The Allies mounted more gas attacks than the Germans in 1917 and 1918 because of a marked increase in production of gas from the Allied nations. Germany was unable to keep up with this pace despite creating various new gases for use in battle, mostly as a result of very costly methods of production. Entry into the war by the United States allowed the Allies to increase mustard gas production far more than Germany. Also the prevailing wind on the Western Front was blowing from west to east, which meant the Allies more frequently had favourable conditions for a gas release than did the Germans.
