AP story on recovering the Japanese sub gave a definitely wrong impression when it states:
"But the military base and ships were not immediately placed on alert, which would have prepared the United States for the ensuing attacks.
‘They notified the Navy headquarters (in Washington) and they needed confirmation before they would act,’ Martinez said. `Remember, there was nothing to tell them that it was a Japanese submarine. It could’ve been anybody and it could’ve been friendly.’
That doesn’t jive with a well-researched account done two years ago. According to Day of Deceit by Robert B. Stinnett (2000) “Free Press”
“During the early hours of Dec. 7, crewmen of a minesweeper, USS Condor , sighted the periscope and conning tower of a Japanese submarine…At 3:42 a.m., a fluorescent wake neat the Condor 's port bow caught the attention of Ensign Robert McCloy. He focused his binoculars on the wake and discovered that it was caused by a periscope that was moving at about nine knots and stirring the waters to a brilliant glow…Two crewmen standing watch alongside him confirmed the sighting and realized it was not a US sub; they were forbidden to be submerged in the entrance channel and adjacent waters, which were in a Defensive Sea Area, a ten-square-mile zone where submerged vessels were prohibited. Admiral Kimmel had previously issued standing orders directing navy vessels to attack submerged vessels in the zone.”
The Condor then alerted the destroyer Ward , but they couldn’t find it at which point her captain advised that a sub had been sighted in the channel. While they were vainly searching, two midgets had slipped into the harbor as the antisubmarine net had been retracted expecting another Navy vessel.
The captains of the Ward and the Condor conversed in plain language “so that other warships and fleet command posts would be instantly alerted to submarine contacts.” They were acting on "orders issued by Admiral Kimmel months earlier:
‘When American warships definitely know an enemy submarine is in the area then they are to broadcast the information in plain language in order to sound the alarm and alert the proper people and put them in a state of readiness.’
The 15-min. radio exchange did reach the Communication Watch Office of the 14th Naval District. But the watch officer, Lt. Oliver Underkofler, was asleep and did not hear the loudspeaker report of the sub sighting."
In subsequent action, the Ward sank another sub as it tried to follow the Antares in to the harbor. Lt. Commander William Outerbridge then "radioed an alert in plain language over the special frequency: ‘We have dropped depth charges upon subs operating in Defensive Sea Area.’ Believing his first message wasn’t strong enough, he sent another: ‘We have attacked, fired upon, and droped depth charges upon submarine operating in Defensive Sea Area.’ These plain-language messages woke up Underkofler, who rushed to Ward’s report to the senior duty officer for the 14th Navy District, Lt. Cmdr. Harold Kaminski. Now it was up to Kaminiski to inform Rear Admiral Claude Bloch, the commandant of the 14th Distrct and the naval officer charged with protecting the fleet while in anchor at Hawaii. Kaminski received a busy signal when he dialed Bloch’s aide. He then called Admiral Kimmel’s office at the Submarine Base–a mile away–and reached the assistant duty officer, Lt. Cmdr. F. L. Black
