4.2.1 War Plans

In the years preceding World War I, the European powers engaged in extensive military planning. This strategic preparation, particularly the Schlieffen Plan, played a pivotal role in the chain of events leading to the war, illustrating the profound impact of military strategies on historical developments.

The Context of Early 20th Century Military Strategies

The European Power Balance

  • Europe's major powers - Germany, France, Russia, and Austria-Hungary - were in a constant state of competition and mistrust.
  • Alliances such as the Triple Entente (Britain, France, Russia) and the Triple Alliance (Germany, Austria-Hungary, Italy) influenced military planning.

Technological and Tactical Developments

  • The advent of new technologies like machine guns, railways, and telegraphs revolutionised warfare.
  • There was a belief that offensive strategies would be key to quick victories, influenced by the rapid pace of previous conflicts like the Franco-Prussian War.

The Schlieffen Plan: A Comprehensive Analysis

Origins and Objectives

  • Conceptualised by German Chief of Staff Alfred von Schlieffen in 1905, the plan was a response to Germany's geopolitical dilemma of potential two-front warfare.
  • Its primary objective was to prevent a prolonged war on both eastern and western fronts by quickly defeating France and then focusing on Russia.

Operational Details

  • Route Through Belgium: The plan involved a sweeping movement through neutral Belgium to circumvent the strong French defences along the Franco-German border.
  • Right Wing Emphasis: The right wing of the German army, which was to swing through Belgium and northern France, was significantly stronger than the left wing holding against France's direct assault.
  • Time-Sensitive Execution: The plan required strict adherence to timing, with the fall of Paris envisaged within six weeks of the start of hostilities.

Flaws and Alterations

  • Logistical Challenges: The extensive movement of troops and supplies required was a logistical nightmare.
  • Modification by Moltke: Helmuth von Moltke, Schlieffen's successor, modified the plan, weakening the right wing due to concerns about violating Dutch neutrality and other logistical issues.

Impact of Military Plans on the Path to War

Mobilisation as a Catalyst

  • In an era where mobilisation was seen as a prelude to war, the intricate plans of the powers contributed to a tense atmosphere.
  • The rigid and time-sensitive nature of plans like the Schlieffen Plan meant that once mobilisation started, it was almost impossible to stop, pushing nations towards conflict.

Psychological and Political Dimensions

  • The existence of such detailed plans fostered a belief in the inevitability of war, influencing the mindset of military and political leaders.
  • Plans like the Schlieffen Plan were closely guarded secrets, leading to misperceptions and miscalculations by other powers.

Case Study: Russian Mobilisation

  • Russia's decision to mobilise in support of Serbia after the Austrian declaration of war against Serbia was a critical moment.
  • German perception of Russian mobilisation as an act of aggression, largely due to the existing war plans, prompted Germany to declare war on Russia.

The Schlieffen Plan in Action: From Theory to Reality

The Outbreak of War

  • Germany's implementation of the Schlieffen Plan began with the invasion of Belgium on August 4, 1914, leading Britain to declare war on Germany.
  • The violation of Belgian neutrality, as necessitated by the plan, brought the British Empire into the conflict, significantly altering the war's scope.

Operational Challenges

  • The logistical complexities, resistance by Belgian forces, and the rapid mobilisation of French and British troops hampered the plan's execution.
  • The Battle of the Marne in September 1914 marked the failure of the Schlieffen Plan, leading to a prolonged and gruelling trench warfare on the Western Front.

The strategic military planning of the early 20th century, epitomised by the Schlieffen Plan, had far-reaching consequences. These plans, designed for a swift and decisive victory, ultimately plunged Europe into a protracted and devastating war. The rigid mobilisation schedules, the psychological commitment to the plans, and the failure to adapt to changing circumstances on the ground demonstrate the complex interplay between military planning and the course of history. This case study provides a crucial insight into the causes of World War I, highlighting the role of military strategies in shaping global events.

FAQ

The Schlieffen Plan took into account Russia's military capabilities by assuming a slower Russian mobilisation process. The Plan was predicated on the idea that Germany could defeat France quickly, within six weeks, before Russia could fully mobilise its forces. Therefore, only a minimal German force was initially allocated to the Eastern Front against Russia. This assumption was a critical part of the Plan's strategy, allowing the majority of German forces to concentrate on the Western Front. However, this underestimation of Russia's mobilisation capacity and the subsequent diversion of forces to the Eastern Front upon Russia's faster-than-expected mobilisation were among the key factors that led to the Plan's failure.

Yes, significant changes were made to the Schlieffen Plan between its initial conception by General Alfred von Schlieffen and its eventual execution in 1914. One major alteration was made by Schlieffen's successor, Helmuth von Moltke the Younger, who reduced the strength of the right wing of the army – the wing that was supposed to sweep through Belgium and encircle Paris. Moltke redirected these forces to strengthen the left wing against a potential Russian attack, fearing a quicker Russian mobilisation than initially anticipated. Additionally, Moltke altered the route of the advance, avoiding the Netherlands to maintain their neutrality, which impacted the logistical and operational aspects of the Plan. These changes arguably weakened the Plan’s effectiveness and contributed to its ultimate failure.

Railway networks played a crucial role in both the planning and execution of the Schlieffen Plan. The Plan was heavily reliant on Germany's advanced railway system for the rapid mobilisation and transportation of troops and supplies. Schlieffen meticulously planned the troop movements, scheduling trains down to the minute to ensure the swift and efficient movement of forces to the Western Front. This reliance on railways was a testament to the industrial age's impact on warfare, where logistical capabilities were as crucial as military tactics. However, during execution, the logistical challenges of moving large numbers of troops and equipment quickly became apparent, contributing to delays and the eventual stalling of the German advance. The railways, while essential for mobilisation, also imposed rigid timetables that were difficult to adjust once the war commenced.

The Schlieffen Plan had a significant impact on diplomatic relationships in Europe prior to World War I. It heightened tensions, especially between Germany, France, and Belgium. The Plan's reliance on invading neutral Belgium was particularly problematic, straining Germany's relationship with Britain, which had a treaty obligation to defend Belgian neutrality. Furthermore, the secretive nature of the Plan contributed to an atmosphere of distrust and paranoia among the European powers, as they were all developing similar offensive strategies. This lack of transparency and the aggressive nature of the Plan exacerbated fears and contributed to the formation of rigid alliance systems, which further polarised the European powers.

The Schlieffen Plan and France's Plan XVII were fundamentally different in their strategic objectives and operational approaches. The Schlieffen Plan, crafted by Germany, aimed to quickly knock France out of the war through a massive flanking movement via Belgium, avoiding a protracted two-front war. In contrast, France's Plan XVII focused on a direct offensive into Alsace and Lorraine, territories lost in the Franco-Prussian War. While the Schlieffen Plan emphasised speed and surprise, relying on a sweeping movement through neutral Belgium, Plan XVII was more conventional, prioritising a head-on confrontation and the recapture of lost territories. These contrasting strategies reflected the differing military doctrines and historical grievances of the two nations.

Practice Questions

Evaluate the impact of the Schlieffen Plan on the early stages of World War I.

The Schlieffen Plan significantly influenced the early stages of World War I, primarily by accelerating the conflict's escalation. Designed for a quick victory over France, its execution led to Germany invading Belgium, thus violating Belgian neutrality. This action directly caused Britain to enter the war, transforming a continental conflict into a broader war involving the major European powers. The Plan's failure at the Battle of the Marne, due to logistical challenges and underestimation of the Allied response, resulted in a prolonged stalemate and trench warfare on the Western Front. This shift from rapid offensive to entrenched positions defined the character of World War I, demonstrating the Plan's profound but unintended consequences.

Discuss how military planning, particularly the Schlieffen Plan, contributed to the onset of World War I.

Military planning, exemplified by the Schlieffen Plan, was instrumental in the onset of World War I. The Plan's essence was to avoid a prolonged two-front war by quickly defeating France. Its rigid timetable and the necessity of violating Belgian neutrality made diplomatic solutions less feasible, as Germany was committed to its execution upon mobilisation. This inflexibility in planning created a domino effect, where mobilisation was perceived as an act of war, prompting immediate military responses from other powers. Thus, the Schlieffen Plan, with its aggressive strategy and precise timing, escalated regional tensions into a full-scale war, underscoring the critical role of military preparations in the war's genesis.
