I am reading the book entitled "Military Errors of World War Two" by Kenneth Macksey, ISBN 1-85409-199-9. In the chapter entitled "Suicidal Impulses" page 223:
footnoteHalsey was far better informed than his enemies who were groping throughout. When he made his crucial decision at about 2000 hrs on the 24th to lead the entire Third Fleet against Ozawa in the north, he was beyond doubt aware, through Special Branch which processed Ultra, that Ozawa's Force was a decoy with the task of tempting him away from the San Bernardino Strait so as to leave it completely unguarded.
So, my question is, did Halsey know from Magic intercepts that Ozawa was a decoy force only and posed no real threat? I don't think I have ever read this before and I tend not to believe it after reading several other chapters in this book that are really bad as far as factual history goes.When writing the official history Morison, for security reasons, was forbidden from mentioning the assured SIGINT factor, with the result that his criticism of Halsey was a lot less trenchant than many thought it should have been.
Also he states on page 233 while discussing the effectiveness of the Kamikaze attacks:
So, if I read this correctly the Japanese from the first Kamikaze attacks in late October to 12 December sank seven of our heavy carriers and damaged seven others. . .is that true? Seven Fleet Carriers sunk by Kamikaze in about 6 weeks??At far lower cost in machines and men, they had, by 12 December, hit and damaged seven heavy carriers and sunk seven and damaged 23 other ships-with more to come.
Thanks in advance
Mike
