WWI questions and answers

The peace under Bismarck was real: no great-power war broke out between 1871 and 1890, and Germany used alliances to restrain partners as well as protect itself. Yet the Dual Alliance tied Germany to Austrian fears in the Balkans, while the secret Reinsurance Treaty created commitments difficult to reconcile with it. Christopher Clark stresses the change after Bismarck: his successors let Russia go and alarmed Britain, helping form the later blocs. Historians following Fritz Fischer emphasize continuity in German ambition from the 1890s to 1914. Bismarck postponed the tensions created by unification without resolving them. His personal skill sustained the arrangement; institutions that can operate beyond their inventor offer a more durable basis for security.

Bosnia best explains several attitudes visible in July 1914: Russia remembered its retreat, while Germany had shown that it would back Austria-Hungary. Agadir helps explain the western response, convincing British leaders that Germany sought European dominance and tightening naval links with France, making British neutrality less likely. The Balkan Wars have the strongest claim to have changed the immediate situation. They largely removed the Ottoman buffer, nearly doubled Serbia’s size, and strengthened Vienna’s conviction that only war could solve its South Slav problem. Christopher Clark is among the historians who give those wars particular weight. Bosnia shaped expectations; the Balkan Wars created the conditions in which leaders would apply them. All three crises nevertheless ended without a general war, and none made the decisions of 1914 inevitable.

The “sleepwalkers” interpretation stresses the alliances, timetables and misread signals through which a crisis produced a war no one had intended on that scale. Fischer's school points to evidence of Vienna's desire for a Balkan war and Berlin's willingness to risk, perhaps seek, a continental one while its advantage lasted. The two levels belong together. The system made escalation easier; leaders in Vienna and Berlin chose it, while Russia's early general mobilization reduced the time available to others. Under different conditions, the nuclear age faced a related danger: deterrence arrangements can reward a state for moving first.

The last 50 km were not simply another stretch like the first 400. German men and horses were exhausted, supply routes were long, and two corps had gone east; the defenders could draw on railways around Paris. Historians emphasizing logistics argue that the advance was reaching its limit. Operational historians also identify consequential decisions: the movement east of Paris, the gap between armies and the fighting in Lorraine. These explanations address different parts of the campaign. Command choices mattered within a plan that made enormous demands on men, animals and transport, and crossing Belgium had also risked British intervention.

The phrase has force where commanders persisted with poor methods, concealed failure or accepted losses too readily. It cannot, by itself, explain a front where even capable commanders faced defensive fire, ruined ground and reserves arriving behind the line. Political and alliance obligations also pressed them to attack. Armies learned: compare the first day of the Somme with the British Expeditionary Force's combined-arms methods in 1918 (Chapter 12). We should judge a commander by the objective, preparation and response to evidence as well as the cost. Some adapted better than others, and learning itself carried a terrible price.

The plan promised much: a route for supplies to Russia, which was short of shells; a threat to the Ottoman Empire; and influence over neutral Balkan states. The question is whether the Allies could obtain those gains with the means they had. The naval attack alerted the defenders, while civilian-crewed minesweepers faced fire and mines remained a formidable obstacle. The land campaign met steep ridges and determined Ottoman troops, including forces commanded by Mustafa Kemal, able to move along interior lines. At Suvla in August, troops landed against little initial opposition but did not seize the heights quickly. Roughly 130,000 men died in the campaign. The aims were substantial, but the difficulty exceeded the preparation and capabilities assigned to them.

The case for attrition begins with the difficulty of breaking the western front (Chapter 5). The Entente could maintain pressure with greater combined resources, including through blockade, and German manpower was under severe strain by 1918. But a sound expectation about the long war did not make any particular attack sound. Verdun showed that commanders could not dictate the exchange of casualties; prolonged losses also damaged Russian and part of French morale before Germany's defeat. An offensive must be judged by its methods, likely gains, losses and alternatives. Superior resources do not make the people committed to battle interchangeable.

The difference in method matters. Britain generally stopped and diverted ships; unrestricted German attacks sank them without warning, immediately endangering passengers and crews. Britain's surface fleet made its method possible, while submarines faced different dangers when stopping a vessel. Both governments sought to weaken the enemy's war economy knowing civilians would suffer, and both faced disputes over maritime law. A photograph can show drowned passengers more readily than a statistic can show deaths from hunger, but visibility does not determine moral weight. A judgment must weigh the methods, military purposes, foreseeable suffering and alternatives in each campaign. The slow harm of economic pressure deserves attention alongside the sudden loss of a ship.

The description captures the European origins of the crisis and the importance of the decisive European fronts. It also points to the imperial power that drew people elsewhere into the fighting. But the map shows why their experiences cannot be understood simply as casualties of someone else’s quarrel. Japan’s expansion changed the balance of power in East Asia and the Pacific. In Ottoman lands, the Arab revolt, Armenian genocide and partition of Anatolia had stakes of their own. In India, Africa and Indochina, service made imperial rule felt in lives and labor; those who contributed could ask why they lacked equal political standing. Such questions energized later challenges to empire, even though independence did not follow immediately. The war began in Europe, but its conduct and consequences reached beyond Europe.

Both armies had suffered failed attacks and heavy losses, and their soldiers wanted food and leave. In France, however, the republic, railway supplies and Allied support remained in place. Pétain could improve conditions and suspend great offensives while soldiers continued to defend. Russia’s autocracy had fallen, the capital faced shortages, and the Provisional Government had tied its authority to fighting on. Russian soldiers could look to soviets and a party promising peace and land, or leave to pursue land at home. France could hold until conditions improved. In Russia, another failed offensive intensified the dispute over who should govern and whether the war should continue. The soldiers’ grievances were similar; the institutions and alternatives available to them were not.

The eastern victory released divisions for the west and promised food and other resources. But Germany had to hold its new position: roughly a million German and Austro-Hungarian troops remained east, while Ukrainian grain arrived in disappointing quantities. Romanian oil offered another potential resource, although Romania’s settlement was separate from Brest-Litovsk. The treaty also gave the Allies further reason to resist German terms. Timing brought these gains and costs together. The transferred divisions could fight that spring; fuller returns from the east would take longer, and American arrivals were strengthening the Allies. Germany needed a quick victory from its temporary advantage, and its offensives failed to deliver one.

READ CHAPTER 11 — Treaty of Brest-Litovsk and WWI →

Germany had alternatives to the offensives it chose. It might have shortened its line, defended and sought a negotiated peace; the Hindenburg Line had resisted attacks well into 1918. But a settlement required terms acceptable to both sides. After Brest-Litovsk, German leaders had shown little willingness to relinquish gains such as Belgium, while American arrivals and financial support reduced Allied incentives to compromise. A narrower attack against the French or supply centers such as Amiens or Hazebrouck might have used German strength differently and perhaps prolonged the war, but it would still have faced Allied resources and growing American manpower. The actual offensives cost roughly a million casualties without forcing a decision. The U-boat campaign’s contribution to American entry and the eastern settlement had narrowed Germany’s choices before 1918. Victory is difficult to envisage under those constraints, though we cannot prove that every alternative would have failed.

Pershing argued for continuing at the time, and many of Germany’s enemies made the case later. An occupation might have made defeat undeniable to Germans, depriving the stab-in-the-back myth of its force and perhaps preventing the next war. That is a serious political gain to set against the choice made in 1918. But commanders then faced a still-cohesive retreating army and projected hundreds of thousands of casualties in another year of fighting. Their own populations were weary, influenza was burning through every unit and revolution was spreading. The armistice already secured the essential terms. Foch called it “the conditions of victory without the losses of storming Germany,” and most historians find that judgment defensible on 1918’s information. The later loss of the narrative inside Germany shows why legitimacy mattered too. The Allies had won materially, yet within five years their victory was being explained away there. Whether an invasion could have prevented that outcome remains uncertain; its human cost, potentially a million more graves, was much more immediate. The choice has no comfortable answer.

The case against Versailles begins with its combination of humiliation and surviving German power. War guilt, reparations and unilateral disarmament gave German governments a common grievance and gave Hitler a platform. German minorities supplied pretexts, while Russia’s exclusion and America’s departure deprived the order of guardians. The defense has evidence too. Versailles was milder than Brest-Litovsk, Germany’s own 1918 blueprint, and than partition in 1945. Weimar suffered from the Depression, elite contempt for the republic and deliberate myth-making, including the army’s “stab-in-the-back,” as much as from treaty clauses. Moreover, the treaty was being revised peacefully: reparations effectively ended by 1932, before Hitler mattered. Versailles made the peace vulnerable and weakened the coalition that might have defended it, making later destructive choices cheaper. It did not make 1939 inevitable. The 1920s show that reconciliation was possible; the 1930s show the cost of abandoning enforcement. A policy of punishment or reconciliation needs the resources to carry it through.

READ CHAPTER 14 — Treaty of Versailles →

Armies mattered most clearly in the east and south-east. Poland’s eastern frontier followed the battle line of 1920, Vilnius and Memel were seized by force, and Lausanne recognized the frontier won by Kemal’s army. Here treaties recorded results that soldiers had made possible. The claim fits the center and west less well. Versailles, Saint-Germain and Trianon drew frontiers that no army fought over in 1919, and the defeated states were too weak to resist. Diplomats did not make every decision alone there either. Plebiscites, votes in which local people chose their state much like referendums, settled Schleswig and Upper Silesia; new states had already been proclaimed in Prague and Zagreb. Drawing a border and keeping it were separate problems. Lines could be placed on paper, but those that lasted had force behind them or the consent of people living along them. The 1923 map was unstable because its borders outran the willingness to defend them—a gap governments of every era should consider before signing.
