Plain of Jars
By 1 April, funding had been authorized for a total strength of 7,000 ADC troops. Seven CIA agents and five PARU teams had raised a guerrilla army ringing the Plain of Jars. The new militia blocked all exits from the Plain of Jars except to the southeast; that was held by Royalist regulars blocking the route to Vietiane. They were resupplied via contract with civilian airlines such as Air America and BirdAir. Supplies were landed at short takeoff and landing strips when available; otherwise they were parachuted in.
