The landing on Kiska, ten weeks later, was one of the greatest anticlimaxes in the history of amphibious warfare. For a week in August the island was battered by bombing raids and heavy naval gunfire. On August 15, a big transport fleet arrived and put 34,000 Canadian and American troops ashore. (The invasion force was twice the size of the one that had participated in the WATCHTOWER landings in the Solomons a year earlier.) The invaders advanced inland cautiously, but they found no one and encountered no hostile fire at all. The Japanese garrison had been evacuated under cover of fog two weeks earlier.
Considering the expenditure of naval ordnance and aerial bombs on an island that had been vacated by the enemy, and the tremendous investment of shipping and troops in a bloodless invasion, the Kiska operation had been slightly farcical. In Pearl Harbor, the news was received in good humor. Nimitz liked to tell visitors how advance elements of the huge invasion force, creeping inland with weapons at the ready, were warmly greeted by a single affable dog that trotted out to beg for food.
IN THE SOUTH PACIFIC, the Munda operation began on June 30, 1943, when Admiral Turner’s Third Amphibious Force put troops ashore on Rendova Island, five miles south of the assault beaches on New Georgia. This island would have offered an ideal platform for artillery fire directed onto the landing site, but the Japanese had not secured it and the small garrison was swiftly overrun.
With the cover provided by newly installed batteries, landing boats ferried army and marine units across the sound to New Georgia. AIRSOLS put hundreds of planes into the air to support the landing. Japanese air attacks were brushed off with little trouble, but the American ground troops ran into forceful resistance as they closed the ring around the Munda airfield. The 4,500-man Japanese garrison had dug in deeply and well, and the terrain was abysmal. The Munda campaign was a photonegative of the fight on Guadalcanal, with the Japanese and Allied positions reversed. Now it was the American soldiers and marines who struggled through swamp and underbrush, losing contact with adjacent units and suffering heavily under harassing attacks by the enemy. Japanese units launched nighttime banzai attacks, accompanied by shouted profanities and taunts in broken English. Two green American army regiments broke and ran, throwing down their weapons; several were shot by other American soldiers who mistook them for enemy, and several dozen had to be evacuated because of “psychoneurosis.” One officer recalled that fear was like a disease that spread through the ranks, eventually transmuting into mass panic. Discipline and morale crumpled. “By morning, in an unmanageable mass, men were huddling in groups along the trails to the rear and pursued savagely by the enemy that caught up with many of them and—to use an archaic phrase—put them to the sword.”28
Eventually, all available reserves were committed to the capture of Munda. Three army divisions required a full five weeks to secure the airfield; 1,195 Allied servicemen were killed in the effort. Most of the defenders died or took their own lives, but a few managed to evacuate by sea to Vila airfield on nearby Kolombangara.
As if more evidence was needed, the Allies now had another exhibit in the case against the wisdom of frontal attacks on strongly entrenched island positions. The road to Rabaul was not open. The Japanese had another dozen airfields, large and small, on islands to the north, east, and west. The complex on southern Bougainville, in particular, would require a long and bloody effort to capture. Commanders in Washington, Pearl Harbor, Noumea, and Brisbane began to study and debate the concept of bypassing or “leapfrogging” strongly defended positions, as a means to speed the campaign and contain the cost in Allied lives. Ernest King’s proposal (in March 1943) to pole-vault over Rabaul to the Admiralties had been an idea ahead of its time, but it would soon be adopted as the centerpiece of the Allies’ grand strategy in the Pacific.
In his widely read memoirs, Reminiscences, MacArthur named himself the mastermind of the leapfrogging strategy. “I intended to envelop them, incapacitate them, apply the ‘hit ’em where they ain’t—let ’em die on the vine’ philosophy,” he wrote. “There would be no need for storming the mass of islands held by the enemy.”29 The truth is that MacArthur was a late convert to the cause. Robert Carney, chief of staff to Halsey’s “Dirty Tricks Department”—the insiders’ affectionate nickname for SOPAC headquarters—recalls obstinate opposition from his counterparts in Brisbane. “MacArthur felt that you simply couldn’t go away and leave strong forces . . . upon your flank or behind you. This thinking in his outfit was quite different from the thinking in ours.”30 MacArthur apparently adopted the leapfrogging philosophy some time after the bypass of Rabaul was ordered by the Combined Chiefs of Staff (the American-British supreme command) in August 1943. Even then, he initially opposed several bypassing maneuvers, notably Halsey’s leap past Kavieng in March 1944.
Immediately northwest of New Georgia was the island of Kolombangara, a perfectly round stratovolcanic cone soaring out of the sea to an altitude of 5,800 feet. A Japanese garrison was dug in at Vila Airfield, on the island’s southern shore. Admiral Kusaka expected the next amphibious landing to fall on Vila, and had been reinforcing the position for weeks. Japanese troop strength in the perimeter had reached about 10,000 troops, more than double the number the Allies had faced at Munda. On August 15, the Third Amphibious Force instead circumvented Kolombangara and seized a beachhead on the island of Vella Lavella, about fifty miles north, where the enemy garrison numbered only 250 men. The invasion force suffered minimal casualties, and the Seabees had a new airfield operating within three weeks. Realizing that Kolombangara was to be ignored by the enemy, Admiral Kusaka ordered the garrison evacuated to Bougainville, under cover of darkness, by submarines and destroyers.
In attempting to reinforce their beleaguered positions in the New Georgia group, Japanese cruiser and destroyer squadrons clashed with Allied task forces in several minor naval battles. The Japanese retained their customary excellence in night torpedo actions, and their Type 93 “Long Lance” torpedoes remained the best weapons of their kind in the theater, but the Americans were learning to use their superior radar systems to advantage. Each ship now correlated information from radar and other sources in the Radar Plot, which later evolved into the Combat Information Center (CIC). During this period the U.S. Navy also benefited from the exceptional leadership of seagoing commanders such as Rear Admirals Walden Lee “Pug” Ainsworth and Aaron Stanton Merrill, and Commander Frederick Moosbrugger and Captain Arleigh “31-Knot” Burke. During the battle for Munda, Admiral Ainsworth twice intercepted inbound Japanese forces at the Battles of Kula Gulf (July 6) and Kolombangara (July 13). In each engagement, the Americans approached in a single column with cruisers in the center, fired on the lead ships in the Japanese column, and then turned away to avoid the inevitable torpedoes. In both battles, the Allies and Japanese suffered in about equal measure; in each, the Japanese force was beaten back and failed to reinforce Munda.
On the night of August 6–7, Commander Moosbrugger led a division of six destroyers in two parallel columns (the tactic had been developed by Burke, recently recalled to higher command) against another incoming Japanese squadron. One column fired a spread of torpedoes and turned away. As the Japanese fired on the withdrawing ships, the second column crossed the enemy’s “T” and opened a devastating salvo of gunfire. Three Japanese destroyers, crammed with troops intended for Kolombangara, blew up and went down. One spectacular explosion, as described by one of the American action reports, “took the form of a large semicircle with the water as the base, extended six to seven hundred feet into the sky.”31
A thousand Japanese soldiers and sailors were killed in the explosions or drowned afterward. Tameichi Hara, commanding the one Japanese destroyer to escape the action, concluded that “the enemy had ambushed us perfectly.”32 The tactics employed by the Americans in this “Battle of Vella Gulf,” faithfully executed by Moosbrugger, served as a template for several surface actions to come in the fall of 1943.
The tide of battle in the South Pacific had deci
sively turned. Japanese naval operations became increasingly concerned with evacuating troops as their positions grew hopeless. During the retreat from Kolombangara, the Japanese had established a staging base for barges and landing craft at Horaniu, on the northeast shore of the island of Vella Lavella. An Allied landing at Horaniu on September 14 dislodged the 600-man Japanese garrison and sent them in a disorderly overland retreat to Marquana Bay on the northwest shore. Admiral Kusaka ordered a rescue operation. Rear Admiral Matsuji Ijuin sailed from Rabaul with a force of six destroyers and two transport groups, the latter including three transport destroyers. About twenty small craft joined up from Buin on southern Bougainville.
On October 6, this small armada—seemingly disproportionate to the task at hand—was discovered by American air search. Six American destroyers were in the area, and they moved to intercept, but they were divided into two divisions separated by about twenty miles. The northern group—the Selfridge, Chevalier, and O’Bannon, under Captain Frank R. Walker—charged into action without waiting for Captain Harold O. Larson’s southern group (the Ralph Talbot, Taylor, and La Vallette). Since the days of John Paul Jones, American naval lore had honored and applauded the bold attack on superior enemy forces. In this case, however, Walker’s daring proved rash. His three-destroyer squadron advanced on Ijuin’s nearest division of four destroyers and fired projectiles and torpedoes. Ijuin turned away and blew a smoke screen to cover his withdrawal, but one of his destroyers, the Yugumo, continued toward the Americans and exchanged fire as she closed. She was lit up by at least five 5-inch shell hits and quickly exploded into flame. A few minutes later, Walker’s ships ran into a deadly spread of Long Lances. The Chevalier and the Selfridge each had their bows torn off, and the O’Bannon was unable to avoid colliding with the injured Chevalier. The Selfridge continued firing gamely on the second division of enemy ships, passing in column at a range of about 11,000 yards, but took a torpedo in her port side at 11:06 p.m. The Chevalier was finished, while the heavily damaged O’Bannon and Selfridge managed to hobble back into Purvis Bay. As the Americans cleared the area, the Japanese small craft completed the evacuation of the troops at Marquana Bay. The Japanese had won a tactical and strategic victory in this “Battle of Vella Lavella.” It was to be their last sea victory of the war.
At the first Allied conference in Quebec (code-named QUADRANT and held in August 1943), the British chiefs—tilting toward any arrangement that would release more forces to the campaign against Nazi Germany—had backed King’s case to consolidate offensive resources into a single drive across the central Pacific. That would have sidelined the South Pacific operations and marooned MacArthur in a strategic backwater. FDR was swayed by Marshall’s insistent demands to continue the southern push toward the Philippines. The president was likely influenced by MacArthur’s political weight and his implicit threat to accept the Republican nomination for the presidency in 1944.
Pursuant to the conference directives, the Combined Chiefs of Staff (CCOS) promulgated a revised plan entitled RENO III, which directed MacArthur to “seize or neutralize Eastern New Guinea as far west as Wewak and including the Admiralties and the Bismarck Archipelago. Neutralize rather than capture Rabaul.”33 The document reasoned that “direct attack to capture Rabaul will be costly and time-consuming. Anchorages and potential air and naval bases exist at Kavieng and in the Admiralties. With the capture and development of such bases, Rabaul can be isolated from the northeast.”34
The next and last major landmass on Halsey’s road to Rabaul was Bougainville. Here the bypass principle would again save time and lives. The Japanese had poured troop reinforcements into its bases on and around the island—at Buin and Shortland in the south, and at Buka and Bonis in the north. By mid-October, total Japanese strength in these areas exceeded 40,000 men. Halsey and his Dirty Tricks Department elected to land forces on the west coast, at Cape Torokina in Empress Augusta Bay, where the enemy presence was negligible. By now the pattern was familiar. Assault troops stormed ashore, heavy equipment and munitions followed behind them, the forces established a strong perimeter, and Seabees raced to build a working airfield. The Japanese army would naturally counterattack—but to do so they were obliged to struggle over primitive jungle terrain, their strength draining away by starvation and disease, before running up against well-entrenched American defenders.
For this operation (CHERRY BLOSSOM), Halsey could muster about 34,000 troops under the command of General Vandegrift—the 3rd Marine Division and the army’s 37th Infantry Division, combined into the First Marine Amphibious Corps. As an immediate prelude to the landings, the New Zealand 8th Infantry Brigade Group seized the small Treasury Islands. On November 1 before dawn, 3rd Division marines stormed ashore at Cape Torokina from a dozen transports and swiftly overpowered the meager Japanese forces in that area. Furious air battles raged overhead throughout the day, but the AIRSOLS fighters managed to prevent any sustained attack on the beachhead. Kenney’s Fifth Air Force poured an unprecedented amount of punishment down on Rabaul’s airfields to suppress the Japanese air response. By nightfall, 14,000 troops were safely ashore with 6,000 tons of equipment, munitions, and supplies.
The Imperial Japanese Navy was determined to interrupt the operation. Kusaka organized a cruiser-destroyer task force at Rabaul and sent it south under the command of Rear Admiral Sentaro Omori. This force was discovered by air search as it steamed down the Slot, and Halsey ordered his only naval force in the area, Admiral Merrill’s Task Force 39, to protect the beachhead. The crews of Merrill’s four light cruisers and eight destroyers had been hard at it for more than twenty-four hours and were nearing the point of exhaustion, but no other forces were on hand. Merrill employed the tactic of deploying his destroyer divisions in a separate group to launch unseen attacks on the enemy’s flank. His cruisers guarded the approach to the beaches, kept up a continuous fire with their 6-inch guns, and looped around in coordinated “figure-8” patterns to confuse the enemy and avoid his torpedoes. Arleigh Burke, recently promoted captain, commanded Destroyer Division 45. The tactics had been well rehearsed, and the commanders were perfectly attuned to one another.
James Fahey, a sailor on Merrill’s flagship Montpelier, described a long night illuminated by lightning, flares, star shells, and muzzle flashes. “The big eight inch salvos, throwing up great geysers of water, were hitting very close to us,” he recorded in his diary. “Our force fired star shells in front of the Jap warships so that our destroyers could attack with torpedoes. It was like putting a bright light in front of your eyes in the dark. It was impossible to see. The noise from our guns was deafening.”35 Merrill’s ships destroyed a Japanese cruiser and destroyer and drove the intruders away, securing the beachhead. Two American ships were disabled, but none were lost.
Admiral Koga sent another cruiser-destroyer task force down from Truk, under the command of Vice Admiral Takeo Kurita. When Kurita’s ships were sighted by AIRSOLS scouts north of Rabaul on November 4, Halsey decided to deploy his two available carriers, the Saratoga and the light carrier Princeton. As heavy attacks on the airfields in and around Rabaul kept Japanese airpower on the defensive, the carriers charged into the Solomon Sea. On the morning of November 5, a massive ninety-seven-plane strike rained bombs down and launched aerial torpedoes on the Japanese fleet, inflicting ruinous damage on seven cruisers.
A week later, three American carriers on loan from the Fifth Fleet (then moving toward the Gilbert Islands to strike the opening blow in the central Pacific offensive) detoured south and launched another attack on the Japanese fleet at anchor in Rabaul’s Simpson Harbour. One was the recently commissioned Essex, namesake of a new class of fleet carriers that would dominate the air war as the fight moved into the western Pacific in 1944 and 1945. More than a hundred Japanese aircraft attacked the carrier group, and the executive officer of the Essex, Fitzhugh Lee, recalled an edgy night in the ship’s Combat Information Center: “We were trying to use our new radar, which worked well at long ra
nge in the early stages of the battle, but it soon became too much of a melee in which we didn’t know whether we were shooting at our own planes or the Japanese planes.”36 Lee was surprised and relieved that the Essex avoided taking a single bomb or torpedo hit in the action, and that it came through unscathed except for a few bullet wounds in strafing runs. The Japanese lost forty-one of the planes committed to the attack. In Nimitz’s view, the November 1943 carrier strikes on Rabaul “settled once and for all the long-debated question as to whether carriers could be risked against powerful enemy bases.”37 Admiral Koga summoned the surviving elements of his fleet back to Truk.
Beginning in December, the skies over Rabaul were darkened by Allied bombers from dawn to dusk. For the defenders on the ground, their only respite from unremitting aerial punishment came when the weather closed in and cut visibility to zero. Kenney’s Fifth Air Force pummeled the airfields and supporting installations. Marine Major General Ralph J. Mitchell took over as commander of AIRSOLS, but most of the previous staff was kept in place. (AIRSOLS had become, perhaps, the single-best-integrated multiservice command in the world.) Mitchell began moving units northwest from months-old airfields on New Georgia and Vella Lavella to his new airfields on the Treasury Islands and at Torokina on Bougainville. Shorter-legged navy and marine fighters and bombers could now comfortably reach Rabaul, and began pouring down destruction on the Bismarcks in hundreds of daily sorties. Admiral Koga continued feeding air reinforcements into the theater from Truk, including his last reserve of trained carrier airmen. The South Pacific had become a meat grinder for Japanese airpower.
