Last time we spoke about General Patchs campaign to finally rid Guadalcanal of the Japanese menace. The Sea Horse, Galloping Horse and Gifu were neutralized and now the hybrid force of US Soldiers and Marines were marching west. The newly created CAM division seized Kokumbona in astonishing speed, greatly hindering the future Operation KE. At the same time, all of the Japanese activity related to preparing Operation KE was prompting responses from the Americans. One of those responses was sending Rear Admiral Richard Giffen to Cape Chunter to rendezvous with Captain Robert Briscoe. Giffen was stubborn about making his rendezvous and this led him to make some very poor tactical decisions leading to the sinking of the USS Chicago during the battle of Rennell Island. Despite the sinking of the cruisers, the Japanese now had to push back Operation KE until February the 1st, would this setback ruin everything?
This episode is Operation KE: the Evacuation of Guadalcanal

Last week we spoke about the rather small battle of Rennell Island. Perhaps small in scale, but the consequences of the battle were far reaching. Operation KE had to be postponed until February 1st. Alongside this there was some shuffling about for who was to command the Reinforcement unit, and eventually it landed in the hands of Admiral Shintaro Hashimoto, with Rear Admiral Koyanagi in a reserve capacity. The 11th air fleet and the 6th air division were tasked with maintaining the CAP over the reinforcement unit during the day, while the R Area air force would cover them during the night. Now the skirmish at Rennell Islands gave the IJA and IJN a dose of anxiety, because the islands had a critical role in Operation KE. Basically if the destroyers failed to evacuate the 17th army on Guadalcanal, the backup was to be landing crafts via Russell Island. Many staff officers also sought to create a temporary garrison and base in the Russells to be a feint. Thus on January 28th, 6 destroyers bearing 328 men went to the Russells and were attacked by 33 aircraft from the cactus airforce, leading to 17 casualties, but no warship damage.
The day for Operation KE to commence had finally come and it was to begin with a short battle over the air. 9 B-17’s with their fighter escort bombed Shortland at 8:45. They were unable to damage or delay Operation KE very much and lost 3 B-17’s for their efforts. Likewise the Cactus air force lost 2 dauntless attacking Munda while the 6th air division tossed 23 Oscars and 6 Lilies at Guadalcanal. On February 2nd, General Patch concluded that with the seizure of Kokumbona, this must mean the Japanese were all but finished on guadalcanal, unless more reinforcements came. He presumed they would prolong the struggle by making a fighting withdrawal to the southern coast, so to thwart this possibility he decided to land a battalion in a blocking position.
Lt Colonel George commanding the 132nd infantry assembled a task force at Lunga using his 2nd battalion with various other units, one of which was a howitzer company of the 10th marines. The men loading up in some Landing Craft Tanks aboard the destroyer transport Stringham. Captain Briscoe’s Cactus striking force escorted the group as they traveled to Nugu point, but when they were unloading they received news of nearby enemy activity, thus an emergency unloading was made 1.5 miles north at Verahue. An IJA reconnaissance pilot saw this and misidentified the destroyers as cruisers and reported this giving the Japanese the idea the Americans were about to challenge their first Reinforcement Unit run. Thus to clear a path for Operation KE’s first run, a group of 13 vals and 40 zeros was launched from Buin to take out the threat. At 2:43, guadalcanal issued a condition red alert, and this led to a grievous mistake. The destroyers DeHaen and Nicholas had shepherded the remaining landing craft tanks 2 miles southeast of Savo, but the fighter director scrambled all the wildcats to go protect the other destroyers of the Cactus striking force. Thus DeHaven and Nicholas were dangerously exposed without aircover when some of the Vals found them. 6 vals attacked DeHaven, with the first bomb hitting her at 2:53 amidships on her port side. An eye witness said it “caused tremendous burst of flame to envelop the central part of the ship.” A second bomb hit just aft of her bridge and a third exploded her forward magazine. The Dehaven jackknifed and disappeared under the waves claiming 167 men and officers with her.
Over on the Nicholas, Lt commander Andrew Hill barely managed to evade the bombs taking his ship 32 knots. One bomb exploded near his ships hull killing 2 men and injurying 7, but the Nicholas returned the favor by taking down 3 aircraft while some Wildcats came to the scene eventually claiming a dozen kills. The actual Japanese losses would be 5 vals and 3 zeros. As this was going down, Admiral Hashimoto left Shortland with his Cruisers and 21 destroyers sprinting down the slot. A coast watch saw Hashimoto’s reinforcement unit just due north of Vella LaVella around 1pm, prompting the Cactus air force to toss up 92 aircraft in 2 waves. The first wave consisted of 17 avengers, 17 dauntless, 4 P-39’s, 4 P-38s, 4 p-40s and 5 Wildcats. The second wave consisted of 11 avengers, 10 dauntless, and 20 wildcats. The first group claimed the sunk a destroyer and 7 zeros while the second claimed they landed 2 bomb hits on destroyers and took down 10 zeros. During the actual attack, Hashimoto’s flagship the Makinami received a near miss, while Koyanagi took charge of the flotilla. Hashimoto was forced to move his flag to Shirayuki and gradually reigned back command. The shuffling set back the force 30 minutes and at 8pm the screening ships began peeling off to conduct a sweep ahead. While this was happening 11 PT boats from Tulagi came in groups of 2 and 3 from Savo, Cape Esperance and Doma Cove to hit the reinforcement unit.
Meanwhile on Guadalcanal, Generals Miyazaki and Sano had reached their boarding point at Cape Esperance around 8pm. Thousands of their men were making the grueling trek up muddy trails through the night. Miyazaki was frustrated by the man wandering from the designated area and making too much noise, then both he and Sano heard a single rifle shot. A staff officer was sent to investigate and he came back reporting a soldier of the 229th infantry had reached the area supported on the shoulders by 2 comrades. He was unable to move any further, and his comrades were exhausted, thus he received his comrades assistance to commit suicide. The reinforcement unit was set to arrive for 9pm, but minutes were passing by 9pm without a ship in sight. Then the Japanese began hearing gunfire and saw fires emerge seward.
The reinforcement unit were pulling 30knots when PT boat 48 and 111 found them around 10:10pm launching 4 torpedoes. Lt Lester Gamble, the most successful PT skipper of the Guadalcanal Campaign managed to scurry his PT 48 away, fleeing to Savo, while Lt John Clagett aboard PT 111 took a direct hit from the Kawakaze at 10:54 killing 2 men. Off of cape esperance, Japanese float planes strafed PT 59, 115 and 37. PT 115 launched 4 torpedoes at the destroyers. PT 37 also fired 4 torpedoes, but was fired upon killing all but a single man aboard. PT 124 and 123 moved in to attack south of Savo. A Pete of the R Area air force managed to plant a bomb on PT 123 killing 4 and sinking the boat, an amazing hit. PT 124 fired 3 torpedoes claiming hit, bringing the American loses at 3 PT boats and 15 dead sailors.
The R Area air force Petes began to drop flares over the Cactus striking force which now was just 3 destroyers trying to harass 18 IJN destroyers. The Pete flares thwarted any chance of surprise. 6 transport destroyors reached Cape Esperance at 10:40 and at 12am, Kamimbo began to launch their boats. Admiral Koyanagi described the sight of the evacuees as such;
“[They] wore only the remains of clothes [that were] so soiled their physical deterioration was extreme. Probably they were happy but [they] showed no expression. All had dengue or malaria [and their] diarrhea sent them to the heads. Their digestive organs were so completely destroyed, [we] couldn’t give them good food, only porridge.
A report informed Admiral Yamamoto that the evacuees . . . were so undernourished that their beards, nails and hair had all stopped growing, their joints looked pitifully large. Their buttocks were so emaciated that their anuses were completely exposed, and on the destroyers that picked them up they suffered from constant and uncontrolled diarrhea.”
By 1:53am the last man board at Kamimbo and 5 minutes later over at Esperance. Because of all the delays, 1270 men were stuck on the beach at Cape Esperance and 300 over at Kamimbo. The Destroyer Makikumo was chasing away one of the PT boats when she was ordered to help at Cape Esperance. When she was heading over a large explosion suddenly occurred in her hull at 1:45am. It could have been a mine, or perhaps one of the PT torpedoes had finally hit its mark. Regardless, the Makikumo was dead in the water and forced to be scuttled by a sister destroyer, the Yugumo. The 11th air fleet launched 8 Betty’s over Guadalcanal during the night to keep the Cactus air force grounded, but 6 Dauntless managed to get up around midnight. Despite the enemy being illuminated well, the dauntless did not manage to score any hits. At 8am the Cactus air force made another go trying to hit the enemy destroyers, but failed to score any hits. By noon the reinforcement unit successfully landed 4935 men at Bougainville, including General Sano.
The first run was a large success and helped boost morale for the 17th army HQ, as they were quite frankly fearing the worst. As a deception, they had the soldiers over at Cape Esperance ignite campfires and move them gradually south towards Tassafaronga over the course of 2 nights. Meanwhile the 2nd division began to march in the opposite direction towards their own disembarkment points. On February 3rd, the 8th area army ordered the next run to have soldiers and sailors wait offshore in boats rather than on the beach. Despite the success of the first run, the 17th Army was still skeptical about the IJN making 3 runs. This led them to dispatch orders to Colonel Matsuda incharge of the rear guard, warning him it may be likely that he would have to make his own way out with a landing craft.
The Japanese high command was also gravely concerned with a growing situation at Marovovo. Lt Colonel Georges battalion had successfully departed from Verahue and around 9:10am one of their patrols ran into a pair of Japanese staff officers and 140 soldiers near Titi. There was a brief skirmish and the Japanese captured 2 of Georges men who were interrogated, revealing that around 600 of their comrades were marching around Marovovo. On the morning of February the 3rd, Matsuda’s rear guard of 350 troops of the Yano battalion were holding a position about half a mile west of Bonegi, alongside 60 survivors of the 124th infantry. His main force consisting of the remnants of the Ichiki detachment, which is simply incredible that any of them still exist at all at this point, alongside the 124th regiment were holding the right bank of the Segilau river. Fortunately for Matsuda the Americans were limiting their actions mostly patrolling for the day and he used the time to plan out the evacuation of his rear guard. His general plan was to lead his forces to Kamimbo and disembark to the Russells by boat.
The next day General Patch ordered his 161st infantry to relieve the 147th infantry, taking their job of advancing to Cape Esperance. The 147th would head west to an area between Bonegi and the Umasani rivers to clear out the area. 128 men under first Lt Miyano were ordered to hold the eastern bank of the Segilau river and Major Yano was ordered to leave a rear guard of 70 men to the west of Bonegi before he took the rest of his command to advance on Marovovo. Major Yano strongly objected to performing actions at Marovovo and that his units would be better served remaining with the rear guard. Basically Matsuda was ordering Yano to leave men to die at Bonego and Yano began to argue all his men should make a stand if so. So Matsuda caved in a bit and allowed Yano to leave only those unable to walk at Bonegi while he took everyone else to Segilau at 3pm. For those poor men left at Bonegi, each was given 2 tablets of mercury bichloride.
From February 2-4th around 15 Bettys hunted the sea around guadalcanal and they reported very strong American naval presence, including carriers. Each day saw more bettys failing to return home, one of which carried Lt Commander Genichi Mihara the leader of the 705th air group. Despite the presence of many american naval units, on February 3rd the second run of Operation KE was approved to go. Admiral Yamamoto ordered the Asagumo and Samidare to replace the lost Makikumo and Makinami and on february the 4th, Hashimoto readied his cruisers and 20 destroyers to dare another run. His reinforcement unit left Shortland at 11:30 and at 3:50 his CAP of 29 Zeros clashed with 33 dauntless and avenger alongside 41 assorted fighters in two waves trying to take out his destroyer. The Americans lost 11 aircraft while the Japanese lost 2. A near miss crippled the Maikaze, forcing the Nagatsuki to tow her back to shortland and yet again Hashimoto was forced to change flag as the Shirayuki’s engines failed and thus he jumped onto the Kawakaze.
Over on Guadalcanal 7 Bettys emerged at night dropped flares and bombs over Henderson field while IJN reconnaissance planes hunting PT boats. The embarkations proceeded smoothly, in 2 hours 3921 men were loaded off. General Hyakutake and his staff boarded the Isokaze, Maruyama and his staff got aboard the Hamakaze and both transport groups left with their screens completely unmolested up the slot, reaching Bougainville by 12:50 on february 5th. Miyazaki recounted seeing countless soldiers aboard the Isokaze sun bathing, as they had been long denied such a pleasure. There was nowhere to walk about the destroyers decks. He also found a soldier holding a corpse of a friend aboard, insisting the man was still alive. On Bougainville, Lt General Moritake Tanabe, the deputy chief of stuff of the IJA’s section of the Imperial General HQ met the evacuees. Miyazaki exchanged a wordless salute with the man, then as Tanabe approached him, he blurted out with tears, his desire for an appointment that would give him a death in battle. Tanabe was quite overcome by this and stated “Everything about this is the responsibility of Imperial Headquarters.”
As Operation KE was whisked away men, the Yano unit withdrew from Bonegi to the Segilau river. Colonel Matsuda now took charge of the forces left on Guadalcanal as he took his men from Segilau over to Kamimbo. He ordered the Oneda Unit, consisting of the remnants of the 3rd battalion, 230th infantry to head west of Cape Esperance to block any american advances from Marovovo. Now Matsuda pondered how he was going to evacuate his rear guard. Lt Colonel Sakuji Matsuyama gave his very pessimistic view, the American air forces would whittle down the amount of boats available to them to most likely just a handful. They also received word from a tapped signal to the IJN on Rabaul that they were looking to use at minimum 3 or 4 destroyers with an adequate number of boats to be detailed for the final run. Thus Matsuda figured any attempt to evacuate the rear guard to the russells by boat would be suicidal. Matsuda wrote in his diary that night he doubted any destroyers would come, from his perspective, the sacrifice of 2000 men would be less than that of a single destroyer.
Over on the American side, Colonel George’s men reached Titi on the 4th and would remain there for 2 days. Because of the smaller size of his command and not fully knowing the Japanese composition forced George to act cautiously. All of the Japanese activity had really confused the American’s and they presumed there was a major offensive afoot, there was of course just not what the Americans were thinking. Over on the west coast the 161st infantry advanced to the Umasani river by February 6th. Despite the apparent American inactivity, Matsuda feared that if they decided to make a thrust from the southern coast this would cut him off from Kamimbo and thus an embarkation spot. To keep this option open, he sent 100 men to move down the west coast to hold a position about 3.5 miles due east of Cape Esperance. He ordered them to march during daylight and to light cooking fires as a deception. Later that afternoon he received the demoralizing report that the IJN might only be able to pick up men already waiting in boats, those on the land would have to find their own way to new Georgia.
The 17th army estimated that Matsuda had a 50% chance of getting the men out. On the 6th, senior IJA and IJN commanders met over the issue. The chief of staff of the 8th fleet said he doubted the third run of operation KE would be possible because there were reports of American carriers near guadalcanal. Admiral Mikawa assured the IJA, the IJN would do its best to meet the enemy. Colonel Konuma went to see Admiral Hashimoto to fish out his views, and Hashimoto asserted regardless of the orders or desires of the chief of staff of the 8th fleet, he would personally see to it that they evacuated all the men. Konuma requested to accompany the 3rd run personally. Hashimoto said to this it would be a stain on the IJN’s record if it was said they only made a run because an Army officers presence aboard their ships was the causation.
On the 7th, General Patch reported his belief that the Tokyo Express had made to successful runs, landing another regiment with supplies. Though in the same report he also acknowledged they may have extracted the HQ of some depleted units as well. Over on the west coast, 161st tossed patrols near the Tambalego river, 9 miles away from Cape Esperance. That day Colonel George had to hand command of his task force over to Lt Colonel Ferry after injuring his leg. Upon taking command, it was Ferry’s judgment that the Japanese were withdrawing to Cape Esperance or perhaps evacuating guadalcanal. Their native guides began reporting to them that the Japanese had just abandoned Marovovo, so the task force marched upon it. At 12:40, the units assigned to guard Marovovo did abandon it stating they had been subjected to severe artillery bombardment, earning anger from Matsuda who demanded they go back to prolong the american advance. They rushed back just in time to fire their machineguns at the Americans who were advancing 2000 yards north of Marovovo by 3:30pm. Meeting resistance, Ferry told the men to dig in for the night.
February 7th was a day of decision making for Matsuda. Ever hour brought him more stress, the severe shelling that was reported to him at Marovovo could be heard alongside American machine gun fire at Kamimbo. Then at sundown, 26 land craft still remained operational, it was a miracle american air forces had not destroyed them all! Compared to the experiences of the entire guadalcanal campaign, it really did seem a miracle. Matsuda set to work organizing his boarding plan to provide for 4 units of 500 men each. In a very tense 45 minutes starting at 9:30pm, the remaining movable Japanese survivors of guadalcanal got onto the boats as American artillery could be heard smashing Segilau. On the boats many Japanese prayed, the rendezvous time of 11pm passed, greatly demoralizing them. Then they saw the blue recognition lights of approaching destroyers.
The second run of operation KE went off very well compared to the first. But Admiral Yamamoto suspected the third would see major american naval forces that were lurked around just outside their search plan range waiting to pounce. The submarine forces combed the area without success as the Advance force was ordered to come within 550 miles of Guadalcanal to be ready to support the Reinforcement unit. Hashimoto would have 18 destroyers this time, grabbing men from two points, Kamimbo and the Russells. Despite reported sighting of American carriers and other naval units just due south of San Cristobal, Hashimoto departed Shortland and made one last sprint to save the men of starvation island. 15 Dauntless, 20 wildcats and a single F5A bore down upon the reinforcement unit after a search plane tipped them off. 17 out of 49 zeros sent by the 11th air fleet intercepted them. At 5:55 the Isokaze was hit by 2 bombs to her deck and around her forward gun mount killing 10 men and starting fires. She limped away with the help of the Kawakaze as the Urakaze took a near miss doing slight damage. One zero and the F5A failed to return home.
Over on Guadalcanal, the men in their boats climbed aboard the destroyers. By 12:04am, on the 8th, Matsuda received word that the boarding was complete. To honor Hashimoto’s pledge, the sailors had even rowed boats along the shore waters calling out again to make sure no one was left behind on the beaches. By 1:32am, the boats returned and the destroyers began to depart. It was to be the last time the Rising Sun fluttered from a surface ship near the blood soaked shores of Guadalcanal. On the way Matsuda signaled the 17th army “With the help of 20,000 souls the recovery of 1,972 men from Guadalcanal is reported complete.” When Matsuda reached Bougainville at 10am, he reported to General Hyakutake the end of his special mission, adding thanks for the 17th army’s efforts to guarantee the last run made it. Hyakutake praised Matsuda’s command as the rear guard. As Matsuda and Hyakutake pointed out and so will I here, the first unit to fight on Guadalcanal was the Ichiki detachment and they were amongst the last to leave on the third run of Operation KE, simply incredible.
Operation KE was an enormous feat, over 10652 men were evacuated with 4935 on the first run, 3921 on the second and 1796 on the third. For naval units they had lost the Makikumo and major damage was dealt to the Makinami, Maikaze and Isokaze. They sank the Chicago, DeHaven and 3 PT boats, while also heavily damaging the LaVallette. For the air war, between January 25th to February the 9th the Japanese lost around 56 aircraft while taking down 53 American. Needless to say, Operation KE was a major success from a figures point of view. The Japanese attributed the success of Operation KE to the careful planning by the combined fleet and to those men who sacrificed their lives prolonging the American pursuers on the ground. After receiving word that the Reinforcement unit returned on the morning of the 8th, Admiral Yamamoto commanded all units involved.
The American forces at Marovovo after observing the sea littered with small boats and debris from the nights activities set off in hot pursuit, reaching Kamimbo at 5pm. During these hours over on the western coast the 161st pushed towards Cape Esperance where they ran into sporadic skirmishes with the Japanese, but the enemy they skirmished with were in extremely poor condition, mostly wounded men unable to walk. Based on the condition of the enemy, Colonel Dalton of the 161st sent a report that he believed the enemy was not defending nor delaying, but actually fleeing. General Patch concurred with this and advised Hasley that be believed the last Tokyo Express runs were not reinforcements but rather evacuations.
On the morning of the 9th, the 1st battalion, 161st infantry met up with the 2nd battalion of the 132nd at the village of Tenaro. Colonel Dalton shooks hands with Major Butler of the 132nd at 4:50, then General Patch announced to the men “Total and complete defeat of Japanese forces on Guadalcanal effected 1625 today. . . . [the] Tokyo Express no longer has a terminus on Guadalcanal.” Now there were of course Japanese left behind on Guadalcanal, but organized resistance was all but over by the 9th. Encountered with some isolated pockets and stragglers occurred for the next few days. Some stragglers would go on to live within the interior with the last known survivor surrendering in October of 1947.
Given the vast disparity in fire power between the two sides on guadalcanal and likewise the severity of how debilitated the 17th army was compared to General Patchs soldiers and marines, the failure of the Americans to annihilate Hyakutakes men was strange. Hyakutake believed that if the Americans had focused on marching towards Cape Esperance, they would have completely destroyed his army. The failure to do so was because of 2 major reasons. The first was the relatively small size of the forces engaged in the pincer attack against Cape Esperance. After January 25th, the American forces typically involved no more than a regiment on the western coast. After February 1st this was supplemented by an additional battalion on the southern coast. The second reason was the pace of the advance of those forces which was hindered by a combination of logistical factors, rough terrain and the Americans thinking an offensive was about to kick off any moment. The logical way the Americans could have foiled operation KE would have been something Vandegrift repeatedly had done, amphibious hooks. General Patch considered this often in mid January, but again, all the indications from the Japanese activity was a major offensive was about to occur, and you simply don't toss units into the abyss. Admiral Nimitz confessed in his report
“Until the last moment it appeared that the Japanese were attempting a major reinforcement effort. Only skill in keeping their plans disguised and bold celerity in carrying them out enabled the Japanese to withdraw the remnants of the Guadalcanal garrison. Not until all organized forces had been evacuated on 8 February did we realize the purpose of their air and naval dispositions. “
It has been 6 months of blood sweat and tears over 2500 square miles of jungle that was called Guadalcanal. She was in American hands, the great prize being her airfield capabilities. Both the Japanese and Americans knew her worth and both sides evaluated the costs and returns of trying to hold her. Now I have said it quite a few times, when it comes to turning points or quote en quote “the turning point” of the pacific war, a lot of people generally fall victim to the allure of the battle of midway. Sure thing the battle of midway was a turning point, but in comparisons to Guadalcanal it is arguably not as important. Midway halted the Japanese from further major operations in the Central Pacific. It thwarted Yamamoto’s attempt to create more favorable conditions militarily and diplomatically to bring American to the negotiating table. Midway also caused severe losses to the IJN, but did the Japanese go on the defensive? No they did not, in fact they immediately tossed a large scale operation against Port Moresby. Given the Japanese took Port Moresby, the course of the war would have dramatically changed, it was a pivotal place to hold. The Japanese were not simply on the defensive footing awaiting counter attacks from the enemy after midway, they still held the initiative. If you look at what the Japanese military high command was thinking directly after Midway, you find they all believed, falsely mind you, that the allied counterattack would commence no earlier than 1943, probably even later. This was not a stupid conclusion by the way, if we look at the situation in Europe, it did not seem possibly a nation like America could allocate that many resources to the pacific at the time.
General Douglas MacArthur and Admiral King aggressively pushed for offensives in the south pacific, albeit for differing reasons. MacArthur wanted to leap to Rabaul, which was obviously insane and the Navy rightfully pushed back against this. Kings proposal was much more realistic and won the day in the end. Its incredible given hindsight, that the American offensive in the south pacific began when it did. They had little in land based or carrier based aircraft, not to mention limited amphibious shipping. Yet Kings insistence produced great reward, they achieved tactic surprise and a strategic surprise of great magnitude. The Marines on guadalcanal reaped the benefits of the surprise for a long time. Given what the Japanese were capable of doing, their response to the landings on Guadalcanal was a terrible miscalculation. It took the Japanese far too long to figure out Guadalcanal was potentially the decisive battle they sought. Operation WatchTower held countless flaws that could have been exploited by the Japanese to produce a major victory. The American navy in the pacific could not hope to challenge the Japanese even after Midway, so much of their strength lay in the battle over the Atlantic, but Guadcanal offered them a unique chance to boost their ground and aerial forces in the Pacific, dramatically compensating for the lack of carriers.
With the victory over Guadalcanal, the Americans would develop it and Tulagi in major bases to support the allied offensive up the Solomons. Extensive airfields, naval ports and other logistical facilities would be built up. The Japanese had lost the initiative for the Pacific War, now they were on the defensive in the Pacific. The fall of Guadalcanal went hand in hand with the campaign in New Guinea, Japan kept juggling both campaigns and each suffered because of the other. The IJA and IJN were not beaten of course, but now the allies were in the driving seat for once.

The allies had finally seized guadalcanal and now the Japanese were on a defensive footing, they had lost the initiative for the pacific war. Things were going to dramatically change for the empire of the rising sun who now would look to a new strategy, that of bleeding the allies dry.
