O'Donnell, a military historian, recounts how during World War II, the Brenner Pass in the Alps, which linked Italy with Austria, became part of a covert operation to bring supplies and troops to the Third Reich. Using declassified files, private documents, and personal interviews with team members to tell the story, he describes how US spies led by Howard Chappell from the Office of Strategic Services were sent to sabotage the Brenner Pass by blowing up one of the tunnels. O'Donnell describes their training, the plan, and each part of the operation. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
