Constabulary (BC), a force established by the Japanese to maintain peace and order and suppress local resistance across the islands of Luzon, Visayas, and Mindanao. This intelligence was compiled from an authentic March 1944 roster and supplemented by information from local informants and broadcasts, providing a critical wartime snapshot. The bulletin is significant for its candid assessment of the BC's loyalty, noting that the Filipino personnel were "very luke warm to the Japanese" and were not proving to be an effective counter-guerrilla force. Evidence is presented showing BC soldiers deserting with arms, being disarmed by the Japanese due to distrust, or fleeing to join guerrilla forces in key areas like Samar and Panay. As a document produced just weeks before the American landing at Leyte, it provided Allied commanders with vital, actionable intelligence about the internal weaknesses and potential collapse of a major Japanese-controlled unit in the Philippines.
