3 Battering Down the Gate: The Western Hinge
Toward the end of 1942, as the Japanese defense of Guadalcanal was crumbling, American forces began to inch forward elsewhere in the Pacific, most notably on the island of New Guinea, almost 600 miles to the west of Guadalcanal.
New Guinea is the second largest island in the world (only Greenland is larger). Dropped over the United States, the island would reach from New York City to Houston, Texas; it is big enough to cover all of New England, plus New York, Pennsylvania, Maryland, West Virginia, Ohio, Kentucky, and all of Tennessee, except for Memphis and its suburbs. Even today, vast inland areas are unexplored and possibly some tribes in the mountains have never even heard about the white man—or about the Japanese either, for that matter. The island is shaped like a turkey, with its head and wattles pointed east.

Early in the war, right after the fall of the Philippines and of the East Indies, the Japanese had landed on the turkey’s back. The Australians held the turkey’s belly. The Japanese had tried to cross the grim Owen Stanley Mountains, to get at the turkey’s underside, but tough Australian troops had slugged it out with them and pushed them back. The fight in the mountains was so miserable for both sides that everybody had tacitly agreed that the battle for New Guinea would be decided along the beaches.
Splitting the very tip of the turkey’s tail is Milne Bay, a magnificent anchorage. Whoever held Milne Bay could prevent the other side from spreading farther along the coast. Australians and Americans, under the command of General MacArthur, moved first, seized Milne Bay in June of 1942, and successfully fought off a Japanese landing force.
A curious example of the misery the homefolks can deal out to front-line fighters is the mix-up caused by the code name for Milne Bay. For some obscure reason, the Gili Gili base, at Milne Bay, was called “Fall River.” Naturally, according to the inexorable workings of Murphy’s Law (if anything can go wrong, it will) many of the supplies for Milne Bay were delivered to bewildered supply officers at Fall River, Massachusetts.
Despite this foul-up, by the end of October, 1942, Milne Bay was safely in the hands of the Allies and ready to support an advance along the bird’s back. All movement had to be by sea, for there were no roads through New Guinea’s jungles, and the waters around the turkey’s tail were the most poorly charted in the world. Navigators of deep-draft ships were horrified to have to sail through reef- and rock-filled waters, depending on charts with disquieting notes like “Reef possibly seen here by Entrecasteaux in 1791.” No naval commander in his right mind would commit deep-draft ships to such uncharted and dangerous waters for nighttime duty. Which means that the times and the coastal waters of eastern New Guinea were made for PT boats, or vice versa.
On December 17, 1942, less than a week after the PTs of Tulagi had fought the last big battle with the incoming Tokyo Express, the PT tender Hilo towed two torpedo boats into Milne Bay and set up for business. Other PTs followed. For seven more months motor torpedo boats were to be the entire surface striking force of the U. S. Navy in the Solomon Sea around the tail of the New Guinea turkey.
By the time the Hilo had arrived at Milne Bay, the fight for the turkey’s back had moved 200 miles up the coast to a trio of villages called Buna, Gona, and Sanananda. Two hundred miles is too long a haul for PT boats, so the Hilo stayed at Milne Bay as a kind of rear base, the main striking force of PTs moving closer to the fighting. They set up camp at Tufi, in the jungles around Oro Bay, almost within sight of the Buna battlefield, and began the nightly coastal patrols that were to stretch on for almost two weary years before all of New Guinea was back in Allied hands.
First blood was drawn on Christmas Eve. Ensign Robert F. Lynch celebrated the holiday by taking out the PT 122 for a routine patrol, looking for small Japanese coasters or submarines running supplies and reinforcements into Buna. The night was dark and rainy, and the PT chugged along without much hope of finding any action. PTs had no radar in those days, and a visual lookout was not very effective in a New Guinea downpour.
Even in New Guinea, however, the rain cannot go on forever. When the rain clouds parted, a bright moon lit up the sea and a lookout snapped to attention.
“Submarine,” he hissed. “Dead ahead, a submarine.”
Hove to on the surface was a Japanese I-boat, probably waiting for Japanese small craft to come from the beach for supplies, or else recharging its batteries, or probably both. Ensign Lynch began his silent stalk and closed to 1,000 yards without alarming the submarine’s crew. He fired two torpedoes and kept on closing the range to 500 yards, where he fired two more. The submarine went up in a geyser of water, scrap iron, and flame.
Ensign Lynch thought he saw a dim shape beyond his victim and was alert when another surfaced I-boat shot four torpedoes at him. He slipped between the torpedo tracks, but could do nothing about retaliating, because he had emptied his tubes. He had to let the second I-boat go. Postwar assessment gives Ensign Lynch a definite kill on this submarine.
The same Christmas Eve, two other PTs from the Oro Bay base sank two barges full of troops.
Ensign Lynch’s torpedoing of the submarine—the first combat victory of the PT fleet in New Guinea waters—was a spectacular triumph, but the sinking of two barges was much more typical of the action to come.
The terrible attrition of ships in the Guadalcanal fight had left the Japanese short of sea transport. Besides, Allied airmen made the sea approaches to New Guinea a dangerous place for surface craft in daylight. Nevertheless, the Japanese had to find some way to supply their New Guinea beachheads by sea or give them up, so they began a crash program of barge construction.
The barges were of many types, but the most formidable was the daihatsu, a steel or wooden barge, diesel powered, armored, heavily armed with machine guns or even with automatic light cannon. They could not be torpedoed, because their draft was so shallow that a torpedo would pass harmlessly under their hulls. They could soak up enormous amounts of machine-gun fire and could strike back with their own automatic weapons and the weapons of soldier passengers. A single daihatsu could be a dangerous target for a PT. A fleet of daihatsus, giving each other mutual fire support, could well be too much to handle even for a brace of coordinated PTs.
The naval war around New Guinea became a nightly brawl between daihatsu and PT, and the torpedo function of the PT shriveled. Eventually many of the boats abandoned their torpedo tubes entirely and placed them with 37-mm. and 40-mm. cannon and extra 50-caliber machine guns, fine weapons for punching through a daihatsu’s armor. The PT in New Guinea gradually changed its main armament from the torpedo—a sledge-hammer type of weapon for battering heavy warships—to the multiple autocannon—a buzz-saw type of weapon for slicing up small craft.
At the Buna-Gona-Sanananda battlefield, the Japanese were dying of starvation. It was the story of Guadalcanal again—with supply from the sea cut off by aggressive American patrols, the emperor’s infantry—no matter how desperately brave—could not stand up to a long campaign.
The night between January 17th and 18th, the Roaring Twenty (PT 120) caught three barges trying to slip out of Sanananda. The PT recklessly took on all three in a machine-gun duel, sank two of them, and set the third afire. PT sailors were the first to know that the end had come for the Japanese ashore, because the barges were loaded with Japanese officers trying to slip away from their doomed men. Next day Sanananda fell to the Australians.
When both the base at Sanananda, on the turkey’s tail, and Guadalcanal fell to the Allies in the first months of 1943, the Japanese tried to slam an impenetrable gate across the path of the Allied advance. The eastern hinge of the gate was to be the mighty naval base and airfield complex at Rabaul, on the island of New Britain. The western hinge was planned for the place where the turkey’s tail joins the turkey’s back, an indentation of the New Guinea coastline called Huon Gulf.
To build up the western hinge of the gate, the Japanese landed at the ports of Lae, Salamaua, and Finschhafen, on the Huon Gulf. The Japanese wanted Huon Gulf so badly that they even dared send a fleet of surface transports to ferry 6,900 reinforcements across the Bismarck Sea to New Guinea. The convoy run was daring, because it would be within reach of land-based Allied bombers almost the whole way.
Escorting the eight transports were eight destroyers, veterans of the Tokyo Express. Tanaka, however, was no longer with them. He had been relieved of his command for telling the high navy brass in Tokyo some unpleasant truths. He spent the rest of the war on the beach as a penalty for speaking up about mistakes made at Guadalcanal.
The Japanese convoy sailed from Rabaul, at the eastern hinge of the gate, on March 1st, under cover of a terrible storm which the ships’ captains hoped would ground Allied bombers. On March 3rd the storm lifted unexpectedly. The seasick soldiers felt slightly less miserable.
In Japan March 3rd is Doll’s Day, a sentimental family holiday when little Japanese girls dress up their dolls and parade them about the streets under the fond eyes of admiring fathers. Many of the soldiers were depressed at being on such a martial mission on Doll’s Day, so their officers passed out candy as a little touch of holiday. The officers did not tell the soldiers that the lifting of the storm had been a disaster, that an Allied snooper had already spotted the convoy, and that Allied bombers were almost surely on the way.
Worse was on the way than ordinary bombers.
Back in Australia, the American bomber force had been working on a new dirty trick, and bomber pilots were eager to try it on the transports crowded with candy-munching soldiers.
Mechanics had torn out all the bombardier equipment from the nose of B 25 attack bombers and had mounted eight 50-caliber machine guns. Under each B 25 they had slung two 500-pound bombs armed with five-second delay fuses. The idea was to make a low-level bombing run, so as to skip the bombs across the water like flat stones. The delayed-action fuses were to keep the bombs from detonating until they had slammed into the ships’ sides. When the snooper reported the convoy, it sounded to Allied bomber pilots like the perfect target for testing the new weapon.
While fighters and high-level bombers kept the Japanese convoy occupied, the converted B 25s came at the Japanese so low that the blast of their propellers churned the sea. The Japanese skippers thought they were torpedo bombers—which they were, in a sense—and turned into the attack, to present the narrowest possible target, a wise maneuver ordinarily, but this also made the ships the best possible targets for the long, thin pattern of the machine-gun ripsaws mounted in the bombers’ noses. The ships were ripped from stem to gudgeon by the strafing runs. Then, when the pilots were sure the antiaircraft gun crews had been sawed to shreds, the low-flying B 25s charged at the ships broadside and released the skip bombs, which caved in hull plates at the waterlines and let in fatal doses of sea water. It was almost impossible to miss with a skip bomb. By nightfall the Bismarck Sea was dotted with rafts, lifeboats, and swimmers clinging to the debris of sunken ships. Only darkness stopped the slaughter from the air.
After that sunset, however, the slaughter from the sea became more grisly than ever. Eight PTs from New Guinea, under Lieut. Commander Barry K. Atkins, fought their way to the battle zone through the heavy seas in the wake of the storm which had so treacherously deserted the Japanese convoy.
Just before midnight they spotted the burning transport Oigawa Maru. PT 143 and PT 150 each fired a torpedo and blew the transport out of the water. The PT sailors searched all night but could find no other targets—largely because almost all of them were already on the floor of the Bismarck Sea.
When the sun came up they had targets enough, but of a most distasteful kind. The sea was swarming with Japanese survivors, and it was the unhappy duty of the PTs to try to kill them to the last man, so that they could not get ashore on nearby New Guinea.
On March 5th the same two PTs that had sunk the Oigawa Maru jumped a Japanese submarine picking up survivors from three boats. The PTs charged, firing torpedoes, but they missed the crash-diving submarine. Then they were presented with the hideous problem of what to do with the 100 helpless soldiers who watched fearfully from the three boats. The Japanese would not surrender, and they could not be allowed to escape.
The two PTs turned on the machine guns and set about the grim butchery of the unhappy Japanese. When the execution was over, they sank the three blood-drenched boats with a shallow pattern of depth charges.
Scout planes conned other PTs to lifeboats and rafts crammed with Japanese. More than 3,000 soldiers died, but so thick were the survivors that several hundred managed to swim ashore despite the best vigilance of the small-craft navy. The natives of New Guinea, who had long chafed against the Australian law forbidding head-hunting, were unleashed by the authorities and had a field day tracking down the few Japanese who made it to the beach.
Eighteen Japanese made an astonishing 400-mile voyage through PT-patrolled waters to a tiny island in the Trobriand group. They were captured by the crew of PT 114 in a pioneer landing party operation of the PT fleet.
The skip bombers of the American Air Force had sunk four destroyers and eight transports, killed 3,000 Japanese soldiers and sailors, and shot down 30 planes. The Battle of the Bismarck Sea was a smashing blow to the Japanese, and they never again risked a surface transport near eastern New Guinea (except for a one-night run of four destroyers in a feeble and abortive attempt to set up a spurline of the Tokyo Express.)
The American Navy had an official torpedo-boat doctrine, of course, and PT officers were well drilled in the proper manner of delivering torpedoes in combat before they left the States, but this night-prowling business against torpedo-proof barges called for new torpedo-boat tactics.
Lieuts. (jg) Skipper Dean in PT 114, and Francis H. McAdoo, Jr., in PT 129, tried the still-hunt methods of Mississippi, where sportsmen hide themselves beside a known game trail and let the stag walk right up to his death. On the night between March 15th and 16th, the two PTs set up an ambush in a known barge rendezvous. They slipped into Mai-Ama Bay, a tiny inlet on the Huon Gulf shoreline, which they suspected was a Japanese barge terminal, and there they cut their engines and waited. As usual, it was raining and visibility was virtually zero.
The current persisted in setting the boats toward the gulf, so the 114 dropped anchor. Lieut. McAdoo found that he was too restless for a still hunt, so he oozed the 129 back into the gulf on one engine, to see if any barges were unloading south of the entrance to the bay.
The PT sailors didn’t know it, but six Japanese barges had arrived before them and were unloading all around in the darkness. Two of the drifting barges, already unloaded and idling about the bay until time to form up for the return trip, bumped into the side of the 114. To the PT sailors it was as though a clammy hand had touched them in a haunted house. They were galvanized.
Silence and stealth were second nature to them, however, so they moved quietly to battle stations. The Japanese on the barges, happily assuming that the PT was another Japanese ship, chattered amiably among themselves.
Machine-gunners on the PT strained to depress their 50-caliber mounts, but the barges were too close. Sailors quietly cocked submachine guns instead.
At the skipper’s signal, with blazing Tommy guns, the crew hosed down the decks of the two daihatsus that were holding the PT in their embarrassingly close embrace. The PT anchor was snagged to the bottom, so a sailor parted the line with an ax, and the PT tried to put a little distance between itself and the Japanese.
The aft 50 calibers sank one barge, but the other caught under the bow of the PT and plugged its escape route. Skipper Dean solved the problem by shoving the throttles up to the stops and riding over the barge, which swamped and sank under the PT’s weight.
The 114, once free from the two daihatsus, turned back into the inlet with guns roaring. The 129 came running, and the two PTs mopped up the rest of the six-barge convoy.
The Australian army had taken on the job of throwing the Japanese out of the three Huon Gulf villages that formed the western hinge of the Japanese gate. They were doing as well as could be expected with the nasty job of fighting in the filthy jungles of New Guinea, but they were having supply problems almost as serious as those of the blockaded Japanese. The Allies had no beachhead near the Australians, and supplies, in miserly quantities, had to be flown to a jungle airstrip and packed to the troops by native bearers.
The PT fleet in New Guinea had become so sophisticated by this time that it had acquired a formal organization and an over-all commander, a former submarine skipper named Morton Mumma. Aboard one of his PTs, Commander Mumma had gone poking about the little-known shoreline around the Huon Gulf (Mort Bay was named for him, because he first explored it), and he had found a fine landing beach at Nassau Bay. The beach was right under the nose of the Japanese garrison at Salamaua, it’s true, but it was also temptingly handy to the Australian lines.
On the last day of June, 1943, three PTs packed a company of riflemen on their deck. With 36 small Army landing boats, the PTs sortied into a foul sea, lashed by high winds and rain. Total naval escort for the amphibious armada was PT 168, which presumably was in better fighting trim than the others, because it carried no seasick passengers. PT 168 promptly lost its convoy in the storm.
The Flying Shamrock (PT 142) missed the landing beach at Nassau Bay and did a countermarch. In the rain and darkness, the Shamrock beat the astronomical odds against such an accident by ramming the tiny PT 143, to the alarm of the miserable foot soldiers on both boats.
The Army landing craft scattered in the storm, and the two PTs had to round them up and guide them to the beach, where several broached in the high surf and were abandoned. Short of landing craft to put their own sea-weary passengers ashore, the PTs had to carry them back to the staging area.
Despite the less than 100 per cent efficiency of the operation, the few American soldiers who had reached the beach threw the Japanese garrison into a panic. A lucky bomb hit had killed their able commander, and without his support the 300 Japanese assigned to guard Nassau Bay broke and fled before the insignificant Allied invasion force.
Puny as they were, the landings at Nassau Bay threw the Japanese high command into a flap. They saw clearly, possibly even more clearly than the Allies, that the Nassau Bay beachhead was going to unhinge the whole Japanese gate across the Allied path. The landings also paid an unexpected bonus far to the east, where American soldiers were landing on Rendova Island, as part of the island-hopping advance up the central Solomons toward the eastern hinge of the Japanese gate. The Japanese at Rabaul were so alarmed by the minuscule PT operation at Nassau Bay that they jammed their own radio circuits with alarms and outcries. The Japanese at Rendova couldn’t get anybody to listen to their anguished cries for help, and the American troops went ashore with almost no air opposition.
Ashore on Huon Gulf, the Australians still had the uncomfortable job of convincing the stubborn Japanese foot soldiers that they were doomed, and previously the only way to convince them had been to kill them by bullets or starvation. The PTs tightened the blockade by night.
Just before the end at Finschhafen, when the Japanese were getting ready to give up the Huon Gulf, barge traffic increased. It was the same story as the earlier abandonment of Buna, Gona, and Sanananda. The Japanese were slipping out by night.
On the night between August 28th and 29th, two PTs patrolled off Finschhafen. Ensign Herbert P. Knight was skipper of the 152; Lieut. (jg) John L. Carey was skipper of The Flying Shamrock (PT 142). Riding the Shamrock, in command of the operation, was a most distinguished PT sailor, Lieut. John Bulkeley, rescuer of MacArthur, back from his tour in the United States as the number one naval hero of the Philippines campaign.
Lookouts spotted three barges, and one went down under the first attack by the two PT boats, but the other two were still afloat after the third firing run. Ensign Knight dropped depth charges alongside, but the barges rode out the blast and were still afloat when the geysers of sea water settled. Lieut. Carey made a depth-charge run and blew one of the barges apart, but the other still survived.
Aboard the Shamrock, Bulkeley decided to finish the job in the old-fashioned way—by hand.
For the first time in this century, with a cry of “Boarders away,” a U. S. Navy boarding party, weapons in hand, swarmed aboard an enemy craft. One Japanese made a move in the darkness, and Lieut. Bulkeley blew him down with a 45 automatic. The other passengers, twelve fully equipped soldiers, were already dead.
The boarders picked up what documents and equipment they thought would be interesting to Intelligence, and reboarded their PT. The 152 pumped 37-mm shells into the barge until it slid under the water.
Ashore, Intelligence captured the diary of a Japanese officer named Kobayashi. Under the date of August 29, 1943, was the entry:
Last night with the utmost precaution we were without incident transported safely by barge between Sio and Finschhafen. So far, there has not been a time during such trips when barges have not been attacked by enemy torpedo boats. However, it was reported that the barge unit which transported us was attacked and sunk on the return trip last night and the barge commander and his men were all lost.
The PT blockade at sea and the Australian drive ashore pinched the Japanese hard, and on September 16th Australian infantrymen walked into a deserted Finschhafen. The western hinge of the gate had been broken.
