Military Units During WWII

Clark and its subordinate airfield at Del Monte were the only airfields in the Philippines capable of heavy bomber operations at the outbreak of World War II.

News of the Pearl Harbor attack was received at about 3 am on 8 December in the Philippines. According to the previously-agreed upon plan, if hostilities were to break out, an attack on Japanese bases in Formosa was to be immediately carried out by the 19th Bombardment Group's Fortresses. On 8 December, there were 35 USAAC B-17s in the Philippines, with two squadrons at Clark Field on Luzon with a total of 19 planes, and two squadrons at Del Monte on Mindanao 500 miles to the south with the other 16 B-17s.

For reasons which are still unclear even today, the planned raid on Formosa was delayed. Instead, in order to prevent them from being destroyed on the ground by a Japanese air attack, all flyable B-17s based at Clark Field had been ordered into the air and to patrol the waters around Luzon. In the meantime, General Lewis H. Brereton, General MacArthur's air commander, finally got approval to carry out the strike against Japanese bases on Formosa, and the B-17s were recalled to Clark. When the Fortresses returned to Clark, three of them were equipped with cameras for reconnaissance and the remainder were loaded up with 100-lb and 300-lb bombs in preparation for the planned mission to Formosa.

The three reconnaissance B-17s were taxiing out for the initial photographic mission to Formosa when about 200 Japanese aircraft struck. Unfortunately, all the P-40 fighters had been recalled for refuelling and were on the ground. . At the end of the day's action it was apparent that the Japanese had won a major victory. The effective striking power of Far East AF had been destroyed, the fighter strength had been seriously reduced, most B-17 maintenance facilities were demolished, and about 80 men were killed. The sole surviving B-17 had not taken off on the morning alert, and had been taken up in the air while the rest were being prepared for the Formosa raid. The Fortresses at Del Monte 500 miles to the south were out of range of the Zeros from Formosa and were left untouched.

At Clark Field, three or four of the damaged B-17s were put back into service. They were joined by the B-17s from Del Monte. By 9 December, reconnaissance missions were being undertaken by the 19th Bombardment Group in search of the Japanese fleet. Also, the 17th Pursuit Squadron (Interceptor), 24th Pursuit Group (Interceptor), based at Nichols Field were transferred to Clark with P-40's.

On 10 December, a Japanese convoy was spotted, and five B-17s were dispatched. This was the first American bombardment mission of World War II. No fighter opposition was encountered, and some hits were recorded on the transports.

That same day, a B-17C piloted by Captain Colin P. Kelly dropped bombs from high altitude on what the crew thought to be a Japanese battleship. Hits were recorded, and a tremendous explosion was observed. Kelly's plane was immediately pounced upon by Zeros, one of which was flown by Saburo Sakai, who was later to become a famous ace. Kelly guided his heavily-damaged plane back towards Clark Field. He ordered the crew to parachute to safety, but before Kelly himself could leave, the aircraft exploded and Kelly was killed.

When the surviving crew was questioned, the report was flashed out that they had sunk the Japanese battleship Haruna, and the mission was hailed as a great victory. Captain Kelly was posthumously awarded the Distinguished Service Cross by President Franklin Roosevelt for his heroism, and was written up in glowing press reports. However, information revealed in the immediate postwar years revealed that the Haruna was nowhere near the area at that time and that the ship most likely struck was the cruiser Ashigari, and it was only fairly lightly damaged by the attack.

On 12 December, about 100 Japanese aircraft again hit Clark. The airfield is severely damaged and plans were made to evacuate the facility. On the 19th, the air echelon of the 93d Bombardment Squadron (Heavy), 19th Bombardment Group (Heavy) were transferred from Clark to Batchelor Field near Darwin, Northern Territory, Australia with B-17's. The ground echelon is attached to the 5th Interceptor Command (Provisional) and sent to fight as infantry on Luzon and Mindanao Islands. On Christmas Eve, HQ 19th Bombardment Group (Heavy) and the air echelon of the 28th Bombardment Squadron (Heavy) were transferred from Clark to Batchelor Field with B-17's. The ground echelon of the 28th were dispatched to fight as infantry on Luzon and Mindanao.

The remaining aircraft and personnel at Clark were evacuated to Australia by 31 December 1941. The base was overrun by Japanese forces less than a week later in early January 1942.
