Last time we spoke about the allied drive to Munda and General Sasaki’s major counter offensive. General Wing began the drive upon Munda Point, but General Sasaki predicted many of the routes the Americans would take and ordered his forces to create tedious roadblocks and defensive positions to foil their advances. The allied progress was brutally slow, despite having the enormous advantage in artillery, naval and aerial bombardment support. The Japanese pillboxes were proving to be devastating to the allied infantry, requiring tanks to be brought over to New Georgia. When things began to halt, suddenly General Sasaki performed a counter offensive seeing a daring attack directed at the headquarters of the 43rd division. The attack nearly broke the lines of communications, but luckily the Fijian commandos outperformed the japanese at their own game of night fighting. Lastly the IJN suffered terrible losses to allied aircraft collapsing their reinforcement efforts.

The battles in New Guinea and New Georgia were particularly bloody, in all honesty things had begun to really escalate when you look at it from a numerical point of view. Over on Green Hell, General Savige had just seized Mubo, the Pimple, Green Hill and Observation hill taking them out of Japanese hands. The Japanese had withdrawn to Komiatum while simultaneously trying to defend the Bobdubi ridge area against Brigadier Hammer’s 15th brigade. General Savige, still unaware Salamaua was not the main target and in fact was being used as a deception to cover for Lae, continued his offensive, hoping to drive the enemy north of the Francisco River.
Over on the other side, General Nakano’s 1st battalion of the 80th regiment had managed to push Companies B and A off their ambush position on the Bench Cut Track. They were forced to withdraw towards Gwaibolom by July 10th. Meanwhile to the south Major Warfe launched an attack along Goodview junction. Captain Wally Meares of C platoon marched up Stephens Track while Captain John Winterflood’s B platoon took Walpoles track. Lt Hugh Egan created a blocking position using just 7 men around 800 meters south of Goodview Junction. The platoons went to work advancing down the steep ridges dislodging Japanese from outposts. Captain Meares platoon were continuing along the Stephens track when they suddenly encountered strong resistance from some Japanese who took a position along the Tambu Saddle which is at a junction between Stephens track and the Mule track. After engaging the Japanese, the platoon was forced to bypass them moving along the Mule track towards the Komiatum track where they ran into more Japanese. Meares men killed 13 Japanese on the Mule track before deciding to withdraw back to the Stephens track and dug in.
The Japanese had surprised Warfe’s men. The forces they were running into were mainly the 1st and 2nd companies of the 66th battalion along with Araki’s HQ staff who had been on the run from Mubo to Komiatum. The Japanese tried to press on with a counter attack aimed at Winterflood’s B platoon. The Japanese tossed mortar and machine gun fire, but received terrible losses to the commandos, forced to pull back up Walpole track. The next day Warfe ordered Winterflood’s platoon to make a frontal assault, but quickly found themselves pinned down by machine gun fire and during the night received a heavy counter attack that forced them to dig in. The Japanese continued to block the way, covering their withdrawal further east, but all the mayhem prompted General Savige to relieve the commandos by tossing up companies C and B of the 2/5th who adopted the name Bennett force as they were led by Captain Cam Bennett. The rest of the 2/5th marched up the Buigap.
Meanwhile General Herring was dealing with a supply issue for the 3rd Australian division. The 3rd division was too far from the coast and thus had been relying on supply via airdrops, which we have seen during this series to not be particularly accurate and quite inadequate. The supply problems mounted more when the decision was made to target Lae as such a campaign required building up reserve dumps. Warfe’s men were critically low on supplies; the 58/59th had nearly used up all the supplies they received, being brought up via the Missim Track and from airdrops. Getting further and further away from the source of supplies and with declining carrier capacity, Warfe’s men were reaching starvation point. Further back, Companies A and C of the 2/6th battalion got drafted the job of moving the supplies from Mubo to Buigap creek. General Herring considered it extremely difficult, but not impossible to maintain further units in the Salamaua area, if they were closer to the coasts. To solve the problem General Herring designated Tambu Bay as a new coastal base for supplies and it would also help as an artillery position.
And thus, the 3rd battalion, 162nd regiment of Major Archibald Roosevelt landed at Nassau Bay back on July 12th commencing with their coastal advance. They were accompanied by Brigadier General Ralph Coane’s artillery that had landed prior to them. Yet their advance would begin in an extremely confused and chaotic manner. The question of command was at the core of the issue, General Fuller had decided to separate units such as Archibald Roosevelts from the MacKechnie Force, and thus they were now placed under the command of the Coane Force. General Herring was forced to intervene, placing the Coane Force under General Savige. At the same time, Colonel MacKechnie was relieved of his command because Fuller felt that he had favored the Australians over the Americans. To dig depper into this mess, what occurred was General Savige and Colonel MacKechnie were both unaware that two-thirds of the 162nd regiment had been allocated to the Coane Force when General Herring sent the a confusing message to try and clarify things “all units MACK force are under operational control of 3 Aust Div”. Troubles began at Moten ordered Major Roosevelt to advance north, but Roosevelt had also been told by General Fuller that he was not under Australian command. Thus Roosevelt bluntly replied to Moten “For your information I obey no orders except those from my immediate superior”. Then MacKechnie tried to smooth things over with Moten when he was informed of Fuller’s position. He apologized for Roosevelt’s message, and tried to speak about how great all the Australian/American cooperation was going. Fuller and Herring then tried to clarify the situation by placing the Coane Force under General Savige, but Fuller also decided to dismiss MacKechnie, mostly because he had relinquished command of his men to the Australians and thus had failed to protect American interests. As I say on my personnel channel, often when talking about China’s Warlords in the 1920’s, this is some kindergarten bullshit.
Back to the action at hand, the Coane Force was being aided by a Papuan company who were scouting ahead of the Americans. They managed to confirm that Tambu Bay and the Dot Inlet were occupied and fortified by the Japanese. A platoon of the 5th Sasebo SNLF and the 3rd battalion, 66th regiment were holding a position on Tambu Bay while the remnants of the 3rd battalion, 102nd regiment were on a ridge overlooking the bay, which would later be named Roosevelt Ridge. On July 18th, Roosevelt led the troops with Companies L and I taking the lead, guided by two Papuan platoons. L Company with a Papuan company advanced along an inland track while K Company likewise did so along the coast. K Companies’s Papuan guides hit a Japanese outpost south of Boisi on July 18th. On the morning of the 20th, the Papuan platoon managed to kill four Japanese before K Company helped destroy the outpost. By the 20th they seized Boisi and Roosevelt with the others approached the Tambu bay. Roosevelt had Coane’s artillery support, they brought up four 25 pounders of the 2/6th Australian field regiment originally placed at Nassau Bay along with 2 batteries of the 218th American field artillery battalion, 8 75mm guns from north Salus, a battery of the 205th American field artillery battalion and 4 105mm guns. Under the cover the artillery they attacked the enemy, but they were met with heavy mortar fire coming from Roosevelt Ridge. Roosevelt Ridge extended westwards from the sea for nearly 2000 yards, forming kind of bulwark that shielded the northern end of Tambu Bay. Thus Tambu Bay could not be secured unless the ridge was taken first. The Australian broadcasting commission correspondent, Peter Hemery described the ridge like this “a piece of old style razer blade jutting into the sea”. According to some Japanese sources they had this to say of it “The area around Boisi had a lay of land most suitable to the arrest of the enemy advancing northward along the coast”
General Nakano had also decided to reinforce the ridge with 250 men of the 1st battalion, 115th regiment, but of course this came at the coast of Salamaua’s defense. By this point the bulk of the 102nd regiment was at the Malolo-buang coastal area and the bulk of the 115th regiment, the 2nd Maizuru SNLF, two companies of the 5th Sasebo SNLF and the 14th field artillery regiment were at Salamaua, around 150 men in total. On the other side, after the fall of Mubo Brigadier Moten had the men advance north. The Bennet Force took over Goodview Junction; Companies A and D of the 2/5th advanced to Mount Tambu. Mount Tambu was the highest feature along the route between Mubo and Salamaua. It consisted of a series of razorback ridges covered in dense jungle, ideal for camouflage pillboxes. Its area was defended by roughly 700 Japanese from the 2nd and 3rd battalions of the 66th regiment led by Lt Colonel Fukuzo Kimura and Major Sakai Sugiyama. On July 16th, Captain Mick Walter led 60 men of Company A up the steep track leading to the south crest of Mount Tambu. Walter led the men to storm the two forward knolls, taking the Japanese by complete surprise. The two knolls were captured, but during the night the Japanese counterattacked in force. The Japanese crawled up the knolls through some heavy undergrowth before they unleashed mortars and mountain gun fire. Walters men however had captured some Japanese pillboxes upon the two knolls and thus the turn tables. 8 counterattacks were tossed at Walters men, each repulsed with heavy losses, around 39 casualties for the Australians and 350 for the Japanese. The following day, D company came up to help the Australian defenders, bringing much needed mortars. They dug in on a knoll around 300 yards back on the track. Alongside D company also came much needed supplies and an additional platoon to reinforce his men who he deployed on his western flank.
On July 18th, Walter ordered an advance going northwest in an attempt to secure the southern portion of Mount Tambu. The advance was spearheaded by Lance Corporal Jackson who alongside his comrades tossed grenades into a Japanese pillbox. Jackson then stormed inside killing 3 Japanese with this Tommy gun. Alongside Jackson, mortar and mountain gun fire aided Walters men to gain 80 additional yards, securing the southern portion of Mount Tambu. They could advance no further however as it became much more difficult from this position as the Japanese basically were encircling them upon razer back ridge to their north. Walter would write later on “we dug in on the new ground and shortened our perimeter to the narrowing plateau”. For this action the Australians paid with 6 lives, 13 wounded while the Japanese lost 82. At this point Walter had D company with one of his platoon holding the western flank; A company held the northern knoll and two platoons from D company held the eastern knolls.
The Japanese had been devastated, losing hundreds of men and allied artillery was becoming a nightmare. Captain Newman’s C Company of the 162nd battalion had come to a junction of the Buigap and Bui Eo. From there a reconnaissance patrol found suitable artillery positions northwest of the junction. With the help of native carriers and 80 men of the 2/6th battalion, two guns were hauled over the Buigap track and by July 17th another 4 guns of the American 218th battalion were hauled up from the southern arm of the Bitoi river to Green Hill. From these positions the allies could smash multiple Japanese defensive positions. General Nakano realized Mount Tambu was an essential component of General Muroya’s defensive line so he sent the remainder of the 3rd battalion, 66th regiment to reinforce Colonel Araki’s men.
Then during the early hours of July 19th a large earth tremor startled the Australian defenders. It was the prelude to an assault led by Captain Kunizo Hatsugai’s 9th company of the 66th regiment. They had crept up silently managing to get behind the southern knolls then suddenly charged up under the cover of darkness. But the defenders had their guard up and were not taken by surprise. A Bren gunner managed to knock out one of the Japanese raiders machine guns with a lucky hit in the dark. As the Japanese scrambled to try and recover it they were met with fire causing severe casualties. The Japanese surprise attack was a failure, forcing them to withdraw by first light, leaving 21 dead across the knoll. While this raid was occuring, Walters men were also repelling a series of attacks against the Northern Knoll. During these attacks, Walter was injured. Luckily for Walter and his company, they were relieved on the 19th by D Company. Another American unit, C Company of the 1st battalion, 162nd regiment led by Captain Delmar Newman also arrived to take up a position on the southern knolls. Until july 23rd, the Australians limited their actions to patrols. On the 20th, Bennet led a patrol making contact with a strong Japanese position on the Walpole track; Another company led by Morse found a Japanese position in the Goodview area dug within 100 yards of their own. Meanwhile the Japanese also limited their actions to a few patrols proding Mount Tambu for weaknesses.
On July 23rd Moten ordered the 2/5th battalion to attack the remaining Japanese positions on the Tambu Knoll, but it was the most heavily fortified yet. Basically it was like a castle keep, complete with a ravine for a moat, near vertical walls and deep tunnels going through the knoll. Mount Tambu’s peak held 10 log reinforce bunkers connected by the tunnels which could shelter half a battalion or so. They also had a chain of weapon pits set up on lower ledges. Later on when investigating the entire system, the allies found weapon pits to be around 4 logs thick, interconnected by crawl trenches. Many of these weapon puts had been carefully sited within the roots of large trees, making them impervious to allied artillery fire. The tunnel entrances were dug into the side of the peak directly behind the defensive positions, allowing the defenders to storm out from their shelters underground within seconds. It was these kind of ingenious defensive works that would be built upon later on in the war to create absolute nightmares for the allies.
Moten had not carried out a thorough reconnaissance of the Japanese positions prior to ordering the attack and thus many of his subordinates elected to make a frontal assault instead of encircling them. D company took the center for the frontal attack while to the left were the 16th platoon led by Sergeant Alvin ‘Hungry’ Williams and the 18th platoon led by Lt Bernard Leonads; and A company advanced along a Caffins track heading for the western flank of Mount Tambu to try and cut off the main Japanese supply route going back to Komiatum. 15 minutes before they charged, Australian and American artillery and mortars fired upon Mount Tambu. Two Australian mountain guns fired 90 rounds while the 4 75mm American guns fired 60 per gun from Green hill. D company began their attack around midday, trying to drive a wedge between two lines of pillboxes. Corporal John Smith laid cover fire as Captain Lin Cameron crept forward, getting within 15 yards of the pill boxes on the left side of the track. Cameron counted around 7 pill boxes in two lines of defense going across both sides of the track. The steep slopes on both sides gave little venues of approach, allowing around just a platoon at a time. There was also sharpened bamboo pickets on the left flank, leading Cameron to believe that an attack was expected there.
The Japanese knowingly let two platoons reach their line of forward pillboxes before unleashing hell upon them. The casualties were terrible. As Cameron recounted, “we were within 20 meters of the enemy bunkers before all hell let loose”. One of the men in the forward sections was killed outright, Cameron was wounded, his right elbow was shattered by a machine gun bullet. As he saw his men hesitate, he screamed out “forward! Get stuck into them!” With his right arm now useless and his eyesight dimming, Cameron handed command over to Lt Martin. Despite the horror, the Australians pressed on. Corporal Carey led his depleted platoon forward in a great dash and swept the outer ring of the Japanese pillboxes. On his left were Leonards men who stormed two pillboxes before heavy enfilade fire pinned them down. Then the 17th platoon led by Corporal John Smith charged up Mount Tambu from behind with their bayonets fixed. Smith screamed out “follow me!” as he charged. 3 other men out of the 11 managed to keep up with Smith, but soon Japanese grenades began to rain down on them. The grenades caught them just as they passed a third line of pillboxes. Smith was hit, but he kept charging and when he reached the peak of Mount Tambu with his back to the enemy he screamed “come on boys! come on boys!”. Without additional support and with no indication A company were making progress over on the left flank, the 4 men on the peak were forced to withdraw. The gallant Smith had to be dragged down and would die from severe wounds two days later. Smith was decorated for bravery in Syria in 1941, when he cleared out 3 machine gun nests at a roadblock and despite being wounded during the battle of Wau he still had gas left in the tank for some more.
Scouts had made their way towards the Tambu saddle track and spotted Japanese soldiers, around 125 of them a full company or so. The scouts quickly realized they were outnumbered, thus when the artillery began to open up and Walter’s company moved in for the attack across the saddle, no sooner then they started the enemy halted them in their tracks. Walter had no choice but to withdraw around 500 yards south east as the Japanese were too strong. Walter’s inability to make progress in the west ultimately ruined the entire attack. Despite the defeat, Companies A and D had done very well against such a heavily fortified position.
Meanwhile, Warfe and his men were marching when they discovered Ambush Knoll had come back under the hands of some Japanese from the 2nd battalion, 66th regiment. On July 15th, Warfes commandos launched an attack, with C Platoon performing a frontal assault along the narrow ridge top track. There were 16 men in the attack and they found themselves face to face with well dug in Japanese. The Japanese were behind a bamboo barricade with some pillboxes scattered about. The platoon got within 50 feet of the main barricade, but the Japanese fire was too much and casualties were mounting quickly. Meanwhile B Platoon was maneuvering around the Japanese eastern flank. At 5:30 B Platoon began attacking the eastern side of the knoll. The men got behind an enemy pillbox covering the track from Orodubi, but the Japanese quickly saw the Australians and began tossing grenades at them. Despite the resistance, B Platoon managed cut off the Japanese supply line to Ambush Knoll. With their supply lines cut the Japanese were forced to withdraw
With Ambush Knoll back under allied control, Brigadier Hammer ordered A company of the 58/59th battalion to depart Gwaibolom and attack Orodubi from its southern flank. Even with the help of the 58/59th company, the commando’s yet again failed to dislodge the Japanese. On the night of July 19th, fresh troops of the 1st company, 80th battalion used the light of the full moon to come up the ridge. This became a staging point for them to attack Ambush Knoll, seeing artillery fire beginning in the morning to support their attack. Warfe’s commandos were manning the trenches on Ambush Knoll, turning the tables on the Japanese and inflicting heavy casualties upon them. The Japanese were forced to retreat. The next day Warfe reinforced Ambush Knoll with two Vickers guns, which gave the Japanese a nasty surprise when they attacked again. On the 20th, the Japanese opened fire with mortars and artillery before charging the ridge. They managed to get as far as to cut the Australian lines of communication, but were ultimately repealed once again. Over 14 consecutive attacks would be made on the 20th, and even more on the 21st, but it all came to nothing, Warfe’s commandos held their ground. Facing such pressure from the Japanese, Hammer still felt the greater weight of their attention was directed at Bobdubi and not towards Tambu, believing it to all be a consequence of Moton’s lack of progress. General Savige decided to order Motens 2/6th battalion to take responsibility over Bobdubi ridge. The 2/6th then came across the Japanese rear near the slopes of Ambush Knoll and began harassing them. On the 22nd the Japanese tried yet again to attack Ambush Knoll, but were beaten back firmly, forcing them to finally withdraw to Sugarcane Ridge. By July 23rd, Warfes’ exhausted commandos earned a relief by the 2/6th and were sent to relieve A company at Gwaibolom, while A company advanced north. The 2/6th likewise would advance north. But now we are moving away from the troubles of New Guinea and heading back up north to the frigid Aleutians.
After the successful seizure of Attu, now Admiral Kinkaid and General Buckner needed to plan the invasion of Kiska. Kiska was the last Japanese bulwark in the Aleutians and held an incredible underground city. There were miles of tunnels, buried ammunition dumps, barracks, 3 hospitals, dental clinics, mess halls, machine shops, warehouses, photo labs, telephone rooms, all shoved and shored with wood. Ventilation pipes connected the maze of caves and tunnels, with Japanese troops wearing great fur lined coats busy at work. The Americans had experienced hell, on Attu, over 2872 Japanese had been killed or committed suicide, just 28 men were captured and it cost 549 american lives, 1148 wounded and nearly another 2000 ill or battered by harsh climate. The American leadership expected Kiska to be another hellscape and did not want to come at it lightly. The 7th division led by Brigadier General Archibald Arnolrd, Buckner’s 4th regiment, the 87th Mountain infantry regiment, the 13th Canadian Brigade, consisting of the 6th Canadian division led by Major General George Pearkes, the Canadian Fusiliers regiment, the 1st battalion of Winnipeg grenadiers, the Rocky Mountain rangers regiment and e Regiment de Hull along with the 1st Special Service Force led by Colonel Robert Frederick were to be part of the invasion of Kiska, codenamed Operation Cottage. Unfortunately, the actual invasion will not be happening in this episode, you will actually have to wait weeks for that one, but I just so happened to have recently done a podcast with a Canadian Military Historian named Brad St.Croix from the Youtube channel OTD Military History, the same gentleman who I interviewed for this series about the battle of Hong Kong. The podcast we recently did was on the Canadian experience of the Pacific War and the battle of Kiska is 1/3rd of it, so if you are, impatient and want to learn some neat stuff about how Canadians had to change their entire military organization and use American equipment for the battle of Kiska, check out my Youtube channel, the Pacific War channel for the full episode.
Now the last time we spoke about Kiska, the Japanese were forced to perform a bit of a miracle to evacuate their boys. After Attu had fallen, Rear Admiral Akiyama Monzo alongside 6000 men were ordered to evacuate Kiska. To try and do this, the Japanese began by sending 13 I-class submarines of the 1st submarine squadron of Rear Admiral Kouda Takeo. Despite these Type C submarines being enormous in size, they could only carry around 150 men per trip, thus it would have took 40 successful journey’s to evacuate the entire Kiska garrison. With the US Navy fully decked out with sonar, this was not going to be a walk in the park. The efforts had begun on May 27th and by July, the submarines had managed to get 800 men safely back to Japan, but lost 300 due to american attacks.
Meanwhile Admiral Giffen had a considerable armada to work with consisting of 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. He was ordered to bombard Kiska who already had been smashed with aerial attacks all throughout June and early July. On July 6th, Giffen steamed towards Kiska with 4 cruisers and 4 destroyers and bombarded the island for 22nd minutes causing a handful of casualties. It was not all that impressive, but it convinced Admiral Kawase that the Americans were about to invade Kiska at any moment.Admiral Kawase Shiro realized the futility of the submarine effort and was forced to come up with a new plan. Kawase came up with a bold plan, he was going to wait for a night when a thick fog was occurring and would take a surface fleet to sneak over into the Aleutians to assault enemy warships and evacuate all the remaining men on Kiska in a single go. To be blunt, it was a dumb idea. The American warships were equipped with radar that would pick up any surface ship with ease despite any type of fog, but what was about to occur can only be described as spectacular and bizarre.
Rear Admiral Kimura, the victor of the battle of the bismarck sea, would lead the force and he had at his disposal Destroyer Squadron 1: consisting of Yugumo, Kazagumo, Asagumo, Akigumo, Usugumo, Hibiki (one of my favorite whiskeys), Shimakaze, Samidare, Naganami, Wakaba, Hatsushimo and light cruisers Abukuma and Kiso. In close support of these there was also a covering force consisting of heavy cruisers Nachi, Maya, light cruiser Tama and destroyers Nokaze and Namikaze. The large convoy force departed from Paramushiro on July 7th with Takeo’s 1st submarine squadron performing reconnaissance. The covering force departed Paramushiro on July 10th and by July 12th the fleet was around 500 miles south of Kiska. When they took up this assembly position, the sailors were in despair to see the fog was quite low. While it did not matter for warships with radar, Kimura knew full well what allied aircraft could do to his forces if they were not better concealed. Thus he elected to wait until the fog reappaered to cover his force. But the weather did not change, the skies remained clear forcing him to head back on July 15th. Meanwhile on Kiska, Rear Admiral Monzo was frantically ordering his troops to lay out a road from the underground base to the harbor piers to help facilitate the impending evacuation. All of the Japanese on Kiska felt an impending doom placed upon them. If the Americans landed first, it was all but over for them.
Luckily, Japanese weather stations reported a dense fog would emerge over Kiska by July 25th, and unlike here in Montreal Canada, I guess these weather reporters are accurate. Kimura once again departed Paramushiro on July 22nd, accompanied by Admiral Kawase aboard cruiser Tama. Yet a few days prior, on July 19th, Admiral Kinkaid had ordered Admiral Giffen to bombard Kiska again. This time Giffen took a two pronged naval attack force consisting of battleships Mississippi and Idaho, cruisers Portland, Wichita, San Francisco, Louisville, Santa Fe and destroyers Abner Read, Farragut, Monaghan, Perry, Aylwin, Bache, Hughes, Morris and Mustin. Giffen’s force reached Kiska on July 22nd and his ships smashed the island with 424000 lbs of high explosive shells. Just an hour later, a PBY suddenly detached with her radar 7 radar pips southwest of Attu. The PBY maintained contact for around 6 hours before low fuel forced her to return to base. These radar pips alarmed Admiral Kinkaid which was being reported in conjunction with a massive increase in Japanese radio activity on Kiska. Kinkaid believed a major Japanese fleet had just entered Aleutian waters, most likely a reinforcement convoy. Kinkaid immediately ordered Rear Admirals Giffen and Griffin to intercept the suspected enemy. However, by doing this he had also done something extremely favorable for the Japanese, he had left Kiska Harbor open and unguarded. Kinkaid dispatched a quartet of PT boats to try and provide a makeshift blockade, but the terrible weather forced the smaller vessels to return to port as trying to dash over to Kiska would probably see them all sunk.
While this was occurring, Kimura’s ships were traveling through the dense fog separately. The fog prevented the Americans from intercepting them initially, and having failed to make contact with the enemy, Kinkaid became nervous the Japanese might escape the blockade and ordered the force to return to Kiska at maximum speed on July 25th. The American ships dutifully turned back while Kinkaid sent the Oiler Pecos out to meet them for refueling. By dusk of the 25th, the American ships were around 90 miles from Kiska, when the fog had all but disappeared showing a cloudless sky. Kimura’s vessels seeing their fog betray them, all reunited as a single force, now bearing 400 miles south of the American warships. At precisely 12:43am on July 26th the American warships picked up 7 strong radar pips around 15 miles northeast. It was Mississippi’s SG radar that first picked them up, the American destroyers were actually unable to detect any pips on their radar due to the curvature of the ocean's surface at such a distance. The New Mexico, Portland, San Francisco and Wichita began picking up the same radar pips. The radar pips zigzagged across the sea surface, changing direction in much the same way ships attempting to evade detection might. The ships were being detected all at different angles, verifying to the Americans there were physical presences of some kind occupying definite points in space. On top of this, the immobile radar signature of Kiska’s volcano at a range of 78 miles appeared clearly the entire time, verifying the validity of the pips moving with a fixed landmark. The radar pips converged 22,000 yards ahead of the Americans forcing them to spring into action.
Admiral Giffen called for the entire fleet to turn left to intercept the pips on their southerly heading and in the hopes of foiling a possible torpedo attack. All of the American ships turned their guns to fire salvo’s into the night. Great flame lances stabbed into the darkness as destroyers launched volleys of torpedoes and radar plotters frantically calculated salvo corrections. For 67 minutes the Americans tracked the 7 radar pips firing wildly at them. At 1:30am the Mississippi’s log recorded zig-zags and a 20 degree course change, but not a single sailor saw an enemy ship. Cruisers San Francisco and Santa Fe registered shell splashes, but never an enemy target. 75 miles over on Kiska, the Japanese were watching a spectacle. From their point of view it was like a night-time light show over the horizon. By 2:22am the radar pips thinned, faded and vanished completely. During the morning surface ships and aircraft fanned out looking for wreckage, ships, floating papers, oil slick, anything to indicate something was even out there! The American warships reported no return fire, it was as if they faced ghosts. With a lack of fuel and ammunition, the US ships began refueling on the 28th and resumed their blockade of Kiska.
What famously has become known as the battle of the Pips left the US Navy with a mystery that remains unsolved to this very day. The radar equipment was operating at times where there was a cloudless night with no fog, zero reasons for false radar echoes. An Aleutian crab fishing captain named Captain George Fulton may have solved the mystery in 1991 when he managed to duplicate the radar signatures observed during the battle by using his radar on a natural phenomenon common to the area. He presented his findings to the Alaska War Symposium in 1993 in a letter “I […] duplicated the Battle of the Pips using color radar. Sure enough there were blips on the tube and their density changed from red to orange to yellow and finally to black, providing an exact replication of the Battle of the Pips. What you described fits exactly the […] pattern of dense flocks of mutton birds or dusky shearwaters […] As mutton birds fly they veer left and right. This accounts for the zigzagging that was reported on the radar logs” Captain Fulton further went on to say how these huge flocks continue until they see large schools of fish, such as pollack. When the birds see them they begin landing on the sea surface then dive for their prey. This maneuver causes them to vanish from radar screens entirely. In the 1990s Aleutian fishing crews use this trait to locate large concentration of pollack, identifying the blips by their zigzagging motion and cast their nets accordingly. Were the Japanese saved by shearwater birds?
Another answer came from the US Navy who officially stated that atmospheric echoes, a sort of phenomena caused the radar pips, that explanation has been highly contested. Its also been speculated that the American radar pips were 7 IJN submarines running reconnaissance. What we do know is Kimura made it to Kiska on the 28th undetected and unharmed while the US warships were enroute miles back. No American ships were anywhere near Kiska on the 28th. Admiral Kimura pulled the ships into Kiska anchorage and evacuated the entire remaining forces on the island, all 5183 men onto 8 vessels all within 55 minutes. The Japanese soldiers made sure to spend their last moments on the island setting up a plethora of booby traps. Four days later Kimura and Kawase were back in Paramushiro, successfully evacuating Kiska without firing a single shot. The Americans had no idea the evacuation occurred.
