Operation Hickory was directed at reducing the combat strength and supporting infrastructure of North Vietnamese Army operating in and south of the DMZ. 2nd Battalion 3rd Marines boarded CH-46A Sea Knight helicopters on the USS Princeton to be inserted in the northeastern corner of the Hickory operating area. A few minutes later the choppers began to circle and gradually dropped elevation. Hotel made the opposed air assault into LZ Parrot, the opposition was strong enough so the LZ was closed to further landings until Hotel and supporting arms had secured the area. Just as soon as the chopper landed, we received small arms fire and mortar rounds to welcome us to the DMZ. Most of the day was spent ferrying the Battalion and supplies the hill top LZ in the DMZ. This was the Marines first incursion into the DMZ.May 28, 1967
