End of the Affair: The Collapse of the Anglo-French Alliance, 1939-40

In this review of End of the Affair: The Collapse of the Anglo-French Alliance, 1939-40, the reviewer finds a focused diplomatic and military history best suited to readers who want a document-based reconstruction of why Britain and France failed to cooperate as war pressures mounted. Eleanor M. Gates presents a careful synthesis of unpublished documents and cabinet minutes that explains the book's central claim: strategic disagreements, mismatched expectations, and political fragility drove the rupture. This review highlights the book's strengths for historians and informed readers and the single biggest reason to read it - the depth of primary-source material that reframes familiar events.

Key Features

• Primary-source focus: Gates uses previously unpublished documents and cabinet minutes to give readers direct access to wartime decision making and internal debates.
• Diplomatic and military lens: The narrative balances diplomatic correspondence and military plans to show how strategy and policy interacted under crisis conditions.
• Chronological scope: Coverage from the uncertain early months of the war through France's collapse in 1940 allows readers to follow the alliance breakdown as it unfolds.
• Strategic analysis: The book examines competing war aims and the defense-versus-offense conflict to clarify why coordinated action faltered.
• Political context: Attention to France's internal political fragility helps explain constraints on French decision making during the crisis.

Who It's For

This book is aimed at readers of modern European history, military historians, and graduate students who value archival evidence and careful diplomatic reconstruction. Its emphasis on cabinet minutes and diplomatic correspondence will appeal to those who want the documentary basis behind policy shifts rather than a purely narrative popular account.

Readers seeking a broad popular survey of World War II, or an operational military history focused on battlefield tactics and unit movements, should look elsewhere; Gates prioritizes high-level strategy, diplomacy, and political decision making over granular battlefield narration.
