Last time we spoke about the battle of Manila. In early February, General Iwanaka's 2nd Tank Division faced encirclement as American forces advanced. General Griswold's 14th Corps captured Clark Field, while the 8th Cavalry liberated 4,000 internees at Santo Tomas University. Amid fierce fighting, Japanese defenses crumbled, and by February 9, American troops secured key districts in Manila. Despite heavy resistance, they pressed on, clearing areas and establishing a foothold across the Pasig River. In the wake of Pearl Ridge's capture, Australian brigades advanced through Bougainville, engaging Japanese forces along the Jaba and Tavera rivers. Brigadier Monaghan's troops secured strategic positions, while the 2/8th Commandos aided local guerrillas. In January, significant battles unfolded at Tsimba Ridge, where fierce resistance led to an encirclement of Japanese troops. Meanwhile, in Burma, Allied forces executed deceptive maneuvers and launched offensives, as General Aung San’s Burma National Army prepared to switch sides, signaling a shift in the war's momentum.

As we previously noted, General Griswold had three divisions stationed in Manila, which had achieved significant advancements by February 10. Estimating the strength of the Americans in the Manila area at little more than a regiment, General Yokoyama apparently felt that he had a good opportunity to cut off and isolate the Allied force. Conversely, he was also interested in getting the Manila Naval Defense Force out of the city quickly, either by opening a line of retreat or by having Iwabuchi co-ordinate a breakthrough effort with a Shimbu Group counterattack, scheduled for the night of February 16. Not knowing how far the situation in Manila had deteriorated--communications were faulty and Admiral Iwabuchi had supplied Yokoyama with little information--Yokoyama at first directed the Manila Naval Defense Force to hold fast. The question of a general withdrawal, he told Iwabuchi, would be held in abeyance pending the outcome of the counterattack. There is no indication that the Shimbu Group commander intended to reinforce or retake Manila. Rather, his primary interest was to gain time for the Shimbu Group to strengthen its defenses north and northeast of the city and to move more supplies out of the city to its mountain strongholds, simultaneously creating a good opportunity for the Manila Naval Defense Force to withdraw intact. However, the commander of the Shimbu Group was simultaneously orchestrating a large-scale, coordinated raid on northern Manila, intending to weaken the enemy's offensive capability by targeting their vulnerable eastern flank before they could solidify their positions. Therefore, on the night of February 16, the majority of the 31st Regiment was set to assault Caloocan Airfield, while three provisional battalions of the Kobayashi Force would attack Quezon, Banlat Airfield, and the surrounding areas of Rosario. This meant that Iwabuchi’s forces would need to withstand the unyielding American assaults for another week before receiving support. Meanwhile, Griswold was strategizing to cut off the last remaining routes for withdrawal and reinforcement available to Iwabuchi. To achieve this, the 5th and 8th Cavalry Regiments were tasked with advancing southwest toward Manila Bay to make contact with the 11th Airborne Division, effectively encircling the city. Thus, Griswold continued his offensive on February 11, with Company E of the 129th Regiment successfully clearing Provisor Island without resistance and further establishing a presence on the mainland, west across Estero Provisor. Other elements of the 37th Division were gradually advancing across the Estero de Paco despite heavy enemy fire, while the 5th Cavalry made limited progress at Nielson Field. The 8th Cavalry pushed nearly to the Estero de Paco along the division boundary against scattered opposition, the 511th Parachute Regiment advanced north toward Libertad Avenue, and the 187th Glider Regiment secured the southeast corner and southern runway of Nichols Field. The next day, to complete the encirclement of Manila, the 5th Cavalry swiftly advanced across Nielson Field, facing sporadic rifle fire, and successfully connected with the 511th at Libertad Avenue before reaching the shores of Manila Bay. Simultaneously, the 12th Cavalry Regiment relieved the 8th and rapidly moved westward to establish contact with the 5th at Villarruel Street. Further south, following intense artillery and air bombardment, the 187th and 188th Glider Regiments finally breached the Japanese defenses at Nichols Field. The attack was preceded by artillery and mortar concentrations and by an air strike executed by Marine Corps SBD's from the Lingayen Gulf fields, support that succeeded in knocking out many Japanese artillery positions. The 2d Battalion, 187th Infantry, attacked generally east from the northwest corner of the field; the 188th Infantry and the 1st Battalion, 187th Infantry, drove in from the south and southeast. By dusk the two regiments had cleared most of the field and finished mopping up the next day. The field was, however, by no means ready to receive Allied Air Force planes. Runways and taxiways were heavily mined, the runways were pitted by air and artillery bombardments, and the field was still subjected to intermittent artillery and mortar fire from the Fort McKinley area. With the seizure of Nichols Field, the 11th Airborne Division substantially completed its share in the battle for Manila. Since its landing at Nasugbu the division had suffered over 900 casualties. Of this number the 511th Infantry lost approximately 70 men killed and 240 wounded; the 187th and 188th Infantry Regiments had together lost about 100 men killed and 510 wounded, the vast majority in the action at Nichols Field. The division and its air and artillery support had killed perhaps 3,000 Japanese in the metropolitan area, destroying the 3d Naval Battalion and isolating the Abe Battalion. From then on the division's activities in the Manila area would be directed toward securing the Cavite region, destroying the Abe Battalion, and, in co-operation with the 1st Cavalry Division, assuring the severance of the Manila Naval Defense Force's routes of escape and reinforcement by clearing Fort McKinley and environs. Meanwhile, at ZigZag Pass, General Chase’s 38th Division had begun to make headway against the strong defenses of the Nagayoshi Detachment, with the 152nd and 149th Regiments set to launch a coordinated attack from the east and west on February 12. It wasn't until the afternoon of February 13 that the 149th and 152nd made their first brief contact from their respective sides of ZigZag. The 149th then captured the last organized Japanese stronghold on February 14, and the following day both regiments completed their mopping-up operations. Nearly 2,400 Japanese soldiers were killed at the pass during this battle, though about 300 men under Colonel Nagayoshi managed to escape south into Bataan. The 38th Division and the 34th Regiment, in turn, suffered around 1,400 casualties, including 250 killed. Meanwhile, General Brush’s 40th Division continued its offensive against the Kembu Group. By February 12, the 185th Regiment had successfully secured Snake Hill North with minimal resistance, while also capturing Hills 810 and 1000. Meanwhile, the 160th Regiment made significant advances against Snake Hill West and Scattered Trees Ridge. The 108th Regiment, after neutralizing the Japanese strongholds on the hill, began attacking the remnants of the Eguchi and Yanagimoto Detachments at Hill 7. On February 15, the 185th captured Hill 1500, coinciding with the 160th clearing Snake Hill West and preparing to advance toward Object Hill. The next day, Hill 7 fell to the 108th, while the 160th reached the summit of Object Hill and broke through Scattered Trees Ridge. By February 20, the 160th had cleared the rest of Object Hill and established a foothold on Sacobia Ridge. Whatever the costs, the 40th Division's advances to February 20 marked the end of the Kembu Group as a threat to 6th Army and 14th Corps. Clark Field, Route 3, and the army and corps right were now secure beyond all shadow of doubt. The Kembu Group had defended its ground well since January 24, when 14th Corps had first gained contact, and had inflicted nearly 1500 casualties upon 14th Corps units--roughly 285 men killed and 1180 wounded--but had itself lost around 10000 men killed. The 20000 troops General Tsukada still commanded were hardly in good shape. Supplies of all kinds were dwindling rapidly, morale was cracking, and centralized control was breaking down. The only defenses still intact were those held by the naval 13th and 17th Combat Sectors, and those had been heavily damaged by air and artillery bombardments. Troops of the 6th Army would continue to fight the Kembu Group, but after February 20 operations in the Kembu area were essentially mop-ups. 11th Corps, not 14th, would be in charge of the final mop-up operations in the Kembu area. Under General Hall’s leadership, the 40th Division resumed the mop-up operation on February 23, but was replaced by elements of the 43rd Division just five days later. In the following ten days, this division would ultimately eliminate General Tsukada’s last defensive position, pushing the Kembu Group further into the Zambales Range. Back in Manila, on February 13, chaos erupted as Iwabuchi’s forces prepared for their final stand in the Filipino capital. After February 12th the 14th Corps troops found themselves in a steady war of attrition. Street-to-street, building-to-building, and room-to-room fighting characterized each day's activity. Progress was sometimes measured only in feet; many days saw no progress at all. The fighting became really "dirty." The Japanese, looking forward only to death, started committing all sorts of excesses, both against the city itself and against Filipinos unlucky enough to remain under Japanese control. As time went on, Japanese command disintegrated. Then, viciousness became uncontrolled and uncontrollable; horror mounted upon horror. The men of the 37th Division and the 1st Cavalry Division witnessed the rape, sack, pillage, and destruction of a large part of Manila and became reluctant parties to much of the destruction. Although the 14th Corps placed heavy dependence upon artillery, tank, tank destroyer, mortar, and bazooka fire for all advances, cleaning out individual buildings ultimately fell to individual riflemen. To accomplish this work, the infantry brought to fruition a system initiated north of the Pasig River. Small units worked their way from one building to the next, usually trying to secure the roof and top floor first, often by coming through the upper floors of an adjoining structure. Using stairways as axes of advance, lines of supply, and routes of evacuation, troops then began working their way down through the building. For the most part, squads broke up into small assault teams, one holding entrances and perhaps the ground floor--when that was where entrance had been gained--while the other fought through the building. In many cases, where the Japanese blocked stairways and corridors, the American troops found it necessary to chop or blow holes through walls and floors. Under such circumstances, hand grenades, flame throwers, and demolitions usually proved requisites to progress. In response to the encirclement of Manila, Yokoyama concluded that the situation in the city was irreparable and ordered Iwabuchi to relocate to Fort McKinley and begin withdrawing his troops immediately, without waiting for the Shimbu Group's counterattack. However, Iwabuchi did not receive this order until two days later, by which time he and his troops were determined to fight to the death, taking as many enemies with them as possible. The 129th Regiment made an unsuccessful attempt to assault the New Police Station and the Manila Club. Meanwhile, the 148th Regiment reached Taft Avenue but could not launch an attack on the Philippine General Hospital and the University of the Philippines. The 5th and 12th Cavalry Regiments turned north, taking two days to fight through the Pasay suburb to Vito Cruz Street. On February 14, although the 148th Regiment struggled to make any headway against Iwabuchi’s strong defenses, the 129th, supported by tanks, managed to break through to the Manila Club and the New Police Station. However, the Japanese quickly regrouped at the latter location and began throwing hand grenades from the second floor, forcing the Americans to retreat. Simultaneously, a battalion-sized guerrilla force led by Major John Vanderpool was dispatched to contain the Abe Provisional Battalion at Mabato Point, while elements of the 11th Airborne Division and the 1st Cavalry Division began clearing the routes to Fort McKinley. On February 15 and 16, the 129th conducted probing attacks on the New Police Station, the shoe factory, and Santa Teresita College, while tanks and artillery maintained consistent fire on all buildings still held by the Japanese. The 3rd Battalion of the 148th Regiment reached Manila Bay via Herran Street and then turned to assault the hospital from the south, while the 2nd Battalion made limited progress against the main hospital structures. The 12th Cavalry successfully entered La Salle University and the Japanese Club, and the 5th Cavalry pushed through Harrison Park, clearing Rizal Stadium, with the entire area being secured by February 18. In the early hours of February 16, Yokoyama initiated his limited offensive, with the 31st Regiment advancing toward Novaliches while General Kobayashi’s three battalions attacked Marikina.The 112th Cavalry RCT, which had replaced the 12th Cavalry along the 1st Cavalry Division's line of communications, broke up the northern wing's counterattack between 15 and 18 February. In the Novaliches-Novaliches Dam area, and in a series of skirmishes further west and northwest, the 112th Cavalry RCT dispatched some 300 Japanese, losing only 2 men killed and 32 wounded. Un-co-ordinated from the start, the northern counterattack turned into a shambles, and the northern attack force withdrew in a disorganized manner before it accomplished anything. The Kobayashi Force's effort was turned back on the morning of the 16th, when American artillery caught this southern wing as it attempted to cross the Marikina River. During the next three days all Japanese attacks were piecemeal in nature and were thrown back with little difficulty by the 7th and 8th Cavalry Regiments, operating east and northeast of Manila. By 19 February, when the southern counterattack force also withdrew, the 2d Cavalry Brigade and support artillery had killed about 650 Japanese in the area west of the Marikina from Novaliches Dam south to the Pasig. The brigade lost about 15 men killed and 50 wounded. Consequently, Yokoyama's only achievement was the escape of the remnants of the 3rd and 4th Naval Battalions…
