France and Belgium 1917.Vol III. The Battle of Cambrai. OFFICIAL HISTORY OF THE GREAT WAR.

One of the best of the Official History volumes. Cambrai where tanks were first used en masse was initially a great victory; the church bells rang out in celebration. Within a few days the Germans had struck back and victory turned to ashes and Douglas Haig ordered an enquiry into the disaster. A very readable account of a most important battle.
