CAMBRAI, 1917: The First Blitzkrieg

In the pre-dawn darkness of 20 November, 1917, 378 British tanks and eleven divisions of infantry mounted the first truly mobile offensive in history, overrunning German positions with a rapidity comparable to the Blitzkriegs of the Second World War. Only a tenacious German defense-in-depth and an equally devastating counterattack employing the new, then-secret infiltration tactics, prevented the British from making a decisive breakthrough. Despite this setback, Cambrai was the forerunner of the mobile warfare of the Second World War.

Now, THE FIRST BLITZKRIEG: CAMBRAI, 1917 allows you to recreate this battle, one of the most significant in military history. Two players, each taking on the role of one of the historical commanders, use the Mapboard, 72 unit counters, and complete rules of play, to either change or recreate the historical results."

From the Game Notes:

"CAMBRAI, 1917 is a see-saw battle. The British have the advantage for the first three turns, but then it begins to slip away. The German commander than has the opportunity to stabilize the situation and seize the initiative with his counterattack. Therefore, the German should not give up if things look bad after the first few turns. The situation can change drastically every turn until the end of the game."
