George Mallory’s final letter to his wife before his ill-fated attempt to summit Mount Everest in 1924 conveys a mix of optimism and the harsh realities of the expedition. Mallory expressed high hopes despite acknowledging the slim odds of success (50 to 1 against them) and described the challenging conditions and exhaustion faced by the team. Ultimately, Mallory’s fate remains a mystery, as his body was discovered far below the peak, while his climbing partner Andrew Irvine’s remains have never been found.
