Harrowing Facts About WWI


“In Britain and Europe, no event is less forgotten than WW1, or 'The Great Battle,' as it was called until 1939” -Michael Korda

WW1 took place between 1914 and 1918 and is known as the “First World Battle”, “The Great Conflict”, and “The Battle to End All Wars”. It was a global conflict originating in Europe and involved more than 70 million army personnel. Over 16 million deaths resulted from the conflict, including 9 million army people and 7 million civilians. It was one of the largest and deadliest wars in history and caused major political change in the countries that were involved, and some of the unresolved issues from the conflict contributed to WWII just two decades later. Here are 42 harrowing facts about the Great Battle.


42. Jet Flames

Modern flamethrowers were first used in WWI by the German forces in an attack against British at Hooge in Flanders. The earliest flame throwers dated back to the 5th century, but the Germans refined the designs that were used in the battle.

41. Trigger for Conflict

The execution of Archduke Ferdinand was not the sole cause for WWI, but it was considered to be the trigger that started it.

The execution was orchestrated by a group of Serbian nationalists who lived in the Balkan territories belonging to Austria-Hungary, and who felt that they should become part of the Serbian nation. Austria Hungary blamed the Serbian government, and once they were assured of Germany’s support, declared battle on Serbia. Within a week, multiple European countries had entered the conflict, officially launching WWI.

40. Alliances

One of the reasons that so many European countries entered into WWI were the mutual defense agreements that had been made between various countries. The treaties stated that if one of the countries in the treaty were under attack, the other countries were obligated to defend them.

The conflict began with Austria-Hungary attacking Serbia, and a chain reaction began. Russia entered to defend Serbia. Germany entered to defend Austria-Hungary. France was allied with Russia, Britain was allied with France and Belgium, and Japan was allied with Britain. Eventually, the United States entered the battle and fought with the allied countries.

39. Battle Poem

In Flanders Field was written in 1915 by a Canadian officer and surgeon named John McCrae, who wrote it in honor of his friend who lost their lives during the Second Battle of Ypres.

The poem also helped make the red poppy a symbol of remembrance.

38. German Atrocities

In August 1914, the German army orchestrated a mass execution of Belgian civilians in Liege. The inhabitants were rounded up from the nearby villages and shot. Any who survived the execution were ended with bayonets. There were a few reasons for the massacres. First, they were retaliation for setbacks suffered by the German army during their invasion of Belgium.

Second, much of the German army believed that the locals were actually civilian snipers who were attacking them. Third, the German army were executing a battle policy known as Schrecklichkeit, meaning frightfulness, which was intended to frighten the civilians in the occupied areas to prevent rebellion.

32. Facing Danger

At the start of WWI, journalists were banned from the frontline because the Government insisted on controlling what information came out about the conflict.

23. Entering the Fray

When WWI broke out in 1914, then US President Woodrow Wilson promised to maintain a neutral position in the conflict.

However, Britain was one of their closest trading partners, and when American ships traveling to Britain were damaged or destroyed by German mines, relations with Germany became tense. In 1917, Germany resumed unrestricted battle in conflict-zone waters, resulting in the US breaking diplomatic ties. Just a few hours later, Germany sunk the American liner Housatonic, and the process of preparing for battle began.

22. Trench Battle

Trench battle was a style of fighting during WWI that involved opposing armed forces attacking, counterattacking, and defending from trenches dug into the ground. The trenches would make it virtually impossible for forces to advance and could extend for several miles.

Russia also gave up a large portion of agricultural land, over 80% of its coal mines, and half of its other industries.

14. The Man in the Copper Mask

Repairing the soldier’s injured faces was virtually impossible in the days before plastic surgery and transplants, so the solution most often used was to create masks. Some of the best masks were made by sculptor Anna Coleman Ladd who would take plaster casts of a soldier’s face and attempt to re-create the missing part of the face. She would make the masks out of copper and paint it to match the skin while it was being worn.

The mask would be tied to the head with a string or hung from eyeglasses. Eventually, Ladd was able to create the masks from images or photos. In 1925, she was made a Chevalier (knight) of the Legion of Honor for her work.

As with any battle, there were a number of dissenters who refused to cooperate with the army and fight in WWI.

Advertisement

Of the men who were drafted in England, approximately 16,000 became conscientious objectors to the conflict. In Britain, many of these men were either sent to lock up or assigned to civilian jobs. Some were handed white feathers as an implication of cowardice, and as an attempt to shame them into fighting.

10. Food Price Fixing

Prior to WWI, Edwardian society was one of lavishness and luxury for the wealthy classes, but during the early months of the battle that trend reversed as shortages came into play. Food prices rose drastically as stockpiling occurred and the newly formed Cabinet Committee on Food Supplies was forced to fix maximum prices for food.

At the same time as the price fixing was put in place, the luxury food demand experienced a major drop due to a lack of entertaining.

9. As Dark as the Middle Ages

Fuel also was in short supply during the battle, forcing Britons to dim the street lamps and put up blinds which were to be kept drawn at night.

Advertisement

These new laws led one lady to quip that by the end of the battle, Britain was “almost as dark as the Middle Ages". By 1915, coal was also in short supply, and newspapers began printing advice on how to save fuel while cooking or cook without it entirely.

8. Conflict to End All Wars

H.G. Wells was the first to use the term “The Conflict to End All Wars” to describe WWI. With casualties of up to 15 million people and the absolute destruction it caused, Wells, along with many others, hoped that it would teach the world that battle was not a solution for settling political conflict.

In the end, this hope pcroved idealistic, and less than three decades later, the world entered into another global conflict.

2. A Unlawful Offense

As shortages grew, rations also became stricter. Chocolate and candy sales halted entirely, horses, cows, and pigeons were rationed, and throwing rice at weddings became a unlawful offense.

The government advised people to “eat slowly” and “keep warm” so that they would need less food, but no suggestions on how to keep warm with limited fuel and no fat in their diet was offered.

1. Canary Girls

Both the staining color of their product and its hazard side effect of jaundice became a problem for the UK women who made TNT during WWI.

Advertisement

These women were called canary girls, because being exposed to TNT was bad, and it turned their skin the same orange-yellow color as the canary. Munitionettes was another nickname for the women. Despite the endearing nicknames, almost one in four canary girls lost her life from the hazard effects of their work.
