Allied Command

Gen MacArthur tells the US Chiefs of Staff that he is in a position to launch a big operation against Luzon, in the Philippines, following the advance deadline for the landing on Leyte. He also declares that there will be no point in landing on Formosa once Luzon has been captured.

Eastern Front

The Polish 1st Army is forced to withdraw from its bridgeheads in Warsaw.

The last air drop by Western aircraft to the Home Army in Warsaw takes place.

Italy

In the US 5th Army's IV Corps area, TF 45 extends its positions along the coast to Forte dei Marmi. The 6th RCT, BEF, tries unsuccessfully to take Monte Prano. The reorganized CCA, 1st Armored Division, starts to move into the II Corps zone. Left flank elements of the South African 6th Armored Division reach Serra.

In the II Corps area, the 338th Infantry of the 85th Division seizes Firenzuola. The 339th takes Monte Frena and Monte Coloreta. The 337th is withdrawn to the reserve. The 91st Division, to the west, gets advance elements of the 361st and 363rd Regiments to the Santerno. The 362nd, against rear-guard opposition, clears San Lucia and Monte Gazzaro and enters Futa Pass, but the Germans retain the hill dominating it to the west. On the left flank of the corps, th 133rd Infantry of the 34th Division at last clears Torricella Hill. The 168th is withdrawn from the reserve and enters the line between the 133rd and 135th Regiments. On the right flank of the corps, the 88th Division is commtted through the right flank of the 85th Division and, with the 349th Infantry on the left and the 350th on the right, starts quickly down the Santerno valley toward Imola.

In the British XIII Corps area, the 1st Division is half way between Crespino and Marradi. The 6th Armored Division takes Monte Peschiena.

The British 8th Army pursues the retreating enemy toward the Marecchia. The V Corps finds the Ceriano ridge abandoned and gets patrols to the river before dawn of the 22nd. The strengths of the 1st Armored and 56th Divisions are so badly depleted that the divisions must be reorganized. The 56th Division is ordered to withdraw from the line on the 22nd.

In the Canadian I Corps area, the British 4th Division gets patrols across the Marecchia during the night. The Canadian 1st Division mops up the San Fortunato position and establishes a bridgehead across the Marecchia west of Rimini. The attached Greek 3rd Mountain Brigade, having cleared the airfield south of Rimini, enters the coastal city, from which the enemy has withdrawn.

Occupied Denmark

Pacific

• The US submarine Haddo (SS-255), while lifeguarding TF-38, sinks the Japanese surveying ship Katsuriki 80 miles southwest of Manila.
• In action off the east coast of Luzon, the US submarine Picuda (SS-382) sinks the Japanese transport Awaji Maru (1948t) and Redfish (SS-395) sinks the transport Mizuho Maru (8506t).

Palaus

The 1st Marines recapture Hills 200 and 210, but an attack to recapture Hill 100 fails. Maj-Gen Roy S. Geiger orders Maj-Gen William H. Rupertus to pull the 1st Marines out of the line. The Umurbrogol Pocket has nearly destroyed the regiment. The 321st Infantry Regiment of the 81st Infantry Division is to arrive as reinforcement. The 1st Marines have by now loast 1,749 men and have captured 10 coral ridges, 22 pillboxes, 3 blockhouses, 13 anti-tank guns, and have cleared 144 defended caves. The Umurbrogol has been hardly touched. The 7th Marines attack into the area called Wildcat Bowl toward Hill 140.

Elements of the 322nd Infantry break into the Lake Salome bowl on northwestern Angaur but pull back for the night since their positions are untenable. The attack is preceded by a heavy volume of artillery fire and a bombardment of the position by naval planes. The 321st is alerted for movement to Peleliu so that the 1st Marines can be withdrawn from there. The 322nd Infantry now becomes responsible for south Angaur as well as the stubborn pocket on the northeastern end.

The 323rd RCT, III Amphibious Corps reserve, leaves the Palaus for Ulithi.

Philippines

Over the next 4 days 12 carriers from Vice-Adm Mitscher's TF 38 attack targets on Luzon, especially near Manila and in Manila Bay on September 21 and 22. On the 23rd there are no attacks, but on Sept 24 the Visayan islands are hit once again. Japanese ships sunk in the day's operations include the destroyer Satsuki, the tanker Sunosaki, the surveying ship Katsuriki by the submarine Haddo (SS-255), the coast defense vessel No. 5, the auxiliary submarine chaser No. 39 and the minesweeper No. 7. In the operations since August 31 TF 38 had destroyed at least 1,000 Japanese aircraft and sunk 150 ships of all types. The Americans have lost 72 aircraft which includes 18 in accidents.

Southwest Pacific

Based on the approval of the JCS for the invasion of Leyte on October 20, SWPA headquarters orders 6th Army to seize and secure Dinagat and Homonhon Islands as a preliminary action to bringing a landing force into Leyte Gulf. Upon landing, Krueger's 6th Army will have 60 days to defeat enemy forces and establish airbases necessary for future operations. The 8th Army (to be established on September 25 under Lt-Gen Robert L. Eichelberger) will take over all former 6th Army missions in New Guinea, New Britain, the Admiralties, and Morotai. The Australian 1st Army will take the combat missions of XIV Corps in the Solomon s and 6th Army in New Guinea. Gen Kenney's Far East Air Force will attack targets on Mindanao and in the Netherlands East Indies from bases in New Guinea and Morotai.

Western Front

The British XXX Corps continues to attack northward from Nijmegen but can only make very slow progress because the advance must go along or very near to the roads and rail lines which are raised above the marshy surrounding ground and consequently exposed. It is, therefore, comparatively simple to meet these attacks. The British paratroopers have been driven out of Arnhem and are now holding a permiter west of the town but still north of the Rhine. A Polish Parachute Bde or 750 men is dropped 2 miles south of this position on the opposite side of the river.[WE]

Yugoslavia, Politics

The partisan chief Marshal Tito meets the Soviet leader Joseph Stalin. They reach agreement on the 'temporary entry of the Red Army into Yugoslavia.'
