   The Battle of Messines Ridge, 1917
   As described in Darling, the Battle of Messines Ridge began with the explosion of nineteen underground mines. Rocks and dirt blasted high into the air. The earth shook and heaved. The explosions killed about ten thousand German soldiers. The noise and force even shocked the Allied soldiers (British, French, Australians), since the mines had been kept a secret.
   Germany had controlled Messines Ridge, located in Belgium, since 1914. With the help of planes and tanks, the Allies were able to advance to the German front lines and capture the area. It was a bloody battle and a hard-fought victory for the Allies. It is estimated that over 42,000 lives were lost.
   Interesting Facts about the War
   World War I lasted from 1914 to 1918.
   It was named The Great War because it was the first war to use massive weapons such as tanks and two-ton howitzers.
   “Bomb” is what the British call a hand grenade.
   A British soldier was called a “Tommy.”
   Each soldier carried a ten-pound rifle, a bayonet, sixty pounds of ammunition, a digging tool, and a gas mask. Survival gear might also consist of eating utensils, bootlaces, a blanket, a razor, and iron rations.
