After the attack on Pearl Harbor on December 7, 1941, the Japanese sent their planes to attack the Philippines, launching major air raids throughout the country. The bombings resulted in the destruction of the Batangas Airport located in Batangas City, of which nothing remains today. Batangas was also a scene of heavy fighting between the Philippine Army Air Corps and the Japanese A6M Zero Fighter Planes. The most notable air combat battle took place at height of 3,700 metres (12,000 ft) on December 12, 1941 when 6 Filipino fighters led by Capt. Jesús Villamor engaged the numerically superior enemy of 54 Japanese bombers and fighter escorts which raided the Batangas Airfield. Capt. Jesús Villamor won the battle, suffering only one casualty, Lt. César Basa who was able to bail out on a parachute as his plane was shot down only to be strafed by machine-gun fire from the A6M Zeroes.
