In any event, the battle of the
Philippine Sea, better known as the Marianas Turkey Shoot. In the
course of two days, the Japanese lost something of the order of 375
aircraft, together with what was left of their carrier fleet. That
effectively ended any challenge to American air power in the
Pacific.
This explains why, with effect from
June 1944 onwards, the Japanese had very little air cover over the
Philippines, so the US Fleet could more or less strike wherever they
wanted. This they proceeded to do, whenever and wherever it suited
them, and on 22 September 1944, aircraft from Task Group 38 hit
Japanese ships in Manila Bay.
In order to try and protect what
they had left, some of the Japanese ships were ordered out of Manila
to anchorages in the Busuanga Channel, where they thought would be
safe as they were out of range.
By about 5 am on the morning of the
24th, the carrier fleet was in position, about 50 miles north-east
off the cost of Samar, they turned into the wind and the first wave
of aircraft were launched about 0530.
How did Halsey know where the fleet
had gone? There is an anecdote about how the ships were identified
at Coron; the story is that there was a photo reconnaissance flight
that passed overhead and took pictures of what were thought to be
islands....see: [ History
