/Last time we spoke about the fall of Attu. The Americans had to fight both the Japanese and a very cruel mother nature to claim the frigid island of Attu. The Americans gradually seized every hill, ridge and razer edge crest as the pushed the Japanese into Chichagof Harbor. Once the Japanese had their backs to the sea and nowhere left to withdraw, Colonel Yamasaki decided they would go out in ablaze of glory. Nearly 1000 screaming Japanese performed a suicidal Banzai charge towards the American artillery positions, hoping to unleash the enemies guns upon them. Yamasaki received an M1 Garand Bullet as the rest of his men killed themselves en masse clutching grenades to their chests. It was a horrifying conclusion fit to make the last Samurai Saigo Takamori proud. Now the Americans turned their gaze back east upon the isolated Kiska.

We left off with the fall of Attu to the Americans. Colonel Yamasaki’s doomed garrison made one last banzai charge into oblivion, leaving piles of their dead over the island. The Americans had suffered substantial casualties, making the battle of Attu the costliest ground battle as of now fought in the Pacific. In the words of General Bucker “[The Japanese proved to be a] tough fighter, with great physical endurance and fortitude. He was not afraid to die.” A number of lessons were learnt from the battle, including new landing techniques, and the necessity for rubberized, thoroughly waterproofed boots. The men on Attu had been given expensive, thick and insulated leather hunting boots, but these became absolutely useless once soaked in water. After Attu, improved winter kits emerged, and cases of hypothermia, frostbite or trench foot would become very rare among American soldiers even during bitterly cold campaigns in Italy and France. The Americans also learnt how masterful the Japanese were at creating concealed defensive works and at infiltration tactics.

The American forces got to see first hand how weather and terrain could pose the greatest threat to success. The Hourglass Division, owing to its initial desert training, was not prepared for Attu conditions, which demanded cold weather and mountain warfare expertise, clothing and equipment. In addition to being inadequately clothed, they failed to take care of themselves on the battlefield. The 7th Provisional Scout Battalion was only able to muster 40 men to walk after five days of action. In contrast, the 30-man detachment of Alaska Scouts, recruited because of their outdoors skills and experienced in Alaska conditions, lost one man killed in action, two wounded and one man with a slight case of trench foot. These type of lessons would prove very useful in future operations, to point out two, the future Italian and France campaigns which held some cold territories.

As the battle of Attu was coming to a close, Tokyo issued a directive on May 21st for the evacuation of Kiska’s 6000 man garrison led by Rear-Admiral Akiyama Monzo. The evacuation was going to be done using 13 I-class submarines from the1st submarine squadron of Rear-Admiral Kouda Takeo. But by early June Takeo would already realize the danger of using his force for such a task as one of his submarines would be sunk at Attu. There was a call to use surface ships if the weather permitted it and continuous calls to rush over to evacuate the Attu garrison, but the American naval blockade put an end to that idea and worse now it seemed the Northern Kuriles were in danger. Now Tokyo sought the deployment of fighters and anti-aircraft units to provide air defense and shore batteries to thwart an amphibious invasion of the Kuriles.

The Japanese had a daunting task laid before to them. In contrast to the relatively weak American naval forces deployed at the battle of the Komondorski islands, Admiral Kinkaids blockade and bombardment forces included the a trio of older battleships; the Mississippi, Idaho and New Mexico, a quintet of cruisers; Louisville, Portland, San Francisco, Santa Fe and Wichita and 9 destroyers. This powerful fleet showed up on July 19th under the joint command of Rear Admirals Robert C Giffen and Robert M Griffen, very close names there lol. Other destroyers and submarine chasers were operating in separate smaller commands within the region. Admiral Kawase Shiro took over IJN operations in the Aleutians and North Pacific following Hosogaya’s removal from command and thus found himself stuck with rescuing Kiska’s garrison from the teeth of a very powerful American blockade. Lacking the fleet strength to punch a hole in the blockade, thus Kawase had turned to submarines.

The 12 submarines under Takeo were Type C’s, heavily armed with torpedoes, deck guns and measured 358 feet long. Kawase’s first plan was to try and slip submarines through the blockade, but despite being large, the submarines could barely carry 150 men each, thus it would require 40 successful journeys to remove the entire garrison. With most American warships now equipped with sonar, this represented a hell of a risk, forcing Kawase to look towards other options. While the submarines would make runs as soon as possible, Kawase had to plan a surface evacuation.

The Japanese submarine evacuation of Kiska began on May 27th with the first submarine, the I-7 arriving at Kiska with food, ammunition and a radio beacon. She could only carry 60 passengers, which was reserved for the sick and wounded alongside 28 boxes of ashes for those who had died on the island and 4 tons of spent shell cartridges. A few more submarines managed to make the trek and evacuated a few hundred men from Kiska, but then the Japanese luck changed for the worse. The I-24 captained by Hanabusa Hiroshi, entered Kiska harbor in early June taking aboard 150 soldiers. On the night of the 10th, she was trying to slip away but as she was passing 40 miles north of Shemya Island, American sonar aboard the USS Larchmont, A pc-461 Class Submarine chaser pinged. Lt Wallace Cornell ordered is crew to depth charge the enemy submarine tossing 5 of them into the water. The Americans blasted the I-24 to the surface. Then Cornell ordered the Larchmont to put the pedal to the metal flooring the 450 ton sub chaser to ram the 2554 ton I-24. Larchmont rode up and over the submarine splashing into the sea on the far side. Upon seeing they failed to ram her, Cornell’s men began pounding the vulnerable I-24 with shells, before turning around to try ramming her again. This time the Larchmouth smashing into the I-24’s conning tower, fatally damaging the submarine. She sank stern-first into the black, frigid sea killing her 104 man crew and the 150 soldiers she was bearing.

Three days later, the destroyer USS Frazier sank the I-31 taking down her entire crew and the 150 soldiers she was evacuating. Out of 800 total men the submarine forces got off the island, 300 of them died to American attacks. As the summer would continue, combat and operational losses would see the destruction of 8 out of the original 13 submarines, leaving Takeo with 5. Kawase recognized the futility of the submarine operation and was forced to turn to his surface plan which would unfold in late july.

While all of this was going on, the Americans invaded the islands of Shemya and Agattu. Brigadier General John Copeland led elements of General Buckner’s 4th regiment and Colonel Talley’s 18th Engineers to land on Shemya during a tough storm. The Americans quickly surveyed the island to see if they could construct an airfield to accommodate a brand new experimental aircraft, the most iconic one of the Pacific War, the B-29 Superfortress heavy bomber. She had been in the works since 1938 and her objective would soon be long range bombing missions against the Japanese home islands. With their usual blinding speed, the American Engineers made the Attu air station operational by June 8th, then Shemya’s two weeks later. Alongside this the 11th air force would be reinforced with squadrons of the new PV-1 Ventura bomber, equipped with the latest airborne radar, which was capable of giving a clear picture of topographical contours that would be extremely useful while flying through the arctic weather and at night. Admiral Kinkaid would likewise shuffle his ships around to improve the blockade and General Butler’s airforce would spend most of June smashing Kiska with bombs. They would fly a total of 407 bombing sorties, though the Japanese arsenal of 70 anti-air batteries would give them a hell of a time doing so.

Completely uncontested the Americans would make unopposed landings on Semisopochmoi and the Rat Islands, covered only by PT boats. With these newly acquired airfields such as Attu and Shemya and the new aircraft on hand, the Americans were in sufficient range to bomb Paramushiro, Japan’s Gibraltar-like base guarded its northern approach. The first raid against Paramushiro would occur on July 10, with 6 B-24’s launching from Attu, but suddenly getting redirected to hit 4 Japanese wooden transports trying to breakthrough the naval blockade for Kiska. Although the American pilots successfully sunk 2 of them, they would not have enough fuel to continue on to hit Paramushiro. Another attempt would be made on Jul 18th seeing 6 B-24’s inflicting minimal damage upon Paramushiro, but it showed the Japanese their home soil was no longer safe from American bombers.

Tokyo was forced to reinforce the Kuriles and Hokkaido taking up valuable resources in men, guns, ships, aircraft and such from other places they were needed like the Solomons. Because of their large success, Buckner and Kinkaid saw significant budget increases and now the Joint Chiefs were seriously thinking about invading the Japanese home islands from the Aleutians. They went as far as to create plans with 1945 designated as the year they would invade Japan. Now we are shifting away from the north pacific to dive back into the situation of the second sino-japanese war.

The last time we were in China, the battle of West Hubei was raging on, with the 11th army of General Yokoyama invading south of the Yangtze River. Now Yokoyama would press on against the southwest portion of Yichang where the Chinese 11th division was defending Shipai Fortress; the 18th division was at Changyang and the 24th and 36th independent engineer battalions were at Yuyangkuan. The Chinese 11th division was led by General Hu Lien who held a considerably well defended fortress at Shipai, but also its approach which was the dangerous Xiling gorge. All combined, these defended the approach to Chongqing and Sichuan. Because of its vital importance, Commander Chen Cheng ordered Hu Lien to defend Shipai fortress to the death. By May 18th, the second phase of the IJA operation came to its conclusion, thus Yokoyama decided to concentrate his 13th division near Quanshuiwan, and his 3rd division backed by the Nozoe detachment near Shuangjingsi. This was in preparation for the third phase of the operation, a final drive against the Chinese defenses between Yichang and Yidu.

The IJA 13th Division began to move north while the 3rd and Nozoe detachment advanced south of Yichang to cross the Qingjiang river. The Japanese found many Chinese defensive positions along the way, but by this point the Chinese had been so brutally battered over the past month, they were still dazed and confused, thus easily brushed aside. The 18th army would manage to hinder the Japanese advance, forcing Yokoyama to redirect 3 battalions of the 39th division to join the offensive. By May 22nd, the 39th forded the Yangtze and joined up with the 3rd and Nozoe detachment to assault Changyang. As the Japanese forces approached Shipai Fortress from three directions, Commander Chen Cheng and General Sun Lianzhong tossed the 94th and 32nd armies to try and stop the Japanese advance at Yuyangkuan. Chen Cheng’s plan was to box in Yokoyama’s forward units at Yuyuangkuan, but instead the Japanese began dispersing and clashing with the Chinese 18th army at Changyang alongside Yuyangkuan by May 23rd. The defenders still jarred from the offensives were routing left right and center.

Fortunately the Chinese would manage to pull themselves together to reorganize a new defensive position to the right of the Shipai Fortress. Their last line of defense was to be at Muchiaochi, in front of Congqing and Sichuan, held by the 34th division. The Japanese were relentless as they continued their advance and by the end of May 26th they reached the defensive line. At this point Yokoyama had achieved his objectives as the vessels at Yichang could now advance towards Yueyang without facing resistance. He quickly ordered 53 steamers to navigate the river on the 27th, but then they were met with an expected enemy, the Major General Chennault's Flying Tigers.

During May of 1943, as we have seen, the Japanese launched a ground offensive targeting areas like DongDongting Lake and the Yangtze River region. The objectives were clear to the allies, the Japanese were seizing the colloquially called “rice bowl” region, right during harvest season. As the ground fighting intensified it became clear that the CHinese land forces desperately needed aerial support.

To counter the Japanese, the recently created 14th airforce as of march 10th 1943 led by Chennault and the Chinese 4th air group tossed P-40E’s and P-43’s to try and support the Chinese ground forces. On MAy 14th, Japanese reconnaissance covered Kweilin and Lingling, estimating the US order of battle was 24 P-40s, 8 B-24’s, 3 B-25’s, 1 P-38 and 1 P-43. It was also noted that the Chinese had advanced to Liangshan where their 4th air group was located.

The 4th air group went into action by May 19th with 8 P-40E’s, 4 P-43’s, alongside some A-29 Hudson bombers. The Chinese bombed the Japanese ground forces meeting some intense anti-aircraft gunfire back. Deputy group commander Xu Baoyun, flying a P-40E was shot down by Japanese anti-aircraft gunfire in the process. The next morning the Japanese bombed Liangshan by surprise giving the 4th air group no chance to retaliate. From May 19th-June 6th, the Chinese Air Forces would fly 336 fighter and 88 bomber sorties over the battle zone claiming to have shot down 31 Japanese aircraft. The 4th air group missing their chance to confront the Japanese on May 29th, when they fly from Liangshan to cover Chongqing due to a false alarm. While they were absent, 10 Japanese fighters strafed the field followed an hour later by 9 Japanese bombers with fighter escorts. On May 31st, 9 P-43’s escorted 5 A-29s to attack the ferry crossing between Yichang and Yidu, but in doing so they would miss the most intense action of the campaign.

On the same day Lt Colonel John Alison, an American ace alongside 2 USAAF wingmen led 7 P-40s from the 4th air group to escort 9 B-24 bombers over to Yichang. It was Alison’s last mission in China and the ace hoped to add to his record of kills. The allied airforce bombed and strafed Japanese ground forces but also got into dogfights with Japanese air forces. Alison’s aircraft was badly shot up by Captain Ohtsubo Yasuto the leader of the 1st Chutai squadron of the 33rd. Lt Tsang Hsu-Lan nicknamed “Bulldog” took his No.2304 P-40 to swing behind Ohtsubo as he was firing upon Alison and managed to shot his aircraft down, saving Alison’s life. Tsang was awarded a American Silver Star and the highest medals China could offer.

On June 6th the 14 K-43’s and 8 light bombers attacked Liangshan. 13 Chinese P-40’s led by COlonel Li Hsiang-Yang were returning from a mission to Liangshan and were landing as the Japanese approached. Captain Chow Chin-kai, commander of the 23rd squadron and a veteran of many years of combat, directed the ground crews to take defensive measures and then apparently climbed into a P-66 Vanguard. Without time to adjust his parachute, check his fuel nor even buckle his seatbelt he gunned the engine. While the Japanese strafed the field, Chow went directly for the bombers, claiming 3 destroyed. Chow received the Blue Sky White Sun award personally from Chiang Kai-shek for this action. Yet despite his heroism, 12 P-40’s and a fleet trainer were destroyed on the grounds of Liangshan.

What became known as the Rice Bowl Campaign took a heavy toll on the CAF. In addition to their loses in combat and on the ground suffered most by P-40’s, many other aircraft suffered from operational damage. After the campaign the operational CAF aircrafts would number 6 out of 7 A -29s, 5 out of 10 SB-3s, 3 out of 5 P-40E’s, 6 out of 9 P-43s and 39 out of 46 P-66’s. The 14th airforce played a small role overall in the Rice Bowl campaign and thus their losses were quite minimal.

Meanwhile at the Shipai Fortress, Hu Lien faced direct attacks from the IJA 68th regiment on May 28th. Told to fight to the death, the defenders managed to repel each enemy assault inflicting significant casualties upon the invaders. Hu Lien would personally led the troops at all times in their efforts to dig in and build fortifications. To the right flank the 3rd and 39th divisions charged against new positions manned by exhausted soldiers of the 18th army, who resisted as much as they could. However they were simply no match for the full might of two Japanese divisions and soon two Chinese companies were annihilated as the rest pulled back. General Luo Guangwen of the 18th Chinese division boldly decided to counterattack, launching a rain of grenade and mortar fire over the 3rd and 39ht divisions halting their advance. Although aided by artillery and aerial bombardment, the Japanese were still pressing hard against the defenders.

The Chinese 94th and 32nd armies then arrived to the scene, and the 94th army went to work successfully blocking the advance of the 13th division near Dayanxiang. This forced the Japanese to cross the dangerous Tianzhu Mountain which would claim much of their equipment. Further down the road, the 13th division was also ambushed by concealed forces of the 32nd army, managing to inflict hundreds of casualties upon them. Because of the increased losses, Yokoyama ordered the Noji detachment at Yichang to cross the Yangtze to assault Shipai Fortress frontally in a last ditch effort to break Hu Lien’s lines. On the 29th, the Noji detachment launched its attack, breaking through Hu Lien’s line at Qiuqianping, inflicting sever casualties upon the 11th division which was forced to retreat towards the bay.

By the end of the 29th, the 18th Army’s other units were also withdrawing, leaving Hu Lien alone to face the brunt of the enemies advance. But by the point the Japanese had suffered tremendous losses and the steamers at Yichang had already arrived to Shishou, thus Yokoyama feared he was overstretched and that his forces might get trapped by Chinese units moving to Changyang. Thus not wanting to see things fall apart, Yokoyama ordered an end to the operation on the 29th and preparing his forces for a withdrawal. But the next day the 13th division decided to press an attack upon Muchiaochi, not knowing the 32nd Army had set up another ambush for them there. The Chinese unleashed artillery on the Japanese inflicting more casualties on the already battered division. Meanwhile the isolated 11th division was repealed the combined attacks of the 3rd and 39th divisions, repelling 10 consecutive attacks throughout the day, leaving the bay area full of dead Japanese. on the 31th the Japanese began their withdrawal as more and more Chinese reinforcements were arriving for a massive counterattack. While the 3rd and 39th divisions managed to avoid battles as they crossed the Yangtze at Yichang, the battered 13th division was heading towards Yidu and was trapped by the 32nd army at Changyang by June 3rd. The 13th division would manage to break free and flee towards Gongan, but the division which was earmarked to depart for the Pacific, lost so many men they would be forced to remain in China. Yokoyama was forced to send the 17th independent mixed brigade who had already managed to withdraw to Shishou to rescue the 13th division. They arrived to Gongan on June 5th, and fight a long series of battles to help the remnants of the 13th division to limp back to Shishou by June 8th.

With the Japanese operation concluded, Commander Chen Cheng and General Sun Lianzhong would successfully recapture most of the lost territory and begin rebuilding defensive lines as they did. The Japanese claimed to have suffered 3500 casualties with 771 dead and 2746 wounded, though it should be noted other sources claim their losses were considerably higher, as the 13th division was practically destroyed, the 17th mixed brigade, 3rd and 39th divisions were also severely damaged indicating losses possibly in the tens of thousands. The losses were so grave, the Japanese would not be able to start another offensive in China until the end of the year. Thus the gateway to Chongqing and Sichuan were held, paraded as a grand victory by the Chinese. As I indicated in a previous episode however, Historians such as Barbara W. Tuchman suggest "the Japanese withdrew without pursuit from what appeared to have been a training and foraging offensive to collect rice and river shipping." In other words, the Rice Bowl campaign as it became known, basically saw the Japanese stealing the bowl of rice for 1943.

Now we are not done just yet, there is some action going on in the Solomons. The Japanese had just conducted Operation I-Go and despite their pilots extremely overexaggerated claims, it truly was a lackluster offensive. Alongside this the legendary Admiral, Isoroku Yamamoto had been assassinated on April 18th, shattering Japanese morale. Nonetheless the show had to go on as they say and now Admiral Kusaka would need to reorganize, repair and reinforce his air forces in preparation for the next expected American offensive in the Solomons. Kusaka was reinforced with the 12th Air Fleet; consisting of the 24th and 27th Air Flotillas. The 11th Air Fleet meanwhile, would be reinforced with the 25th Air Flotilla holding 60 Zeros, 10 J1N1s and 50 G4Ms. Kusaka’s 26th Air Flotilla, who should have been relieved, would be forced to fight on for the duration of the campaign against Rabaul; but the 21st Air Flotilla would be sent to Saipan for rehabilitation.

Now since the evacuation of Guadalcanal, the Japanese had created a new defensive line with Rekata bay being the hub for the Santa Isabel defense line and Munda the hub for New Georgia with its forward post at Wickham anchorage. This meant forward bases needed to be reinforced, so Santa Isabel received the 7th Combined Special Naval Landing Force of Rear-Admiral Katsuno Minoru, consisting of the Kure 7th SNLF and the 3rd Battalion, 23rd Regiment. New Georgia received the 2nd battalion, 229th regiment of Captain Iwabuchi Sanji, the 41st antiaircraft battalion, the 4th, 10th and 22nd construction units who went to Munda, the 1st battalion, 229th regiment and 1st machine-gun company who would go to Wickham anchorage. Kusaka envisioned the main defense force to be Rear Admiral Ota Minoru’s 8th combined SNLF. This consisted of the Kure 6th and Yokosuka 7th who had recently been converted into heavy artillery units originally set to for hitting the Americans on Guadalcanal. Other support, rifle companies and heavy weapons compies made up the rest of the SNLF force. By late January Ota’s force began its movement to New Georgia, arrived to Munda by the end of the month, though a large air strike rocked them on January 29th sinking 75 barge loads of valuable cargo. The Japanese sent various forces to occupy Vila and Rekata Bay in January where bases would be developed.

On February 27, Choiseul coast watchers spotted Kirikawa Maru carrying two 14cm guns, four 8cm dual-purpose guns, 600 tons of ammunition and supplies, and SNLF personnel as the ship and its two escorts cleared the Shortlands. A PBY and the coast watchers reported their course, and a COMAIRSOLS strike force of fourteen SBDs, with an escort of twenty-four fighters, caught them three miles off the northeast tip of Vella Lavella. The escort took on the thirteen Zeros and two F1Ms flying cover, and in the fight that followed each side lost two aircraft. The SBDs went about their business with deadly effect; a surviving Japanese medical officer later wrote that the bombs were exploding in the ship like a fireworks exhibition at Ryōgoku Bridge in Tokyo. This would force the Japanese to yet again rely on the good ol Tokyo express much to their dismay. Alongside that the battle of Blackett strait on March 6th forced the Japanese to avoid the Kula gulf and instead op for the Fergusson passage. Through march to May the Japanese would suffer only one loss, the sea truck Gisho Maru, thus the new route seemed to be successful. However with all of the shuffling by both sides it seemed evident, a new bloody campaign was about to be unleashed in the Solomons.

The Japanese struck hard into the heart of China’s Rice Bowl Region. Both the Chinese and Japanese lost significant amounts of men to the bloody campaign, Chongqing and Sichuan were safe, but in the end the Japanese had secured their objectives.
