Despite it’s sub-title, Spies & Commandos is actually about secret American and South Vietnamese efforts to conduct a secret war in North Vietnam. Spies & Commandos is an account of those unsuccessful Allied efforts to establish an internal resistance in the north. Since the extent to which those efforts were seriously intended to do more than divert enemy attention from the South, rather than establish a genuine underground in the North, remains unclear, the work is not entirely satisfactory.
