When we picture World War II, the usual suspects—Germany, Britain, the United States, the Soviet Union, and Japan—dominate the conversation. Yet the conflict was truly a global affair, and many nations played crucial roles that rarely make the headlines. In this roundup of the 10 underappreciated countries, we shine a light on the surprising ways these nations helped shape the outcome of the war.
Why These 10 Underappreciated Countries Deserve Recognition
10 Australia Fired The First Allied Shot
On the crisp morning of September 4, 1939—just a day after Britain declared war on Germany—a vessel drifted past Point Nepean’s coastal fort. When the garrison demanded identification and the ship remained silent, the defenders feared a German incursion and, in a flash of nerves, fired a warning round across its bow. Many historians now regard that as the very first Allied shot of the Second World War.
The incident itself is modest, especially since the ship turned out to be an Australian merchantman, not an enemy. The real curiosity lies in the gun battery’s pedigree: that same emplacement also delivered the opening Allied volley in World I, a neat coincidence that ties two great conflicts together.
Australia’s involvement didn’t stop there. By war’s end, the nation had sacrificed 27,000 of its sons on distant battlefields, a testament to its commitment far beyond that inaugural warning shot.
9 Largest Navy On Earth
At the war’s outset, Canada resembled a quiet suburb: a population of roughly 11 million, a modest fleet of fifteen ships, and an air arm of just 235 pilots. It seemed far from a major combatant.
However, the German onslaught in Poland sparked a rapid transformation. Within ten days, Canada poured $20 million into its defence industry, training nearly 50,000 pilots, constructing 800,000 trucks, launching 471 naval vessels, and producing 16,000 aircraft. In total, 730,000 Canadians answered the call to arms.
These efforts earned Canada a reputation as a premier air‑training partner for Britain and, astonishingly, placed its navy as the third‑largest on the planet by the conflict’s conclusion.
8 India Had The World’s Largest Volunteer Army
When the British Empire called upon its Indian subjects, an astonishing 2.5 million men stepped forward, creating the largest all‑volunteer army the world had ever seen. Not all marched to front lines; many bolstered factories, guarded railways, or manned anti‑aircraft batteries.
Those who fought made a decisive impact. The famed Fourteenth Army—a mixed brigade of British, Indian, and African troops—stormed back into Burma, turning the tide against the Japanese. By war’s end, thirty Indian soldiers had earned the Victoria Cross, the highest British gallantry award.
7 Malays Fought England’s Last Stand In Asia
In 1942, Japanese forces surged toward Singapore, a linchpin of British power in Asia. While the British expected their own troops to hold the fort, it was a Malay unit under Lieutenant‑Colonel Adnan Saidi that became the final barrier at Opium Hill.
During the battle, a deceptive contingent of Japanese soldiers disguised themselves in British‑Indian uniforms attempted a surprise attack. Saidi’s men recognized the irregular four‑man marching formation—unlike the British three‑file standard—and opened fire, thwarting the ruse.
The Japanese, enraged, launched a full‑scale assault. Saidi’s fighters fought tooth‑and‑nail, exhausting ammunition and resorting to bayonet combat. All but one fell; the Japanese eventually overran the hill, but the Malays’ valiant stand became a symbol of fierce resistance.
6 Switzerland Wasn’t Entirely Neutral
Switzerland’s famed neutrality didn’t translate into passivity. Determined to keep the war at bay, the Swiss air defense actively protected their skies, shooting down eleven German aircraft that strayed into their airspace en route to France.The German government demanded an apology, threatening retaliation. The Swiss, however, rebuffed the complaint and insisted the violators cease using their territory.
Neutrality proved fragile. Allied bombing raids occasionally missed their intended German targets, striking Swiss towns instead. One U.S. raid claimed about a hundred civilian lives. By war’s end, the United States had paid more than $14 million in reparations for the accidental bombings.
5 Kenya Fought Against Both Italy And Japan
Nearly 100,000 Kenyan volunteers enlisted in the King’s African Rifles, comprising roughly a third of Britain’s African forces. They first repelled an Italian invasion of East Africa, then pressed on to Madagascar and the Burmese front, battling both Axis powers.
Racism shadowed their service: African troops earned lower pay and were barred from commanding positions. Yet they turned prejudice to their advantage. One Kenyan recounted how soldiers would masquerade as cannibals to intimidate Japanese opponents, a psychological tactic that unnerved the enemy.
4 Poland Broke Enigma First
Alan Turing often receives the lion’s share of credit for cracking the German Enigma cipher, but the first breakthrough came from Polish mathematician Marian Rejewski. As early as 1932, Polish cryptanalysts, aided by French‑obtained documents, succeeded in replicating the Enigma machine.
Rejewski’s work yielded the first functional copies of the device and allowed Polish codebreakers to read German communications. When the Nazis discovered their code was compromised, they dramatically increased its complexity, stalling the Polish effort.
Anticipating a German invasion in 1939, the Polish team shipped all their discoveries to Britain, laying the groundwork for the later Allied successes that Turing and his colleagues would achieve.
3 Finland Held Off An Invasion Of One Million Russians
In 1939, the Soviet Union demanded several Finnish islands, and when Finland refused, the Red Army unleashed a massive offensive, deploying roughly one million troops—outnumbering the Finns three to one.
Finland appealed to Britain and France for assistance, but received none, forcing the nation to confront the Soviet onslaught alone. Despite the odds, Finnish forces inflicted heavy casualties, killing about 320,000 Soviet soldiers while sustaining roughly 70,000 losses themselves.
Although Finland ultimately ceded territory, its fierce resistance dealt a crippling blow to the Soviet war machine and demonstrated that a small nation could stand up to a superpower.
2 Almost Every Soldier From One Armenian Town Earned A Medal
Deep in the Armenian highlands lies the modest mountain village of Chardakhlu. Of the 1,250 residents who were conscripted into the Soviet army, an astonishing 853 returned bearing medals, twelve rose to the rank of general, and seven earned the title Hero of the Soviet Union.
Two natives rose to the pinnacle of Soviet military leadership: Hamazasp Babadzhanian, who became chief marshal of armored troops, and Ivan Bagramyan, who achieved the rank of marshal of the Soviet Union.
By war’s end, Chardakhlu boasted one of the most highly decorated cohorts in the USSR—most of its men wore medals proudly, while the rest made the ultimate sacrifice.
1 Russia Killed Eight Out Of Ten German Soldiers
Russia’s role in World II is far from obscure, yet many underestimate its sheer scale. While the United States often receives praise for turning the tide, the Soviet Union shouldered the lion’s share of the German death toll.
Statistics show the USSR accounted for roughly 80 percent of all German casualties throughout the war; if we consider only the period after 1941, that figure climbs to an astonishing 95 percent.
A substantial portion of this devastation unfolded during the Battle of Stalingrad, where Soviet troops routinely eliminated up to 20,000 German soldiers per day. Moreover, nine of the ten deadliest snipers of the conflict hailed from the Soviet ranks.
In short, the Soviet Union didn’t merely contribute; it overwhelmingly annihilated the German war effort, cementing its place as the decisive force on the Eastern Front.
