Archie to Sam. A Short Operational history of Ground-Based Air Defense [308 Pages, 5.46MB] - Dr. Kenneth Werrell’s history of ground-based air defense performs an important service both to scholarship and, more importantly, to the defense of our nation’s freedom. It is perhaps human nature that we tend over time to lose sight of the lessons of the past, especially when they do not conform to certain cherished preconceptions of ours. That such myopia can be dangerous, if not downright disastrous, Dr. Werrell’s study richly illustrates. Without sentimentalism, he chronicles a pattern of lessons learned and too quickly forgotten as the marvel of air power was reminded again
and again of its limitations and vulnerability. In Korea and in Vietnam, the American people were stripped of their illusions of national and technical omnipotence. The unhappy outcome of those two conflicts was doubly lamentable because the lessons of World War II were—or should have
been—fresh in our minds. In that world war, as Dr. Werrell shows, relatively cheap ground-based air defense did make a difference: at Ploesti, at Antwerp, and at the Rhine bridges.
