South Vietnamese troops raid Cambodia – with US aid: archive, 30 April 1970
30 April 1970: The American Command in Vietnam confirms that it provided military support for “counter attacks against North Vietnamese and Vietcong forces”
Saigon, April 29
South Vietnam admitted for the first time tonight that its troops have crossed over into Cambodia – and with United States military support – to “destroy enemy bases along the border” in the Parrot’s Beak area.
Soon after this was announced in a communique from the South Vietnamese Defence Ministry, the American Command in Vietnam confirmed that, with the advance approval of Washington, it had been involved in today’s operation. US air, logistical, medical, and artillery support were provided, and it appears that American advisers accompanied the troops on what the Command described as “counter attacks against North Vietnamese and Vietcong forces.”
