Detailed Information

28 June 1914 Assassination of Franz Ferdinand The Balkan states of Bosnia and Herzegovina, had been annexed from Turkey and taken into the Austro-Hungarian Empire. This was strongly resented by many Serbs and Croats and a nationalist group, The Black Hand, was formed.

Archduke Franz Ferdinand of Austria, and his wife, had decided to inspect Austro-Hungarian troops in Bosnia. The date chosen for the inspection was a national day in Bosnia. The Black Hand supplied a group of students with weapons for an assassination attempt to mark the occasion.

A Serbian nationalist student, Gavrilo Princip, assassinated the Austrian Archduke Ferdinand and his wife, when their open car stopped at a corner on its way out of the town.

28 July 1914 Austria declared war on Serbia The Austrian government blamed the Serbian government for the assassination of Franz Ferdinand and his wife and declared war on Serbia.

Although Russia was allied with Serbia, Germany did not believe that she would mobilise and offered to support Austria if necessary.

However, Russia did mobilise and, through their alliance with France, called on the French to mobilise.

4 Aug 1914 British declaration of war Germany did not withdraw from Belgium and Britain declared war on Germany.
Aug 1914 Battle of Tannenberg The Russian army marched into Prussia. However, because of the differences in railway gauge between Russia and Prussia it was difficult for the Russians to get supplies through to their men. The Germans, on the other hand, used their railway system to surround the Russian Second army at Tannenberg before it's commander could realise what was happening. The ensuing battle was a heavy defeat for the Russians with thousands of men killed and 125,000 taken prisoner. Although the Germans won the battle, 13,000 men were killed.

late 1914 Early stages of the war The German advance through Belgium to France did not go as smoothly as the Germans had hoped. The Belgians put up a good fight destroying railway lines to slow the transport of German supplies.

 Despite a French counter-attack that saw the deaths of many Frenchmen on the battlefields at Ardennes, the Germans continued to march into France. They were eventually halted by the allies at the river Marne.?

 British troops had advanced from the northern coast of France to the Belgian town of Mons. Although they initially held off the Germans, they were soon forced to retreat.

 The British lost a huge number of men at the first battle of Ypres.

 By Christmas, all hopes that the war would be over had gone and the holiday saw men of both sides digging themselves into the trenches of the Western Front.

Dec 1914 Zeppelins The first Zeppelins appeared over the English coast.

April 1916 Romania enter the war Romania joined the war on the side of the Allies. But within a few months was occupied by Germans and Austrians.
31 May 1916 Battle of Jutland This was the only truly large-scale naval battle of the war. German forces, confined to port by a British naval blockade, came out in the hope of splitting the British fleet and destroying it ship by ship. However, the British admiral, Beatty, aware that the German tactics were the same as those used by Nelson at Trafalgar, sent a smaller force to lure the German's into the range of Admiral Jellicoe's main fleet. Although Beatty's idea worked, the exchange of fire was brief and the German's withdrew.
1 June 1916 Battle of Jutland The British and German naval forces met again but the battle was inconclusive. The German ships did a great deal of damage to British ships before once again withdrawing and the British Admiral Jellicoe decided not to give chase.?

Although British losses were heavier than the German, the battle had alarmed both the Kaiser and the German Admiral Scheer and they decided to keep their fleet consigned to harbour for the remainder of the war.

28 Nov 1916 First Aeroplane raid The first German air raid on London took place. The Germans hoped that by making raids on London and the South East, the British Air Force would be forced into protecting the home front rather than attacking the German air force.
Dec 1916 Lloyd George Prime Minister Lloyd George became Prime Minister of the war time coalition. His war cabinet, unlike that of his predecessor, met every day. However, there was considerable disagreement among the members of the Cabinet, especially between Lloyd George and his war secretary, Sir Douglas Haig. Lloyd George suspected Haig of squandering life needlessly and was suspicious of his demands for more men and freedom of action in the field.
21 Feb - Nov 1916 Battle of Verdun The Germans mounted an attack on the French at Verdun designed to 'bleed the French dry'. Although the fighting continued for nine months, the battle was inconclusive. Casualties were enormous on both sides with the Germans losing 430,000 men and the French 540,000.
1 July - Nov 1916 Battle of the Somme The battle was preceded by a week long artillery bombardment of the German line which was supposed to destroy the barbed wire defences placed along the German line but only actually succeeded in making no mans land a mess of mud and craters. The five month long battle saw the deaths of 420,000 British soldiers (60,000 on the first day), 200,000 French soldiers and 500,000 German soldiers all for a total land gain of just 25 miles.
1917 New war commander Lloyd George, who had never trusted his war minister's ability to direct the war, persuaded the Cabinet to appoint the French General Nivelle as supreme war commander over Haig's head. Haig was assured that the appointment was for one operation only and that if he felt the British army was being misused by the Frenchman he could appeal to the British government.
July - Nov 1917 W.front Passchendale The operation commanded by the French General, Nivelle, went wrong and caused the loss of many French soldiers. Haig protested to the British government and advocated trying his own scheme for a breakthrough. At the resulting battle of Passchendale, Haig broke his promise to call off the battle if the first stage failed because he did not want to lose face with the government.
1917 Churchill Minister of Munitions Following the heavy defeat at Passchendale, Lloyd George decided that he wanted Churchill in the Cabinet. Churchill was duly appointed Minister of Munitions.
1917 Reinforcements sent to Italy The Italians had lost many men trying to hold the line between Italy and the Central Powers. British and French reinforcements were sent to hold the line.
early 1917 German U-boat campaign In Germany, orders were given to step up the U-boat campaign. All allied or neutral ships were to be sunk on sight and in one month almost a million tons of shipping was sunk. Neutral countries became reluctant to ship goods to Britain and Lloyd George ordered all ships carrying provisions to Britain to be given a convoy.
