Word War I Trench Warfare

World War I, also knowns as The First World War was fought mainly in Europe during the years 1914-1918. Until finally in 1919 a peace treaty was signed between Allied and Central Powers.
This war was fought between Allied powers (Russian Empire, France, British Empire, Italy, Japanese Empire and the United States) and Central Powers (Germany, Hungary, Turkey and the Bulgarian Empire) in locations such as Europe, Africa and the Middle East. Although it was a massive war which involved over 9 million death soldiers, the type of combat was a trench warfare.
This meant that the soldiers would arrive at the front line, dig a big hole to cover from enemy fire and build a kind of shelter and they would spend weeks firing with rifles and machine guns against the enemies.
Soldiers had static positions in combat and took turns to operate the fire arms and the artillery. This was the type of combat which took place during most of the war but at the end the development of tanks allowed both sides to move comfortably around the field. The weapons used during World War I were mainly Infantry weapons, machine guns and artillery. Other types of weapons which were less common were Mortars, Toxic Gas, Mining, Flamethrowers and Combat Planes. At the end of the war anti-tank guns were developed to fight the armored vehicles. The soldiers communicated with theirs superiors and with other trenches using instruments such as the telegraph, the telephone and homing pigeons. More elementary communications like signal lamps were also involved.
