On August 21, 1967, four A-6A Intruders of Attack Squadron 196 were tasked with bombing the Duc Noi rail yard north of Hanoi.

The following edited account of the action that day is taken from http://www.pownetwork.org/, and is believed to have originated with Project Homecoming II.
The route from the coast-in point was uneventful with the exception of some large weather cells building up. Further along their route they received indications of launched Surface-to-Air Missiles (SAMs) and observed bursting 85mm anti-aircraft fire.
Lieutenant Commander "J" Forrest G. Trembley, bombardier/navigator of one Intruder, reported he had been hit and he was advised to reverse course and return to the coast. He transmitted that he was experiencing no difficulty and would proceed to the target rather than egress alone. Commander Jimmy L. Buckley was the pilot of this aircraft. Several SAMs had been launched at this time and a transmission was made "Heads up for the Air Force strike" which was being conducted in the vicinity of the A-6 target. An aircraft was hit which was thought to be an Air Force aircraft.
The division leader was hit while in the target area and two good parachutes were observed. The crew of this A6, Commander William M. Hardman and Capt. Leo T. Profilet, were captured by the North Vietnamese. Both men were released from captivity on March 15, 1973.
The other three aircraft began their egress from the target. Surface-to-air missiles (SAMs) were in flight everywhere and the aircraft were maneuvering violently. A large weather cell separated them from the coast which precluded their egress further north than planned.
Another transmission was heard -- "Skipper get out" -- and the voice was recognized as that of Lieutenant Commander Trembley. A SAM detonated between two of the other aircraft, two parachutes and flying debris were observed. Lieutenant Commander Trembley transmitted, "This is Milestone 2, Milestone 1 was hit, 2 good chutes, 2 good chutes." The multitude of SAMs along with deteriorating weather may be the reason for the flight to ultimately stray well north of their planned egress track. It was believed that Lieutenant Commander Trembley's aircraft was shot down in the vicinity of the Chinese border.
In their navigation around the weather, one of the remaining two A-6 aircraft observed MIGS in a run out of the overcast above Lieutenant Commander Flynn's aircraft. Requests for assistance were radioed but went unanswered. The tracking of the aircraft by airborne early warning aircraft showed them crossing the Chinese border. The maximum penetration was about eleven miles. A visual search could not be conducted due to poor weather in the vicinity of the last known position.
Later that day Peking Radio reported "two U.S. A-6 aircraft were shot down when they flagrantly intruded into China airspace and one crewman was captured". Lieutenant Commander Flynn was held prisoner in China, his pilot, Commander Jimmy L. Buckley, was killed in the shoot down.
On March 15, 1973 Lieutenant Commander Flynn was repatriated to U.S. jurisdiction in Hong Kong and returned to the United States. The ashes of Commander Jimmy L. Buckley were returned by the Chinese in December 1975.
