Vietnamese troops, in heavy ground and artillery assaults, drove Cambodian guerrillas out of their last major base near the Thai border, authoritative military sources in Thailand reported. Prince Norodom Sihanouk, the rebel leader, ordered a retreat to save the estimated 3,000 guerrillas defending the Green Hill base, across the border from the Thai town of Tatum, the sources said. It was the first time since invading Cambodia six years ago that the Vietnamese had overrun all the major rebel border bases.
