Vanderpool Document on the Attachment of Guerrillas to US Army Units


Col. Jay D. Vanderpool was the Liaison Officer sent by Headquarters, Southwest Pacific Area (SWPA) Command to southern Luzon, including Batangas, to coordinate guerrilla activities in the area in preparation for the Allied invasion. Transcriptions of a selection of his communications either with guerrilla units or offices of the United States Army are compiled in this section. In this page is a transcription1 of a supposed “secret” document from Vanderpool issued to guerrilla commanders on the recruitment and attachment of their personnel to United States Army units.
