Schauer stood stunned for a moment, his mind unable to comprehend what his eyes and ears had just absorbed. It took the sight of a second orange flash to jolt him into action.

“Get down!” he shouted at the two men in the cabin as he spun the ship's wheel hard to port. The laden trawler was slow to respond, but it was enough to avoid the second shell from the I-403's 5.5-inch deck gun, which screamed into the water just astern of the boat. This time, the force of the explosion lifted the entire trawler out of the water and slammed it back down again hard, shearing the rudder off in the upheaval.

Wiping blood out of his eyes from a gash to the temple, Schauer groped for the radio microphone.

“Doug, there's a Jap sub. It's blasting the hell out of us. No joke. Keep to the north, and get help.”

He was still talking when the third shell found its mark, piercing the forward hold of the fishing boat before detonating. A furious explosion of splinters, glass, and mangled halibut blasted into the cabin, throwing the three men viciously to the back wall. Struggling to his feet, Schauer peered out a gaping hole in the front of the cabin and saw the entire bow of the trawler disintegrate into the sea before him. Instinctively grabbing the wheel for support, he looked on in disbelief as the remains of the boat began to sink rapidly beneath his feet.

Peering through binoculars, Ogawa watched with grim satisfaction as the trawler slipped beneath the waves amid a scattering of flotsam. Rescuing survivors was out of the question, so he wasted no time in looking for bodies in the water.

“Motoshita, have there been any additional sound recordings?” he asked his exec.

“Negative, sir. The sound operator reported a possible secondary target before we initiated firing but the reading faded. It was either background noise, or a small vessel at best.”

“Have him keep sweeping. With this visibility, we will hear a vessel well before seeing her. And have the chief aircraft mechanic report to me. We've got to get those planes launched.”

As Motoshita scurried off, Ogawa stared toward the hidden coastline of Washington. Perhaps we'll get lucky, he thought. The trawler was likely a lone fishing boat and wouldn't have a radio. The guns could have been heard ashore, but, at this distance, would sound like an innocuous muffle. The charts showed few inhabitants residing along that stretch of coast as well. Perhaps-just perhaps-they could still pull off the mission undetected.

The hairs on the back of Radioman First Class Gene Hampton's neck stood up like a grove of ponderosa pine. The voice ringing through his earphones had an air of urgency and authenticity that could not help but be believed. After confirming the message twice, Hampton popped out of his chair like a jack-in-the-box and bounded to the center of the bridge.

“Captain, I just picked up a civilian Mayday message,” he blurted excitedly. “A fisherman says there's a Jap sub offshore shelling his brother's boat.”

“Did he sound coherent?” replied the ship's bearded, heavyset commander in a skeptical tone.

“Yes, sir. Said he didn't see the sub because of the fog but got a radio call from his brother on another fishing boat. He heard a couple of shots fired from a big gun, then lost contact with his brother. I received a call from another boat confirming the sound of gunfire.”

“Did they provide a fix on the location?”

“Yes, sir. Nine miles southwest of Cape Flattery.”

“Very well. Contact the Madison and tell her we are headed out of the strait to investigate a reported enemy contact, then provide a location fix to Navigation. Mr. Baker,” he continued, turning to a tall lieutenant standing at his side, “let's go to General Quarters.”

As an alarm bell rang throughout the ship, the crew of the USS Theodore Knight scrambled to their battle stations, adorning helmets and kapoks as they ran. It wasn't the first time the Farragut-class destroyer had seen action. Launched in 1931 at the Bath Iron Works shipyard in Maine, the Theodore Knight had an active service duty garnering North Atlantic convoy duty in the early stages of the war. After dodging several U-boat attacks while escorting the merchant fleets, the 341-foot-long destroyer was sent back for patrol and escort duty off the West Coast, sailing the waters from San Diego to Alaska.

Trailing three miles behind, in the Strait of Juan de Fuca, was the Liberty Ship Madison, bound for San Francisco with a cargo of lumber and tinned salmon. Leaving the assigned cargo ship in its wake, the Theodore Knight broached the mouth of the Pacific as its captain, Lieutenant Commander Roy Baxter, ordered flank speed. The ship's twin diesel turbines churned the sleek gray ship through the water like a hound chasing a rabbit. The crew, accustomed to quiet, routine patrols, was at an unusually heightened sense of readiness at the prospect of facing the enemy.

Even Baxter felt his heart beat a little faster. A twenty-year Navy man, he had seen action in the Atlantic but had grown bored with his recent assignment on the home shores. He relished the thought of tasting battle again, though remained skeptical about the radio report. Japanese subs had not been seen off the coast for over a year, he knew, and the Imperial Navy was now clearly on the defensive. “Radar?” he demanded loudly.

“Sir, I have three small vessels approaching the channel, two from the north and one from the west,” replied the radarman without taking his eyes off his monitor. “I have another indefinite target that appears to be stationary lying to the southwest.”

“Take us to the southern mark,” Baxter barked. “And have the forward batteries stand by for action.” The commander had to suppress a grin of excitement as he issued the orders. Maybe we'll earn our pay today, he thought while strapping on his helmet.

Unlike their American counterparts, most Japanese submarines in World War II were not equipped with radar. The early-warning technology was only first deployed on Imperial submarines in mid-1944, and then installed only on selected vessels. Most Japanese submarines instead relied upon sound-detection equipment to reveal a distant enemy. Although more limited in range than radar, sound detection could be utilized underwater, and aided many a sub in avoiding a fatal rendezvous with depth charges.

Absent a radar unit, it was the I-403^ sound operator who first became aware of the destroyer bearing down on them.

“Vessel approaching ahead ... sound intensity one,” he reported at the first registering on his equipment.

On deck, both of the aircraft had been moved out of their hangars, where the wings and pontoons were affixed, while repairs continued. It was the situation Ogawa feared most. With both planes assembled but neither ready for flight, they would have to be sacrificed should the submarine have to make an emergency dive.

“Deck gun at the ready,” he ordered, hoping the unwelcome intruder was yet another fishing boat.

“Sound intensity two and increasing,” the sound operator relayed calmly. “It's a ship,” he added, to no one's surprise.

“Secure all aircraft and clear the aviation deck,” Ogawa ordered an ensign, who sprinted down the large deck shouting at the mechanics and pilots as he ran. Tying down the two airplanes, the aviation crew quickly grabbed their work tools and scurried to the hangar. The watertight doors of the hangar were closed and sealed; then the men dropped down another hatch into the secure body of the submarine.

“Sound intensity three, off our bow. May be a destroyer,” the operator reported, correctly identifying the churning sound of the tin can's twin propellers.

As if on cue, the gray ship materialized out of the fog a half mile away, the apparition of a steel wraith charging across the moor. White foam burst off the bow in angry torrents while wisps of dark smoke billowed from the funnel. The lean ship drove straight at the sub, an attacking lancer not to be denied.
