Battle of Leyte
The Battle of Leyte in the Pacific campaign of World War II was the invasion and conquest of Leyte in the Philippines by the United States and Australian forces and allied Filipino guerrillas under the command of General Douglas MacArthur and waged against the Imperial Japanese Army in the Philippines led by General Tomoyuki Yamashita from 17 October 1944 to 31 July 1945. The battle launched the Philippines campaign of 1944-45 for the recapture and liberation of the entire Philippine Archipelago and to end almost three years of Japanese occupation.
For the Japanese, holding on to the Philippines was vital. As an important source of supplies, especially rubber, it also commanded the sea routes to Borneo and Sumatra by which oil was brought to Japan. For the Americans, it was a key strategic step in isolating Imperial Japan's military holdings in China and the Pacific theater. It was also a personal matter for MacArthur: two years previously he had left the Philippines vowing to return and insisted that it was a moral obligation of the U.S. to liberate its citizens as soon as possible.
In September up to early October 1944, successful Allied fleet coverage by aircraft from carrier task forces of the U.S. Third Fleet under Admiral William F. Halsey during the Palau and Morotai campaigns which destroyed some 500 enemy aircraft and 180 seagoing merchant shipping in the Philippines, Okinawa, and Formosa, subsequently proved an invasion of the Philippines was more feasible.
Leyte, one of the larger Philippine islands has numerous deep-water approaches and sandy beaches which offered opportunities for amphibious assaults and fast resupply operations. The roads and lowlands extending inland from Highway 1, which ran for forty miles along the east coast between the Abuyog town up north to San Juanico Strait between Leyte and Samar Islands, provided avenues for tank-infantry operations, as well as a basis for airfield construction. American air forces based on Leyte could strike on enemy bases and airfields anywhere in the archipelago.
A heavily-forested north-south mountain range dominated the interior which separated two sizable valleys, or coastal plains. The larger Leyte Valley extended from the northern coast to the long eastern shore and contained most of the towns and roadways on the island. The other, Ormoc Valley, situated on the west side, was connected to Leyte Valley by a roundabout and winding road, Highway 2, which ran from Palo town on the east coast, then west and northwest through Leyte Valley to the north coast, then turned south and wound through a mountainous neck to enter northern Ormoc Valley. This continued south to the port of Ormoc City, then along the western shore to Baybay town. The road then turned east to cross the mountainous waist of the island and connected with Highway 1 on the east coast at Abuyog. Below these towns, the mountainous southern third of Leyte was sparsely and remained largely undeveloped. High mountain peaks over 4,400 feet, as well as the jagged outcroppings, ravines, and caves typical of volcanic islands, offered formidable defensive opportunities. In addition, the late-year schedule of the assault would force combat troops and supporting pilots, as well as logistical units, to contend with monsoon rains.
Leyte's population of over 900,000 people, most of whom engaged in agriculture and fishing, could be expected to assist an American invasion since many residents already supported the guerrilla struggle against the Japanese in the face of harsh repression. Japanese troop strength on Leyte was estimated by U.S. intelligence at 20,000, most of the 16th Division under Lt. Gen. Shiro Makino.
The Landing Forces
The Leyte invasion was the largest amphibious operation mounted by American and Allied forces to date in the Pacific theater. Gen. MacArthur was designated as supreme commander of sea, air, and land forces drawn from both the Southwest and Central Pacific theaters of operation. Allied naval and air support forces consisted primarily of the U.S. Seventh Fleet under Vice Adm. Thomas C. Kinkaid. With 701 ships, including 157 warships, Kinkaid's fleet would transport and put ashore the landing force. The Royal Australian Navy forces seconded to the Seventh Fleet included five warships, three landing ships, and five auxiliary vessels.
The U.S. Sixth Army under Lt. Gen. Walter Krueger was the main combat force, which consisted of two corps of two divisions each. Maj. Gen. Franklin C. Sibert's X Corps included the 1st Cavalry Division and the 24th Infantry Division, minus the 21st RCT. Maj. Gen. John R. Hodge's XXIV Corps included the 7th Infantry Division and the untested 96th Infantry Division. The 32nd and 77th Infantry Divisions and the 381st RCT (of the 96th) were the reserve forces. Supplementary units included the 6th Ranger Battalion, tasked to secure outlying islands and guide naval forces to the landing beaches. The new 6th Army Service Command under Maj. Gen. Hugh J. Casey, was responsible for organizing the beachhead supplying units ashore and constructing or improving roads and airfields. In all, Gen. Krueger had under his command a total of 202,500 ground troops. On Leyte, some 3,000 Filipino guerrillas under Lt. Col. Ruperto Kangleon await the landing forces.
The Sixth Army mission of securing Leyte was to be accomplished in three phases. The first would begin on 17 October, three days before and some fifty miles east of the landing beaches, with the seizure of three islands commanding the eastern approaches to Leyte Gulf. On A-Day, 20 October, the X and XXIV Corps would land at separate beaches on the east coast of Leyte, the former on the right (north), the latter fifteen miles south. The X Corps would take Tacloban City and its airfield, north of the corps beachhead, secure the strait between Leyte and Samar Islands, then push through Leyte Valley to the north coast. The XXIV Corps was to secure southern Leyte Valley for the airfield and logistical development. Meanwhile, the 21st RCT would come ashore to secure the strait between Leyte and Panaon Islands. In the third phase, the two corps would take separate routes through the mountains to clear the enemy from Ormoc Valley and the west coast of the island at the same time placing an outpost on the island of Samar some thirty-five miles north of Tacloban.
Preliminary operations for the Leyte invasion began at dawn on 17 October with minesweeping operations and the movement of the 6th Rangers toward three small islands in Leyte Gulf. Although delayed by a storm, the Rangers were on Suluan and Dinagat islands by 1230. On Suluan, they dispersed a small group of Japanese defenders and destroyed a radio station, while they found Dinagat unoccupied. On both, the Rangers proceeded to erect navigation lights for the amphibious transports to follow three days later. The next day, the third island Homonhon was held without opposition. Meanwhile, reconnaissance by underwater demolition teams revealed clear landing beaches for assault troops on Leyte itself.
Following four hours of heavy naval gunfire on A-day, 20 October, Sixth Army forces landed on assigned beaches at 1000 hours. The X Corps pushed across a four-mile stretch of beach between Tacloban airfield and the Palo River. Fifteen miles to the south, XXIV Corps units came ashore across a three-mile strand between San José and the Daguitan River. Troops found as much or more resistance from swampy terrain as from Japanese fire. Within an hour of landing, units in most sectors had secured beachheads deep enough to receive heavy vehicles and large amounts of supplies. Only in the 24th Division sector did enemy fire force a diversion of follow-on landing craft. But even that sector was secure enough by 1330 to allow Gen. MacArthur to make a dramatic entrance through the surf and announce to the populace the beginning of their liberation: "People of the Philippines, I have returned! By the grace of Almighty God, our forces stand again on Philippine soil."
By the end of A-day, the Sixth Army had moved inland as deep as two miles and controlled Panaon Strait at the southern end of Leyte. In the X Corps sector, the 1st Cavalry Division held Tacloban airfield and the 24th Infantry Division had taken the high ground commanding its beachheads Hill 522. In the XXIV Corps sector, the 96th Infantry Division held the approaches to Catmon Hill. The 7th Infantry Division took the town of Dulag, which forced Gen. Makino to move his command post ten miles inland to the town of Dagami. The initial fighting was won at a cost of 49 killed 192 wounded and 6 missings.
Campaign in Southern Leyte Valley
The Sixth Army made steady progress inland against sporadic and uncoordinated enemy resistance on Leyte in the next few days. The 1st Cavalry Division of Maj. Gen. Verne D. Mudge, secured the provincial capital, Tacloban on 21 October. On 23 October, Gen. MacArthur presided over a ceremony to restore civil government to Leyte. 1st and 2nd Cavalry Brigades initiated a holding action to prevent a Japanese counterattack from the mountainous interior, after which the 1st Cavalry was allowed to move out.
On the X Corps left, the 24th Infantry Division under Maj. Gen. Frederick A. Irving, drove inland into heavy enemy resistance and after days and nights of hard fighting and killing some 800 Japanese, the 19th and 34th Infantry Regiments expanded their beachhead and took control of high ground commanding the entrance to the northern Leyte Valley. By 1 November, after a seven-day tank-infantry advance supported by artillery fire, both regiments had pushed through Leyte Valley and were within sight of the north coast and the port of Carigara. The next day, the 2nd Cavalry Brigade captured Carigara. In its drive-through Leyte Valley, the 24th Division inflicted nearly 3,000 enemy casualties. These advances left only one major port on Leyte- Ormoc City on the west coast-under Japanese control.
From the XXIV Corps beachhead, Gen. Hodge had sent his two divisions into the southern Leyte Valley, which already contained four airfields and a large supply center. Maj. Gen. James L. Bradley's 96th Infantry Division was to clear Catmon Hill, a 1,400-foot promontory, the highest point in both corps beachheads, and used by the Japanese as an observation and firing post to fire on landing craft approaching the beach on A-day. Undercover of an incessant artillery and naval gunfire, Bradley's troops made their way through the swamps south and west of the high ground at Labiranan Head. After a three-day fight, on 28 October, the 382nd Infantry took a key Japanese supply base at Tabontabon, five miles inland, and killed some 350 Japanese. Simultaneously, two battalions each from the 381st and 383d Infantry Regiments slowly advanced up opposite sides of Catmon Hill, battled the fierce Japanese resistance and when the mop-up of Catmon Hill was completed on 31 October, the Americans had cleared fifty-three pillboxes, seventeen caves, and several heavy artillery positions.
On the XXIV Corps left, the 7th Infantry Division under Maj. Gen. Archibald V. Arnold, moved inland, with four Japanese airfields between the small towns of Dulag and Burauen as the objective. On 21 October, the 184th Infantry took Dulag airfield, while the 32nd Infantry cleared both sides of the Calbasag River. The bloody fight for the airfields and village was decided by flying wedges of American tanks cleared the way for the infantrymen. At Burauen, the 17th Infantry overcame fanatical but futile resistance from enemy spider holes and suicidal attacks to stop the American tanks by holding explosives against their armored hulls. A mile north, 32nd Infantry soldiers killed more than 400 Japanese at Buri airfield. While two battalions of the 184th Infantry patrolled the corps left flank, the 17th Infantry with the 184th's 2nd Battalion attached, turned north toward Dagami, six miles above Burauen. Using flamethrowers to root their enemy out of pillboxes and a cemetery, U.S. troops captured Dagami on 30 October, which forced Gen. Makino to evacuate his command post further westward. Meanwhile, on 29 October, the 32nd Infantry's 2nd Battalion, preceded by the 7th Cavalry Reconnaissance Troop, moved fifteen miles south along the east coast to Abuyog for a probe of the area, and then over the next four days, patrolled west through the mountains to bring Ormoc Bay under observation, all without opposition.
As the Sixth Army pushed deeper into Leyte, the Japanese struck back in the air and at sea. On 24 October, some 150 to 200 enemy aircraft approached American beachheads and shipping from the north. Fifty American land-based aircraft rose to intercept, claiming to have shot down somewhere between sixty-six and eighty-four of the attackers. Nevertheless, day and night air raids continued over the next four days, damaging supply dumps ashore and threatening American shipping. But by 28 October, counterattacks by U.S. aircraft on Japanese airfields and shipping on other islands so reduced enemy air strength that conventional air raids ceased to be a major threat. As their air strength diminished, the Japanese resorted to the deadly kamikazes, a corps of pilots willing to crash their bomb-laden planes directly into U.S. ships, committing suicide in the process. They chose the large American transport and escort fleet that had gathered in Leyte Gulf on A-day as their first target and sank only one escort carrier and heavily damaged many other vessels.
A more serious danger to the U.S. forces developed at sea. To destroy U.S. Navy forces supporting the Sixth Army, the Imperial Japanese Navy decided to commit nearly its entire surface fleet to the Leyte Campaign in three major task groups. One, which included four aircraft carriers with no aircraft aboard, was to act as a decoy, luring the U.S. Third Fleet north away from Leyte Gulf. If the decoy was successful, the other two groups, consisting primarily of heavy surface combatants, would enter the gulf from the west and attack the American transports.
On 23 October 1944, the approach of the enemy surface vessels was revealed and as U.S. naval units moved out to intercept, the ensuing air and naval battle on 23-26 October 1944 known as the Battle of Leyte Gulf represented the largest naval battle in the Pacific. By 11 December, nonetheless, the Japanese had succeeded in moving to Leyte more than 34,000 troops and over 10,000 tons of materiel, most of it through the port of Ormoc on the west coast, despite heavy losses on reinforcement convoys, including engagements at Ormoc Bay due to relentless air interdiction missions by U.S. aircraft.
Advance into Northern Leyte Valley
The Japanese reinforcement presented severe problems for both Krueger and MacArthur. Instead of projected mopping up operations after clearing the east side of Leyte, the Sixth Army now had to prepare for extended combat in the mountains on its western side, which included landing three reserve divisions on Leyte, which pushed back Gen. MacArthur's operations schedule for the Philippine campaign and the War Department's deployment plans in the Pacific.
The ground situation though still looked good. The 1st Cavalry and 24th Infantry Divisions linked up at Carigara on 2 November highlighted the successful opening drive of the campaign. After seventeen days of combat operations, the Sixth Army had all of its first and second phase objectives under control, as well as one third-phase objective, Abuyog. In addition, elements of the 7th Division had pushed across the island from the southern end of the XXIV Corps sector and controlled approaches to the town of Baybay on the west coast. Only one key area, Ormoc Valley on the west side of the island, remained to be taken.
To clear Ormoc Valley, Gen. Krueger planned a giant pincer operation, with X Corps forces moving south through the mountains and XXIV Corps units pushing north along the western shore. To overcome the expected increased resistance, especially in the mountain barrier to the north, Krueger mobilized his reserve forces, the 32nd, and 77th Infantry Divisions, while MacArthur activated the U.S. 11th Airborne Division|11th Airborne Division. The 21st RCT pulled out from the Panaon area to rejoin the 24th Division and replaced by a battalion of the 32nd Infantry. On 3 November, the 34th Infantry moved out from the west of Carigara to sweep the rest of the northern coast before turning south into the mountains. The 1st Battalion soon came under attack from a ridge along the highway. Supported by the 63rd Field Artillery Battalion, the unit cleared the ridge, and the 34th Infantry continued unopposed that night through the town of Pinamopoan, recovered numerous heavy weapons abandoned by the enemy, then halted at the point where Highway 2 turns south into the mountains.
Battles of Breakneck and Kilay Ridges
On 7 November the 21st Infantry went into its first sustained combat on Leyte when it moved into the mountains along Highway 2, near Carigara Bay. The fresh regiment, with the 19th Infantry's 3rd Battalion attached, immediately ran into strong defenses of the newly arrived Japanese 1st Division, aligned from east to west across the road and anchored on a network of fighting positions built of heavy logs and interconnecting trench lines and countless spider holes, which became known as "Breakneck Ridge".
A typhoon, which had begun on 8 November, and heavy rains that followed for several days further impeded American progress. Despite the storm and high winds, which added falling trees and mudslides to enemy defenses and delayed supply trains, the 21st Infantry continued its slow and halting attack, with companies often having to withdraw and recapture hills that had been taken earlier. Fortunately, the Americans had seized the approaches to Hill 1525, two miles east enabling Gen. Irving to stretch out the enemy defenses further across a four-mile front along Highway 2.
Five days of battling against seemingly impregnable hill positions and two nights of repulsing enemy counterattacks proved fruitless so Gen. Irving decided on a double envelopment of the enemy defenders. The 19th Infantry's 2nd Battalion swung east around Hill 1525 behind the enemy right flank, cutting back to Highway 2, three miles south of Breakneck Ridge. To take the left flank to the west, Irving sent the 34th Infantry's 1st Battalion under Lt. Col. Thomas E. Clifford, over water from the Carigara area to a point two miles west of the southward turn of Highway 2 and moved it inland. After crossing a ridgeline and the Leyte River, they approached the enemy left flank at 900-foot Kilay Ridge, the highest terrain behind the main battle area. Both battalions reached positions only about 1,000 yards apart on opposite sides of the highway by 13 November despite strong opposition and heavy rains. Clifford's battalion promptly attacked Kilay Ridge on the west, while the 2nd Battalion assaulted a hill on the east side. Neither unit achieved its objectives.
It took Clifford's men two weeks of struggle through mud and rain, often dangerously close to friendly mortar and artillery fire, to root the enemy out of fighting positions on the way up Kilay Ridge. On 2 December Clifford's battalion finally cleared the heights overlooking the road and 32nd Division units quickly took over. Clifford's outfit suffered 26 killed, 101 wounded and 2 missings, in contrast to 900 enemies dead. For their arduous efforts against Kilay Ridge and adjacent areas, both flanking battalions received Presidential Unit Citations. Clifford himself received the Distinguished Service Cross for the action. It was not until 14 December that the 1st Cavalry Division and the 32nd Division finally cleared the Breakneck-Kilay Ridge area, placing the most heavily defended portions of Highway 2 between Carigara Bay and the Ormoc Valley under X Corps control.
Throughout this phase, American efforts had become increasingly hampered by logistical problems. Mountainous terrain and impassable roads forced Sixth Army transportation units to improvise resupply trains of Navy landing craft, tracked landing vehicles, airdrops, artillery tractors, trucks, even carabaos, and hundreds of barefoot Filipino bearers. Not surprisingly, the complex scheduling of this jerry-built system slowed resupply as well as the pace of assaults, particularly in the mountains north and east of Ormoc Valley and subsequently in the ridgelines along Ormoc Bay.
Drive through Ormoc Valley
With the X Corps making headway through the northern mountains, the XXIV Corps struggled to muster forces around Baybay for the northern drive up the western Ormoc Valley coast. By mid-November, the XXIV Corps still had only the 32nd Infantry in western Leyte, with 7th Division remnants still securing Burauen. Only the arrival of the 11th Airborne Division in strength around 22 November finally made Gen. Hodge allow the entire 7th Division to the west. On the night of 23 November, the 32nd Division suddenly came under attack by the Japanese 26th Division with its 2nd Battalion was pushed back, but then regained lost ground the next day. Gen. Arnold ordered his units to dig in and attached the 1st Battalion, 184th Infantry, to the 32nd Infantry, including reinforcements from the 767th Tank Battalion, the 49th Field Artillery Battalion, and a Marine Corps 155-mm. battery from the canceled Yap operation. Pummeled by heavy fire from these artillery units, the Japanese concentrated on them on the night of 24 November and put four 105-mm. pieces out of action. The 57th Field Artillery Battalion reinforced them the next day, giving the 7th Division five additional batteries to support what had now become a major defensive effort. The battle for Shoestring Ridge continued, as the Japanese mounted two more attacks on consecutive nights despite heavy casualties. Not until 27 November were U.S. troops able to take the offensive, with some 500 enemies dead and 29 abandoned machine guns outside and within the defensive perimeter discovered during their northern advance.
Gen. Arnold finally began his advance toward Ormoc with a novel tactic. On the night of 4 December vehicles of the 776th Amphibian Tank Battalion put to sea and leaped-frogged north along the coast 1,000 yards ahead of the ground units. The next morning, the tanks moved to within 200 yards of the shore and fired into the hills in front of the advancing 17th and 184th regiments. This tactic proved effective, greatly disorganizing the defenders, except where ground troops encountered enemy pockets on reverse slopes inland, shielded from the offshore tank fire. The 7th Division pushed north with two regiments that encountered heavy enemy fire coming from Hill 918, from which the entire coast to Ormoc City could be observed. Two days of intense fighting against enemy units enabled the 17th and 184th regiments to clear the strongpoint, after which the advance accelerated. By 12 December, Gen. Arnold's lead battalion was less than ten miles south of Ormoc City.
Fall of Ormoc
While Gen. Arnold moved closer to Ormoc, the Japanese made a surprise attack on the Burauen airfields with the 16th and 26th Divisions in the central mountains, combined with the 3rd and 4th Airborne Raiding Regiments from Luzon. Some 350 Japanese paratroopers dropped at dusk on 6 December, mostly near the San Pablo airstrip. Although poorly coordinated, the enemy attack yielded the seizure of some abandoned weapons which they managed to use against the Americans over the next four days. Hastily mustered groups of support and service troops of the 7th Division held off the Japanese until reinforcements from the 11th Airborne and 38th Infantry Division, concentrated enough strength to contain and defeat the enemy paratroopers by nightfall of 11 December. With a few American supply dumps and aircraft on the ground destroyed and construction projects delayed, the enemy attacks on the airfields failed to have any effect on the overall Leyte Campaign.
Meanwhile, on the west side of Leyte, the XXIV Corps received reinforcements on 7 December with the landing of the 77th Infantry Division under Maj. Gen. Andrew D. Bruce, south of Ormoc City. The 77th Division's 305th, 306th, and 307th Infantry Regiments came ashore unopposed although naval shipping was subjected to kamikaze air attacks. The arrival of the 77th Division proved decisive. This enabled the 7th Division to resume its march north, and the enemy defenders were quickly squeezed between the two forces. Gen. Suzuki ordered the Burauen task force to disengage and cross the mountains to help hold Ormoc Valley. Only small groups of these exhausted and malnourished troops reached the west coast in time to be of any great use.
The 77th Division faced strong opposition at Camp Downes, a prewar Philippine constabulary post. Supported by the 305th and 902d Field Artillery Battalions, Gen. Bruce's troops pushed through and beyond Camp Downes to enter Ormoc City on 10 December 1944 and in its final drive, U.S. troops killed some 1,506 enemies and took 7 prisoners while losing 123 killed wounded and 13 missing. With Ormoc City captured, the XXIV Corps and X Corps were only sixteen miles apart. In between, the last enemy salient with its defenses anchored on a blockhouse, north of Ormoc, and held by the 12th Independent Infantry Regiment, resisted the Americans for two days. On 14 December, the 305th Infantry closed on the stronghold, aided by heavy artillery barrages and employing flamethrowers and armored bulldozers. Hand-to-hand combat and the inspiring leadership of Medal of Honor awardee Capt. Robert B. Nett cleared the enemy from the blockhouse area, while leading Company E, 2nd Battalion, 305th Infantry forward through intense fire and killing several Japanese soldiers himself.
Westward March To The Coast
After breaking out of Ormoc, the 77th Division took Valencia airfield, seven miles north, on 18 December, and continued north to establish contact with X Corps units. That same day, Gen. Sibert ordered the 1st Cavalry Division to complete the drive south. The 12th Cavalry Regiment pushed out of the mountains on a southwest track to Highway 2, then followed fire from the 271st Field Artillery Battalion to clear a three-mile stretch of the road. North of Ormoc Valley, the 32nd Division had met continued determined opposition from the defending Japanese 1st Division along Highway 2, after moving south past Kilay Ridge and entered a heavy rain forest, which limited visibility and concealed the enemy. Using flamethrowers, hand grenades, rifles, and bayonets, troops valiantly scratched out daily advances measured in yards, and in five days of hard fighting, the 126th and 127th Infantry advanced less than a mile. Contact between patrols of the 12th Cavalry and the 77th Division's 306th Infantry on 21 December marked the juncture of the U.S. X and XXIV Corps and the closing of the Sixth Army's pincer maneuver against Ormoc Valley.
While the 77th and 32d Divisions converged on the valley, Maj. Gen. Joseph M. Swing's 11th Airborne Division had moved into the central mountain passes from the east. With blocking positions established south of Leyte Valley on 22-24 November, the 511th Parachute Infantry Regiment pushed farther west into the mountains on 25 November. After an arduous advance, the 511th reached Mahonag, ten miles west of Burauen, on 6 December, the same day Japanese paratroops landed at the Buri and San Pablo airfields. On 16 December, the 2nd Battalion, 32nd Infantry, made slow but steady progress into the mountains from the Ormoc Bay area to meet the airborne regiment and assist its passage westward. On 23 December after battling scattered Japanese defenders on ridges and in caves, the 7th Division infantrymen met troops from the 2nd Battalion, 187th Glider Infantry Regiment, which had passed through the 511th, to complete the cross-island move.
Gen. Bruce opened the drive on Palompon by sending the 2nd and 3rd Battalions, 305th Infantry, with armor support, west along the road on the morning of 22 December. The 302d Engineer Battalion followed repairing and strengthening bridges for armor, artillery, and supply vehicles. Assault units progressed rapidly through sporadic enemy fire until they hit strong positions about eight miles short of Palompon. To restore momentum, Gen. Bruce put the 1st Battalion, 305th Infantry, on Navy landing craft and dispatched it from the port of Ormoc to Palompon. Supported by fire from mortar boats of the 2nd Engineer Special Brigade and from the 155-mm. guns of the 531st Field Artillery Battalion, the infantrymen landed at 0720, 25 December, and secured the small coastal town within four hours.
Learning of the seizure of the last port open to the Japanese, Gen. MacArthur announced the end of organized resistance on Leyte. As these sweeps continued, Gen. MacArthur transferred control of operations on Leyte and Samar to the Eighth Army on 26 December 1944. Farther north, other U.S. forces made faster progress against more disorganized and dispirited enemy troops. 1st Cavalry Division troops reached the coast on 28 December as 24th Division units cleared the last enemy positions from the northwest corner of Leyte on the same day, and after two days later met patrols of the 32nd Division. But Japanese defenders continued to fight as units until 31 December and the ensuing mop-up of stragglers continued until 8 May 1945.
The campaign for Leyte proved the first and most decisive operation in the American reconquest of the Philippines, and cost American forces a total of 15,584 casualties, of which 3,504 were killed in action. Australian casualties included 30 dead and 64 wounded when a Japanese kamikaze plane crashed into the heavy cruiser, HMAS Australia (1927)|HMAS Australia, during the gulf battle.
The Japanese lost an estimated 49,000 combat troops in their failed defense of Leyte. Their losses at Leyte were heavy, with the army losing four divisions and several separate combat units, while the navy lost 26 major warships and 46 large transports and merchantmen in the campaign. The struggle also reduced Japanese land-based air capability in the Philippines by more than fifty percent, forcing them to depend on suicidal kamikaze pilots. Some 250,000 troops still remained on Luzon but the loss of air and naval support at Leyte so narrowed Gen. Yamashita's options that he now had to fight a defensive, almost passive, the battle of attrition on Luzon, clearly the largest and most important island in the Philippines. In effect, once the decisive battle of Leyte was lost, the Japanese themselves gave up all hope of retaining the Philippines, conceding to the Allies in the process a critical bastion from which Japan could be easily cut off from outside resources, and from which the final assaults on the Japanese home islands could be launched.
