WWI questions and answers

The case for the system is that it worked while Bismarck ran it, since no war between great powers broke out between 1871 and 1890 and Germany used its alliances to restrain its partners as much as to protect itself. The case against it is that this peace rested on secret and contradictory promises, such as the Reinsurance Treaty and the Dual Alliance, that only Bismarck could balance, and that the Dual Alliance of 1879 tied Germany permanently to Austria-Hungary’s Balkan fears. Historians who emphasise structure, such as Christopher Clark, note that the bloc system of 1914 grew from the abandonment of Bismarck’s methods after 1890, when his successors let Russia go and then alarmed Britain. Others, following Fritz Fischer, stress the continuity of German ambition from the 1890s to 1914. A balanced judgement is that the system postponed the consequences of German unification without resolving them. The lesson travels well beyond 1914, because a security order that depends on one person’s skill is fragile, whereas one built into institutions can outlast its inventor.

Each crisis has a strong claim. The Bosnian crisis created Russia’s determination never to retreat again and set the pattern of German support for Austria-Hungary, so it best explains how the eastern powers behaved in July 1914. Agadir explains the west, because it convinced British leaders that Germany sought to dominate Europe and tightened the naval links with France that made British neutrality unlikely. The Balkan Wars changed the situation on the ground, removing the Ottoman buffer, doubling Serbia and persuading Austria-Hungary’s leaders that only war would solve their South Slav problem, which is why many historians, Christopher Clark among them, give them the greatest weight. A strong answer weighs distance against intensity, since Bosnia shaped attitudes while the Balkan Wars created the situation in which those attitudes were acted out. It should also admit the limits of the argument, because each crisis ended peacefully and none made war inevitable. The wider point is that narrow escapes shape behaviour, and the conclusions drawn from a near miss can be more dangerous than the crisis itself.

The great historians’ quarrel. The “sleepwalkers” reading stresses the machine: alliances, timetables and misread signals produced a war nobody wanted at that scale. The Fischer school answers with documents: Vienna wanted a Balkan war, and Berlin knowingly risked — some say sought — a continental one while its window was open. A fair verdict distinguishes levels: the system made escalation easy, but specific men in Vienna and Berlin chose escalation at each branch point, and Russia’s early general mobilization shortened everyone’s fuse. The transferable lesson is uncomfortable: deterrence systems that reward moving first convert crises into wars — a lesson the nuclear age relearned with different arithmetic.

Interrogate the margin. “Nearly worked” assumes the last 50 km were like the first 400 — but the right wing at the Marne was at the end of unpaved supply lines, short two corps, its horses dying, its men marching on bleeding feet, against a defender being fed by intact railways radiating from Paris. Logistics historians argue the plan’s culminating point arrived on schedule regardless of Moltke’s choices; operational historians point to real German errors (the drift east, the gap, Lorraine). Both agree on the deeper point: a plan that requires perfection from men, horses and enemies is not a plan but a wish — and Germany had bet its entire strategic position, including Britain’s neutrality, on it.

Hold two truths at once. Real incompetence and callousness existed — commanders who repeated failed methods for years, staffs that never saw the mud. But the caricature explains nothing: every army on every front, brilliant or stupid, produced the same deadlock, because the problem was structural — firepower without mobility, offense politically mandatory. And the armies demonstrably learned: compare the Somme’s first day to the BEF’s 1918 all-arms method (Chapter 12). The fair question for any commander is not “did men die for meters?” but “did he adapt at the speed the evidence allowed?” Some did; some did not; the system guaranteed the tuition would be paid in lives either way.

Make both cases honestly. For the concept: the Ottoman Empire was the bloc’s weakest member; the straits were the only route to resupply Russia at scale, whose shell famine was real; success might have swung the neutral Balkans. Against it: the naval-only attempt forfeited surprise; minesweepers crewed by civilians turned back under fire; the land plan assumed terrain and an enemy that didn’t exist — ridge country, and an Ottoman army that fought superbly under Kemal on interior lines. The execution was unarguably botched (August’s Suvla landing met almost no opposition and dug in on the beach). Most historians now judge: a genuine strategic idea, of a difficulty its authors never grasped — the gap between “worth trying” and “achievable with 1915’s tools” is where 130,000 men died. The meta-lesson: grade strategies on the capabilities you have, not the ones the map assumes.

Steelman it first: with the front unbreakable (Ch. 5) and Germany facing superior combined resources, forcing a faster mutual consumption genuinely favored the Entente — and by 1918 German manpower did run out first; the blockade was attrition too, and no one calls it thoughtless. Now the indictment: Verdun shows attrition’s fatal dependence on an exchange-rate you cannot actually control, and on treating your own men as a fungible input — a premise that corroded every army’s morale and broke two of them (Russia’s, France’s — partially) before it broke Germany’s. The defensible synthesis: attrition was rational as a framework (win the production-and-manpower war, attack only with favorable method), irrational as a battle plan (“bleed them at point X”). The distinction between strategic patience and tactical butchery is the whole lesson of 1916 — and most of its tragedy is that it took 1916 to learn it.

Try the distinctions in turn. Method: stop-and-divert versus sink-on-sight — real, but it tracks capability, not virtue; Britain could afford the gentler method because it had the surface fleet. Visibility: drowned passengers versus rickets statistics — morally arbitrary, yet it governed world opinion. Legality: both sides stretched or broke prize law; Britain’s food-as-contraband was an innovation too. Proportion and intent: both aimed at the enemy’s war-sustaining economy knowing civilians would pay first. An honest answer probably lands here: the difference is one of degree and optics more than kind — which is exactly why the century that followed regulated neither out of existence, and why “economic weapons kill quietly” remains a live question from sanctions debates to siege warfare today. Moral clarity about slow weapons is this chapter’s hardest exercise.

It captures something real: the war’s causes were European, its decisive fronts were European, and the rest of the world was largely conscripted into it through imperial ownership. But push back with this map. For Japan and its neighbors this was a Pacific power transition, not Europe’s quarrel. For the Ottoman lands it was an imperial collapse with local wars — Arab revolt, Armenian genocide, Anatolia’s partition — whose stakes were entirely their own. For India, Africa and Indochina it was the event that turned abstract subjecthood into blood tax, and so began the end of the empires themselves. Perhaps the fairest formula: a European war that could only happen at world scale because Europe owned the world — and that, in fighting it, broke the ownership. Which is why the “world” in its name grew truer every year after 1918.

Line up the variables. Grievances: nearly identical — senseless offensives, leave, food. The state behind the army: France had a functioning republic, rail-fed cities, and allies delivering; Russia had a collapsed autocracy, a starving capital, and no credible peace-or-victory story. The repair on offer: Pétain could change tactics and conditions because policy allowed defense-until-1918; no Russian government could offer “defense until better times” — the Provisional Government had staked its legitimacy on attack. Political alternatives: French soldiers had no rival state to defect to; Russian soldiers had the Soviets, and a party bidding peace and land. Conclusion worth keeping: armies are load-bearing walls of their states — they crack along the building’s existing faults, not their own. The mutiny tells you about the trench; the revolution tells you about the country.

Separate the prize from the price and the clock. The prize was real but slow: grain, oil (Romania), a one-front war — assets that pay out over years. The price was immediate: a million-man garrison, allies and neutrals shown a portrait of German victory, and the abandonment of any negotiated exit (who negotiates with an appetite like that?). And the clock was American: the treaty’s gains could only matter if converted into victory before the summer of 1918 — which meant risking everything on offensives (Ch. 12) that consumed precisely the divisions the east had freed. The general lesson is about time-domain strategy: an asset that pays in years is worthless in a game decided in months — unless it changes the months. Brest-Litovsk didn’t; it just raised the stakes of losing them.

Run the alternatives. Stand on defense, shortened line, and negotiate: militarily soundest — the Hindenburg Line held attacks well into 1918 — but “negotiate” founders on what Berlin would offer; the regime that had just written Brest-Litovsk would not trade Belgium, and the Allies, dollars flowing and Americans landing, had decreasing reason to deal. Attack narrower but smarter — at the French, at supply hubs like Amiens or Hazebrouck from the start: perhaps prolongs the war, still meets the same arithmetic. Attack as done: a million casualties for salients. The honest answer is that 1918 was decided in 1917 — by the U-boat gamble that added America, and at Brest-Litovsk, which made compromise unbelievable. After those, Germany’s military choices could only select the shape of defeat: quick by offensive exhaustion, or slow by siege. The transferable lesson is severe: operational brilliance cannot repair a bankrupt grand strategy — it can only spend the remaining assets faster.

The case for continuing (made at the time by Pershing, later by many Germans’ enemies): occupation would have made defeat undeniable, forestalling the stab-in-the-back myth and perhaps the next war. The case against is what commanders saw in November 1918: another year of casualties (projected in the hundreds of thousands) against a still-cohesive retreating army, war-weary home fronts, influenza burning through every unit, revolution spreading — to achieve terms the armistice already secured in substance. Foch judged the armistice “the conditions of victory without the losses of storming Germany,” and most historians find that defensible on 1918’s information. The harder retrospective truth: legitimacy is also a war aim. The Allies won the war materially and lost the narrative inside Germany within five years — a warning that how a war ends politically can matter as much as that it ends. Weigh it against a million more graves, and notice the question has no comfortable answer.

Prosecution: the treaty humiliated without weakening — guilt clause, reparations, unilateral disarmament — handing every German government a unifying grievance and Hitler his platform; it scattered German minorities as ready-made pretexts; it excluded Russia and lost America, so the order had no guardians. Defense: the treaty was milder than Brest-Litovsk (Germany’s own 1918 blueprint) and than 1945’s partition; Weimar was strangled as much by the Depression, elite contempt for the republic and deliberate myth-making (the army’s own “stab-in-the-back”) as by any clause; and the treaty’s terms were being peacefully revised — reparations effectively ended by 1932, before Hitler mattered. The tenable verdict: Versailles did not make 1939 — choices in the 1930s did — but it made those choices cheap, by delegitimizing the peace it created and dissolving the coalition that could have defended it. Distinguish, always, between a wound and the decision to infect it: the twenties show reconciliation was possible; the thirties show what it cost to abandon enforcement. That double lesson — punish or reconcile, but resource whichever you choose — is the Great War’s parting gift to statecraft, unwrapped too late.

The claim fits the east and the south-east best. Poland’s eastern border followed the battle line of 1920, Vilnius and Memel were seized by force, and Lausanne recognised the frontier that Kemal’s army had won, so in these regions the treaties ratified facts made by soldiers. It fits the centre and west less well, where Versailles, Saint-Germain and Trianon drew frontiers that no army fought over in 1919 and the defeated states were too weak to resist. Even there the peacemakers often confirmed decisions taken by others. Plebiscites, votes in which local people chose their state, much like referendums, settled Schleswig and Upper Silesia, and new states had been proclaimed in Prague and Zagreb before the conference met. A careful answer separates the making of borders from their survival, because treaties could draw lines anywhere, while only lines backed by power, or by the consent of the people living along them, lasted. Judged that way, the instability of the 1923 map lay in the gap between borders on paper and anyone’s willingness to defend them, a gap that governments of every era should measure before they sign.
