Casualty Occurrence: Jeep ambushed between Chau Dac and and A-421(Ba Chuc)

From what I can remember John was cremated and then per his request wanted his ashes scattered over the Pacific Ocean.  Attendees, including his wife, Mary, daughter Barbara, son John, and others....most likely a representation of Special Forces, etc. gathered on a bluff in California (Carmel?) for the services. A Small plane (Special Forces?) flew overhead heading west over the Pacific Ocean where they scattered his ashes.   I remember him saying that he wanted this because his belief that the oceanic tides would sweep his ashes to Japan, a country and people he loved. Anton "Tony" Cistaro, Comrade, in arms

I would like to honor the memory of Major John Arnn, who I knew in the last few days of his life.

Major Arnn commanded the U.S. Special Forces unit in Chau Doc Province, on the Cambodian border in the Delta. I was assigned as the Assistant USAID rep in Chau Doc in December 1965. In the few days remaining to him. Major Arnn would lead his unit by my home each day on their morning run, and he would urge me to join them. He had made a personal commitment to get me in shape.

Major Arnn died December 26, on a ride through an outlying area of the province. Each time he rode by that mountain, controlled by the VC, he would sit in back of his jeep and spray the mountain with machine gun fire. That day the VC had anticipated him, and detonated an explosive under the jeep as it went by. Major Arnn and his driver were killed. His friend, my boss Tony Cistaro, was severely wounded and left for dead. May his soul rest in peace. Jim Perry
