World War 1, better known as "The Great War" started because of the assassination of the Austrian Archduke Francis Ferdinand. On July 28, 1914 Gavrilo Princip, a Serbian nationalist, murdered the one appointed to the throne of Austria-Hungary to protest Habsburg rule of Bosnia.

Mutual defense pacts drew in the allies of the warring nations including France, Belgium, Great Britain, Austria-Hungary and the Ottoman Empire among others.

Germany temporarily halted submarine warfare to avoid bringing the United States into World War I.

He employed the use of 1,500 British guns backed by almost the same amount of French artillery. As the barrage commenced, British infantry would flood into the front line trenches in preparation to advance on the broken German front. The barrage was set to begin
