- 185 - Pacific War Podcast - the Liberation of Mindanao - June 3 - 10, 1945

Last time we spoke about the fall of Shuri. In the unforgiving terrain of Okinawa during May 1945, American Marines confronted fierce resistance from entrenched Japanese forces. Amidst heavy rain and dwindling supplies, General Buckner’s 10th Army battled uphill toward Shuri, a critical stronghold. With communication crumbling and morale wavering, the Americans pressed on, launching daring patrols. The situation reached a turning point when intelligence revealed the Japanese withdrawal plans. Buckner ordered continuous pressure, leading to the capture of significant strategic points like Shuri Castle, which was relentlessly bombarded prior to the Marine assault. On May 29, as the last remnants of Japanese forces fled south, American soldiers swept through Shuri, which lay in utter ruin, a testament to the devastating power of the campaign.

Last week we covered the fall of Shuri and today we continue the brutal brawl for Okinawa and the liberation of Mindanao.

As we last saw, the Japanese retreat from the Shuri line opened the path for General Buckner’s 10th Army to move southward, with only General Fujioka’s 62nd Division and a few minor rearguards standing in their way. On June 3, General Arnold’s 7th Division continued its offensive to the south. Colonel Pachler’s 17th Regiment successfully secured the area of Itokazu. Meanwhile, Colonel Green’s 184th Regiment pushed toward the coast to completely cut off the Chinen Peninsula. Colonel Finn’s 32nd Regiment was diverted into the rugged hills nearby to clean up any remaining resistance. To the west, despite persistent bad weather and challenging supply conditions, General Bradley’s 96th Division also achieved success. Colonel May’s 383rd Regiment secured the locations of Kamizato and Tera against relatively light resistance. At the same time, Colonel Halloran’s 381st Regiment advanced to seize the entire Inasomi area. Looking northwest, General Del Valle’s 1st Marine Division encountered stronger opposition. The bulk of the 5th Marines managed to push only as far as Tsukasa before being pinned down. In a strategic move, Colonel Griebel’s 2nd Battalion executed a wide swing through May’s rear area to capture the Gisushi region. Colonel Snedeker’s 7th Marines made steady progress through the Kokuba Valley, facing small enemy blocking forces, in order to extend the line held by the 5th Marines. Meanwhile, at sea, Admiral Ugaki launched his 9th mass Kikisui attack. This operation, featuring just 50 kamikaze aircraft, faced heavy obstacles due to Typhoon Viper but still managed to damage 2 vessels. In another development, after successfully occupying Torishima Island on May 12, Colonel Clarence Wallace’s 8th Marines landed on Iheyajima without encountering any opposition. In addition, preparations for the shore-to-shore assault of General Shepherd’s 6th Marine Division were completed. Colonel Shapley’s 4th Marines were set to land on the Nishikoku beaches before securing the Oroku Peninsula and its airfield. Consequently, during the early hours of June 4, Shepherd’s Reconnaissance Company successfully assaulted Ono-Yama Island, while Shapley’s assault battalions began the shore-to-shore movement to Nishikoku under the cover of artillery and naval bombardment. Despite some mechanical failures on the LVTs, the Marines successfully landed at 06:00 under sporadic machine-gun fire and then pushed onto the high ground 300 yards inland against minor resistance. After securing the initial foothold, the attack slowed against increasing resistance on the left flank. Because of this, the reserve 3rd Battalion was landed at 08:45 and subsequently advanced to the edge of the airdrome. 

During the day development of the enemy's defense had revealed an inordinate number of automatic weapons, ranging in various calibers up to 40mm. Subsequently, it was disclosed that the Japanese had stripped the armament from the air defenses and damaged aircraft in the area and integrated these weapons into the ground fortifications to stiffen materially the resistance on Oroku. Besides meeting with the most extensive mine fields yet encountered during the campaign, on this day the 6th Division had its first contact with an awesome weapon: an 8-inch rocket that exploded with terrific concussion. However, there was little fragmentation and accuracy was poor. While the noise the huge projectiles made, tumbling through the air end over end, sounded "like a locomotive from hell" to the troops, the rockets were mainly a source of annoyance and caused few casualties. Rockets continued to fall in the rear areas during the night, snipers and infiltrators were active, and the entire front came under intermittent heavy mortar fire. This landing allowed Shepherd to bring in Colonel Whaling’s 29th Marines by midday, which then secured the Kikibana area of Naha Bay, while the 4th Marines captured one-third of Naha’s airfield. To the east, the Americans encountered less resistance than before, as the 62nd Division and other minor rearguards completed their withdrawal from the intermediate lines south of Shuri to a reserve area south of the new Kiyamu Peninsula lines. Recognizing this change, Buckner shifted the corps boundary to the west, assigning General Geiger’s 3rd Amphibious Corps the task of isolating the Oroku Peninsula and occupying the Itoman-Kunishi sector, while General Hodge’s 24th Corps advanced toward the Yaeju Dake-Yuza Dake escarpment. 

As a result, the 7th Marines were able to move south to seize Takanyuta and isolate Admiral Ota's forces on the Oroku Peninsula. The atrocious weather had converted the already muddy roads to impassable morasses. Transport was hopelessly mired north of the Kokuba Gawa. South of the river the "trails were only negotiable by foot troops, vehicles could not have been used" even if it had been possible to bring them across the inlet. The 5th Marines managed to secure the Hill 107 area without opposition before being relieved by Colonel Mason’s 1st Marines. However, the 1st Marines were unable to continue their push south toward Shindawaku Ridge due to a flooded stream. Meanwhile, Mason’s 3rd Battalion attempted a wide envelopment through the 96th Division zone but was quickly halted in front of Tera. Food was scarce, but through the wholehearted cooperation of the 96th Division the Marines procured two meals of K rations per man. It was the considered opinion of at least one member of 3/1 that "this day probably was the most miserable spent on Okinawa by men of this battalion." To compound these problems and discomforts, the 3d Battalion also found itself without a supply route or communications with the regiment 11,000 yards to the rear.

Further east, the 383rd Regiment advanced rapidly, engaging isolated but strong enemy delaying groups as they secured the outskirts of Iwa. Matching this progress, the 381st Regiment advanced all the way to the hills north of Aragusuku, facing steadily increasing resistance. Additionally, while the 17th Regiment established positions controlling the Minatoga-Meka road, the 184th Regiment advanced against patchy and ineffective resistance until the Minatoga area was secured. The following morning, Admiral McCain’s Task Force 38 launched strikes on Okinawa and Kyushu. Unfortunately, poor situational awareness from Admiral Halsey caused the 3rd Fleet to inadvertently enter Typhoon Viper. This storm inflicted varying degrees of damage to four carriers, two escort carriers, three cruisers, one destroyer, and one tanker, while also destroying 76 planes. Additionally, kamikaze attacks succeeded in damaging the battleship Mississippi and heavy cruiser Louisville. Back on Okinawa, Shepherd’s attack on the Oroku Peninsula commenced and progressed slowly but steadily against uniformly stubborn resistance. The 4th Marines secured most of the airfield and the Toma high ground, while the 29th Marines fought laboriously to advance toward Mura and Oroku, gaining up to 1,000 yards.

To the east, the 7th Marines advanced to positions just north of Hanja, while the 1st Marines bypassed the inundated area in front of them by swinging east and following their 3rd Battalion toward Iwa. In fact, Mason’s 3rd Battalion launched another attack aimed at Shindawaku Ridge, advancing over 3,000 yards to the area west of Iwa. Despite muddy conditions and rainy weather, Hodge’s infantrymen continued to penetrate the enemy outpost zone, developing the edges of the main Japanese battle position. The outpost line of Kiyamu Peninsula was fully manned on June 4. Japanese Army headquarters estimated that the strength of its now concentrated forces totaled 30000, distributed as follows: 24th Division and attached units, 12000; 62nd Division and attached units, 7000; 44th IMB and attached units, 3000; 5th Artillery Command and attached units, 3000; and units directly under 32nd Army command, 5000. The difference in total strength between the 50000-man estimate late in May and the 30000 left in Kiyamu Peninsula was attributed to "attrition during retirement operations." Only about 20% of the remaining troops were survivors of the original crack infantry-artillery units; the rest were untrained rear echelon personnel or Boeitai. Most senior commanders at battalion level and above were still alive, however, and capable of bolstering the fighting spirit of their motley collection of men. But the 32nd Army had suffered grievous losses in weapons and equipment since L-Day. Hand grenades and explosives were almost entirely expended. 4 out of every 5 machine guns had been destroyed, and the supply of heavy infantry cannon and mortars had been reduced to the vanishing point. Despite the fact that 2 150mm guns, 16 150mm howitzers, and 10 AAA guns had been successfully withdrawn to the Kiyamu battle position, artillery ammunition levels were insufficient for more than 10 days of sustained firing. General Ushijima's 32nd Army was in desperate straits, its destruction merely a question of time, but the tradition, discipline, and indoctrination of Japanese military forces promised only a violent, last-ditch, man-to-man struggle before the battle for Okinawa was ended.

By June 6, the 7th Division reached the outskirts of Gushichan, and the 96th Division advanced toward Shindawaku and Tomui. To the west, the 1st Marines finally captured Shindawaku and cleared the bypassed area behind them. Meanwhile, the 7th Marines attacked toward Hill 108, advancing 1,000 yards before encountering stiff resistance and ultimately dug in around Dakiton. Additionally, Colonel Roberts’ 22nd Marines arrived to contain the Oroku Peninsula in the Hill 103 sector. Although the 29th Marines and Shapley’s 1st Battalion made little progress in the Oroku-Mura area due to strong enemy resistance. Meanwhile the terrain confronting the 3rd Battalion there "consisted of a series of small temple-like hills, each of which had been converted into a fortress . . . from which mutually supporting automatic weapons could cover adjacent positions and deny the open ground between the hills." These gun positions were well dug-in and impervious to artillery fire. Because the narrow roads in the area had been made impassable by mines and shell cratering, tank support was not forthcoming, and a day of bitter fighting netted 3/29 a gain of a scant 150 yards. The remainder of the 4th Marines attacked Naha Airfield where counter fire from tanks, artillery, and support craft was immediately laid down. An urgent call for an air strike on the island was answered in less than half an hour, and "as rack after rack of bombs fell on the Nip positions, the troops stood up and cheered." The artillery piece was soon silenced, but 20mm fire was received spasmodically. Nevertheless, 3/4 pressed forward with its open flank covered by continued air strikes on Senaga Shima and completed the capture of Naha airfield before noon, whence they pushed south toward Gushi. At sea, kamikaze attacks crashed into and damaged two destroyer minesweepers, while also causing further damage to escort carrier Natoma Bay and destroyer Anthony on June 7. That day, Shepherd’s Marines faced stiff resistance all along the front. The 4th Marines reduced Little Sugar Loaf where stiff resistance and bitter fighting characterized the action in the center and on the left of the 4th Marines' area. However, the attack forged ahead against machine-gun fire coming "from everywhere," while "countless caves were methodically cleaned out and sealed by the old process of direct fire, flame, and demolitions."Meanwhile the 29th Marines entered Oroku, and the 22nd Marines captured Hill 103 and the area south of Tamigusuki. 

To the southeast, the 7th Marines overran Hanja and Hill 108, ultimately digging in just north of Zawa and linking up with the 1st Marines, which also advanced up to 1,200 yards as they secured Hill 75 and pushed toward Yuza. Further east, the primary offensive efforts of the 7th and 96th Divisions on June 7 and 8 were focused on probing enemy defenses and advancing assault battalions to more favorable positions for an attack. Additionally, by the afternoon of June 8, the 32nd Regiment successfully relieved the exhausted 184th in the Gushichan area. On that same day, the 1st Marines pressed forward to the high ground overlooking the Mukue River, while the 7th Marines moved through Zawa and began probing enemy positions in Itoman, encountering stiffened resistance. The first LVT's, supported by LVTa's, arrived at the newly-uncovered beaches at noon on 8 June, and shortly thereafter General Hodge sent General del Valle "congratulations for cutting the island in two."

Meanwhile, on Oroku, the 29th Marines made little progress as they stalled at a key ridgeline on the left. The 4th Marines committed all three of their battalions to the attack, successfully securing the areas of Hill 39 and Gushi Ridge. The 22nd Marines continued to pivot on their right, seizing Hill 55 and making good progress along the front toward Chiwa and Tomigusuki. On June 9, although the 22nd Marines managed to secure Hill 55 and push to Hill 28, little advancement was achieved to the north. Concurrently, the 4th Marines were able to slowly push to the outskirts of Chiwa and Uibaru, with patrols clearing out Chiwa and Whaling’s 3rd Battalion extending the front to the north. The action in the zone of the 4th Marines on 9 June remained unchanged from that of preceding days: “The advance was still slow and tedious against bitter resistance. Every Jap seemed to be armed with a machine gun, and there was still the same light and heavy mortar fire. Casualties continued to mount and the number of Japs killed soared over the maximum of 1500 which were supposed to be defending and there were still plenty left.”

In the meantime, to the south, Del Valle sent strong patrols across the Mukue, which began to encounter significant enemy resistance. Consequently, the 7th Marines were unable to push toward Tera and Itoman. Further east, Hodge finally launched a corps attack to the south. The 96th Division focused its efforts on softening the enemy positions on the escarpment in front of them, while the 7th Division carried out the offensive. The 32nd Regiment attempted to attack the eastern end of Hill 95 but was unsuccessful; however, they managed to locate and identify the most troublesome sources of enemy fire for destruction. On a more positive note, the 17th Regiment gained a precarious foothold on the southern end of Yaeju Dake, just north of Nakaza, where they would withstand several Japanese counterattacks throughout the night. The first and greatest obstacle confronting Wallace's attack was the open ground over which both assault companies had to move. Wallace used all available support and the men camouflaged themselves with grass and rice plants, but enemy fire began almost as soon as the leading platoons moved into the open. The infantrymen crawled through the slimy rice paddies on their stomachs. Within an hour Company I was strung from the line of departure to the base of the objective which two squads had reached. About this time the Japanese opened fire with another machine gun, separating the advance squads with a band of fire. This left one squad to continue the attack; the remainder of the company was unable to move, cut off by fire or strung across the rice paddies. Those men in the squad still free to operate lifted and pulled each other to the edge of the cliff and crawled quietly forward through the high grass on top. Pfc. Ignac A. Zeleski, a BAR man, moved so stealthily that he almost touched the heels of one Japanese. Zeleski killed him, and the other men killed eight more Japanese within the first ten minutes. Another squad reached the top of the escarpment about an hour later but was caught in cross and grazing fire from three machine guns, and the entire 8-man squad was killed. Gradually, however, a few more men reached the top, and by evening there were twenty men from Company I holding a small area at the escarpment rim. Company K had a similar experience. Accurate enemy fire killed one man, wounded two others, and halted the company when it was from 200 to 300 yards from its objective. For forty-five minutes the attack dragged on until S/Sgt. Lester L. Johnson and eight men maneuvered forward through enemy fire, gained the high ground, and concentrated their fire on the enemy machine gun that was firing on the remainder of the company. This did not silence the gun but did prevent the gunner from aiming well, and Johnson waved for the rest of the company to follow. By 1330 of 9 June Company K was consolidated on the southeastern tip of the Yaeju-Dake. That evening, three small but determined counterattacks, with sustained grenade fire between each attempt, hit the small force from Company I, which held off the attackers with a light machine gun and automatic rifles. Additionally, Wallace’s 1st Battalion successfully landed unopposed on Aguni Island to establish air warning and fighter director installations. 

However, it’s now time to leave Okinawa and shift our focus to the Philippines to cover the continuation of General Eichelberger’s Mindanao Campaign. As we last saw, by May 3, General Sibert’s 10th Corps had successfully invaded the island and secured the key Kabacan road junction. General Woodruff’s 24th Division occupied Digos and Davao, while General Martin’s 31st Division advanced up the Sayre Highway toward Kibawe. Thanks to the arrival of the 162nd Regiment from Zamboanga, the 31st Division was now able to send another regiment, the 155th, to assist in the push north against General Morozumi’s 30th Division. In response to the rapid advance of the 31st Division as far as Kibawe, Morozumi was assembling his units at Malaybalay in preparation for a retreat eastward to the Agusan Valley. He dispatched the 3rd Battalion of the 74th Regiment to the south to delay the Americans in the vicinity of Maramag, at least until May 10.

Meanwhile, after capturing Davao, Woodruff’s goal was to mop up the sector and destroy General Harada’s 100th Division in the mountainous interior. The 100th Division located the southern anchor of its defenses at Catigan, 13 miles southwest of Davao, and the northern anchor in hills some twelve miles north of Davao. The Davao River, flowing generally south-southeast into Davao Gulf at Davao, divided the defensive forces into two groupments. The Right Sector Unit, west of the river, was composed of 5 infantry battalions, 3 regular and 2 provisional. The territory east of the river was the responsibility of the Left Sector Unit--2 regular infantry battalions, 2 provisional battalions, and the Air Force's Hosono Unit of ill-armed service personnel. The Right and Left Sector Units had a little artillery attached, for General Harada kept under his direct control most of the artillery as well as many engineer and service units. As a reserve Harada had about a battalion of regular infantry. The central and strongest portion of Harada's defenses rested its right on rising ground overlooking Libby Airdrome, two miles northwest of Talomo on the coast. From this point the central defenses, along which Harada initially deployed three battalions, extended eastward across the Talomo River and some rough hills to the west bank of the Davao River. The focal point of the central defenses was Mintal, four miles up Route 1-D from Talomo. Anticipating ultimate withdrawal into the mountains via Route 1-D, the southeastern section of the so-called Kibawe-Talomo trail, Harada had prepared defenses in depth along the highway and along ancillary roads paralleling it. Much of the region west of the Davao River from Talomo northwest twelve miles to Calinan was covered with overgrown abaca, or hemp, plantations. Resembling banana plants, and growing to a height of about 20 feet, the abaca plants had originally been planted in rows 10 feet apart, with 10 feet between plants. With harvesting slack during the war, the plantations had become thick with shoots, and older plants had grown to a foot or so in diameter. Plants of various sizes were, in April 1945, scarcely a foot apart. Visibility was virtually nil, and the heat at the hemp plantations was like that of an oven.

With the 162nd Regiment taking control of Digos and the area stretching from Illana Bay's shores inland to Kabacan, Woodruff was now free to utilize his entire division to engage the enemy forces in the Davao area. At the start of May, the 21st Regiment had already launched an attack to clear Libby Airdrome, Route 1-D between Mintal and Talomo, and Mintal itself. They successfully reached Mintal by May 3, effectively forcing Harada to reinforce his defenses near the Talomo River. Although the airdrome was cleared two days later, subsequent efforts up Route 1-D toward Mintal were repelled by fiercely defending Japanese forces. Due to this resistance, elements of the 34th Regiment attempted to drive north along the high ground on the east bank of the Talomo River to bypass the Japanese defenses on Route 1-D. On May 8, the 21st Regiment finally crossed to the east side at Mintal; however, in the face of Japanese artillery, mortar, and machine-gun fire, they had to withdraw back to the west bank two days later. At the same time, the 19th Regiment was expanding its hold in the Davao area, striking into the high ground controlling the coast road immediately west of the Davao River on May 10. They also cleared scattered Japanese strongpoints on hills just north of Davao and on Samal Island. Two days later, the 21st Regiment again attacked northward along the east bank of the Talomo, successfully clearing out numerous positions from which the Japanese had directed fire on Route 1-D. By May 14, the highway all the way north to Mintal was finally secured.

In the meantime, the 124th Regiment started north from Kibawe on May 6. However, the recently arrived Japanese defenders at Maramag managed to delay the occupation of this town until May 12, thus accomplishing their task more than adequately. Despite this success, Eichelberger had shrewdly sensed that Morozumi would attempt to make a last stand in the hills northwest of Davao. Therefore, he decided to land the 108th Regiment behind enemy lines in the Macajalar Bay area to expedite the conquest of Mindanao and open a new supply route to the 31st Division. Accordingly, on May 10, the 108th Regiment landed unopposed along the southeastern shore of Macajalar Bay, making contact almost immediately with guerrilla units operating in the region. This regiment then drove down the Sayre Highway to meet the 31st Division advancing from the south, encountering no significant resistance until May 13, when it faced strong Japanese defenses near Dalirig. With its rear protected by the recently landed 3rd Battalion of the 164th Regiment, the 108th proceeded to attack the enemy positions with great intensity, finally forcing the Japanese to retreat to the area east of Malaybalay by May 16. Concurrently, on May 13, the 155th Regiment passed through the 124th Regiment to continue the drive northward, meeting little opposition but facing supply problems. By May 20, the Americans finally reached the outskirts of Malaybalay, where fire from remnants of the 30th Field Artillery Regiment halted their advance. Realizing that the regiment could not haul its weapons into the mountains east of Malaybalay, Morozumi had left the unit at Malaybalay to fight a rear-guard action, which was successful in keeping the 155th Infantry out of the town until late on 21 May. On 22 and 23 May the 155th continued up Sayre Highway, encountering elements of Morozumi's Northern Sector Unit that had not learned that American troops had reached Malaybalay and were still withdrawing southward to join the 30th Division's main body. Pressed by troops of the 108th Infantry, 40th Division, which had already landed at Macajalar Bay, the retreating forces gave the 155th Infantry little trouble and, about 1400 on 23 May, the 155th made contact with the 108th Infantry near Impalutao, twelve miles northwest of Malaybalay. Its share in the task of clearing Sayre Highway cost the 31st Division approximately 90 men killed and 250 wounded, while the 108th Infantry, 40th Division, lost roughly 15 men killed and 100 wounded. Together, the two units killed almost 1,000 Japanese during their operations along the highway, and captured nearly 25 more. Nevertheless, the 30th Division had managed to escape east this time to establish new positions near Silae.

Back in Davao, on May 15, Woodruff directed the 21st and 34th Regiments to attack abreast to the north and northwest, targeting the Japanese center. Meanwhile, the 19th Regiment advanced north to clear the northeastern shores of Davao Gulf, link up with the guerrilla forces north of the gulf, and ultimately swing westward against the 100th Division's left flank forces. Surprised by the lack of enemy attacks against his flanks, Harada concluded that the American forces intended to neglect his flanks in favor of a frontal assault on his center. As a result, he weakened the defenses of the Left Sector Unit to reinforce the Mintal line, leaving only Admiral Doi’s air-naval troops to defend his left flank. On May 17, Woodruff renewed his offensive. The 19th Regiment struck north to establish contact with the guerrilla 107th Division, while the 34th Regiment began clearing the coastal hills between the Talomo and Davao Rivers and attacked northwest toward Tugbok. The 21st Regiment also drove north toward Tugbok in the face of determined opposition. Progress in the following days was slow due to intense artillery, machine-gun, rocket, mortar, and rifle fire. However, by May 27, the 21st Regiment seized the Tugbok area, with the 34th Regiment arriving the next day to relieve them. As Harada’s strongest defenses had been breached, he ordered a general withdrawal to a hastily established second line crossing Route 1-D in the vicinity of Ula. Furthermore, the 19th Regiment managed to establish contact with the guerrillas by May 24 as it secured Route 1 north of Davao.

On May 29, the 19th Regiment struck westward toward Doi's Mandog defenses, closing in two days later to engage the naval troops in fierce combat. Concurrently, on May 30, the 34th Regiment attacked toward Ula, which fell easily the following day, though progress then slowed in the face of fanatic resistance. Reinforced by the recently arrived 3rd Battalion of the 163rd Regiment on June 4, the 34th began to make headway beyond Ula on the secondary road, gaining one mile by June 6 before swinging east toward Mandog. The next day, having overrun Doi’s outer defenses, the 19th Regiment advanced steadily into the main positions near Mandog, which ultimately fell by June 9, just as the 34th was reaching the area. Continuing northward, the 34th was almost three miles north of Ula along both roads and found few signs of organized Japanese resistance by June 11. However, the 19th Regiment would not clear the hills north of Mandog until June 15. In the meantime, the 21st Regiment struck north from Lamogan on May 31 along secondary roads west of Route 1-D, ultimately seizing Wangan on June 16 and forcing Harada’s battered forces to commence a full retreat northward in disarray. After the fall of Culanan three days later, Harada finally decided to retreat to a new line near the Bannos River. Yet Woodruff’s troops continued to pursue them, rapidly crossing the Tamogan River and inflicting heavy casualties on the retreating enemy until they reached the mountain barrio of Kibangay on June 26, where the pursuit was finally halted.

Looking back to the north, with Sayre Highway cleared, the 124th Regiment began probing into the mountains to the east in late May, encountering heavy resistance, rough terrain, bad weather, and supply problems. Nevertheless, by June 5, Morozumi abandoned his plan to hold the Silae area for a month and slowly began moving his best troops eastward toward Waloe in the Agusan River valley, harassed by Filipino guerrillas along the way. In the end, Silae was finally occupied on June 9, with troops of the 108th Regiment pushing further to the Bobonawan River four days later. Additionally, the 155th Regiment arrived on the Pulangi River on June 12, while elements of the 162nd Regiment struck twenty miles into the mountains east from Maramag by June 26. On June 25, the 1st Battalion of the 155th Regiment successfully landed on Butuan Bay and managed to reach Waloe before the Japanese on June 27, dispersing the 3rd Battalion of the 41st Regiment that was holding the area. However, the Japanese retreat was so slow that Morozumi was still assembling his forces about seven miles up the Agusan from Waloe by the end of the war. 

Far to the northwest, units of the 31st Division had been probing southeast along the upper section of the Kibawe-Talomo trail ever since early May, and on the 11th of that month a battalion combat team of the 167th Infantry launched the reconnaissance-in-force directed by General Sibert.  Japanese along this section of the trail, about 1,000 men in all, comprised a conglomerate mass of service troops with a small leavening of infantry. Control was vested in General Tomochika, chief of staff of the 35th Army, who had set up a small headquarters groupment near barrio Pinamola, about twenty miles southeast of Kibawe. The Japanese force had a defensive potential far greater than its strength and nature would indicate, for the terrain gave the Japanese every conceivable advantage. Bounded on both sides by dense jungle and thick rain forest, the trail as far as Pinamola ran up and down steep ridges and was scarcely jeep-wide. Rains of late May soon rendered all sections of the trail completely impassable to wheeled vehicles, and supplies had to come in by airdrop, supplemented when possible by hand-carrying parties and laden Carabaos. The mud was so deep that often troops had to pull, push, or even jack the Carabaos out of gooey holes. Delayed by the Japanese, the terrain, and the weather, the 167th Infantry's battalion did not reach the Pulangi River, thirteen miles southeast of Kibawe, until 29 May. 

Then, although the Japanese from the trail could no longer offer any threat to the 31st Division, the battalion continued south toward Pinamola, aided considerably by guerrillas. The remnants of the 1st Battalion, 74th Infantry, and the South Sector Unit, 30th Division, which had been driven into the mountains along Highway 3 by the swift American advance in central Mindanao had meanwhile been attached to Tomochika’s forces early in June. Troops of the 167th Infantry finally reached Pinamola on 30 June as the remaining Japanese were withdrawing southward another eight miles to the crossing of the Kuluman River. Progress as far as Pinamola had cost the 167th Infantry approximately 60 men killed and 180 wounded, while the Japanese had lost almost 400 killed along the same section of the trail. Elements of the 167th Infantry held along the northwestern section of the Kibawe-Talomo trail until the end of the war, and as of 15 August the regiment was preparing to send troops across the Kuluman River to continue the advance southeastward. On that date nearly 30 miles of Japanese-improved trail, only 19 air miles--still separated the 167th Infantry from guerrilla units operating in the vicinity of Kibangay. Organized remnants of Harada's 100th Division holed up until the end of the war in rugged terrain north of this 30-mile stretch of the trail.

Finally, the 24th Reconnaissance Troop successfully landed on the southeastern shore of Sarangani Bay on July 4 to establish contact with the guerrilla 116th Regiment, subsequently clearing the bay's shores against negligible resistance. On July 12, the 1st Battalion of the 21st Regiment landed on the northwest shore, just as two provisional battalions were arriving in the area from different directions. The three forces began to clear the area, successfully locating and destroying the only Japanese unit in the region by July 25. This concluded the campaign in Mindanao, during which the Americans suffered 820 men killed and 2,880 wounded. In turn, almost 10,540 Japanese were killed in eastern Mindanao by June 30, with the pursuing Filipino-American units killing another 2,325 Japanese by the war's end. Roughly 600 Japanese prisoners were captured, over 250 of whom were civilians, before August. After the war, about 22,250 Japanese troops and 11,900 civilians turned themselves in.
