The War Book of the German General Staff Being "The Usages of War on Land" Issued by the Great General Staff of the German Army — Context and Discussion

Structure and Authority of the Manual

The manual is organized into sections that systematically address the conduct of war, from the treatment of envoys to the handling of prisoners. Morgan notes that the text is “by no means elegant,” but its plain, directive style serves an instructional purpose. The manual’s authority is asserted through its origin: it is issued by the Great General Staff and “takes precedence over all other publications whether military or legal.” This hierarchical claim is reinforced by the manual’s internal references to “regular usages of war” that officers and even privates must know. The structure reflects a top-down dissemination of rules, with each section building on the assumption that military necessity overrides legal niceties.

Recurring Image of the Flag of Truce

A recurring motif is the flag of truce, which the manual treats as a fragile instrument of communication between belligerents. The text details the envoy’s appearance: “mounted on horseback,” accompanied by a trumpeter and flag-bearer, or on foot with a bugler. The white flag—or even a “white pocket-handkerchief”—must be “universally recognized.” Yet the manual immediately qualifies this inviolability: an envoy who abuses his position for espionage may be captured or condemned. The image recurs in discussions of etiquette, where the manual warns that a parley “may serve as a cloak for obtaining information.” This tension between custom and suspicion permeates the manual’s treatment of all interactions with the enemy.

Movement Between Scenes of Negotiation and Combat

The manual’s sections move abruptly from the formalities of truce to the realities of combat. In the excerpt on envoys, the text shifts from describing the envoy’s approach—“makes for the enemy’s outpost”—to the conditions under which he may be shot. This juxtaposition mirrors the manual’s broader structure: it oscillates between codified customs and the prerogatives of military necessity. Morgan’s introduction reinforces this movement by contrasting the manual’s language with the “scraps of paper” view of Hague Conventions. The reader is constantly shuttled between the ideal of regulated warfare and the manual’s underlying premise that “the only ‘laws’ recognized by the German Staff are the military usages” it itself defines.

Voice and the Rhetoric of Calculated Egotism

The manual’s voice is impersonal and prescriptive, using phrases like “it is recommended” and “it is the right of every army.” This detached tone masks a calculated logic: rules are observed only when they serve self-interest. Morgan identifies this as “a calculating egotism” that underpins the entire text. For example, the manual states that an envoy who is not received “must immediately rejoin his own army; he must not, of course, be shot at on his way.” The word “of course” implies a natural limit, yet the manual elsewhere permits shooting if the envoy violates conditions. This rhetorical pattern—asserting a rule, then qualifying it with exceptions—reveals a system where legal protections are contingent on the enemy’s compliance and the army’s convenience.

Readers approaching this text should attend to the interplay between the manual’s explicit rules and the implicit assumptions Morgan highlights in his introduction. The manual is not a neutral code but a document that reveals how a military institution conceptualizes law as a tool of war. Morgan’s footnotes and marginal notes provide a critical apparatus that helps trace the manual’s intellectual pedigree. For those interested in the legal and moral dimensions of warfare, this edition offers a primary source that is as revealing for what it omits as for what it prescribes.

I keep returning to that stark German manual, its cold logic and the way it quietly dismisses the Hague rules, and it makes me think of the grenadiers who had to live through the consequence of such thinking. The manual’s detached paragraphs feel distant, but reading their story brings a strange warmth to that coldness. The Grenadier Guards in the Great War of 1914-1918, Vol. 2 of 3 — Story, Setting & Ideas always grounds those abstract pages in something truly human.
