Note 14 — Chapter VI · The Japanese Reaction

Since without the participation of our Combined Fleet there was no possibility of the land-based forces in the Philippines having any chance against your forces at all, it was decided to send the whole fleet, taking the gamble. If things went well, we might obtain unexpectedly good results; but if the worst should happen, there was a chance that we would lose the entire fleet. But I felt that that chance had to be taken.... Should we lose in the Philippines operations, even though the fleet should be left, the shipping lane to the south would be completely cut off, so that the fleet, if it should come back to Japanese waters, could not obtain its fuel supply. If it should remain in southern waters, it could not receive supplies of ammunition and arms. There would be no sense in saving the fleet at the expense of the Philippines.14
