Mortars of this type have proved very effective throughout the present war. The Allies have been using one known as the Schneider siege mortar, which they have found to be as effective an agent of destruction as the famous German 42 centimeter guns. This gun is being used in great numbers on the Western front. It hurls a projectile weighing nearly a ton a distance of ten miles, and can be fired three times a minute. Note the recoil mechanism on the under side of the gun and note also that the entire battery is situated in a pit, concealed and protected from the guns of hostile fleets |
