What Did The Policy Of Unrestricted Submarine Warfare Refer To

The chilling echo of torpedoes ripping through the hull of a ship, the agonizing cries of those caught in the icy depths – these are the haunting sounds associated with unrestricted submarine warfare. It's a term that evokes images of stealthy underwater predators unleashing devastation on unsuspecting vessels, a strategy employed with devastating effect, and often with dire moral consequences.

Imagine yourself as a civilian passenger aboard a seemingly safe merchant ship, only to be suddenly confronted with the terrifying reality of an incoming torpedo. Your life, your journey, all abruptly threatened by a policy that prioritizes military gain over the sanctity of human life. This is the stark reality that lay at the heart of unrestricted submarine warfare, a policy that dramatically shaped the course of World War I and beyond.

Unrestricted Submarine Warfare: A Definition

At its core, unrestricted submarine warfare is a type of naval warfare where submarines are permitted to attack any vessel, including merchant ships, passenger liners, and neutral ships, without warning. This deviates sharply from the traditional cruiser rules of naval warfare, which mandated that warships had to warn civilian vessels before attacking, allowing passengers and crew to evacuate to safety. Unrestricted submarine warfare throws these conventions overboard, prioritizing surprise and maximum damage above all else.

• The Breach of Cruiser Rules: Traditional naval warfare distinguished between combatants and non-combatants. Warships were expected to give warning before attacking merchant vessels, allowing passengers and crew to disembark. Unrestricted submarine warfare disregarded this, making any ship a potential target.
• The Element of Surprise: Submarines, by their very nature, rely on stealth and surprise. Unrestricted warfare maximized these advantages, allowing submarines to strike without warning, maximizing the chances of a successful attack.
• The Escalation of Conflict: The policy inevitably led to the escalation of conflict, drawing neutral nations into the war as their ships and citizens became victims of submarine attacks.

Historical Context: The Rise of the U-Boat

To understand the significance of unrestricted submarine warfare, it's essential to delve into the historical context that birthed this controversial strategy:

• The Naval Arms Race: In the years leading up to World War I, a fierce naval arms race gripped Europe, particularly between Great Britain and Germany. Both nations poured vast resources into building powerful battleships, dreadnoughts, in an attempt to establish naval dominance.
• The Limitations of Surface Fleets: The advent of the submarine, or U-boat (Unterseeboot in German), presented a new dynamic. While surface fleets were powerful, they were also expensive to build and maintain. Submarines, on the other hand, offered a relatively affordable means of challenging British naval supremacy.
• Germany's Strategic Dilemma: As World War I erupted, Germany faced a significant disadvantage. The British Royal Navy imposed a strict naval blockade, cutting off vital supplies of food, raw materials, and war materials. Germany sought a way to break this stranglehold, and the U-boat seemed to offer a glimmer of hope.

Germany's Gamble: The First Phase (1915)

Desperate to counter the British blockade, Germany first implemented a policy of unrestricted submarine warfare in February 1915. The logic was simple: if Germany could sink enough British merchant ships, it could cripple the British economy and force them to negotiate peace.

• The War Zone Declaration: Germany declared the waters around the British Isles a war zone, warning neutral ships that they risked being sunk.
• The Lusitania Disaster: The policy quickly backfired when, on May 7, 1915, the German submarine U-20 torpedoed and sank the British passenger liner Lusitania. The sinking resulted in the deaths of nearly 1,200 people, including 128 Americans. This event sparked international outrage, particularly in the United States.
• American Pressure: The sinking of the Lusitania brought the United States to the brink of war. President Woodrow Wilson strongly condemned the German policy and demanded that Germany abandon unrestricted submarine warfare.
• Temporary Suspension: Facing immense pressure from the United States and fearing American entry into the war, Germany temporarily suspended unrestricted submarine warfare in September 1915.

The Unholy Resurrection: 1917 and the Zimmerman Telegram

Despite the initial suspension, the allure of unrestricted submarine warfare proved too strong for Germany to resist. By 1917, Germany was facing increasing economic hardship due to the continuing British blockade. Military leaders argued that only unrestricted submarine warfare could break the stalemate on the Western Front and force the Allies to surrender.

• The Calculation of Risk: German leaders calculated that even if unrestricted submarine warfare brought the United States into the war, they could defeat the Allies before American troops could arrive in significant numbers.
• The Resumption of Unrestricted Warfare: On February 1, 1917, Germany resumed unrestricted submarine warfare. The consequences were swift and devastating.
• The Zimmerman Telegram: Compounding the impact of unrestricted submarine warfare was the Zimmerman Telegram, a secret communication from the German Foreign Office to the German ambassador in Mexico. The telegram proposed a military alliance between Germany and Mexico if the United States entered the war against Germany. In return, Mexico would receive financial aid and the territories of Texas, New Mexico, and Arizona, which it had lost to the United States in the 19th century.
• American Entry into World War I: The Zimmerman Telegram, intercepted and decoded by British intelligence, was released to the American public. This, combined with the sinking of American ships by German U-boats, galvanized public opinion in favor of war. On April 6, 1917, the United States declared war on Germany, fundamentally shifting the balance of power in favor of the Allies.

The Impact and Consequences

The policy of unrestricted submarine warfare had a profound and lasting impact on World War I and the subsequent course of history:

• Increased Casualties: The policy resulted in the deaths of thousands of civilians and merchant sailors. It transformed the seas into a deadly battleground, undermining the traditional distinction between combatants and non-combatants.
• Economic Disruption: Unrestricted submarine warfare caused significant disruption to international trade and supply lines, exacerbating economic hardship in both Allied and neutral countries.
• American Intervention: As described above, the policy directly led to the United States entering World War I, a pivotal moment that ultimately decided the outcome of the conflict.
• Moral Outrage: The policy sparked widespread moral outrage around the world, solidifying Germany's image as an aggressor and undermining its legitimacy on the international stage.
• The Washington Naval Treaty: In the aftermath of World War I, the Washington Naval Treaty of 1922 sought to limit naval armaments and establish rules of conduct for submarine warfare. While the treaty did not explicitly ban submarines, it prohibited the sinking of merchant ships without warning and required submarines to provide for the safety of passengers and crew. These regulations were designed to prevent the recurrence of the atrocities committed during World War I.

The Debate: Military Necessity vs. Moral Imperative

The policy of unrestricted submarine warfare remains a subject of intense debate among historians and ethicists.

• Arguments for Military Necessity: Proponents of the policy argue that it was a necessary measure for Germany to break the British blockade and prevent economic collapse. They claim that in times of war, extreme measures are sometimes justified to achieve strategic goals.
• Arguments Against Moral Justification: Opponents of the policy contend that it was a clear violation of international law and morality. They argue that deliberately targeting civilian ships and killing innocent people can never be justified, regardless of the circumstances. The principle of distinction is central to just war theory, which necessitates differentiating between combatants and non-combatants. Unrestricted submarine warfare obliterates this distinction.
• The Question of Proportionality: Another key aspect of just war theory is proportionality, which asserts that the harm caused by a military action should be proportional to the military advantage gained. Critics argue that even if unrestricted submarine warfare provided a tactical advantage, the immense human cost far outweighed any potential benefits.

Lessons Learned (or Not?)

The legacy of unrestricted submarine warfare is complex and troubling. While the Washington Naval Treaty attempted to regulate submarine warfare, these rules were often ignored during World War II. Both Germany and the United States engaged in practices that blurred the lines between legitimate targeting and indiscriminate attacks on civilian vessels.

• The Enduring Temptation: The temptation to employ unrestricted submarine warfare remains a persistent threat. The strategic advantages of surprise and the potential to cripple an enemy's economy are powerful incentives.
• The Importance of International Law: The history of unrestricted submarine warfare underscores the importance of international law and the need for clear rules of engagement. Without these safeguards, the potential for atrocities and the escalation of conflict increases dramatically.
• The Moral Responsibility of Commanders: Ultimately, the decision to employ unrestricted submarine warfare rests on the shoulders of military commanders. They must weigh the potential benefits against the inevitable human cost and consider the long-term consequences of their actions.
