1. Germans were the first to use flamethrowers in WWI. Their flamethrowers could fire jets of flame as far as 130 feet (40 m).
2. More than 65 million men from 30 countries fought in WWI. Nearly 10
million died. The Allies (The Entente Powers) lost about 6 million
soldiers. The Central Powers lost about 4 million.
3. Nearly 2/3 of military deaths in WWI were in battle. In previous conflicts, most deaths were due to disease.
4. “Little Willie” was the first prototype tank in WWI. Built in 1915, it
carried a crew of three and could travel as fast as 3 mph (4.8 km/h).
5. During WWI, British tanks were initially categorized into “males” and
“females.” Male tanks had cannons, while females had heavy machine guns.
6. In August 1914, German troops shot and killed 150 civilians at Aerschot.
The killing was part of war policy known as Schrecklichkeit
(“frightfulness”). Its purpose was to terrify civilians in occupied
areas so that they would not rebel.
7. Artillery barrage and mines created immense noise. In 1917, explosives
blowing up beneath the German lines on Messines Ridge at Ypres in
Belgium could be heard in London 140 miles (220 km) away.
8. The Pool of Peace is a 40-ft (12-m) deep lake near Messines, Belgium. It
fills a crater made in 1917 when the British detonated a mine
containing 45 tons of explosives.
9. Tanks were initially called “landships.” However, in an attempt to
disguise them as water storage tanks rather than as weapons, the British
decided to code name them “tanks.”
10. During WWI, the Spanish flu caused about 1/3 of total military deaths.
