Acknowledgments viiIntroduction 11. Dieppe 5The Strategic Decision: Should Dieppe in August 1942 Have Been Raided? 5The Outcome: Minor Success; Profitless Movement; Major Disaster 13Later Decisions: Should Reserves Have Been Sent to Red and White Beaches-As Was Done? 15The Outcome: Wounding, Capture and Death 16Still Later Decision: Should the Operation Have Been Called Off-As It Was? 16The Outcome: The Return of Twelve Hundred; Crowing in Berlin 17How Bad Was the Outcome? How Significant the Battle? 17An Alternative Approach to Judging Decisions and Outcomes, That of Decision Science 18Did the Lessons of Dieppe Make Its Outcome, on Net, Good? 19What Pluses, Other Than Its Lessons, Did Operation Jubilee Have? 21Judging Decisions Apart from Outcomes 22Was Undertaking Jubilee a Good or a Bad Decision? 23How Much Did Ill Luck, Flawed Execution, or Poor Intelligence Contribute to the Bad Outcome? 25Given the Retrospective Consensus That the Plans for Operations Rutter and Jubilee Were Disastrous, Why Had They Been Approved? 28Could No One Have Prevented the Suicidal Folly? Did the Fault Lie in the Meta-Decisions-The Determinations of How the Decisions Would Be Made? 31 Meta-Decisional Issues: How Should Go-No-Go Determinations Be Made? How Were They Made on Dieppe? 34Did the British Authorize Rutter/Jubilee Expecting Failure-Perhaps Also Hoping for It and Even Acting to Sabotage the Raid? 35The Expected Value of Information 37What Should the Allies Have Done? 38Models of Governmental Decision-Making 38Conclusions 392.

Messina 86The Non-Decision: Should the Allies in July and August of 1943 Have Acted, More Than They Negligibly Did, to Prevent the Escape of 53,000 Germans Across the Strait of Messina? 87The Outcome: Allied Conquest of Sicily; German Escape; Italian Forsaking of the Axis Alliance 88How Good or Bad Was the Outcome of Operation Husky? 89Judgments on the Non-Decision of Failing to Interdict German Flight and Its Outcome 90What Affected How Bad or How Good the Outcome of Operation Husky Was? 91What Steps Might the Allies Have Taken to Have Captured or Killed Tens of Thousands More Germans in Sicily? 93Why Did the Allies in Sicily Not Take Any of Many Possible Decision Alternatives, Instead of Drifting into Their Actual, Inferior Non-Decision? 97Who, If Anyone, Was at Fault? 99What Should the Allies Not Have Done? 100Principals and Agents; Unity of Command 102Why Did the Germans in Sicily Do Better Than the Allies? 108The Perspective of Game Theory 108Risk Aversion 109Organizational Behavior 109How Bad Were the Consequences of the Non-Decision at Messina? 110Conclusions 1114.
