In July 1959, the North Vietnamese army increased its participation in attacks on government forces. The attacks usually took the form of North Vietnamese regulars attacking a defended position, overcoming most of the resistance and then letting their Pathēt Lao allies claim the victory by occupying the position. Two months later, North Vietnam created a new organization known as Group 959 located inside Laos at Na Kai. Group 959 became in effect the Vietnamese supreme command controlling, organizing and equipping the Pathet Lao. The group would continue to exist until 1968 when it was rendered redundant through the takeover by North Vietnam's army of the war inside Laos.
