Poison Gas

Through out the war, nations developed various weapons to increase their chances at winning the war. Some of these advancements failed and turned out not to be useful on the battlefield, but one of the most successful weapons that was developed during World War 1 was poison gas. Although they had produced poison gas before WWI nations soon began to see how it could be extremely beneficial in the War. The Germans were the first to use poison gas and they used to both kill the enemies and also to try and get the enemies to flee out of the trenches and run right into the their machine guns that were waiting as they jumped out of the trenches. The British and French soon began to use poison gas and by the end of the war, it became one of the most feared weapons in history. Armies would drop multiple gas bombs right on their enemies and hundreds of victims would be infected. Although the death to poison gas number is not very high, there were still a vast number of victims to poison gas. Eventually, they developed a gas mask but even then they were not 100% functional and if there was any sort of crack in these flawed masks, the soldier would be exposed.
