At six fifty-three in the morning on Sunday, December seventh, nineteen forty-one, a radio operator at Bishop's Point on Oahu copied a voice message from a destroyer patrolling off the mouth of Pearl Harbor. It read, word for word, "We have attacked fired upon and dropped depth charges upon submarine operating in defensive sea area." The ship that sent it was U S S Ward. She was twenty-three years old. Her keel had been laid and her hull launched in seventeen and a half days, a rush job from the last war. Most of her crew were naval reservists from Saint Paul, Minnesota. Her captain had been in command for two days.

The message went up the chain. The chief of staff of the Fourteenth Naval District, Captain John Earle, read it and decided, in his own later words, that the Ward was making another mistake. He had seen ten or fifteen submarine reports off that harbor in the months before. None had been real. He asked for the dispatch to be verified, called his admiral, and the two men agreed to wait for further developments.

Sixty-four minutes after the Ward's message, Japanese bombs were falling on Ford Island, in the middle of Pearl Harbor.

That much is in the record. What the record could not settle, for the next sixty years, was whether the Ward had hit anything at all. No wreck was found, and the ship's own report contradicted itself on the range. So this is a case, and it runs on evidence. Did a nineteen eighteen destroyer, built in a hurry, crewed by part-time sailors and commanded by a man on his first patrol, really fire the first American shot of the Pacific War and sink an enemy submarine more than an hour before the attack began? Or was the Ward, as Captain Earle believed, just one more nervous ship shooting at shadows?

Start with the suspect herself, because nothing about the Ward suggested she would be the ship to start a war.

She was one of the flush-deckers, the four-funneled destroyers the United States ordered in a panic once the scale of the German U-boat campaign became clear in nineteen seventeen. Two hundred sixty-seven ships of the Wickes and Clemson classes were built, and work on cruisers and battleships was delayed to keep the destroyer slipways moving. The Ward was laid down at the Mare Island Navy Yard in California on May fifteenth, nineteen eighteen, and launched on June first. Seventeen and a half days. She was commissioned on July twenty-fourth.

What came out of that slipway was three hundred fourteen feet long, displaced about twelve hundred tons, and could make thirty-five knots. She carried four four-inch fifty-caliber guns, twelve torpedo tubes in four triple mounts, and depth charge racks at the stern. By the standards of nineteen forty-one, that was a museum exhibit. The navies of the world had moved on to destroyers twice her displacement, with enclosed dual-purpose gun mounts and director fire control. The Ward had neither.

And she had spent most of her life asleep. She was decommissioned in July nineteen twenty-one and laid up for almost twenty years. When the war in Europe began, the Navy pulled the old four-stackers out of reserve, and the Ward was recommissioned on January fifteenth, nineteen forty-one, and sent to the newly formed Pacific Fleet at Pearl Harbor.

The crew that brought her back to life was not a crew of career destroyermen. Four officers and eighty enlisted men came from the Minnesota Naval Militia, most of them from Saint Paul. They were reservists called to active duty, part-time sailors from a state in the middle of the continent. And on December fifth, nineteen forty-one, the Ward received a new commanding officer. Lieutenant Commander William Outerbridge was thirty-five, born in Hong Kong, raised in Ohio, Naval Academy class of nineteen twenty-seven. He had been executive officer of the destroyer Cummings. He had never commanded a ship. His first patrol as captain began the next day.

So that is the suspect. An old hull, a reserve crew, a brand-new captain. Every factor the conventional view of naval power counts as weakness. Which raises the first real question of the case. If the Ward did sink a submarine that morning, she was not the first ship to see one. Who saw it first, and why did nobody tell anyone?

The first witness was a minesweeper. At three forty-two in the morning, the coastal minesweeper U S S Condor was working a magnetic sweep in the approach channel when her crew sighted a periscope near the entrance buoys. The object was about a hundred feet away and on a collision course. It turned sharply to port. The Condor turned to starboard. Between three fifty and three fifty-eight, the Condor flashed a signal by blinker light to the Ward, which was the duty destroyer on the inshore patrol. The message read, "Sighted submerged submarine on westerly course speed nine knots."

Outerbridge went to general quarters and took the Ward to the Condor's position. He slowed to ten knots and began a sonar search to the westward. He found nothing. After more than an hour, he called the Condor by radio and asked for the submarine's course and distance. The answer came back at five twenty. The course was about zero two zero magnetic, about a thousand yards from the entrance, and apparently heading for the entrance.

Outerbridge understood at once that he had been searching in the wrong direction. The contact had not been heading west. It had been heading into Pearl Harbor.

And here the record shows how the warning died. The Condor did not report the sighting to anyone except the Ward. Her captain judged that the identification was not positive enough. Outerbridge, as senior officer present afloat, did not report it either. He later told the Hewitt Inquiry, the Navy's nineteen forty-five investigation into the attack, that he reasoned this way. If the Condor's captain did not report it, he must not think it was a submarine. It may have been anything, Outerbridge said. It may have been a buoy. The radio station at Bishop's Point overheard and logged the whole exchange, but because it was a conversation between two ships and nobody asked for it to be relayed, the station passed it to no one.

There was one more fact in that file, and it is the most uncomfortable. At the harbor entrance, a gate vessel opened and closed the anti-submarine net. Standing instructions said the net was to stay closed from sunset to sunrise. At four fifty-eight that morning, the gate was opened to let the minesweepers Crossbill and Condor in. It was not closed again until eight forty-six.

For almost four hours, the door to the most important American naval base in the Pacific stood open, while a submarine sighting sat unreported in a radio log. Then, at six thirty, a second witness saw the same kind of object, and this time it was broad daylight.

The U S S Antares was coming in from Canton and Palmyra islands with a five-hundred-ton steel barge in tow. She exchanged calls with the Ward at about six oh five. At six thirty, her lookouts sighted a suspicious object, apparently a small submarine, about fifteen hundred yards on her starboard quarter. The Antares signaled the Ward to investigate. A few minutes later, a Navy Catalina flying boat, patrol plane fourteen P one flown by Ensign William Tanner of Patrol Squadron Fourteen, circled the object and dropped two smoke markers on it.

What all three of them were looking at was one of the most specialized weapons the Imperial Japanese Navy had built, and its design explains every move it made that morning.

It was a Type A midget submarine of the Ko-hyoteki class. The hull was about seventy-eight feet long and just under six feet across, with a displacement of about forty-six tons submerged. There was no diesel engine at all. A single six-hundred-horsepower electric motor drove two counter-rotating propellers on one shaft, fed by one hundred ninety-two trays of battery cells packed into the hull. That arrangement gave the boat a burst speed of nineteen knots underwater, faster than most full-size submarines of the day, but only for about eighteen nautical miles. At six knots, it could go about eighty. When the batteries were flat, the boat was finished. It carried two eighteen-inch torpedoes in muzzle-loaded tubes, one above the other in the bow, and a crew of two. A junior officer conned the boat while a petty officer worked the valves and shifted ballast to hold trim.

Five of these boats had been carried to Hawaii piggyback on the decks of five large fleet submarines. The plan was to slip them into the harbor ahead of the air raid, and use their torpedoes against the battle line while the bombing was under way. The boat the Ward was about to meet had been launched by the submarine I-twenty at two fifty-seven that morning, five point three miles from the harbor entrance. Her crew were Ensign Akira Hiroo and Petty Officer Yoshio Katayama.

Now the behavior makes sense. A boat with eighteen miles of fast running in its batteries cannot afford to fight its way through a net. It has to wait for a gate to open, and follow something larger through it. The Antares, slow, towing a barge, heading for the entrance, was exactly that. At six thirty-seven, the submarine was tucked in behind her.

Which is where the Ward came in, and where her own report starts to disagree with itself.

At six thirty-seven, the officer of the deck, Lieutenant junior grade Oscar Goepner, called down to the emergency cabin. Outerbridge's action report, written on December thirteenth, records the words exactly. "Captain, come on the bridge." Outerbridge later testified that the helmsman was the first man to sight the object. At first it looked like a buoy. Then the watch decided it was a conning tower, unlike anything in the American Navy. Outerbridge reached the bridge, looked, and was convinced. He had standing orders that any submarine operating submerged in the restricted area, outside the submarine areas and without escort, was to be attacked. He told the inquiry there was no doubt at all in his mind what to do.

At six forty, the Ward began her run. The engine room took her from five knots to twenty-five. The report describes the target as a cylindrical tube about eighty feet long with a small oval conning tower and no deck, painted dark green and covered with moss, as if it had been at sea for a long time. It was making eight to ten knots, and through five minutes of the Ward's approach, it never appeared to notice the destroyer bearing down on it. Its crew were watching the Antares.

At six forty-five, the Ward opened fire. Number one gun, on the forecastle, fired a single round. The shell passed directly over the conning tower and missed. Number three gun, manned by the Minnesota reservists, fired a single round. That shell struck the submarine at the waterline, at the junction of the hull and the conning tower. The report calls it a square positive hit. The submarine heeled over to starboard, slowed, and began to sink. As it went under the stern, the Ward rolled four depth charges set for one hundred feet, which was about the maximum depth the midget was built to reach. Overhead, the crew of the Antares saw Tanner's Catalina appear to drop bombs or depth charges on the same spot. A large amount of oil came to the surface. The Ward's sonar could not find the contact again. The report records the depth there as twelve hundred feet.

Two shots. One hit. Four depth charges. The whole fight lasted a minute or two.

Now look closely at that report, because this is where the doubters found their opening. In one paragraph, Outerbridge wrote that number three gun fired at a range of five hundred sixty yards or less. In the next section of the same document, he wrote that at the first shot the range was not more than one hundred yards, and at the second shot fifty yards or less. Those figures cannot all be right. Fifty yards is point-blank, closer than the length of the Ward herself. Five hundred sixty yards is a third of a mile. A skeptic reading the file could argue that if the captain could not say how far away the target was, he could not be certain what it was, or whether his shell had struck it at all.

And there was no wreckage, and no bodies. The only evidence was what a few dozen men on a destroyer said they had seen.

Outerbridge understood that problem from the first minute, and his radio messages show it. At six fifty-one, he sent his first report to the commandant of the Fourteenth Naval District. "We have dropped depth charges upon subs operating in defensive sea area." Then he reconsidered. He explained his reasoning to the Hewitt Inquiry. If he reported only depth charges, the staff ashore could decide he had attacked a blackfish or a whale. If he reported that he had fired guns, they would know the target had been on the surface, where his men could see it. So at six fifty-three, he sent the second message, the one that opens this story. Attacked. Fired upon. Depth charges. Submarine.

He had written a message that could not be misread. So why did it still fail?

The answer is in the timeline the Hewitt Inquiry pieced together afterward, minute by minute. The Bishop's Point station received the message and relayed it to the inshore patrol. The district communications watch officer delivered it to the duty officer, Lieutenant Commander Harold Kaminski. It had to be decoded and re-sent, on a Sunday morning, by a skeleton watch. Kaminski reached Captain Earle at seven twelve. At Earle's direction, he notified the duty officer of the Commander in Chief, Pacific Fleet, at seven fifteen.

Earle called Admiral Claude Bloch, the district commandant. Their reaction, as the inquiry recorded it, was that the Ward had probably been mistaken. If she was not mistaken, she and the ready-duty destroyer Monaghan, which was ordered out to join her, could handle the situation. And since the information had already gone up to Admiral Husband Kimmel's headquarters, the commander in chief could take any further action he wanted. Earle testified that the report did not suggest an air attack to him, and the two men never discussed whether a submarine off the harbor might mean something larger was coming.

A second report was running up a different chain at the same time. Ensign Tanner's Catalina had attacked the submarine as well. Admiral Patrick Bellinger, who commanded the patrol wings, later read his headquarters log into the record. Seven hundred, patrol plane fourteen P one attacks an enemy submarine one mile off the entrance. Seven fifteen, message coded and sent to base. Seven thirty-five, message decoded. Seven forty, relayed by telephone to the staff duty officer of the commander in chief. Seven fifty-seven, first bomb dropped near the hangar of Patrol Squadron Twenty-two. Seven fifty-eight, the broadcast to all ships. "Air raid Pearl Harbor. This is no drill."

Two independent American units had attacked the same submarine and reported it. Both reports reached the fleet's headquarters. Neither one changed anything in time.

Out at sea, the Ward had no idea. After the attack, Outerbridge chased a sampan out of the defensive area toward Barbers Point and called for the Coast Guard to take it in. At about seven fifty, he was standing on the bridge with his executive officer, Lieutenant Commander Dowdy. Dowdy said they were making a lot of noise over there this morning. Outerbridge answered that he guessed they were blasting the new road from Pearl to Honolulu. Then Dowdy said, "Look at those planes. They are coming straight down."

The Ward stayed at general quarters all morning. She dropped depth charges on contact after contact until she ran out around eleven o'clock and had to go in for more.

So, verdict pending. The Ward had reported her attack clearly and fast. The system had heard it and filed it as another false alarm. But that left the original question standing. Had she been right? For decades, nobody could say for certain. Of the five midget submarines, one ran aground on the windward side of Oahu, and its commander, Ensign Kazuo Sakamaki, became the first Japanese prisoner of the war. One was sunk inside the harbor by the destroyer Monaghan at eight forty-three. One was found off the harbor entrance in nineteen sixty. Nine of the ten Japanese crewmen died. But the boat the Ward said she sank, in twelve hundred feet of water just off the channel, stayed missing. Outerbridge himself was careful. Asked by the inquiry what he based his claim on, he answered, "On the gun hit, only on the gun hit." He was awarded the Navy Cross. Whether he had earned it was something the evidence could not yet prove.

The proof finally came from the bottom of the sea.

Researchers at the University of Hawaii's Hawaii Undersea Research Laboratory had been looking for the Ward's submarine for more than a decade, using the lab's two small deep-diving submersibles, Pisces Four and Pisces Five. On August twenty-eighth, two thousand two, around noon, Terry Kerby and his team found it. The boat lay three to four miles outside the harbor entrance, at a depth of about twelve hundred feet, sitting upright and intact on the sea floor.

Every detail matched the report Outerbridge had written sixty-one years earlier. Both torpedoes were still in their tubes. The submarine had never fired. The depth charges had done no visible structural damage to the hull. And at the base of the conning tower, on the starboard side, at the junction of the tower and the hull, there was a single shell hole about four inches across. A four-inch hole, from a four-inch gun. The midget had sunk because seawater poured in through that hole, and the hole sat exactly where number three gun's crew had said their shell struck.

The report had placed the sinking in twelve hundred feet of water, and the wreck lay at about that depth. The contradiction over the range no longer mattered. Whatever the distance, the shell had gone exactly where the gun crew said it went.

That is the verdict. The Ward was right. Captain Earle was wrong. The first shot fired by the United States in the Pacific War came from a four-inch gun on a destroyer built in seventeen and a half days, aimed by reservists from Minnesota, under a captain who had held command for two days. It hit. It sank a submarine carrying two torpedoes toward the most important harbor in the Pacific, more than an hour before the first bomb fell. The weakness in the system that morning had nothing to do with the ship's age. The old destroyer saw, decided, fired, and reported. The organization ashore, with ten or fifteen false alarms behind it, could not believe her.

But the case has one more entry, and it is the strangest thing in the Ward's file.

In nineteen forty-two, the Navy sent the Ward to the West Coast for conversion. She was rebuilt to carry troops and landing boats, and in February nineteen forty-three she was redesignated a high-speed transport, A P D sixteen. Number three gun, the one that fired the shot, was removed during the work. The Ward went to the Solomon Islands, helped fight off a heavy air attack off Tulagi on April seventh, nineteen forty-three, and then carried troops and escorted convoys through landing after landing in the Southwest Pacific, from Cape Gloucester to Biak and Morotai. On October seventeenth, nineteen forty-four, she put troops ashore on Dinagat Island in the opening hours of the Leyte invasion.

In early December, she carried Army troops to the landings at Ormoc Bay, on the western side of Leyte. On the morning of December seventh, nineteen forty-four, three years to the day after she fired at the submarine off Pearl Harbor, the Ward was patrolling off the invasion area when Japanese kamikaze aircraft came in. A twin-engine bomber struck her amidships. She lost power and came to a dead stop, and fires spread through the ship that her crew could not bring under control. The order came to abandon ship, and her crew were taken off by other ships.

Then someone had to sink her, so that the burning hulk would not be left adrift. The order went to the destroyer U S S O'Brien. Her commanding officer was Commander William Outerbridge. He had taken command of her in June nineteen forty-four and fought with her off Normandy before she came out to the Pacific. On the anniversary of the morning he had fired the Ward's first shot, he gave the order to open fire on the Ward herself.

She sank in Ormoc Bay. In December two thousand seventeen, the research vessel Petrel found her wreck at a depth of more than six hundred feet.

Outerbridge retired in nineteen fifty-seven as a rear admiral and taught science to schoolchildren. He died in nineteen eighty-six, sixteen years before the submersibles found the hole in the conning tower. He never saw his claim proven. Number three gun went home to the men who had fired it. In nineteen fifty-eight, Minnesota's centennial year, it was mounted on the grounds of the state capitol in Saint Paul. The last surviving member of its crew from that morning, Alan Sanford, died in January two thousand fifteen at the age of ninety-one. In December two thousand twenty-five, the gun moved indoors, to the new home of the Minnesota Military and Veterans Museum at Camp Ripley.

The old destroyer from Mare Island lies in Ormoc Bay, sunk by the captain who took her into her first fight. The submarine she sank lies upright off Pearl Harbor, torpedoes still loaded, a four-inch hole at the base of its conning tower. Between those two wrecks is the whole of America's Pacific war, and the Ward was there at both ends of it.
