Why were trenches used?

Along with the rifle, another major gun was used at the trenches. This was the machine gun. This machine gun could fire rounds a lot faster than rifles could. A soldier would sit in the trench behind the gun and a lot of sandbags and shoot at the soldiers that were in the "no man's land" in between the two trenches.
World War 1 consisted of the first poisonous gas attacks in history. Gasses such as chlorine, mustard gas, and tear gas were all used to help defeat the enemy. These gases could give the body blisters and spasms, and could also lead to suffocation. Tear gas would even contribute to blindness if it got into the eyes. Around 1,230,853 people were wounded or killed by gas in World War 1.
Grenades started up in 1915, just a year after the war started. They were needed because it would be easier to damage the other trenches if they could throw something down into them. The Germans produced a stick grenade that they could throw into trenches while the British made the Mills bomb that was shaped like a pineapple. To activate the Mills bomb, you had to pull its pin and then throw it before it exploded in your hands. Eventually, fire and poisonous gas was coming out of grenades as the technology quickly advanced. Bombing parties were then created where soldiers would get together with grenades and run to throw them into the opposing sides trenches.
