"Although Moltke did not follow Clausewitz's teachings on the proper relationship between war and politics, on many other points he was the key link between On Wars philosophical speculations and the theory and practice of the Prussian army. Writing after the Second World War, General Staff officer Hermann Teske wrote that Moltke was the incarnation of the Clausewitzian theory. In the essays printed here, the reader will find ample conformation that Moltke employed Clausewitzian thinking and specific terms in numerous cases. Both Clausewitz and Moltke emphasised the primacy of battle and annihilation of the main enemy army. Both accepted uncertainty in warfare and emphasised improvisation over permanent or binding doctrine. Both emphasised the need for speed in making and executing decisions rather than lengthy searches for ideal solutions. Both emphasised moral factors in war and the need for independent action by local commanders, although Moltke certainly carried this farther than did Clausewitz. Both rejected the idea that systems could ever replace individual talent, and neither believed that any firm rules were possible in warfare."
