The Philippines observes Day of Valour, Araw ng Kagitingan, on April 9

Araw ng Kagitingan (day of valor) commemorates the heroism of Filipino and American soldiers at the Battle of Bataan. The Bataan Peninsula and Corregidor Island were the only remaining Allied strongholds in Southeast Asia. Their relentless fighting delayed the Japanese invasion over the Pacific until the Fall of Bataan on April 9, 1942. Approximately 76,000 Allied soldiers surrendered, the largest in both American and Philippine military histories. These prisoners of war were then forced into the 140-km Death March.
