World War 1: Fighting the War
9. The Time of World Wars
Slide 1 - Diapositive
What is this lesson about?
During World War I, industrially made weapons were used on huge scale for the first time in history. Aeroplanes, poison gas, and the tank were used, but generals on both sides still employed outdated tactics. They did not seem to care about the loss of lives. Millions of soldiers died in useless assaults, just to conquer a few kilometres. The war changed in 1917, when the USA joined on the side of the Allies and when Russia signed a ceasefire with Germany. After four years of fighting, the war ended in 1918.

Introduction
For years, armies on the Western Front were locked in mortal combat. Millions of soldiers fought under terrible conditions in the trenches. During the war, new weapons were invented and used. Nevertheless, the balance of power was not much disrupted until the decisive year of 1917.

New weapons
Because of the combination of militarism and the industrial revolution, huge advances were made in the production of weapons; these were developed in an attempt to get through to enemy trenches. An example for this is the aeroplane. They were mainly used for scouting, but armed with machine guns and small bombs they could also inflict damage on enemy soldiers and supplies. Many air battles were fought, but the aeroplane did not play an important role in warfare until World War II.
Another modern weapon was the submarine, such as the U-Boat. This was not a new invention but the Germans were the first to use submarines on a large scale to challenge the superior British naval fleet. In determined attempt, they tried to stop every ship that sailed towards England.
The First World War is also infamous for the use of chemical weapons. Gasses such as chlorine, tear gas and mustard gas were put in bombs and shot into enemy trenches. The gasses burned eyes, nose and lungs and caused suffocation. Attacks using gas did not cause many deaths compared to other weapons, but the psychological effect of its use was great.

Slide 17 - Question de remorquage
Despite having new and destructive weapons at their disposal, the strategies and mindset of the generals did not change much. They expected to fight in an oldfashioned way. For example, at the outbreak of the war, the French soldiers went to battle wearing traditional blue coats and red trousers, which made them highly visible and thus easy targets. Horses were used at the start of the war and generals ordered massive attacks on enemy trenches, even though the enemy used machine guns, resulting in the deaths of millions.

Battles at Verdun and the Somme
The best examples of the senseless slaughter took place at the Battle of Verdun and the Somme Offensive. In 1916, both Germany and the Allies prepared an attack to break through the stalemate. The Germans were first to launch a wave of attacks. On 21st February, they charged the French defences at Verdun, but the French resisted heavily. For ten months, the battle went on until the Germans called off the attack. It is estimated that about 350,000 soldiers died at the Battle of Verdun.

B

C
few casualties,
no breakthrough
D
few casualties, and stalemate is broken.
Slide 22 - Quiz
The massacres got worse when French and British troops raised their armies to full strength. At the River Somme, they assaulted the German trenches with blunt and overwhelming force. On the first day of the attack the British lost 57,450 men, which made it the darkest day in the history of the British army. The British deployed their new secret weapon during the battle of the Somme: the tank. This armoured vehicle ran on caterpillar tracks and was designed to cross trenches and break through barbed wire.
The appearance of the tank on the battlefield was spectacular, but could not bring an end to the war: tanks were only used in small numbers, had poor mobility and mechanical problems. After the Somme Offensive, the Allies had taken more than ten kilometres of land; this at the cost of more than a million soldiers’ lives makes it one of the bloodiest battles in human history.

1917: a decisive year
In 1917, two significant events changed the course of the war. German U-Boats kept attacking unarmed passenger and merchant ships. In 1915, they torpedoed the British ocean liner ‘The Lusitania’. It sank immediately and 1,200 people lost their lives, among them 128 Americans. This led to massive anti-German sentiment in the United States. Two years later, a letter was intercepted, showing that the Germans tried to make an alliance with Mexico to attack the United States. On 6th April 1917, the United States Congress voted to join the Allies in the war.

Another major event happened in Russia during February 1917. Due to great poverty and inequality in this huge empire, a revolution took place. The German secret service made use of the unrest there: they sponsored the revolutionary Lenin to take control of the Russian government. When Lenin came to power in October, he signed a peace treaty with Germany: the Treaty of Brest-Litovsk. Germany and Russia were no longer enemies. (You will learn more about the Russian Revolution in the next chapter ). Now the Germans could send all their troops to the Western Front.

The end of a total war
World War I was the first total war, which means that everything in a country is focused on winning the war. Factories constantly worked to make weapons; food and fuel were rationed so it could be sent to the front, and a constant stream of propaganda was broadcast to keep the spirits up on the home front. Men had to fight, so women had to replace them in the factories. A country began to run as if it was a machine. But total war was not enough for the Central Powers: from the moment that the United States joined the conflict, the end of the war became a real prospect. More than a million fresh military personnel and innumerable supplies were shipped from the USA to the Allies in Europe, which provided a big moral boost. Germany and the other Central Powers could not compete with the Allies once the Americans joined them. Besides that, there was now discontent in Germany. In 1918, the Germans at last surrendered. At 11am on 11th November (‘the eleventh hour of the eleventh day of the eleventh month’), Germany signed an armistice in railway carriage No. 2419D, in Compiègne Forest, close to Paris. The Great War had come to an end. The Allies were victorious.
