The conclusion of Professor Adams' popularly rendered, rather steamy four-volume history of World War II, both the military and diplomatic events and domestic doings, all presented newsreel fashion. Here, as the subtitle indicates, we witness the long coming but now inevitable Allied triumph over the Axis powers; it had taken 2,192 days, two hours, and 41 minutes we are told (Adams has built his recounting on a mixture of grand sweep and boggling minutiae) -- ""It was the most destructive war in the history of mankind, and mankind cannot afford another."" And so this bulky series ends as it began, more a sentimental journey than an analytical challenge. Adams is doubtless relieved that the long trek from the Sudetenland to the deck of the U.S.S. Missouri is finally finished. So are we. Now, perhaps, Professor Adams will turn his prodigious capacity for historical description to a subject with greater potential for original research.
