Due to the fierce resistance of French, British and Belgian troops in the Battle of the Marne River and the Russian attack on the Eastern Front, the German quick war plan went bankrupt. The two sides in the western front fought in trenches, confronted each other for a long time and turned to positional warfare. [5]

As both sides regarded 19 16 as a decisive year, three large-scale land wars took place this year, namely the Battle of Verdun on the western front, the Battle of the Somme on the eastern front and the Russian summer offensive. At sea, after the Jutland naval battle, Britain still firmly controlled the sea power. At this stage, the strategic initiative of the war was transferred to the side of the allies. [6]
