How the development of trench warfare at the beginning of World War I affected the progress of the war?

World War I was less than one year old when British writer H. G. Wells lamented the fate of humanity at the hands of "man's increasing power of destruction" (H. G. Wells, "Civilization at the Breaking Point," New York Times, May 27, 1915, 2). Although considered a father of science fiction, Wells was observing something all too real—technology had changed the face of combat in World War I and ultimately accounted for an unprecedented loss of human life.

Infantry warfare had depended upon hand-to-hand combat. World War I popularized the use of the machine gun—capable of bringing down row after row of soldiers from a distance on the battlefield. This weapon, along with barbed wire and mines, made movement across open land both difficult and dangerous. Thus trench warfare was born. The British introduced tanks in 1916; they were used with airplanes and artillery to advance the front. The advent of chemical warfare added to the soldier's perils.

Sea and airborne weapons made killing from a distance more effective as well. Guns mounted on ships were able to strike targets up to twenty miles inland. The stealth and speed of German submarines gave Germany a considerable advantage in its dominance of the North Sea. Although airplanes were technologically crude, they offered a psychological advantage. Fighter pilot aces such as Manfred von Richthofen, Germany's "Red Baron," became celebrities and heroes, capturing the world's imagination with their daring and thrilling mid-air maneuvers.

Newspapers charted the public's reaction—horror and vengeance—to these technological advancements. A few weeks after the Germans first used poison gas in Ypres, Belgium, on April 22, 1915, a London newswire to the New York Times described the brutal details of the attack and the immediate effects on the soldiers, concluding: "It is without doubt the most awful form of scientific torture." Yet a Daily Chronicle [London] editorial urged Britain to retaliate with poison gas use of its own (quoted in New York Times, May 7, 1915, 2). In fact, Germany claimed that the Allies were already using mines charged with poison gas. So horrified were people by chemical warfare that the use of poison gases was banned for future wars, although not until 1925.

When Germany's plan for a swift military victory went unrealized, the pace of war bogged down. Both sides tried to break this stalemate through the use of force. In previous wars, victory was achieved through territorial supremacy; in World War I it was accomplished by simply outlasting the opponent—a "war of attrition." When fighting first broke out in August 1914, many hoped the war would be short-lived; few predicted a conflict that would last for more than four years and scar an entire generation with its unprecedented brutality.

World War I Begins

At the dawn of the 20th century, few anticipated a global war, but what came to be known as the Great War began on June 28, 1914, with the assassinations of Austrian Archduke Franz Ferdinand and his wife, Sophie, while they were visiting Sarajevo, Bosnia, a country recently annexed into the Austrian Empire. Many Bosnians and their Serbian neighbors resented this foreign rule and the Archduke’s visit to Sarajevo provided the opportunity for a small band of Serbian dissidents to strike back. Austria responded to the assassinations by teaming up with its ally, Germany, and declaring war on Serbia. The conflict soon involved Russia, France and Belgium. Fearful of a full-scale world war that would threaten its sea routes to other countries, Great Britain joined the fight against Germany and Austria.

Each country believed the fighting would last only a few months. Nations were categorized either as Central Powers or Allies. Countries that joined the Central Powers, such as Bulgaria and the Ottoman Empire, supported Austria-Hungary and Germany. The Allies were Russia, France, Belgium and Great Britain, but they were later joined by Japan, Romania, China and the United States.

No Man’s Land: Trench Warfare

How the development of trench warfare at the beginning of World War I affected the progress of the war?

During World War I, trench warfare was a defensive military tactic used extensively by both sides, allowing soldiers some protection from enemy fire but also hindering troops from readily advancing and thus prolonging the war. Trench warfare was the major combat tactic in France and Belgium. Trenches were often dug up to 12 feet deep and stretched for miles. For stability, some trenches included wooden beams and/or sandbags. Even during lulls in the fighting, death occurred almost daily in the trenches due to a sniper’s bullet or the unsanitary living conditions which resulted in many diseases such as dysentery, typhus and cholera. Other diseases caused by the poor conditions were trench mouth and trench foot*.

*Trench mouth was an infection of the mouth due to overgrowth of certain oral bacteria. The condition was made worse by poor oral hygiene, smoking, malnutrition and psychological stress. To prevent trench foot, a fungal disease caused by exposure to wet and cold, soldiers frequently added wooden planks in the trenches to keep from having to stand in water.

Barbed wire and explosive mines—as well as bullets and grenades—were essential weapons used to hinder infantry advances across “No Man’s Land,” the bleak landscape between the trenches of the opposing sides.

New offensive weapons were implemented during the war including tanks and poison gases*. 

*Tanks, armored against artillery fire, were capable of rolling over barbed wire as well as crossing treacherous terrain.

Chlorine was one of the poisonous gases used in World War I. It was damaging to the eyes, nose, throat and lungs, and produced symptoms ranging from irritation to blindness and death.)

In 1915, the Germans used poison gases against the Allies fighting in the trenches on the Western Front. To protect soldiers from chemical warfare, gas masks were developed. Great Britain made one of the first types of masks capable of minimizing the deadly impact of these gases on their troops.

Though considered a novelty when the war began, aircraft were used by both sides for reconnaissance, allowing personnel to observe enemy troop positions, to direct artillery fire and to photograph enemy lines. By the end of the war, the concepts of aerial combat and aerial bombing had come into being.

How did trench warfare affect the progress of the war?

During World War I, trench warfare was a defensive military tactic used extensively by both sides, allowing soldiers some protection from enemy fire but also hindering troops from readily advancing and thus prolonging the war.

What was the effect of trench warfare in the first two years of World War I?

Disease and 'shell shock' were rampant in the trenches. As they were often effectively trapped in the trenches for long periods of time, under nearly constant bombardment, many soldiers suffered from “shell shock,” the debilitating mental illness known today as post-traumatic stress disorder (PTSD).

How did the implementation of trench warfare affect the course of World War I?

Trench warfare shielded the troops from massive attacks and provided cover while they fired weapons at the opposing side. Northern France and Belgium saw most of the trench warfare combat. In September 1914, in an effort to bypass the trench lines and capture ports, the Germans began their Race to the Sea.
