Never Surrender: The Ed Ramsey Story (2016)

Ramsey...found himself in charge of the elite 26th Calvary Regiment in the Philippines, where he was leading a 'Gunga Din'-type existence playing polo with other officers until Japanese troops marched through Manila. He subsequently led his storied offensive in the Philippine jungle, and in 1942 he joined the Filipino resistance, ultimately commanding more than 40,000 guerrilla fighters and enduring severe malnutrition and a slew of tropical diseases.
