Marines and Chinese Forces
in Chosin Reservoir Area

The 581st Signal Radio Relay Company had a stations at the Chosin Reservoir with the Marines. My station, Jade Relay 2, was on the coast at the point indicated by the X. We fed south to Wonson and west to Koto-ri. The Army picked that spot at Jade 2 because we had a straight shot to Wonson. Our transmitters, only 50 watts and FM, normally has an outside range of 50 miles. Over water the beam tends to bend and it was successful. We changed frequencies and called for several days before contact was made. Great sighs of relief followed. The Marines were in great trouble and we were vital to their success.
