Chlorine gas was first used by the Germans at the Second Battle of Ypres in April 1915, killing hundreds of French troops.
The British also deployed chlorine gas, and later developments in the war included the deadlier phosgene and mustard gas, which blinded those it came in contact with
By 1917 poison gas could be delivered with greater precision by chemical shells and mortars, and there were an estimated one million gas casualties on all sides throughout the war.
Britain introduced better fighters such as the SE5 and Sopwith Camel in 1917, and it was the latter which mostly likely claimed the life of the Red Baron when he was shot down in April the following year.
Originally called “land battleships”, then “thingum-a-jigs”, tanks were developed on the orders of Winston Churchill and first deployed on the Somme battlefield in September 1916
Their armour would be impervious to machine gun fire, and their tracks would be able to cross trenches and barbed wire entanglements.
