The Flamethrower<br />The idea of being able to burn one’s enemies to death has consistently been on the minds of combatants throughout history; however, it was not until 1915 Germany was able to deploy a successful man-portable flamethrower.<br />The flamethrower was especially useful because even just the idea of being burned alive drove men from the trenches into the open where they could be cut down by rifle and machine gun fire.<br />The terrible nature of the flamethrower, Flammenwerfer in German, meant that the troops carrying them were marked men. As soon as they were spotted, they became the targets of gunfire. Should one happen to be taken prisoner, they were often subjected to summary execution.<br /><br />The British went a different way with their flamethrowers and developed the Livens Large Gallery Flame Projector. These were stationary weapons deployed in long trenches forward of the lines preceding an attack. The nozzle would spring out of the ground and send a wall of flame 300 feet in the enemy’s direction.<br />These were used with great effectiveness at the Somme on July 1, 1916 when they burned out a section of the German line before British infantry was able to rush in and capture the burning remnants.<br />2. Trench Knife<br />Even with the advent of the firearm, hand-to-hand combat was still a given on the battlefield. However, with the introduction of trench warfare, a new weapon was needed in order to fight effectively in such close quarters. Enter the trench knife.<br />The most terrifying trench knives were developed by the United States. The M1917, America’s first trench knife, combined three killing tools in one. The blade of the weapon was triangular which meant it could only be used for stabbing, but it inflicted terrible wounds.<br />Triangular stab wounds were so gruesome that they were eventually banned by the Geneva Conventions in 1949 because they cause undue suffering. The knife also had a “knuckle duster” hand guard mounted with spikes in order to deliver maximum damage with a punching attack. Finally, the knife had a “skull crusher” pommel on the bottom in order to smash the enemy’s head with a downward attack.<br />An improved design, the Mark I Trench Knife, was developed in 1918 but didn’t see use until WWII.<br />3. Poison Gas<br />Of course any list of terrifying weapons of war has to include poison gas; it is the epitome of horrible weapons. Poisonous gas came in three main forms: Chlorine, Phosgene, and Mustard Gas.<br />The first poison gas attack was launched by the Germans against French forces at Ypres in 1915. After that, both sides began to develop their chemical weapon arsenals as well as countermeasures.<br />The true purpose of the gas was generally not to kill — though it certainly could — but to produce large numbers of casualties or to pollute the battlefield and force the enemy from their positions.<br />Gas also caused mass panic amongst the troops because of the choking and blindness brought on by exposure causing them to flee their positions. Mustard gas was particularly terrible because in addition to severely irritating the throat, lungs, and eyes, it also burned exposed skin, creating large painful blisters.<br />4. Artillery<br />Though artillery had been around for centuries leading up to WWI, its use on the battlefields of Europe was unprecedented. This was because of two reasons.<br />First, some of the largest guns ever used in combat were employed during the war.<br />Second, because the world had never seen such concentrations of artillery before.<br />Artillery shells were fired in mass concentrations that turned the earth into such a quagmire that later shells would fail to detonate and instead they would simply bury themselves into the ground. Massive bombardments destroyed trenches and buried men alive.<br />Artillery bombardments were so prolific that a new term, shell shock, was developed to describe the symptoms of survivors of horrendous bombardments.<br />@ SMSgt Minister Gerald A.

Gas for obvious reasons and the machine gun because no one had experienced them before and thus were using old tactics against new technology.

Nitrogen Mustard has saved countless lives in the form of the first chemotherapy and is still used today. While studying the effects of mustard gas on soldiers that had been exposed to it during WWI trying to find an antidote for it in case it was used again it was found that it was active at destroying rapidly reproducing cells. Cancers being rapid reproducers they tried it and found that they could actually treat cancer with it. This was one of the most fascinating things I learned when I went to school for my oncology nurse certification.

Artillery was used on all fronts and all terrain. The terrain around the French forts at Verdun still bares the scares and craters from German artillery used to reduce those forts. The top soil was burned, and could not support the growth of large trees or support agriculture. During battles the craters hampered the maneuver of infantry formations before they made it to the wire obstacles. So attacks on enemy trenches more often that not unsuccessful. Finally, the conditions caused by artillery affected the Germans and the allies equally.
