Technology during World War I
Technology during World War I (1914–1918) reflected a trend toward industrialism and the application of mass-production methods to weapons and to the technology of warfare in general. This trend began at least fifty years prior to World War I during the American Civil War of 1861–1865,[1] and continued through many smaller conflicts in which soldiers and strategists tested new weapons.
World War I weapons included types standardised and improved over the preceding period, together with some newly developed types using innovative technology and a number of improvised weapons used in trench warfare. Military technology of the time included important innovations in machine guns, grenades, and artillery, along with essentially new weapons such as submarines, poison gas, warplanes and tanks.[2]
The earlier years of the First World War could be characterized as a clash of 20th-century technology with 19th-century military science creating ineffective battles with huge numbers of casualties on both sides. On land, the quick descent into trench warfare came as a surprise, and only in the final year of the war did the major armies make effective steps in revolutionizing matters of command and control and tactics to adapt to the modern battlefield and start to harness the myriad new technologies to effective military purposes. Tactical reorganizations (such as shifting the focus of command from the 100+ man company to the 10+ man squad) went hand-in-hand with armoured cars, the first submachine guns, and automatic rifles that a single individual soldier could carry and use.
Artillery also underwent a revolution. In 1914, cannons were positioned in the front line and fired directly at their targets. By 1917, indirect fire with guns (as well as mortars and even machine guns) was commonplace, using new techniques for spotting and ranging, notably, aircraft and the often overlooked field telephone.[8]
At the beginning of the war, artillery was often sited in the front line to fire over open sights at enemy infantry. During the war, the following improvements were made:
Germany was far ahead of the Allies in using heavy indirect fire. The German Army employed 150 mm (6 in) and 210 mm (8 in) howitzers in 1914, when typical French and British guns were only 75 mm (3 in) and 105 mm (4 in). The British had a 6-inch (152 mm) howitzer, but it was so heavy it had to be hauled to the field in pieces and assembled. The Germans also fielded Austrian 305 mm (12 in) and 420 mm (17 in) guns and, even at the beginning of the war, had inventories of various calibres of Minenwerfer, which were ideally suited for trench warfare.[9][10]
Field artillery entered the war with the idea that each gun should be accompanied by hundreds of shells, and armouries ought to have about a thousand on hand for resupply. This proved utterly inadequate when it became commonplace for a gun to sit in one place and fire a hundred shells or more per day for weeks or months on end. To meet the resulting Shell Crisis of 1915, factories were hastily converted from other purposes to make more ammunition. Railways to the front were expanded or built, leaving the question of the last mile. Horses in World War I were the main answer, and their high death rate seriously weakened the Central Powers late in the war. In many places the newly invented trench railways helped. The new motor trucks as yet lacked pneumatic tires, versatile suspension, and other improvements that in later decades would allow them to perform well.
War of attrition[edit]
The countries involved in the war applied the full force of industrial mass-production to the manufacture of weapons and ammunition, especially artillery shells. Women on the home-front played a crucial role in this by working in munitions factories. This complete mobilization of a nation's resources, or "total war" meant that not only the armies, but also the economies of the warring nations were in competition.
For a time, in 1914–1915, some hoped that the war could be won through an attrition of materiel—that the enemy's supply of artillery shells could be exhausted in futile exchanges. But production was ramped up on both sides and hopes proved futile. In Britain the Shell Crisis of 1915 brought down the British government, and led to the building of HM Factory, Gretna, a huge munitions factory on the English-Scottish border.
The war of attrition then focused on another resource: human lives. In the Battle of Verdun in particular, German Chief of Staff Erich Von Falkenhayn hoped to "bleed France white" through repeated attacks on this French city.
In the end, the war ended through a combination of attrition (of men and material), advances on the battlefield, arrival of American troops in large numbers, and a breakdown of morale and production on the German home-front due to an effective naval blockade of her seaports.
