4. Journal #13 “Serbia was right in wanting to expand, Austria in wanting to survive. Germany was right in fearing isolation, Great Britain in fearing German power. Everyone was right. And everyone was wrong, for no one foresaw what war would mean, either in terms of costs or of consequences. All were sinners, all were sinned against.” - Joachim Remak Who was responsible for starting WWI?

5. 1914-1915: Illusions and Stalemate Illusions fed enthusiasm for the war in 1914 – Belief that the war would only last a few weeks Home by Christmas (historical trend in Europe, American Civil War overlooked) – War could not last for more than a few months without destroying a nation’s economy – Fatal Attraction to a “glorious adventure” – Redemption: national rebirth based on self- sacrifice, heroism, and nobility

6. The Western Front The Schlieffen Plan Called for Germany to quickly crush France before Russia was fully ready Plan had many faults: – more resistance in Belgium; German advances delayed – Russia mobilized faster – Britain met German forces in northern France – France attacked in the south

7. Germany invaded France through Belgium (a neutral nation) Britain brought into war once Germany entered Belgium, Britain pledged to defend Belgium’s neutrality August 4, 1914 Britain declares war on Germany

9. German offensive stalled in September with France and Britain taking stand along Marne River The First Battle of the Marne was perhaps the single most important event of the war – This ended hopes of quick victory for Germany – Ruined Schlieffen Plan – Germany was pushed back

10. By fall 1914 Britain and France stabilized Germany along the western front Nov. 1914: neither side could deal final blow – settled down to trench warfare – for next 3 years: fighting only preserved stalemate w/ many casualties

14. Stalemate

15. Nations Take Sides Central Powers Germany Austria-Hungary Bulgaria (joins later 11/1914) Ottoman Empire (joins later 10/1915) Allied Powers (Allies) Great Britain France Russia Japan Italy (1915)

16. Western Front Battles Verdun and Somme Most costly battles of the war, exemplified “war of Attrition” Trench Warfare

17. Verdun (Feb–Dec 1916) Begun by Germany to end stalemate Casualties – nearly a million (fairly equal on both sides) Result: Germany advanced about four miles

18. Somme (in northern France) July 1, 1916 – November 1916 Begun by Allies to draw Germans out of Verdun Casualties (one of the bloodiest battles of war, ever): first day=20,000 British soldiers dead Result: Allies had gained five miles of bloody mud from the Germans at a cost of 600,000 men: 400,000 British Imperial, and 200,000 French casualties (BBC)
