World War 1: Facts and Information

Here are some facts about World War 1

  • World War 1 began on July 28, 1914 and lasted until November 11, 1918. Differences in foreign policies were to blame, although the immediate cause was the assassination of Austria’s Archduke Ferdinand. (Follow this link to learn more about how World War 1 started)

  • The two main sides were the Allies, which included France, Great Britain and Russia; and Germany and Austria-Hungary. In total, 30 countries were involved in the conflict. Italy, once part of the Triple Alliance with Germany and Austria-Hungary, fought on the side of the Allies.
  • King George V (Great Britain), Kaiser Wilhelm II (Germany) and Tsar Nicholas II (Russia) were cousins, and grandchildren of Queen Victoria.
  • Soldiers fought largely in trenches during the war, and thousands suffered from stress, known as shell-shock.Β  The British and French trenches were often squalid, whereas the German trenches were almost luxurious in comparison, with bunks and decent cooking facilities. (Click here to learn more about life in the trenches)
  • By the end of WW1, over 9 million soldiers had been killed, and another 21 million wounded. Over a million soldiers were killed in the infamous Battle of the Somme alone, including about 30,000 in just one day.
  • Around 11 percent of the population of France was killed or wounded during the war. About 116,000 Americans were killed, even though the US was only in the war for about 7 months.

World War 1

  • During World War 1, dogs were used to carry messages in capsules attached to their body. Dogs also carried and placed telegraph wires in important areas.
  • Pigeons were also used during the war. About 500,000 pigeons were regularly dropped into enemy lines by parachute, and then sent back with messages.
  • On Christmas Eve, 1914, both sides declared an unofficial truce and sang Christmas carols to each other. Football matches were played in no-man’s land (the area between the German and British) trenches, and German and British soldiers exchanged food and souvenirs. The ceasefire was known as the Christmas Truce. The following Christmas, sentries on both sides had orders to shoot any soldier who did this.
  • Cannons and artillery were often extremely loud. In 1917, the explosives used to destroy a bridge in France could be be heard over 130 miles away in London.
  • Many new weapons were invented or first used during World War 1. Big Bertha was one of the most famous; it was a 48 ton gun capable of firing a shell over 9 miles. It took 200 men several hours to assemble the gun.
  • Tanks were so called because of early attempts to disguise them as water tanks. They were also known as male and female tanks; male tanks had cannons and female tanks had machine guns.
