1. The Communist forces in North Korea began building underground communication
tunnels in areas south of Heartbreak Ridge,. Korea, during the summer of 1951.
These tunnels are designed for the exclusive use of snipers, intelligence
agents, signal personnel, and. guerrilla units, who will launch guerrilla
activities after this area has-been recaptured by United Nations troops.
2. These tunnels are built in an area centered on Huaheiaoch'uants'un
(4e41)1 j*'j) (? Hwasoch' onch' 64, about 15 kilometers southwest of Heartbreak
Ridge. The tunnels radiate from that village and have exits in all nearby
villages. The tunnel exit for each village is built under beds in civilian
houses or in comparatively remote or hidden corners of such buildings. If
distance between villages is too great, "half-way exits" are built in the
large graveyards through which the tunnels pass. Graves used as exits are
covered or camouflaged in some form. Small underground warehouses have been
built for the storage of food and explosives beside each tunnel near the
exits. Guards and other personnel are stationed inside these warehouses to
manage them and to maintain the electric lighting and communications equip-
merit .
If United Nation forces fight over this area, these warehouses and tunnels
will be constantly used as places from which surprise attacks can be launched.
