The Battle of Verdun (21 February-15 December 1916) became the longest battle in modern history. It was originally planned by the German Chief of General Staff, Erich von Falkenhayn to secure victory for Germany on the Western Front.
The trench warfare of the Western Front encouraged the development of new weaponry to break the stalemate. Poison gas was one such development. The first significant gas attack occurred at Ypres in April 1915, when the Germans released clouds of poisonous chlorine.
