"What ideas, facts, concepts, or information did you learn from the video that you didn't know before viewing it?"

Some major things I did not know about the war was the usage of chemical weapons, I had thought they didn't come in until WWII, but I was wrong. I also hadn't realized the technology and weapons had advanced that greatly already. Even though this was the era of getting into those new weapons, I thought it all started later in years to come. I also hadn't realized how dangerous the barbed wire mess was out in "No Mans Land", it's sort of scary having to be the one who had to go out and cut that up, and having the fear of being blown to pieces by bombing and grenades. I knew there were sorts of guns used, I just didn't know what type of guns. Something else I didn't know was that horses were used more in the Eastern front instead of the Western front. Another I learned was how advanced the trenches were. I was amazed at how well laid out they were, and how much thought was put into them just for protection and easy access to go and attack. The last thing I learned was that Sliefen died before his plan was even put into action, and his plan failed.
