Hans Delbrück.




Delbrück was born in Bergen on the island of Rügen, and studied at the universities of Heidelberg and Bonn. As a soldier, he fought in the Franco-Prussian War, after which, in 1874, he became for some years tutor to Prince Waldemar of the German imperial family, a brother of the future emperor, Wilhelm II.[1] He served in the Reichstag from 1882 to 1883,[2] and afterward, in 1883, he became an editor of the Preussische Jahrbücher, a noted political magazine. He assumed charge of this publication in 1889,[1] and kept working on it in that capacity until 1920.[3]




Overall, Delbrück's works tried to place military history in the framework of general history. He regarded warfare as a cultural feature of societies, subject to evolution and influenced by the economy and the political system. His works, however, were not translated into English for some time, hence the reputation of him held by professional military theorists in English-speaking countries has not reached the significance of Clausewitz, for example.

Ancient warfare[edit]

Delbrück's conclusions regarding ancient warfare challenged historiography in so far as he tried to show that the figures for armies in antiquity were inflated in the original sources, and that, contrary to what is stated in most writings, the winner in a battle usually had more troops than the loser. Consequently, he gave completely different interpretations to some of the most famous battles in history, like Marathon, Gaugamela, and Zama by concluding that the advantage the Roman armies had over the "barbarians" rested, not so much in their discipline and refined tactics, but rather in their superior logistical support.[citation needed] The Romans were able to raise and maintain huge armies on the field, while the "barbarians" were unable to match their numbers. The theory aimed to criticize Germany's political class and practice of warfare which were under the heavy sway of nationalistic ideas at the time.[citation needed]

Medieval warfare[edit]

Regarding medieval warfare, Delbrück's findings were more controversial.[according to whom?] He made a distinction between knights (mounted warriors) and cavalry (an organized mass of mounted troops), and regarded the medieval warrior as an independent fighter, unable to join others and form units with tactical significance. This conclusion was contested by later scholars, in particular the Belgian historian J. F. Verbruggen.

Modern warfare[edit]

When moving into modern warfare, Delbrück showed his intellectual roots in Clausewitz as he made a distinction between two possible strategies in war: 'exhausting' the enemy and 'throwing down' the enemy (in German, Ermattungsstrategie and Niederwerfungsstrategie, respectively; often mistakenly translated as 'attrition' and 'annihilation'). These were derived from Clausewitz's distinctions between strategies seeking limited objectives and strategies aimed at rendering one's opponent militarily helpless, the latter often confused with the concept of "Total War" advocated by Ludendorff and rejected by Delbrück during WWI. The choice depended on the nature of the political objectives and existing political and economic limitations, as well as on the correlation of forces. He applied this analytical tool to the wars of Frederick the Great, concluding that, due to their numerical inferiority, the Prussians had pursued a strategy of exhaustion. His overall treatment of this era was, however, disappointing,[according to whom?] in part because Delbrück overlooked the Spanish wars. Delbrück was also very critical of his country's strategy during World War I. He said it would have been much better to seek victory in the Eastern front, gain minor objectives on the West and then seek peace. This was one example of the general principle, Delbrück maintained, that military and political maneuvers should be integrated.

In fiction[edit]

In Mel Brooks's comedy Young Frankenstein, Doctor Frankenstein sends his assistant, Igor, to retrieve the brain of Hans Delbrück for transplant into Frankenstein's monster. The tag on the tank containing the brain reads "scientist and saint", so it is debatable whether Brooks intended this or a fictional Delbruck.


In Victor Serge’s novel Unforgiving Years (Les Années sans pardon) the character Herr Schiff - an old German professor loyal to the Nazi regime, demoralized and disoriented in war-ravaged Berlin in the closing days of the Second World War – rereads Hans Delbrück’s The History of Warfare: “Lately, it was true, the sense of most of what he read escaped him; but being incapable of inattention, the mechanical act of reading acted upon him like a sedative. His cheek cupped in his hand, he reread the works he admired out of duty.” Hans Delbrück appears in the professor’s thoughts again while contemplating the meaning of the war as American soldiers overtake Berlin: “The Second World War was already down as a great historical tragedy – a quasi-mythological one – which nether Mommsen, Hans Delbrück, Gobineau, Houston Stewart Chamberlin, Oswald Spengler, or Mein Kampf could elucidate entirely…”
