			This was the land-based element of a strategy intended to allow 
			Allied ships to pass through the Dardanelles, capture Constantinople

			The 1915 loan, due for payment between 1925 and 1945, paid 4.5% but 
			was issued at par (investors received no discount at the time of 
			buying their stock). When the applications were added up, it was 
			found that the loan had nominally raised £900m, but more than a 
			third of that total was actually conversion of existing debt. Of the 
			new money, one third was contributed by the banks.

			in the United Kingdom by the Military Service Act, 1916. | 
		
			| 1916 | 
			February | 21st | The Battle of Verdun 
			begins with a German attack on the fortified French town of Verdun.  
			Verdun was to be 
			the largest and longest (303 days) battle of the First World War on 
			the Western Front, and one of the most costly in history. The French 
			eventually secured a defensive victory, but in so doing sustained 
			casualties (killed and wounded) of some 550,000 men - German 
			casualties were over 430,000. | 
		
			| 1916 | April | 
			24th-29th | Easter Rising by Irish 
			rebels for independence from the United Kingdom. The Rising was 
			launched by Irish republicans to end British rule in Ireland and 
			establish an independent Irish Republic. 485 people were killed: 
			about 54% were civilians, 30% were British military and police, and 
			16% were Irish rebels. More than 2,600 were wounded. | 
		
			| 1916 | May | 10th | Germany suspends 
			unrestricted submarine warfare. | 
		
			|   |   | 
			31st-1st June | The Battle of Jutland 
			fought between Britain’s 
			Grand Fleet and Germany’s 
			High Seas Fleet. It was the largest naval battle and the only 
			full-scale clash of battleships in that war. It was also the last 
			major battle in history fought primarily by battleships. Both sides 
			claimed victory. The British lost more ships than the Germans and twice as many 
			men, but succeeded in containing the German fleet which never again 
			seriously challenged British control of the North Sea. | 
		
			| 1916 | June | 4th-20th 
			Sept. | The Eastern Front 
			(present-day western Ukraine): the Brusilov Offensive was to be the 
			most successful Russian offensive of the First World War in which 
			tactics that were later to prove successful on the Western Front (a 
			short, sharp artillery bombardment and shock troops to exploit weak 
			points) were employed. Overall, the attack drew Austro-Hungarian 
			forces away from the Italian Front putting increased pressure on the 
			already strained and increasingly demoralised Austro-Hungarian Army. 
			Germany was forced to redirect troops to the Eastern Front to 
			support its ally. However, the Russians were never able to duplicate 
			General Brusilov’s 
			success and this was to be their last major offensive of the war. | 
		
			|   |   | 5th | The HMS Hampshire is 
			mined and sunk off the Orkney Islands resulting in the death of Lord 
			Kitchener, British Secretary of State for War, who was on a mission 
			to Russia to discuss munitions shortages, military strategy and 
			financial difficulties with the Imperial Russian Government. | 
		
			| 1916 | July | 1st | Opening phase of the 
			Battle of the Somme. This battle, a joint operation between British 
			and French forces, was intended to achieve a decisive victory over 
			the Germans on the Western Front. Like Verdun for the French, for 
			the British the Somme has come to represent the loss and apparent 
			futility of the War. Over 1 million men from all sides were killed, 
			wounded or captured. British casualties on the first day – numbering 
			over 57,000, of which 19,240 were killed – make it the bloodiest day 
			in British military history. |

			Joseph Joffre as Commander-in-Chief of the French Army. | 
		
			|   |   | 18th | Battle of Verdun ends 
			with enormous casualties on both sides.  It is estimated that 
			143,000 French and 163,000 German troops lost their lives. | 
		
			| 1917 | 
			January | 13th | 1917 War Loan: the Government 
			borrowing more money to pay for the War.  The 1917 loan paid 
			interest at 5%, or 4% tax free for 25 years, and was offered at a 5% 
			discount (it cost £95 to buy £100 of stock). The loan raised 
			£2,127M, but only £867M of that total, or 41%, was new money. The 
			rest came from treasury bills, exchequer bonds and previous war loan 
			stock being converted to the more favourable terms. As before the 
			banks were required to market the loan to their customers. | 
		
			|   | 
			  | 17th | The German Foreign Secretary Arthur 
			Zimmermann sends a telegram to his ambassador in Mexico, instructing 
			him to propose to the Mexican government an alliance against the 
			United States. The telegram was intercepted and decoded by British 
			intelligence who disclosed its contents to the Americans helping to 
			generate support for the United States declaration of war on Germany 
			in April. | 
		
			| 1917 | 
			February | 1st | Germany resumes 
			unrestricted submarine warfare. |

			Lawrence of Arabia seize the Jordanian port of Aqaba. | 
		
			|   |   | 21st | Alexander Kerensky 
			replaces Georgy Lvov as Minister-President of the Russian 
			Provisional Government. | 
		
			|   |   | 31st | The Third Battle of 
			Ypres (also known as Battle of Passchendaele) in Belgium begins. The 
			area surrounding Ypres was a key battleground throughout the war. By 
			1917 British forces were suffering steady casualties while holding a 
			salient surrounded by higher ground. The offensive aimed to break 
			out of this poor position and, by capturing an important rail 
			junction a few miles to the east, undermine the German position in 
			Flanders and threaten the German submarine base at Bruges, for the 
			German U-boat campaign was by then threatening Britain with defeat. 
			For most of the attack persistently heavy rain created extremely 
			muddy conditions, making movement difficult, and although the 
			Canadians eventually captured the Passchendaele ridge (10th 
			November), the vital railway junction was not taken. Both sides 
			suffered heavy casualties while the British made no strategic gain. | 
		
			| 1917 |

			Trotsky signs the peace treaty with Germany. | 
		
			|   |   | 4th | First known case of what 
			will later be called
			“Spanish 
			Flu”: 
			Private Albert Gitchell at Camp Funston, Fort Riley, Kansas. This 
			unusually deadly influenza pandemic infected 500 million people 
			around the world, and resulted in the deaths of 50 to 100 million 
			(three to five percent of the world’s 
			population), making it one of the deadliest natural disasters in 
			human history. | 
		
			|   |   | 7th | First German air raid on 
			London is undertaken on a moonless night by a German Zeppelin-Staaken 
			R.VI heavy bomber. At least 12 civilians were killed and over 23 
			others seriously injured. Four houses were destroyed and many 
			damaged. | 
		
			|   |   | 
			21st-5th April | First phase of the 
			German Spring Offensive, Operation Michael (also known as Second Battle of 
			the Somme). Following their defeat of Russia, Germany concentrated 
			its resources on the Western Front where it used them to mount a 
			massive attack. On the 21st March 1918, the Germans attacked with a 
			huge concentration of artillery, gas, smoke and infantry allowing 
			them to achieve unprecedented gains. Although their offensives were 
			tactically successful they were strategic failures. Their advances 
			had no decisive goal other than to break through the Allied line, 
			which bent but did not give. German casualties were high. To better 
			co-ordinate a united defence the Allies appointed the French Marshal 
			Foch as overall Commander. The tide began to turn and by early 
			summer the German offensives ground to a halt. | 
		
			|   |   | 26th | French Marshal Ferdinand 
			Foch is appointed Supreme Commander of all Allied forces. | 
		
			| 1918 | April | 1st | Royal Air Force founded 
			by combining the Royal Flying Corps and the Royal Naval Air Service. |

 | The Hundred Days 
			Offensive commences leading to Germany’s 
			defeat in the War. After surviving the German Spring Offensives on 
			the Western Front, Allied forces launched a counter-attack and from 
			the summer of 1918 onwards they were constantly on the advance until 
			the Armistice in November. The Offensive opened with the Battle of Amiens. Secret preparations 
			ensured surprise and the BEF made gains of seven miles on that one 
			day – German General Erich Ludendorff described it as the
			“black 
			day” 
			of the German Army.
 | 
		
			| 1918 | 
			September | 
			19th-25th | The Battle of Megiddo 
			(19-25 September 1918) arked the beginning of the final British-led 
			offensive in the Sinai and Palestine Campaign. It successfully 
			combined cavalry, infantry, artillery, armoured vehicles and 
			aircraft to achieve decisive victory over the Ottoman Turks and 
			their German allies. It was the start of a series of important 
			Allied victories that ultimately led to the collapse of Ottoman 
			Turkish forces and their eventual withdrawal from the War. |
