This is a factual account of Operation Grief (Griffin), the German false-flag operation during the Ardennes offensive of late 1944. The operation and its leader, SS Lieutenant Colonel (SS-Oberstürmbannführer) Skorzeny, are the stuff of legend.
Anderson debunks the legend, and presents the facts, insofar as they can be determined (he notes in his blog that "Doomed secret agents don't write journals or reports and their commanders didn't keep intricate records"). The result is a compelling piece of work that reveals the unvarnished truth of the operation's planning and execution.
This is an easy to read, well researched piece, covering a part of history that is well known, but about which few factual accounts have been written.
