Sorry myself for not being more clear but I didn't think that I had to repeat it three times ? Whoa ! How/when/where did you exaggerate up from John Dudek's source, which was talking about a few partial companies on anti-sabotge sentry duty, mostly in Honolulu, to an entire US regiment ? More specifically, for the night of Dec.6-7'41, his 25th Infantry Division Association: Pearl Harbor only actually lists: - just 30 men of Company B, 65th Engineer Battalion at Kaneohe NAS - 98 of the 128 men of Company A, 27th Infantry at Fort DeRussy in downtown Honolulu - some part of Company B, 27th Infantry was also on anti-sabotage sentry duty in downtown Honolulu. - some part of Company C, 27th Infantry was on anti-sabotage duty on the Honolulu waterfront and over to Fort Shafter. - some part of Company H, 35th Infantry seems to have been posted somewhere in the hills of Oahu, preparing for a coastal highway truck patrol, which was cancelled. Hardly a US regiment in total. At best this totals to 30 + 98 + 128 + 128 + 128 = 512 lightly armed men, in NOT even battalion strength, to cover the 608 square miles of a night time, peacetime Oahu. Less than 1 man per square mile, IN THE DARK ? And ONLY 30 of those were (at breakfast) in the Kaneohe Bay area. Not even on anti-sabotage sentry duty. Surely, AT SOME POINT IN TIME, some American defender is going to wake up and realize that the Japanese have invaded Oahu and WILL indeed try to sound an alarm. Will he have access to a working radio that he knows how to operate or just to telephone lines already cut in the darkness by the IJA invaders ? The questions remains, in light of the historically SLOW responses of Oahu's US defenders, how many Japanese infantry will already be ashore and just how far inland, when that alarm is finally sounded ? Will it actually be believed or will more hours be wasted in confirming such unbeleievable news ? When have we ever been talking at all about a land assault on Pearl Harbor ?. Since these Commands were under the control of the US Army on Oahu, I forward for your consideration, the following: For the Coastal Artillery Command which is confirmed by Thus twice confirming that Oahu's defensive coastal artillery (and US Army mobile artillery too for that matter) was totally blind to any target over the horizon or on the other side of Oahu's mountains, on the morning of Dec.7'41. Last but not Least, for the USAAF all from Vol. #7 of Pearl Harbor Attacked It seems to me that those who should have been watching for an offshore enemy on peacetime Oahu weekends, sure weren't.
