On August 5, 1923, Henry Sullivan set out from the beach of Dover to be the first American to swim across the English Channel. The next day he accomplished his goal when he arrived on the coast of France. It was his seventh attempt.
Sullivan’s historic swim was an unparalleled testament to raw physical endurance and stubborn grit, taking a grueling 26 hours and 50 minutes to complete. The English Channel was widely considered to be an unbeatable natural barrier, characterized by bone-chilling 50-degree water temperatures, unpredictable shifting tides, and thick swarms of stinging jellyfish. Because of the brutal head-currents and relentless waves that repeatedly pushed him off course, Sullivan was forced to swim an estimated total of 56 miles just to cross the 21-mile strait, fighting off extreme hypothermia and absolute physical exhaustion to secure his place in aviation-era athletic lore.
