Technology during World War I
From Free net encyclopedia
Technology during World War I reflected a trend to industrialism and the application of mass production to the production of weapons and of technology, in general, to warfare. This trend began fifty years earlier during the U.S. Civil War, and continued through many smaller conflicts in which new weapons were tested.
August 1914 marked the end of a relatively peaceful century in Europe with unprecedented invention and new science. The 19th century vision of a peaceful future fed by ever-increasing prosperity through technology was largely shattered by the war and, after the technological escalation during World War II, it was apparent that whatever the gains in prosperity and comfort due to technology applied to civilian uses, these benefits would always be under the shadow of the horrors of technology applied to warfare.

Trench warfare
The new metallurgical and chemical industries, and many innovative mechanical inventions, had created new firepower that made defense almost invincible and attack almost impossible. These innovations included bolt-action infantry rifles, rifled artillery, zigzag trenches and machine guns, and their application had the effect of making it difficult or nearly impossible to cross defended ground. The hand grenade, already in existence —though crude—developed rapidly as an aid to attacking trenches.
Attacking the entrenched enemy was so difficult that tunneling underneath enemy lines became one of the major efforts during the war. Once enemy positions were undermined, huge amounts of explosives would be planted and detonated as part of the preparation for an overland charge. Sensitive listening devices that could detect the sounds of digging were a crucial method of defense against these underground incursions. The British proved especially adept at these tactics, thanks to the skill of their tunnel-digging "sappers" and the sophistication of their listening devices.
Poison gas

At the beginning of the war, Germany had the most advanced chemical industry in the world, accounting for more than 80% of the world's dye and chemical production. Although the use of poison gas had been banned in the Hague Conventions of 1899 and 1907, Germany turned to this industry for what it hoped would be a decisive weapon to break the deadlock of trench warfare. Chlorine gas was first used on the battlefield in April 1915 at the Second Battle of Ypres in Belgium. Later, mustard gas, phosgene and other gasses were used. England and France soon followed suit with their own gas weapons. The first defenses against gas were makeshift, mainly rags soaked in water or urine. Later, relatively effective gas masks were developed, and these greatly reduced the effectiveness of gas as a weapon. Although it sometimes resulted in brief tactical advantages and probably caused over 1,000,000 casualties, gas seems to have had no significant effect on the course of the war. It only added immeasurable suffering to an already horrific conflict.
Command and control
In the early days of the war, generals tried to direct tactics from headquarters many miles from the front, with messages being carried back and forth by couriers on motorcycles. It was soon realized that more immediate methods of communication were needed.
Radio sets of the period were too heavy to carry into battle, and phone lines laid were quickly broken. Runners, flashing lights, and mirrors were used, but dogs were used only rarely, as troops tended to adopt them as pets and men would volunteer to go as runners in the dog's place. There were also aircraft (called "contact patrols") that could carry messages between headquarters and forward positions, sometimes dropping their messages without landing.
The new long-range artillery developed just before the war now had to fire at positions it could not see. Typical tactics were to pound the enemy front lines and then stop to let infantry move forward, hoping that the enemy line was broken, though it rarely was. The "liftoff" and then the creeping barrage were developed to keep artillery fire landing directly in front of the infantry "as it advanced". Communications being impossible, the danger was that the barrage would move too fast--losing the protection--or too slow--killing your own troops with friendly fire.
There were also countermeasures to these artillery tactics: by aiming a counter barrage directly behind an enemy's creeping barrage, one could target the infantry that was following the creeping barrage. Microphones were used to triangulate on the position of enemy guns and engage in counter-battery fire. Muzzle flashes of guns could also be spotted and used to target enemy artillery. Eventually 85-90% of guns were being wiped out in the first few minutes of any given battle.
War of attrition
All 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 this hope proved futile.
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 village.
In the end, the war ended through a combination of attrition (of men and materiel), advances on the battlefield, and a breakdown of morale and productivity on the German home--front due to an effective naval blockade of her seaports.
Air warfare
As with most other technologies, the aircraft underwent many improvements during World War I. Early war aircraft were not much different in design from the original Wright Flyer, which made its first flight over a decade earlier.
While early air spotters were unarmed, they soon began firing at each other with handheld weapons and even throwing spears. An arms race commenced, quickly leading to increasingly agile planes equipped with machine guns. A key innovation was the interrupter gear, a German invention that allowed a machine gun to be mounted behind the propeller so the pilot could fire directly ahead, along the plane's flight path.
Germany led the world in the design of Zeppelins, and they used these airships to make occasional bombing raids on military targets, London and other British cities, but without any great effect.
Tanks
Template:Main Image:GermanphotowithEnglishTank.jpg Although the concept of the tank had been suggested as early as the 1890s, few authorities showed interest in them until the trench stalemate of World War I caused serious contemplation of unending war and ever escalating casualties. In Britain, a Landships Committee was formed, and teamed with the Inventions Committee, set out to develop a practicable weapon.
Based on the caterpillar track (first invented in 1770 and perfected in the early 1900s) and the four-stroke gasoline powered Internal combustion engine (perfected in the 1870s), early tanks were fitted with Maxim type guns or Lewis guns, armour plating, and their caterpillar tracks were configured to allow crossing of an eight-foot wide trench.
Early tanks were unreliable, breaking down often. Though they first terrified the Germans, their use in 1917 engangements provided more opportunities for development than actual battle successes. It was also realized that new tactics had to be developed to make best use of this weapon. In particular, planners learned that tanks needed infantry support and massed formations to be effective. Once tanks could be fielded in the hundreds, such as they were at the Battle of Cambrai in November 1917, they began to show their potential. Still, reliability was the achilles heel of tanks throughout the remainder of the war. In the Battle of Amiens, a major Entente counter offensive near the end of the war, British forces went to field with 534 tanks. After several days only a few were still in commission, those that suffered mechanical difficulties outnumbering those disabled by enemy fire.
Regardless of their effects on WWI, tank technology and mechanized warfare had been launched and grew increasingly sophisticated in the years following the war. By World War II, the tank had evolved to a fearsome weapon which made the trench obsolete, just as the trench and the machine gun had made horse-mounted cavalry obsolete.
Submarines
World War I was the first conflict in which submarines were a serious weapon of war. In the years shortly before the war, the relatively sophisticated propulsion system of diesel power while surfaced and battery power while submerged was introduced.
The United Kingdom relied heavily on imports to feed its population and supply its war industry, and the German navy hoped to blockade and starve Britain using U-boats to attack merchant ships in unrestricted submarine warfare. This struggle between German submarines and British counter measures became known as the First Battle of the Atlantic. As German submarines became more numerous and effective, the British sought ways to protect their merchant ships. "Q-ships," attack vessels disguised as a civilian ships, was one early strategy.
Consolidating merchant ships into convoys protected by one or more armed navy vessels was adopted later in the war. There was initially a great deal of debate about this approach, out of fear that it would just provide German U-boats with a wealth of convenient targets. Thanks to the development of active and passive sonar devices, coupled with increasingly deadly anti-submarine weapons, the convoy system reduced British losses to U-boats to a small fraction of their former level.
Mobility
Between late 1914 and early 1918, the Western Front hardly moved. Ironically, the beginning of the end for Germany started with a huge German advance. In 1917, when Russia surrendered after the October Revolution, Germany was able to move many troops to the Western Front. Using new stormtrooper tactics developed by Oskar von Hutier, the Germans pushed forward some tens of kilometers and, by March 1918, the German advance came to the outskirts of Paris.
In the Battle of Amiens of August 1918, the Entente forces began a counter attack what would be called the Hundred Days Offensive. The Australian and Canadian divisions that spearheaded the attack managed to advance 13 kilometers on the first day alone. These battles marked the end of trench warfare on the Western Front and a return to mobile warfare.
The Hindenburg Line fell to the Allies and the Canal du Nord was crossed. In Berlin, Kaiser Wilhelm was told Germany had lost, and must now surrender. There were no advances in the Fall as details of the surrender were negotiated, leading to the Armistice on November 11, 1918.
The war was over. But a new mobility-driven form of warfare had emerged, that would be mastered by the defeated Germans and deployed as their 1939 blitzkrieg, or lightning warfare, embodying all they had learned in 1918.
