I'm doing an essay on the new weapons and technology in WW1 and i don't know where to find any information. We need at least 5 sheets and have to include information about The Machine Guns, Poison Gases, Tanks, Dreadnoughts, Submarines and Aircraft-Balloons and Aeroplanes(Fighters and Bombers). Please help me. Also i'm not sure how to structure this essay and what to write for the introduction and conclusion, in that we need to state wether we thought the technology did or did not help the fighting in the war. But we haven't even finished studying WW1 and we haven't got to the end. Please help though asap, thanks.
