Yap's Role in the Saipan Campaign, June 1944

When I was looking up stuff about Yap, Micronesia, for a recent post, I came across a very informative website, with both photographs courtesy of the Micronesian Seminar, and even video, about the bombing of Yap during the Pacific War, about which I heard many stories during my time there in 1974. I have corrected obvious spelling errors in the following extract.
At dawn, on the 15th of June 1944, American amphibious forces swept into Saipan to begin the hard ground fighting that was to bring the Japanese homeland within range of our Superfortresses. For more than two weeks prior to the landings, Thirteenth Air Force Liberators, based on Los Negros, had been pounding Truk to neutralize the strategic Japanese base and to prevent the enemy from reinforcing Saipan by air.

A large Japanese task force, estimated at 40 ships or more, was sighted some distance north of Yap Island, on the 19th of June 1944. Carrier planes from this task force lashed out at the powerful units of the United States Pacific Fleet which were then supporting Allied ground forces on Saipan. The conflict that followed was the first major battle between elements of the Japanese and United States fleets in nearly two years. As at Midway, two years earlier, all of the offensive action was by carrier-based aircraft. By the time the Japanese fleet broke off the engagement, U.S. Task Force "58" had destroyed nearly 400 enemy aircraft and had sunk or damaged 14 Japanese ships.

Liberators of the Thirteenth Air Force were called upon to reach out more than 1,000 statute miles from their Los Negros base to hit Japanese warships that might seek refuge or fuel in Yap Harbor. On 22 June, 33 Liberators were over Yap in the longest mass mission the Thirteenth had yet flown. Trained eyes peered down on the harbor far below. There were no warships to be seen. The heavies wheeled and made their run on the secondary target, Yap Airdrome. Their 33-ton bomb load struck the runway and the dispersal areas with devastating effect.

The Japanese were caught completely by surprise; not a single one of the more than 40 planes on the ground was able to take off and fly into the air. Nineteen enemy planes were definitely destroyed, and 15 were damaged; the runway was cratered and rendered unserviceable.

For six consecutive days after the raid of the 22nd of June, the Liberators blasted Yap, keeping the runway unserviceable and preventing its use in ferrying planes from the Philippines to the Marianas to aid the hard-pressed defenders of Saipan.
