An unimagined tragedy

The First World War started in 1914 and ended in 1918. It was an unimagined tragedy as few people really understood how industrialization would change warfare. Only the Russo-Japanese War, which started in 1904 and ended in 1905, offered any glimpse of what mechanized weapons could do. Most of the main combatants in the First World War were entering a new and much deadlier battleground. The main countries involved were Britain, France, Germany, Austro-Hungary, the Ottoman Empire, and later Italy and the United States.

War plans

Every country thought it was well prepared for the First World War. In the past, ancient and medieval generals planned the movement of their armies only after wars began. The First World War had been planned out and war-gamed by generals for decades prior in some countries. Most military leaders understood that the pace of warfare had changed. Railroads were a game-changer that would make everything happen faster. In order to get an advantage, or to get anywhere first, plans had to be established and followed carefully.

The most important plan in this war was the German Schlieffen Plan, first proposed in 1891. It was based on the belief that there would be a war between Germany on the one hand and both Russia and France on the other. Fighting both opponents at once, on two sides of Germany, was risky. But German strategists also saw that France, with its shorter distances and more modern railways, could get an army to Germany before Russia. Vast, under- industrialized, Russia would take time to mobilize.

The Germans devised a plan to rapidly invade France and knock them out of the war first. The Germans would then turn around and fight Russia. The only problem was that the fastest way to knock out France was to go through Belgium, and Britain had promised to protect Belgium. German planners hoped the British wouldn’t really come in to defend this tiny country.

The Schlieffen Plan went into operation almost immediately when the war began. The conflict started following the assassination of the Austro-Hungarian Archduke Franz Ferdinand on June 28, 1914. He was killed by Gavrilo Princip, allegedly on behalf of Serbia. This led to the Austro-Hungarian Empire declaring war on Serbia.

Russia joined the war on Serbia’s side, while Germany had to join their Austro-Hungarian allies in the war against Russia. Just as the Schlieffen Plan predicted, France came in on the side of their Russian allies.

From mobility to trenches on the Western Front

The speed of mobilization meant that the first big battles of the war would be fought in the west. The German army followed the Schlieffen Plan and invaded Belgium and France. On August 14, battles erupted along the Franco- German frontier. The French were pushed back as the well-designed Schlieffen Plan went into effect. Unfortunately for the Germans, the decision to invade Belgium did bring Britain into the war. British forces joined the French, putting into effect the alliance known as the Triple Entente.¹ All along the Western Front, armies made up of British, Belgian, and French soldiers were slowly pushed back towards the French capital of Paris. However, the efforts turned out to be too slow. French reinforcements were rushed to the front. By September 5, they were pushing back in a vast counterattack known as the Battle of the Marne.

As the Germans retreated from around Paris, the nature of the conflict began to change. It became clear that defenders had a big advantage over attackers, especially when they were dug into the ground, or “entrenched.” Modern weapons, especially machine guns, could put out vast amounts of bullets very quickly. Attacking—especially across open ground—now meant increased casualties for the attackers. The only way to overcome a well-placed defense was with artillery firing huge shells. But defenders who dug into the ground, building trenches, were safer against artillery. Slowly the whole battlefront in the west became a series of trenches leading from Switzerland to the sea.

The war beyond the Western Front

While the Western Front was becoming bogged down, the mighty Russian Empire finally got its armies to the front lines. At first, the huge Russian armies were pretty effective against the Austro-Hungarian forces. Together with their allies in Serbia, they defeated the Austro-Hungarians in several small battles. However, the two Russian armies facing the Germans were divided. Part of the problem was bad communications, and another part was that their generals hated each other. At the end of August 1914, one army was surrounded by German forces at Tannenberg and forced to surrender. The Russians had been dealt a huge blow, but they remained in the war.

Meanwhile, new countries had joined the war. Two of the most important were the Ottoman Empire and Italy. The Ottomans entered the war on the German and Austro-Hungarian side. Together, they formed the Central Powers. The Ottomans hoped that they could reclaim territory lost to Russia in previous wars. However, their first attacks into Russia were not successful, and they soon found themselves embroiled in battles against British forces in Egypt and Mesopotamia. Italy, similarly, entered the war hoping to win back territory—land that the Austro- Hungarian Empire claimed. They, too, found their first attacks unsuccessful and soon bogged down into a slow, difficult war in the Alps mountains.

Already, the war was extended far beyond Europe. Japan entered the conflict on the side of its ally, Great Britain, within the first week of the war. Their modern navy quickly conquered German colonies in China (in Qingdao, or Tsingtao) and the Pacific (Mariana, Caroline, and Marshall Islands). In Africa, meanwhile, the German colonies were also under attack. British and French forces quickly conquered German Togo and Cameroon in West Africa, while British South African forces occupied German South-West Africa in 1915. The German armies in East Africa held out until the end of the war. In almost all cases, most of the fighting was actually done by African soldiers.

Attempting to break the stalemate

By the middle of 1915, the war was sort of stuck. In most places, modern weapons meant that there could be little movement. The enormousness of the armies and total mobilization of economies meant that it was difficult to turn even a victorious battle into a major event.

Along the Western Front, a series of small attacks inevitably ended in terrible failure, and the armies settled down in exhaustion. The addition of gas weapons made movement even more difficult, and the armies built better and better bunkers and defenses to stop attackers. One strategy was to make the attacks even bigger. The result was just more casualties. Beginning in February 1916, for example, the Germans tried to grind the whole French army to death by attacking the fortified line at Verdun. They wanted a long battle, forcing the French to send unit after unit replacing defeated soldiers. In the end, the French lost about 400,000 to death or injury in this battle, and the Germans about 350,000. In July 1916, a largely British force tried to break the German lines at the Battle of the Somme. They suffered more than half a million casualties, including 150,000 dead. German losses were similar.

There were also attempts to provoke a naval battle to shift the balance of the war. The German fleet sailed out to challenge the British Home Fleet at the end of May 1916. The resulting Battle of Jutland didn’t resolve anything. Both fleets remained in existence, even though the German fleet didn’t sail out again during the war.

Another strategy for breaking the stalemate was to knock one opponent out of the war. The British, for example, thought they could break down the Ottoman Empire by occupying the capital of Constantinople, which later came to be known as Istanbul. They sent a force—mainly Australian and New Zealand troops—to land at a place called Gallipoli, along the coast near Constantinople. This attack also failed and left 250,000 casualties on either side.

Both sides also tried to damage each other through economic means. The British fleet tried to stop any goods from going into Germany, and largely succeeded, although very slowly. The Germans tried to use U-boats (submarines) to strangle the British economy. This strategy was effective for a while, but convoys and new technology slowly diminished the kill rate of the U-boats.

Russia and the Americans

Eventually, the Central Powers did manage to knock out one opponent. Russian armies had been suffering some bad defeats throughout 1916 and the Russian economy was in shambles because of the war. This helped to create the conditions for the Russian Revolution. At first, the revolutionary government stayed in the war, but after the communist Bolsheviks took power, Russia bowed out.

This should have radically transformed the conflict to the benefit of Germany and its allies. However, just as the Russians were leaving, the United States was entering the conflict. The main cause was German unrestricted submarine warfare, which affected American shipping. German attempts to win Mexican allies and other issues also helped convince the United States to declare war.

American troops began to arrive in the summer of 1917. The American troops were inexperienced, but given the exhaustion of every other army in the war, they injected a needed morale boost in their allies.

By late 1918, then, things were beginning to look bad for the Central Powers. Their armies were in retreat almost everywhere. Britain and local allies pushed the Ottoman forces out of Mesopotamia and Arabia in September. The Austro-Hungarians were defeated by the Italians in an important battle in June. Within a few months, many of their subject peoples—Croats, Slovenes, Serbs, Poles—were declaring independence. German soldiers held on as best they could but faced terrible economic conditions at home as the British blockade tightened. In late October, parts of the navy began to revolt, and a new government came to power, determined to end the war. On November 11, an armistice was signed between the victorious Triple Entente and their allies on the one hand, and Germany on the other.

Conclusions

A single article tells the history of the First World War like a rapid whirlwind. In fact, it was a terrible four-year slog of mud and death. All of the plans for quick victories looked like a bad joke from the viewpoint of November 1918. Everyone hoped it would be “the war to end all wars”, but it was not.

1 By treaty, the Franco-Russian-British Triple Entente had existed since 1907. The British entry into the war meant that it was actually in operation.
