The free world watched as one by one countries across Europe surrendered to Hitler’s Axis forces. At 3:00 a.m. on October 28, 1940, a representative of the Axis forces arrived at the Greek prime minister’s residence and demanded Greece’s surrender.

The prime minister replied with one single word – Oxi – No.

A few hours later, the Axis forces descended on Greece, expecting that it would quickly fall, but the Greek resistance forced Hitler to change his plans. News of Greece’s victory flooded the radio airwaves and covered the front pages of newspapers around the globe. A grateful world celebrated – no one expected such a small nation to derail the seemingly unstoppable Axis forces.
