Leland Calvert (b. 1913) was a sergeant from San Antonio, Texas. In April 1942, he was the focus of an Associated Press story about the dire situation in the Philippines, specifically the complete lack of food and essential supplies for the several American and Filipino troops stationed on the Bataan Peninsula. Calvert had eaten a few wild creatures, such as snake and frogs, to stave off starvation. He'd also had several diseases, such as dysentery, malaria, beriberi, and dengue fever. The only disease he didn't have was scurvy.
