Impact
Brought an end to trench warfare Thousands of tanks made contribution
to British and French war effort Still used today
How Machine Guns Operate Two types of how machine guns received
energy Recoil system
Bolt locks to barrel Stays together moving forward and back
creating energy Gas System
Pressure of exploding gas drives piston Piston fires back a bolt to back of gun
which provides energy Both systems had cycles repeat over and
over again to fire bullets continuously
Before and During Before World War 1
Two armies charging at each other in an open field with mostly single fire muskets
Stabbed at each other with bayonets Lots of land gained at end of war
During World War 1 Machine guns kill thousands of men in an
open field Caused enemies to build trenches in
order to protect themselves from machine gun fire
Gained little land since both armies were stuck in trenches and became very hard to advance
How the Machine Gun Helped Led to invention of tanks and gas warfare
Made stalemates in trenches so people had to think of new ways of killing each other
Created an anti-aircraft weapon for ships and land bases
Created a weapon on airplanes instead of bombs
Were much more effective in killing masses of platoons or battalions than single firing guns

Types of Poisonous GasMustard Gas (C6H8CI2S):•Blistering agent•Caused skin to blister away, temporary blindness, uncontrollable watering of the eyes, and vomiting
Chlorine/Phosgene Gas:•Chocking agent•Burns or seriously damages respiratory system of whoever inhaled it
Blood Agents:•Interfered with the level of oxygen in the blood of the victim•Lessened oxygen levels killing victim of oxygen loss
VX (C11H26NO2PS):•Nerve Agent•Killed through loss of consciousness, impairment of normal breathing, and suffocating

Gas Attack on the Western Front
British Hypo Helmet Earliest protection used Had some protection with eye pieces Weak but broke easily
Small Box Respirator Invented after and worked better than the Hypo Helmet Protected whole face, eyes, and hands
Anti-Gas Chemicals All masked were dipped in these chemicals Consisted of sodium hyposulphite, washing soda, glycerin,
and water What to do without a mask?
All soldiers carried two masks (in case one was defective) If without a mask, soldiers were instructed to place a urine
filled cloth all over their face
Types of Protection Against Poisonous Gas
http://www.firstworldwar.com/photos/graphics/ww_man_horse_mask_01.jpg
Masks and Helmets were used by all even horses
Created By scientists in labs by combining different
chemicals with each other at different temperatures
Germans were the first to create poisonous gas
Used Tear-Gas shells were fired in artillery pieces or
released from canisters in the front line Releasing gas after explosions were not
effective The explosion dispersed the gas too much
making it not potent enough to do any damage
Not until the Battle of Verdun in 1916 did the explosive to gas ratio was perfected
How was Poisonous Gas Created and Used?

A makeshift German gas laboratory near the front
1,200,000 people were gassed in World War 1 91,200 of which died
Forced enemy to invent protection against the gases Caused enemy to not properly follow orders Not used in World War 2 Use of poisonous gas was banned by Germany in 1925
