This book was first published in hardback in 1993, at a time when the 'Ostfront' was rather less well known in the West.
This is the first book to be written on what was probably one of the decisive battles of the war. Had Hitler won, the war might well have continued for much longer, with uncertain consequences; eg time for further development of the V weapons, and jet aircraft.
Like Napoleon, Hitler only understood offensive warfare, and Operation Citadel was a huge gamble, coming so soon after the defeat at Stalingrad.
Of special interest is the chronical of the repeated delays in getting the offensive started - the order was signed by Hitler on 15 April 1943, but, despite Manstein's pleas, it did not start until 4 July.
By this time, however, Bletchley Park had been tracking German plans since April, and passing its findings to Stalin via the Lucy network in Switzerland.
This chimed in with the plan which Zhukov had been working on since March.
All this is described in great detail by Robin Cross, such that we do not get to the actual battle until Chapter 7.
The climactic of the battle, around the village of Prokhorovka, gets a full chapter in itself. On 12 July 1943, in a "colossal melee, fought at practically point blank range" the German Tiger tanks lost the advantage of range over the T34s. The thoroughness of the Russians prepared defences had paid off.
They expected the German attack to resume on 13 July, but the advantage had now swung to the Russians. On 17 July the Russian counter-offensive began. As Cross records, the Russian defences had been so effective as to sap moral "to the point where the will to press home attacks ... was ebbing away."
The war in the east was lost.
