Petty Officer Michael Thornton and Lieutenant Thomas R. Norris were among the comparatively few American sailors left in South Vietnam in October of 1972. The so-called “Brown Water Navy” had been “Vietnamized,” and most of the remaining U.S. Navy personnel were advisors to the Vietnamese Navy (VNN). But being an advisor did not necessarily mean being out of harm’s way, especially when the North Vietnamese invaded South Vietnam in force in the spring of that year.
