USS Ward’s Attack on a Japanese Midget Submarine at Pearl Harbor

From Congressional Investigation into the Pearl Harbor Attack, Part 36

(Exhibits of the Joint Committee)

Testimony of: Captain Willlam W. Outerbridge, Commanding Officer, U.S.S. Ward Before the Hewitt Inquiry

Adm. Hewitt: State your name and rank.

Outerbridge: William W. Outerbridge, Captain, U. S. Navy.

Hewitt: You were the Commanding Officer of the Ward on the morning of 7 December 1941?

Outerbridge: Yes, sir.

Hewitt: And during the early hours of that morning, you had several actual contacts with submarines? Is that so?

Outerbridge: Several actual contacts?

Hewitt: Well, reported contacts.

Outerbridge: Yes, sir. We had one alert and one actual contact and then later, after the attack, we had several outside.

Hewitt: There has been reported and logged the conversation which you had with the Condor along about 0520 Honolulu time and later there is in evidence and report of your actual attack on the submarine. Will you give me your story of the events of the morning, beginning with the report from the Condor about 0400?

Outerbridge: That doesn’t appear on this record, but she signaled us by flashing light that she believed she had seen an object that looked like a submarine proceeding to the westward, and I believe she had just come out and was sweeping, magnetic sweep out in the channel, but she said, “The submarine is standing to the westward.”

Hewitt: What was her location?

Outerbridge: She was in the channel, sweeping with her magnetic sweeps.

Hewitt: The approach channel to Pearl Harbor?

Outerbridge: Outside of the actual channel, between the reefs, but on the approach channel to Pearl Harbor.

Hewitt: Swept channel?

Outerbridge: Swept channel, yes, and we went to General Quarters and proceeded to her position, as close as we could get to her without fouling her sweeping gear, and then we stood to the westward, slowed to ten knots, and searched. It was a sonar search. We couldn’t see anything.

Hewitt: About what time did you get that signal?

Outerbridge: We got that signal about 0358, visual signal about 0358, and we searched for about an hour and didn’t find anything; so I got in contact with her again and asked her for a verification. Then she said this is in the record here. We asked her first, “What was the approximate distance and course of the submarine that you sighted?” and she said, “the course was about what we were steering at the time 020 magnetic and about 1000 yards from the entrance apparently heading for the entrance.” Well, I knew then that we had been searching in the wrong direction. We went to westward, and, of course, there was still doubt as to whether she had actually seen a submarine because there hadn’t been any other conversation, except by flashing light with us, and I wondered whether they were sure or not; so I did ask them, “Do you have any additional information on the sub?” and they said, “No additional information,” and I then asked them, “When was the last time approximately that you saw the submarine?” and they said, “Approximate time 0350 and he was apparently heading for the entrance.” Then we thanked them for their information and asked them to notify us if they had any more information and then we just kept on searching in our area, in the restricted area outside of the buoys. That was the end of this incident for the first search.

Hewitt: You made no report of that to higher authority?

Outerbridge: No, sir, I didn’t make any report of it.

Hewitt: What was your evaluation of that?

Outerbridge: Well, at the time I thought perhaps it wasn’t a submarine, because they didn’t report it. This conversation was taken over another circuit entirely. This is not in either his log or mine. They didn’t report it and I thought if he didn’t report it, he must not think it is a submarine. It was his initial report and I thought it may not be. It may have been anything; it may have been a buoy. Since then, I don’t believe it was a buoy. I believe the Commanding Officer of the Condor saw a submarine. I don’t know where he is. I think he was killed, killed in action. But at that time I didn’t know whether or not it was a submarine.

Hewitt: You say you think the Commanding Officer of the Condor was killed?

Outerbridge: I believe he was killed.

Hewitt: Do you remember his name?

Outerbridge: No, sir, I don’t know, but I met some people who told me about him.

Hewitt: Well, now about the later contact.

Outerbridge: The later contact I turned in again and was sleeping in the emergency cabin, as usual, and Lieutenant Goepner had the deck. He was a j. g. He called me and said, “Captain, come on the bridge.” The helmsman was the first one to sight this object and he saw this thing moving. It looked like a buoy to him, but they watched it and after they had watched it for a while, they decided probably it was a conning tower of a submarine, although we didn’t have anything that looked like it in our Navy, and they had never seen anything like it. I came on the bridge as fast as I could and took a look at it. I don’t know where it appeared to them at first, but at that time it appeared to me to be following the Antares in. The Antares had been reported to me and at that time I thought the Antares had been heading into the harbor. She also had a tow, towing a lighter, and it appeared to me the submarine was following astern of the tow.

Hewitt: Astern of the tow?

Outerbridge: Yes, sir. It may or may not have been. I think other people can testify it was standing in to Honolulu. To me it appeared to be following the Antares in and I thought, “She is going to follow the Antares in, whatever it is.” It was going fairly fast. I thought she was making about twelve knots. It seemed to be a little fast to me. I was convinced it was a submarine. I was convinced it couldn’t be anything else. It must be a submarine and it wasn’t anything that we had and we also had a message that any submarine operating in the restricted area not operating in the submarine areas and not escorted should be attacked. We had that message; so there was no doubt at all in my mind what to do. So, we went to General Quarters again and attacked. That was 0740-0640.

Hewitt: And you attacked and you reported, I believe that…

Outerbridge: Yes, sir, we reported.

Hewitt: Will you identify those exchanges of messages? Will you identify the messages on the radio log?

Outerbridge: Yes, sir. The Executive Officer was on the bridge at the time. We made the attack and we dropped depth charges in front of the submarine. The first report was, “We have dropped depth charges upon sub operating in defensive sea area.” I thought, “Well, now, maybe I had better be more definite,” because we did fire and if we said we fired, people would know it was on the surface, because saying it was a sub and dropping depth charges, they may have said it might have been a blackfish or a whale. So I said, “We have attacked fired upon and dropped depth charges upon submarine operating in defensive sea area,” so they would feel, well, he shot at something. We sent the message at 0653, the second one.

 (The radio log of the Naval Radio Station, Bishop’s Point, Oahu, containing the conversation between the Ward and Condor and the Ward’s report of attack upon a submarine, was received and marked “Exhibit 18.”)

Hewitt: What do you feel was the effect of your attack?

Outerbridge: I think we sank the submarine.

Hewitt: What do you base that on?

Outerbridge: On the gun hit, only on the gun hit.

Hewitt: There was a gun hit on it?

Outerbridge: There was a gun hit on it, and I looked these submarines over and there is no hatch between the conning tower and the tube of the submarine, where I believe it was hit, right at the waterline, the base of the conning tower.

Hewitt: And the submarine disappeared after that?

Outerbridge: Yes, sir, it disappeared.

Hewitt: That was before you made the depth charge attack?

Outerbridge: Yes, sir, we fired at the submarine before we made the depth charge attack, and as she was going under the stern, we dropped over the depth charges.

Hewitt: Your depth charges were close to her?

Outerbridge: Yes, sir.

Hewitt: Definitely?

Outerbridge: Definitely, they were there. I didn’t claim a kill.

Hewitt: Whom were those reports addressed to?

Outerbridge: I believe it was Commander Inshore Patrol. We were working for inshore patrol, but the interpretation is here.

Hewitt: You got the calls?

Outerbridge: Yes, sir, we got the calls.

Hewitt: Do you remember what they mean?

Outerbridge: No, sir.

Hewitt: Those were the only reports of that attack you made?

Outerbridge: Yes, sir, two messages on that.

Hewitt: What was your action after the completion of that attack?

Outerbridge: Well, I saw one of these large white sampans lying to out there in the defensive area.

Hewitt: Was that against regulations?

Outerbridge: That was against standing rules. They weren’t supposed to be in the defensive area, but he was in there. So, I turned around and went after him and we chased him out towards Barber’s Point. He was going pretty fast.

Hewitt: He tried to get away from you?

Outerbridge: It appeared that way to me. He could have stopped much sooner, but he appeared to be going around Barber’s Point. When we did catch up to him, he came up waving a white flag. I thought that was funny. I thought, “We will just send for the Coast Guard.” That was what we always did when we caught a sampan in the defensive area. We sent for the Coast Guard and they were very prompt. They sent a cutter out to take him in.

Hewitt: Will you identify for the record those two messages you sent about the sampan, which are on the Bishop’s Point record?

Outerbridge: “We have intercepted a sampan into Honolulu. Please have Coast Guard send cutter to relieve us of sampan.” And, “We have intercepted sampan and escorting sampan into Honolulu. Please have cutter relieve us of sampan.” We sent that. That is a little garbled, but that looks like it.

Hewitt: What was the time of it?

Outerbridge: That was 0833 and 0835.

Hewitt: Well, then, I understand that several days later you saw a midget submarine which was recovered off Bellow’s Field. Is that correct?

Outerbridge: Yes, sir, that is correct.

Hewitt: Was the appearance of the conning tower similar to the one that you saw?

Outerbridge: Yes, sir.

Hewitt: What was the condition of that submarine off Bellow’s Field? Did it have its torpedoes?

Outerbridge: Yes, sir, it was in good condition and I went inside and there was a torpedoman I believe he was a chief torpedoman working on the torpedoes, trying to get them out without exploding them, and I saw the torpedoes inside.

Hewitt: Well, I think, that is all I had planned to ask you. I am naturally interested in any information you can provide on this Pearl Harbor attack. Is there anything that you might think would be pertinent to this investigation that you can volunteer?

Outerbridge: Well, I suppose it would be a matter of opinion, which probably wouldn’t do you much good, but I was even a little surprised at the attack which followed. I mean I had no idea that the air attack was going to follow. We brought the sampan in and we got another submarine attack. We dropped four depth charges on another submarine in the area. We got depth charges that morning and at 11 o’clock we ran out. When the attack started, we were still at General Quarters. We hadn’t secured from the attack. We were still at General Quarters and we saw the planes coming in, but not until after the bombs began to fall, because the bombs were falling on Pearl Harbor, and the Exec and I were standing on the bridge. Lieutenant Commander Dowdy was the Exec and he said, “They are making a lot of noise over there this morning, Captain.” I said, “Yes, I guess they are blasting the new road from Pearl to Honolulu.” He said, “Look at those planes. They are coming straight down.” I looked at them, and he said, “Gosh, they are having an attack over there.” I said, “They certainly are,” and that was the time the attack actually began.

Hewitt: That was about 0750?

Outerbridge: 0750, yes, sir.

Hewitt: That must have been about the time, judging from this report here, that you were engaged in bringing the sampan in.

Outerbridge: Yes, sir, we were still standing in with the sampan.

Hewitt: You mentioned just then several other submarine attacks that you had the same morning.

Outerbridge: Yes, sir.

Hewitt: That was after the ones you have already discussed. What were they?

Outerbridge: They were good metallic contacts, although I was a little surprised at them at first, before things began to pop. I didn’t think we would get so many, but we did get a lot of them. We got good metallic contacts and the only thing to do was to bomb them. They gave us a good sharp echo. We bombed them until we ran out of depth charges and went in and got some more.

Hewitt: That was in the same general area?

Outerbridge: Right in that defensive area.

Hewitt: Off the entrance to the swept channel?

Outerbridge: Yes, sir. There was another thing we saw. That was a lot of explosions along the reefs. I thought that they were explosions of torpedoes fired into the reefs. I didn’t see any other submarines the whole morning. We didn’t actually see any, but we did see a lot of explosions that looked like shallow water explosions of torpedoes.

Hewitt: What would make you think they were torpedoes rather than bombs?

Outerbridge: They were right along the coast, along the reef, and I didn’t see any planes overhead. They were inside the coast in Pearl Harbor, bombing Pearl Harbor, and I didn’t think they would all miss that far. I thought they would do better than that. They did do better than that in general.

Hewitt: Do you recall approximately how many different contacts you bombed?

Outerbridge: I think we had three or four that morning, sir.

Hewitt: After the one…

Outerbridge: In the first ten days we had eighteen contacts, day and night, but we didn’t actually see any more submarines. I heard that they were there, but we didn’t actually see any more. We don’t know what the effect of the attacks were on the submarines. There was one other one, on the 2nd of January. We were with our division, making the attack, and the ship astern of us, after I got in port, told us that she saw a submarine come up under our starboard depth charge. I hadn’t, up until then, claimed any hit for it. We had a pretty good contact. It was our turn to make the run. We made the run and kept on going, and that is what the Commanding Officer of the Allen said. That was the 2nd of January. But we didn’t actually see that from the ship.

 

Destroyer USS Ward opening fire at 6:45 A.M. on a two-man Japanese submarine spotted just outside the entrance to Pearl Harbor. The four-inch shell, the first shot fired in the Pacific War, just misses the conning tower of the midget sub, one of five launched by the Japanese that morning as part of their surprise attack. At 6:54 A.M., the Ward succeeded in sinking the intruder.

 
USS Ward (DD-139), 1942. They Fired First Shot For U.S. Forces in Pacific War and Sank Japanese Submarine. This gun crew aboard USS Ward (DD 139) had the distinction of firing the first shot in their country’s reply to the Japanese attack on Pearl Harbor, December 7, 1941. With the four-inch gun with which they are shown here, they sank a Japanese midget submarine in the first hours of fighting. Note, Ward was later sunk by a Japanese kamikaze off Ormoc Bay, Leyte, on December 7, 1944, three years following her action off Pearl Harbor.

 
A Shot for Posterity, the USS Ward's number three gun and its crew—cited for firing the first shot the day of Japan's raid on Hawaii. Operating as part of the inshore patrol early in the morning of December 7, 1941, this destroyer group spotted a submarine outside Pearl Harbor, opened fire and sank her.

War Warnings: Deliberately Confused Messages

To General Short

 “Negotiations with Japanese appear to be terminated to all practical purposes with only the barest possibilities that the Japanese Government might come back and offer to continue. Japanese future action unpredictable but hostile action possible at any moment. If hostilities cannot, repeat cannot, be avoided the U. S. desires that Japan commit the first overt act. This policy should not, repeat not, be construed as restricting you to a course of action that might jeopardize your defense. Prior to Japanese hostile action you are directed to undertake such reconnaissance and other measures as you deem necessary but these measures should be carried out so as not, repeat not, to alarm the civil population or disclose intent. Report measures taken. Should hostilities occur, you will carry out task signed in Rainbow Five as far as they pertain to Japan. Limit dissemination of this highly secret information to minimum essential officers.”

To Admiral Kimmel

 “Consider this dispatch a war warning. The negotiations with Japan in an effort to stabilize conditions in the Pacific have ended. Japan is expected to make aggressive move within the next few days. An amphibious expedition against either the Philippines, Thai, or Kra Peninsula or possibly Borneo is indicated by the number and equipment of Japanese troops and the organization of their naval task forces. You will execute a defensive deployment in preparation for carrying out the tasks assigned in WPL-46 only. Guam, Samoa and Continental Districts have been directed to take appropriate measures against sabotage. A similar warning is being sent by the War Department. Inform naval district and Army authorities. British to be informed by Spenavo.”

Analysis

One message says negotiations have ended and the other says they may continue.

The Navy message emphasizes conflict and the Army message avoiding conflict.

The Navy message points attention away from Hawaii and mentions sabotage. The Army message says not to alarm the civilian population which means the lowest level of alert.

The Navy plan implements War Plan WPL-46 only, which forced Kimmel to use the few long-range patrol planes he had to scout the Marshall Islands to the southwest.

The Army message forbids the first overt act. Those are the words of FDR. They are also words that denote knowledge of the coming attack, because Hawaii wasn’t about to attack Japan.

The sabotage fig leaf was to distract the Hawaiian commanders from understanding the meaning of ‘overt act.’ But no one could allow sabotage, so it cannot have referred to that. What ‘overt act’ do you think FDR was referring to? Since attacking Japan and sabotage were impossible, that leaves only one possibility—Japan attacking Hawaii. The words “overt act” prove that FDR knew Japan would attack Hawaii.

The President’s own commission on Pearl Harbor declared that the Hawaiian commanders needed to “consult and confer with the other respecting the meaning and intent of the warnings” because they were so confusing. These messages were held by the Roosevelt administration as sufficient warning to Hawaii both before and after 7 December. No other defense was raised for denying IQ and not sending warnings to Hawaii. The Navy Court and Army Board found them totally inadequate, as indeed they are.

However, by 1940 there was a shortage of modern equipment and trained personnel, and not until February 1941 did troop reinforcements and up-to-date equipment begin to arrive in Hawaii. The United States was not prepared for war and the men and equipment did not meet the necessary requirements.

Tatsuta Maru, flagship of the NYK [Nippon Yusen Kaisha] Line, view taken circa 1940, with neutrality markings prominently displayed on the sides of her hull, forward. The Tatsuta Maru (16,975 grt, 584 ft. long) commenced her maiden voyage between Yokohama and San Francisco in April 1930. The transliteration of her name was changed to Tatuta Maru in 1938. In December 1941 Tatsuta Maru was part of an elaborate Japanese deception plan to mask the unannounced attack on the U.S. Pacific Fleet in Pearl Harbor.

 
Tatsuta Maru, marked with symbols of safe passage while working as a repatriation ship as seen through the periscope of the U.S. Navy submarine USS Kingfish (SS-234) in October 1942. Subsequently, with the start of the Pacific War, the Tatsuta Maru was requisitioned for use as a troopship for the Imperial Japanese Navy. She ended her days in 1943 when sunk by a U.S. submarine off Mikurajima, 120 miles south of Tokyo Bay. Her sistership the Asama Maru was near-identical, whereas a half-sister, the Chichibu Maru, was slightly larger with only one funnel. In 1942, the Tatsuta Maru and two other NYK vessels - Asama Maru and Kamakura Maru - provided transport for exchange of U.S., British, and Japanese diplomats.

 
Tatsuta Maru marked with symbols of safe passage while working as a repatriation ship. She sailed from Yokohama on 2 December bound for San Francisco with the task of exchanging American evacuees from East Asia for Japanese nationals in the United States. She was scheduled to reach the U.S. on 14 December and despite rumors of war the American press wrongly concluded that meant nothing was likely to happen for some time. The master of the ship had sealed orders to turn around at midnight on 7 December and return to Japan while maintaining radio silence.
