Topics in The First World War 1914-1918
The Two Opposing Sides
- The war was fought between two main groups: the Allied/Entente Powers and the Central Powers.
- The Allied Powers included Britain and her empire (India, Australia, Canada, New Zealand), France, Russia (left December 1917), Italy (joined May 1915), Serbia, Belgium, Romania (joined August 1916),
- The Central Powers included Germany, Austria-Hungary, Turkey (joined November 1914), and Bulgaria (joined October 1915).
The Western Front: Stalemate and Trench Warfare
- The German advance into Belgium was delayed by unexpectedly strong Belgian resistance — it took over two weeks to capture Brussels.
- This delay allowed British forces (British Expeditionary Force) to land and kept the vital Channel ports free.
- The Battle of the Marne (September 1914) was a turning point — French forces under Joffre drove the Germans back to the River Aisne, where they dug trenches.
The Eastern Front and Other Theatres
- Russia mobilized faster than Germany expected but then made the strategic error of invading BOTH Austria AND Germany simultaneously.
- Russians were successful against Austria (occupied Galicia) but suffered devastating defeats against Germany at Tannenberg (August 1914) and the Masurian Lakes (September 1914) — driven out of Germany
- By end of 1914, one-third of Russia's 6.25 million mobilized men had no rifles — a catastrophic shortage.
The War at Sea
- Both sides expected a major sea battle (like Trafalgar) between Dreadnought fleets, but both were cautious about risking their main fleets.
- Germany had only 16 latest Dreadnoughts against Britain's 27, making them reluctant to seek a direct confrontation.
- The THREE Allied naval aims: (1) Blockade the Central Powers to starve them; (2) Keep trade routes open to prevent the Allies from starving; (3) Transport and supply British troops via Channel ports.
