WWI: Course and New Weapons
FoundationWWI's main front was the Western Front: trench stalemate across 'no man's land', with new weapons (machine guns, gas, tanks, aircraft, submarines) causing unprecedented casualties. US entry in 1917 tipped the balance; Germany surrendered in November 1918.
- Western Front stalemate; defence dominated
- New weapons: machine guns, gas, tanks, U-boats
- 1917 US in, Russia out → 1918 Armistice
§Text Passage
1After the war began, Germany followed the Schlieffen Plan in search of a quick victory, striking at France through Belgium. But the Battle of the Marne in September 1914 halted the advance; both sides dug trench lines along the Western Front that barely moved for years, and the war of quick decision became a long war of attrition.
2Industrial technology poured onto the battlefield and produced a generation of new weapons: machine guns made frontal charges ruinous, Germany first used poison gas in 1915, tanks went into action at the Somme in 1916, aircraft scouted and bombed, and German U-boats waged unrestricted submarine warfare. Yet the new weapons were few at first and mostly favoured the defence, so the deadlock held.
31917 proved the turning point: Germany's resumption of unrestricted submarine warfare sank American ships and brought the United States into the war in April, adding fresh troops and vast industrial capacity to the Allies; in the same year Russia was overtaken by the February and October Revolutions, and the new government made peace with Germany. The balance of forces tipped toward the Allies.
4Germany's spring offensive of 1918 came close to Paris but broke through nothing; American troops arrived in ever greater numbers, the Allies counter-attacked in the autumn, and with food shortages, naval mutiny and revolution at home, the Kaiser abdicated. Germany signed the Armistice on 11 November. The cost was some seventeen million dead and the collapse of four empires.

Opposing trenches with 'no man's land' between — attacks cost heavily.
The deadly strip between opposing trenches.
Whole economies, industries and populations mobilised for war.
Signed 11 Nov 1918 — ending WWI.
Germany's plan for a quick victory — beat France fast, then turn on Russia; it stalled at the Battle of the Marne in 1914.
The main front in France and Belgium, where the armies faced each other from trenches for nearly four years.
Germany's declared policy of sinking, without warning, all ships bound for Britain, including neutral ones — it brought the US into the war.
A new weapon first sent into battle in 1916; it crushed wire and crossed trenches, later key to breaking the stalemate.
3Step by step Steps
- Opening & stalemateAfter the war began, Germany followed the Schlieffen Plan in search of a quick victory: it would march through Belgium to strike France first, defeat it within weeks, and then turn on the more slowly mobilising Russia. But the German advance outran its supplies, and at the Battle of the Marne in September 1914 the British and French armies halted it; the plan had failed. Both sides then dug trench lines along the Western Front that barely moved for years, producing a long trench stalemate and turning the war from a short campaign into a war of attrition.
- New weaponsDuring the war, industrial technology was applied to the battlefield on a massive scale and produced many new weapons. Machine guns fired with such intensity that frontal charges cost terrible casualties; Germany first used poison gas in 1915, opening the age of chemical warfare; tanks went into action for the first time at the Somme in 1916, crushing wire and crossing trenches; aircraft scouted and bombed, while German U-boats waged unrestricted submarine warfare, sinking merchant ships bound for Britain. Yet the new weapons were few at first and mostly favoured the defence, so the deadlock endured.
- Turning points1917 was the turning point of the war. Early in the year Germany resumed unrestricted submarine warfare, sinking ships bound for Britain without warning, including American vessels; the United States therefore declared war in April, bringing fresh troops and vast industrial capacity to the Allies. In the same year Russia was overtaken by the February and then the October Revolution, and the new Soviet government made peace with Germany, leaving the war by the year's end. America's entry and Russia's exit greatly altered the balance of forces, and the scales tipped toward the Allies.
- EndIn early 1918, freed by Russia's withdrawal, Germany shifted its armies west and launched a spring offensive that came close to Paris but failed to achieve a decisive breakthrough. American troops then arrived in Europe in ever greater numbers, and in the autumn the Allies counter-attacked, driving the Germans back step by step. At home Germany faced food shortages, war-weariness, naval mutiny and spreading revolution, and Kaiser Wilhelm II was forced to abdicate. On 11 November the new German government signed the Armistice, and the First World War was over.
- CostThe cost was immense: about 17 million people died and 20 million were wounded, most of them men in the prime of life. The German, Austro-Hungarian, Russian and Ottoman empires collapsed one after another and the map of Europe was redrawn; the belligerents were left deep in debt and their economies badly damaged. A whole generation of young Europeans perished at the front, and the survivors' shaken faith in Western civilisation led historians to call them the 'Lost Generation'. Europe's position at the centre of the world began to weaken from then on.
- The eastern and other frontsThe fighting was by no means confined to the Western Front. In the east, Russian armies fought the German and Austrian forces for years and were crushed at Tannenberg in 1914. In the south, the British and French Gallipoli landings of 1915, meant to open a sea route to the Black Sea, failed with heavy losses; Serbia and Romania were overrun in turn by the Central Powers. The colonies supplied large numbers of men and resources, and the war reached the Middle East and Africa as well. Fighting on so many fronts exhausted the powers' resources faster and deepened the destruction further.

5Worked example Example
Why did trench warfare stalemate for four years?
- Machine guns + artillery made frontal attacks suicidal
- Roughly equal forces; defenders had the edge
- Any breakthrough was plugged by reserves
- New tech (tanks) was few and immature early on
- Result: a war of attrition, deadlocked for years
- Answer: Because defence outmatched attack: machine guns, barbed wire and artillery made charges ruinous, the two sides were roughly equal in strength, and every breakthrough was plugged by reserves; tanks were still few and immature, so the war became one of attrition, deadlocked for nearly four years. Only in 1918 — mature tank tactics, US troops arriving, German collapse at home — was the deadlock broken. Answer by explaining 'defence stronger than attack' first, then the three factors that broke it.
