My friends was it the NORTH Vietnamese Communists that got rid of them?
Yes it was. The southern Communists were almost all dead or surrendered. I was a radio op in c-47s listening to the NVA ops on the ground after the Tet fiasco and the accents were all northern and desperate for help and instructions. Some was in clear speech because the radio ops with the codes were dead. They got back instructions to hide their weapons and try to get back to the North.
