With the assassination of the Archduke Franz Ferdinand of Austria by a Serbian nationalist in Sarajevo, a fuse is lit and the armies of Europe, and soon the entire world, will be on the march. This war will be like no other ever fought in human history. With the introduction of machine guns, flying machines, tanks and chemical weapons, casualties will be measured in the millions, and advances against the enemy measured in yards. Eight major powers struggle for supremacy. The Central Powers of Germany, the Austro-Hungarian Empire, and the Ottoman Empire are aligned against the great alliance of France, the British Empire, the Russian Empire, Italy, and eventually the United States.
