The Second Battle of Ypres was the first poison gas attack of the war. It was made by the Germans, and chlorine gas was used. This battle also inspired John McCrae's poem 'In â¦ Flanders Field'.In addition, Canadian troops were proved capable in their success in holding the line regardless of the gas.he second battle of Ypres (April 22nd-May 25th, 1915) was the first major use of gas (the first was on the eastern front), which caused all to develop a gas mask, and led to the use of gas to never be effective, or a surprise.
