THE WORLD'S ADVANCE 



WARFARE WITH GAS CLOUDS AND BOMBS 



A German trench mortar used especially for 

 hurling of gas bombs, captured by the French, 

 asphyxiating gas employed by the Germans is either 

 released into the air and blown over the enemy's 

 lines by the wind, or is placed in bombs and shot 

 from special mortars.

 fantry wearing special res- 

 pirators for protection against 

 German gas attacks. 



Type of respirator worn by the French soldiers and 

 which forms an effective protection against the 

 asphyxiating gas clouds employed by the Germans. 

 The respirators are very simple in design, yet their; 

 use enables the British and French infantrymen to 

 hold their trenches in the face of a gas cloud and 

 repel the German infantry attacks that generally 

 follow.
