Jeremiah Denton was a commander in the United States Navy during the Vietnam War when he was shot down, injured, and then taken prisoner by the North Vietnamese. Denton endured torture and solitary confinement as a POW at the hands of his captors, but he remained incredibly resilient during his almost eight years of captivity. Denton's resilience is most evident in a 1966 televised interview he was forced to partake in by his captors, in which he managed to bravely defend his country while simultaneously blinking the word "torture" in Morse code.
Luckily for Denton and other prisoners of war, the United States picked up on his message, but the Vietnamese did not. Due to his ingenious idea to convey this daring message in an extremely bold way, the United States was able to confirm that the Vietnamese were, in fact, torturing American prisoners of war. Although Denton remained in captivity for many years afterward, his message was crucial in alerting the United States to what was really happening overseas.
