Last time we spoke about the First Okinawa Counteroffensive. The US Marines launched a formidable assault on Okinawa, confronting the entrenched Japanese 32nd Army. This dramatic struggle culminated in Operation Ten-Ichi-Go, Japan's final counteroffensive, marked by the ill-fated mission of the battleship Yamato, which met its demise under relentless air attacks. As American forces advanced, they faced significant resistance, particularly at the Shuri fortified zone. Colonel Yahara voiced concerns over a night counterattack planned for April 12, predicting disaster and chaos for disoriented troops unfamiliar with the terrain. Despite his warnings, Japanese forces executed a counteroffensive that faced harsh setbacks. As the Americans consolidated their gains, pressures mounted on their adversaries. Nevertheless, the relentless nature of the battle highlighted the stark contrast between the courage of the soldiers and the emerging futility of their cause, underscoring the inevitable tide of defeat facing Japan at this pivotal moment in history.

By April 18, significant progress had been made in the offensive operations against Iejima and the Motobu Peninsula, as seen in Iwo Jima; most notably, General Hodge’s 24th Corps was prepared to launch a full-scale offensive to the south with three divisions in line. On the morning of April 19, following the successful initial advance of the 106th Regiment, the largest artillery concentration ever used in the Pacific War heralded the dawn attack. Simultaneously, the campaign's most extensive airstrike was carried out, bolstered by the naval bombardment from Admiral Spruance’s fleet. The assault teams moved forward, optimistic that the heavy barrage had either destroyed the enemy or left them too dazed to fight back. However, they soon faced disappointment; the Japanese forces, sheltered in their caves, had emerged largely unscathed and quickly took up their positions. To the east, General Arnold’s 7th Division launched an attack with the 32nd and 184th Regiments, targeting Skyline Ridge, Ouki Hill, and Hill 178. While most of the 32nd Regiment engaged the entrenched enemy on Skyline Ridge with support from armored flamethrowers, Colonel Finn’s 2nd Battalion and Colonel Greene’s 2nd Battalion advanced about 500 yards unopposed towards Ouki Hill, only to be halted by a fierce barrage of Japanese fire. As efforts to progress stalled throughout the day, they had to retreat, which also compelled Finn’s beleaguered 3rd Battalion to withdraw. Meanwhile, the remainder of the 184th Regiment attempted to advance through the coral formations of the Rocky Crags but was quickly pinned down by the determined defenders. Two medium tanks and three armored flame throwers rumbled southward from the 7th Division's lines on the coastal flats, passed through Ouki, and quickly moved into position at the tip of Skyline Ridge. They poured shot and flame into the cluster of enemy-occupied tombs and emplacements at the lower extremity of the ridge. The long jets of orange flame probed all openings in the face of this part of Skyline, and dark, rolling masses of smoke billowed upward. This was a new spectacle for the waiting infantry, who watched fascinated. For the enemy who died in the searing flame inside their strong points, there was hardly time to become terror-stricken. This phase of the attack lasted fifteen minutes, and then, just after 0700, the infantry moved up. All the Japanese on the forward face of the tip had been killed by the flame, but there were others on the reverse side who denied any advance across the crest. The battle of the infantry quickly erupted and smoldered along the narrow knife-edge line of Skyline Ridge. American troops clung desperately to the forward slope through two Japanese counterattacks, in which the enemy crowded forward into his own mortar fire to hurl grenades and satchel charges.
At the same time, General Bradley's 96th Division launched an assault with the 381st and 382nd Regiments advancing side by side, aiming for Nishibaru Ridge, Tombstone Ridge, and the Tanabaru Escarpment. The initial capture of several small hills west of Tombstone Ridge went smoothly, but the 382nd faced stiffer resistance on Tombstone itself, managing to maintain a fragile position along the northwest edge of the ridge and partway down its west slope by nightfall. Meanwhile, the 1st Battalion of the 381st Regiment successfully took Kaniku while pushing toward Nishibaru Ridge. However, most of the assault was executed by the 3rd Battalion, which advanced under heavy fire over the ridge crest to the upper part of Nishibaru village, where it was ultimately halted and forced to retreat by resilient defenders. In General Griner's 27th Division sector, the 106th Regiment had already cleared Machinato Inlet and secured a position at the western end of the Urasoe-Mura Escarpment. The 2nd Battalion attempted to push south following a successful night attack but encountered a series of caves, tombs, and tunnels west of Route 1, leading to a stalemate. This marked the beginning of what would later be termed the Item Pocket battle. Meanwhile, the 1st Battalion of the 105th Regiment conducted a frontal assault on Kakazu Ridge while Griner executed a sweeping tank maneuver around the east end of the ridge.
The only other 27th Division unit on the front line ready to join in the initial assault was the 1st Battalion of the 105th Infantry. This battalion was deployed along Kakazu Gorge, with Kakazu Ridge, immediately in front, its initial objective. Company C was on the left, next to the Ginowan-Shuri road; Companies B and A, in the order named, were to the west, the latter being initially in reserve. The attack of the 1st Battalion was planned to combine a frontal assault against the ridge with a sweeping tank attack around the east end of Kakazu Ridge. The two forces were to meet behind the ridge near the village of Kakazu and to join in a drive to the Urasoe-Mura Escarpment beyond. The Japanese had guessed that a tank-infantry attack would try to penetrate their lines between Nishibaru Ridge and Kakazu Ridge, and they had prepared carefully for it. Their plan was based on separating the infantry from the tanks. The 272d Independent Infantry Battalion alone devised a fire net of four machine guns, two antiaircraft guns, three regimental guns, and the 81-mm. mortars of the 2d Mortar Battalion to cover the saddle between the two ridges. The machine guns were sited at close range. In addition, two special squads of ten men each were sent forward to the saddle for close combat against the infantry. One group was almost entirely wiped out; the other had one noncommissioned officer wounded and three privates killed. The enemy defense also utilized the 47-mm. antitank guns of the 22d Independent Antitank Gun Battalion and close-quarters suicide assault squads. So thorough were these preparations that the Japanese boasted "Not an infantryman got through." It was here in the Kakazu-Urasoe-Mura Escarpment area that the most extensive reorganization of Japanese units had taken place just before the American attack. The remnants of badly shattered battalions were combined into a composite unit of about 1,400 men that consisted largely of members of the 272d Independent Infantry Battalion but also included elements of the 13th, 15th, and 23d Battalions. The 21st Independent Infantry Battalion stood ready to support the 272d. The 2d Light Machine Gun Battalion added its fire power. Although the infantry soon found themselves pinned down by intense Japanese fire, the tanks managed to reach Kakazu village, which was heavily damaged and set ablaze over the next three hours.
Despite their efforts, the failure of the 1st Battalion eventually compelled the tanks to retreat, prompting the 2nd Battalion of the 105th Regiment to attempt an attack towards the eastern end of Kakazu Ridge without success. Meanwhile, the 3rd Battalion descended from Kakazu West, bypassed Kakazu village, and successfully reached the summit of the Urasoe-Mura Escarpment. This unexpected achievement led Colonel Winn to decide to reposition the remainder of the 105th around the western end of Kakazu Ridge to join the 3rd Battalion on the escarpment, effectively abandoning the main enemy front. In other areas of the escarpment, the 106th Regiment was unable to advance southward but managed to extend its lines eastward to connect with Winn’s 3rd Battalion. Consequently, the major offensive on April 19 failed to produce any significant breakthrough, resulting in 720 casualties.
To the north, General Shepherd initiated a final push toward the north coast on the same day, with the 4th and 29th Marine Regiments advancing through complex networks of caves and trenches facing minimal resistance, but they halted at the elevated terrain around Hill 302. Additionally, patrols from the 22nd Marines moved south from Hedo Misaki and successfully captured Aha on the eastern coast. On Iejima, General Bruce also persisted with his main offensive against the Japanese strongholds on Bloody Ridge, as the 3rd Battalion of the 305th Regiment advanced eastward against the northern section of Ie, while Colonel Hamilton's 2nd and 3rd Battalions attacked northward. Backed by artillery and mortars, the infantry engaged in fierce skirmishes marked by hand-to-hand combat, moving from one stronghold to another.
Following another preparatory bombardment, Colonel Smith initiated a second assault at 14:30, effectively capturing the slopes of the Pinnacle through a series of rushes despite intense machine-gun and mortar fire. Leading elements of the 306th came under intense mortar and small-arms fire as they left the line of departure 600 yards northeast of the base of Iegusugu. The Pinnacle loomed above them, its slopes covered with masses of torn and twisted vegetation. Describing the Pinnacle on the morning of the 20th, General Randle, assistant division commander of the 77th, stated: "It is a damned highly fortified position with caves three stories deep, each house concrete with machine guns in and under. Whole area of village and circumference of mountain a maze of machine gun, mortar, and gun positions little affected by artillery fire we have poured on. Even as this message was on its way to the 77th Division command post, the 306th was winning a hold on the formidable position.
By the end of the day, Smith’s 1st Battalion was positioned across the northern slopes of Iegusugu; the 3rd Battalion had advanced to within 400 yards of the peak on the eastern side; and the 2nd Battalion had pivoted south to keep pace with the other units of the 306th. Meanwhile, Hamilton’s 2nd Battalion succeeded in securing the buildings on Government House Hill; Coolidge’s 1st Battalion regained control of the hill from the east; Hamilton’s 3rd Battalion established a line at the base of Iegusugu extending to the recently captured Bloody Ridge; and Coolidge’s 3rd Battalion made limited progress as it moved slowly eastward. However, during the night, over 400 Japanese troops, including women armed with spears, launched a fierce counteroffensive against Bloody Ridge, nearly forcing the Americans off Government House Hill. By dawn on April 21, as the counterattack diminished, resulting in heavy casualties on both sides, Hamilton’s 3rd Battalion was dispatched to relieve the 2nd Battalion, starting the cleanup of the now-secured Bloody Ridge. Coolidge’s 3rd Battalion also successfully repelled a strong counterattack from the north before resuming its advance eastward, destroying several enemy positions as it established a line extending south from a small lake at the southwest base of Iegusugu. In the meantime, the 306th Regiment strengthened its hold on Iegusugu throughout the morning, with the 3rd Battalion launching a successful assault on the eastern slopes, while the 1st and 2nd Battalions continued to clear caves and pillboxes on the northern and northwestern slopes.
Shortly after noon, Hamilton’s 3rd Battalion and Coolidge’s 1st Battalion began advancing northward against light resistance to secure the southern slopes of Iegusugu. Simultaneously, Smith’s 2nd Battalion and Coolidge’s 3rd Battalion launched a coordinated assault to capture the southwest slopes, where they encountered stronger opposition. By mid-afternoon, all units at the Pinnacle were busy mopping up, systematically destroying and sealing the enemy's underground passages and strongholds over the next five days. By midafternoon of April 21 all units on the Pinnacle were engaged in mopping up. The exterior of the Pinnacle was secure, but Japanese still remained in subterranean passages and strongholds from which they made sallies against the troops. The openings were systematically blown out and sealed off. The 307th alone captured or destroyed during the day five 81-mm mortars, five knee mortars, one 75-mm howitzer, and two 47-mm anti-tank guns. These were some of the weapons that had held the Americans off Bloody Ridge for three days. For five days after Ie Shima was declared secure, elements of the 77th Division mopped up remaining groups of the enemy, sealed caves, destroyed pillboxes, marked or removed the thousands of mines that were still on the island, and buried the dead. During this period hundreds of Japanese were killed in and around the Pinnacle, in the town of Ie, and in caves along the coast line. Removal of mines on the airfield and on the roads feeding it was given priority in order to speed up airfield construction. The last noteworthy encounter on Iejima came during the night of April 22-23, when a group of Japanese soldiers and civilians, including women, all armed with rifles, grenades, and demolitions, rushed from caves on Iegusugu toward the lines of the 306th. They were all cut down without loss to American troops.
Ultimately, during the six-day battle on Iejima, the Americans killed 4,706 Japanese soldiers and captured 149, suffering 172 killed, 902 wounded, and 46 missing. Meanwhile, on April 20, the 4th and 29th Marine Regiments reached the north coast after eliminating organized resistance on the Motobu Peninsula, resulting in over 2,000 Japanese fatalities, while Shepherd’s Marines incurred 207 killed, 757 wounded, and six missing. The Fleet Marine Force Amphibious Reconnaissance Battalion seized Yagachi Island on April 21 and occupied Sesoko Island on April 22, with the 6th Reconnaissance Company making the final landing on Kouri Island on April 23. Following a night reconnaissance in rubber boats, the battalion, transported by armored amphibians, seized Yagachi Shima on 21 April. A leper colony of some 800 adults and 50 children was located on this island, but no resistance was encountered. Because aerial reconnaissance had reported Sesoko Shima to be occupied and defended, it was decided to launch an attack on that island with one reinforced regiment. But preliminary to the attack, a native was captured during an amphibious reconnaissance of the objective who revealed that the island was probably not occupied. A successive physical reconnaissance confirmed his statements. Consequently, Major Jones' command was also assigned this mission, and the battalion occupied Sesoko Shima on 22 April. Although no opposition was met, the operation was interfered with by more than 100 civilians, moving by canoe from islands to the west where food was running low, and "considerable difficulty was involved in coralling and controlling" them. On 23 April the 6th Reconnaissance Company, also mounted on and supported by LVT(A)s, executed a daylight landing on Kouri Shima, likewise finding no resistance. Concurrently, while the 29th Marines remained on the Motobu Peninsula, the 4th Marines moved to their designated area in northern Okinawa to assist the 22nd Marines in mopping-up operations, searching the mountainous interior for remnants of the Udo Force and independent guerrilla groups. Finally, on April 28, Colonel Udo's final 200 surviving members were successfully intercepted and eliminated while attempting to flee to the east coast, effectively concluding the northern Okinawa operation.
It’s now time to leave Okinawa and return to the southern Philippines to oversee the continuation of General Eichelberger’s operations. By the end of March, General Arnold’s Americal Division had successfully taken control of Cebu City and Lahug Airfield, but was encountering stronger resistance in the northern hills. By the end of March the Americal Division had acquired a good idea of the nature and extent of General Manjome's principal defenses, and had learned that it had already overrun some of the strongpoints along the Japanese outpost line of resistance. On the other hand, the division had not been able to pinpoint the Japanese flanks. With the enemy firmly entrenched and having all the advantages of observation, General Arnold knew that the process of reducing Manjome's positions would be slow and costly no matter what type of maneuver the Americal Division employed. Lacking the strength required for wide envelopments and specific information about the Japanese flanks, Arnold hoped he might achieve decisive results with a single sledgehammer blow against the Japanese center. He therefore decided to use the bulk of his strength in a frontal assault into the hills due north of Cebu City.
Consequently, on April 1, the 182nd Regiment, supported by Colonel Cushing’s guerrillas, launched a direct assault on the Japanese center, while the 132nd Regiment advanced along the west bank of the Butuanoan River and then moved westward to flank General Manjome’s left. Despite slow progress and heavy casualties, by April 11, the 182nd had diminished most of the significant defensive positions along the center of Manjome's second line, and the 132nd had managed to flank the Japanese left, reaching a crucial location on the far left of Manjome's final defensive positions. Additionally, the 164th Regiment had landed to bolster the offensive and was quickly advancing through the Mananga Valley to encircle the Japanese right and rear. By April 13, the 164th reached Babag Ridge, but its surprise attack was promptly repelled by the defenders. Meanwhile, the 132nd and 182nd Regiments resumed their assaults, with the latter capturing the last stronghold along the Japanese second line. Unbeknownst to the Americans, Manjome had already concluded that further resistance was futile and ordered a general withdrawal northward to begin the night of April 16. In the days that followed, Arnold’s three regiments engaged in a series of costly small unit attacks, gradually gaining ground, inch by inch.
On April 17, organized resistance in the Japanese stronghold began to falter as defenders retreated, and by evening, the Americal Division had neutralized all of Manjome's significant fortifications. In response to the Japanese withdrawal, the Americal Division quickly initiated a pursuit operation, successfully cutting off the retreat route to the remaining forces of the 1st Division in northern Cebu by the end of the month. By the first week of May, the 132nd Regiment launched an offensive to dismantle General Kataoka’s organized resistance, aided by guerrilla forces, and largely achieved its objective in a campaign that lasted until the month's end. The Americans and Filipinos then focused on mopping up the remnants of Manjome's forces, effectively eliminating the last pockets of Japanese resistance on Cebu by June 20.
Meanwhile, on April 11, the 3rd Battalion of the 164th Regiment landed unopposed on Bohol at beaches already secured by Major Ismael Ingeniero’s guerrillas. Patrols soon located the Japanese garrison inland, leading to the battalion's assault on its main positions from April 17 to April 20, culminating in the overrunning of the last organized opposition by April 23. On April 26, the remaining elements of the 164th Regiment landed unopposed on southern Negros and moved inland to search for the Japanese garrison. By April 28, they discovered the 174th Independent Battalion, but their initial attacks were successfully thwarted by the defenders. Nonetheless, a coordinated offensive commenced on May 6, which successfully compelled the Japanese to retreat and disperse by the end of the month. The 164th then neutralized a final resistance pocket between June 7 and 12, effectively ending Japanese opposition on Negros and completing the 8th Army’s campaign to reclaim the central Visayan Islands.
Eichelberger's operations in the southern Philippines were far from over, as Major-General Franklin Sibert's 10th Corps, comprising the reinforced 24th and 31st Divisions, was preparing to launch the invasion of Mindanao, known as Operation Victor V. The initial strategy had Major-General Roscoe Woodruff’s 24th Division landing on the shores of Illana Bay on April 17 to quickly secure the Malabang-Cotabato area, followed by Major-General Clarence Martin’s 31st Division five days later for the final advance toward Davao.
Illana Bay lies nearly a hundred miles northwest of the main objective in eastern Mindanao, the Davao area, and only a poor road connects its beaches to Davao. Still, 8th Army had ample reason to select Illana Bay as the site of the initial assault. For one thing, the army knew that the Japanese had their main concentrations in the Davao region, where they seemed especially well prepared to repel an amphibious assault. It would be foolish to stick one's hand into a hornet's nest if there were no urgency for such action, and 8th Army could not, of course, avoid the long view that the eastern Mindanao operation was in essence a mopping-up campaign rather than an action of great strategic importance. Second, the Illana Bay area was relatively weakly defended--the 24th Division would have a much better chance to achieve tactical surprise there. Finally, 10th Corps would have to seize and rehabilitate an airstrip quickly so that land-based aircraft could provide proper support for subsequent operations in eastern Mindanao, other air bases being too distant. A reasonably good strip existed at Malabang, on the northwestern shore of Illana Bay. Given the estimate that the Japanese maintained a weak garrison at Illana Bay, Malabang seemed the spot for the main assault.
However, by early April, Colonel Wendell Fertig’s guerrilla forces had taken control of the entire Malabang region, forcing the Japanese garrison to retreat. Consequently, Sibert adjusted his plan, directing Rear-Admiral Albert Noble's Task Group 78.2 to deploy only one battalion at Malabang, with the remaining forces of the 24th Division landing near Parang. The Japanese forces in Mindanao numbered over 43,000, including troops from Lieutenant-General Morozumi Gyosaku’s 30th Division, Lieutenant-General Harada Jiro’s 100th Division, and Rear-Admiral Doi Naoji’s 32nd Naval Special Base Force. General Suzuki of the 35th Army was in overall command of these troops, but he first needed to escape from Cebu to assert his authority. Thus, Suzuki and his staff departed northern Cebu on April 10, using five landing craft. Unfortunately, the boats became separated, leading to an emergency landing near Dumaguete before they could continue their journey on the night of April 16. Tragically, Suzuki’s vessel was intercepted and destroyed by a PT boat off the southern tip of Cebu on April 17. Only his chief of staff, Major-General Tomochika Yoshiharu, managed to reach Cagayan on the night of April 20 after several days adrift.
Nominal command in Mindanao rested with General Morozumi, who became de jure commander of the 35th Army after General Suzuki's death during the latter's voyage from Cebu. But Morozumi chose not to exercise his authority except insofar as to largely ignore advice from General Tomochika, 35th Army chief of staff, who reached Mindanao in late April. Beset with formidable communications difficulties, and realizing that most inhospitable terrain separated the main bodies of the 30th and 100th Divisions, Morozumi believed he could render his best service by staying with the 30th, leaving General Harada and Admiral Doi more or less to their own devices. Neither Harada nor Morozumi had any offensive missions. Rather, in accordance with Yamashita's December 1944 plans, the Japanese on Mindanao were to direct their efforts to pinning down as many American units as possible in order to delay the progress of the war. Harada and Morozumi had little hope of conducting organized, major defensive operations for more than two months. Once American forces had overrun their prepared defenses, the two planned to retreat into largely unexplored mountains of east-central Mindanao, organizing a last-stand area like Yamashita's in the Asin Valley of northern Luzon. The 30th and 100th Divisions were not in good shape to conduct a delaying, defensive operation either. Hopelessly isolated, short of artillery, small arms ammunition, transportation, and communications equipment, they had no chance of obtaining supplies. They had some stocks of food, but their transportation shortage, coupled with the poor condition of eastern Mindanao roads would make it most difficult for the Japanese to move their food from central depots to the mountains. The Japanese commanders thus knew that once an invasion of eastern Mindanao began they would enter upon a battle they could not win, and they definitely had no relish for a defense to the death in place.
After an uneventful journey, Sibert's 10th Corps began landing on Mindanao on the morning of April 17. Troops from the 533rd Engineer Boat and Shore Regiment went ashore on the small Ibus Island, while the 3rd Battalion of the 21st Regiment joined Fertig's guerrillas on the beach near Malabang. Company K secured Bongo Island without opposition. At 09:00, after an unnecessary two-hour bombardment by cruisers and destroyers, the 19th Regiment landed at Parang without encountering any resistance, followed by most of the 21st Regiment. That afternoon, the 19th Regiment secured the entire Parang area, and the 24th Reconnaissance Troop scouted the shores of Polloc Harbor and the northern entrance of the Mindanao River, finding them clear.
On April 18, Sibert launched an assault towards Fort Pikit, with the 19th Regiment advancing along Route 1 and the 21st Regiment utilizing the Mindanao River. The 21st's advance was quicker, successfully reaching Paidu-Pulangi the next day. However, the 19th Regiment lagged due to poor road conditions and some enemy resistance, leading Woodruff to order the 21st to withdraw downstream for the night. On April 21, a battalion from the 34th Regiment arrived at Paidu-Pulangi, advancing both overland and along the river to reach Fort Pikit late in the afternoon. The isolated 166th Independent Battalion was ultimately destroyed, with the 19th finally arriving at Fort Pikit on April 23. Meanwhile, the 34th continued to push forward and secured the Kabacan junction of Route 1 and Sayre Highway. This quick capture of the junction effectively separated the 30th and 100th Divisions and opened two routes of attack: north along the Sayre and southeast towards Davao.
Consequently, the newly arrived 31st Division was tasked with sending its 124th Regiment to assault the 30th Division's forces in northern Mindanao, while the 34th Regiment continued its advance along Route 1 towards Digos and Davao. In response, Morozumi dispatched reinforcements under Colonel Ouchi Koretake to block any enemy progress past Omonay, while fortifying the Malaybalay area. By this time, General Morozumi had swung into action in an attempt to stem the enemy advance before it moved north into central Mindanao. Colonel Ouchi, commander of the 30th Engineer Regiment, was ordered about April 22 to take command of operations along the southern approaches and to annihilate the enemy south of the east-west line running through Omonay. For this mission he was given command of the South Sector Unit, as well as his engineer units. On April 23, General Tomochika, Chief of Staff of 35th Army, arrived at the 30th Division command post at Impalutao from Agusan, where he had arrived on April 21 from Cebu. Tomochika immediately conferred with Morozumi regarding implementation of the Army policy of protracted resistance. As a result of this discussion, Morozumi concluded that it was necessary to strengthen the Malaybalay area. He therefore ordered the transfer of the 1st Battalion, 77th Regiment from the North Sector Unit to the Central Sector Unit and the movement of this battalion to new positions near Malaybalay. About the same date Morozumi ordered the Surigao Sector Unit to move from Ampayon to the Waloe area, where it was to assist in carrying out the division's self-sufficiency program. Although the 30th Division commander thus adopted measures to strengthen the area of final resistance, he still considered the landing near Parang a secondary invasion and estimated that the main enemy landing would soon be launched in the Macajalar Bay area. The preponderance of division strength was therefore retained in the north.
Led by the 24th Reconnaissance Troop, the 34th Regiment quickly departed from Kabacan on April 24. Although progress was hampered primarily by destroyed bridges and the poor condition of Route 1, the troops successfully arrived at the outskirts of Digos by April 27, where they faced approximately 3,350 enemy troops. The Japanese forces urgently prepared to defend against the 24th Division's assault but could only hold out until the early hours of April 28, when they retreated to the foothills of Mount Apo to the north. Elements of the 34th Regiment pursued the withdrawing Japanese, who maintained their position in the Mount Apo region until May 9, when they retreated north to regroup with the rest of the 100th Division. Meanwhile, other units of the 34th and the guerrilla 108th Division began patrolling the Davao Gulf coast, which they successfully cleared by May 12. Additionally, the 19th Regiment advanced from Kabacan to Digos, passed through the 34th, and started moving north towards Davao. Facing little resistance along Route 1, the 19th Regiment overwhelmed the last opposition in front of the city and successfully occupied Davao by May 3 with minimal opposition. Meanwhile, on the afternoon of April 27, the 124th Regiment departed from Kabacan and quickly confronted the 1st Battalion, 74th Regiment, causing it to retreat in disarray. The 124th then pressed on to the north, facing minimal resistance, and ultimately arrived in Kibawe by May 3.

The US invasion of Mindanao commenced under General Eichelberger. The initial assault targeted Illana Bay, with American forces quickly securing key areas. Japanese troops, suffering from low morale and inadequate supplies, struggled to mount an effective defense. The campaign marked a pivotal advance in the Pacific War, laying groundwork for further operations.
