Air Operations, Europe

• 38 Lancasters of Nos. 9 and 617 Squadrons and a No. 5 Group Mosquito for weather reconnaissance had set out on September 11 to fly to Northern Russia in preparation for this raid on the 45,000-ton battleship Tirpitz, which is at anchor in Kaa Fjord in Northern Norway. 1 aircraft returns to Britain and 6 crash-land in Russia but their crew members are not seriously hurt. Only 27 Lancasters and a further Lancaster with a cameraman on board are available for the raid on the Tirpitz, which eventually takes place this day. 20 aircraft are loaded with the 12,000-pound Tallboy bomb and 6 (or 7, the records are not clear) carry several 'Johnny Walker' mines - of 400-500-pound weight developed for attacking capital ships moored in shallow water. The attack catches the Tirpitz by surprise and her smoke-screens are late in starting. One Tallboy hits the Tirpitz near the bow and causes considerable damage. The shock caused by the explosion of this bomb, or possibly from other bombs which are near misses, also damage the battleship's engines. The Germans decide that repairs to make Tirpitz fully seaworthy are not practicable and she will be later moved to an anchorage further south in Norway, but only for use as a semi-static heavy artillery battery. These results of the raid are not known in England at the time and further raids against Tirpitz will take place.
• None of the Lancasters are shot down on the raid and all return safely to the airfield in Russia but the No. 617 Squadron aircraft of Flying Officer F. Levy crashes in Norway while returning to Lossiemouth 2 days later with 11 men on board.

• There are 9 RCM sorties and 1 aircraft on a Resistance operation.
• There are no losses.

• 490 aircraft are sent to Kiel. In this total are 310 Lancasters, 173 Halifaxes and 7 Mosquitos of Nos. 1, 4, 6 and 8 Groups. The evidence of returning crews and of photographs cause Bomber Command to record this as 'a highly concentrated raid' with 'the old town and modern shopping center devastated'.
• 4 Halifaxes and 2 Lancasters are lost.

• Support and 164 aircraft make a diversionary sweep over the North Sea, 27 Mosquitos are sent to Berlin, 9 to Lübeck and 8 to Rheine airfield, 68 Halifaxes and Lancasters lay mines near Oslo, the Kattegat and in the Elbe River, and there are 56 Mosquito patrols and 34 RCM sorties.
• 4 Mosquitos and 1 Stirling are lost on the operations.

Allied Planning

The Joint Chiefs of Staff, examining the situation in the Pacific in the light of the limited resistance by the Japanese in the central Philippines, decide to bring forward the invasion fo Leyte from December 20 to October 20, and to cancel the planned operations against the islands of Yap, east of the Palaus, Talaud, south of Mindanao, and Mindanao in the southern Philippines.

Moluccan Islands

American forces land at 8:30a.m. on the southwest of Morotai at the Gila Peninsula. There is no Japanese resistance but the conditions of the terrain are terrible. The landing force is from Charles P. Hall's XI Corps and includes the 31st Div under Gen John C. Persons and an additional regt. The landing has been preceded by an intense 2-hour naval bombardment. The naval support is commanded by Adm Daniel E. Barbey and includes 6 escort carriers as well as cruisers and destroyers. Gen MacArthur is present. Within the day the division occupies the whole of Gila peninsula. On the first day 19,960 men go ashore and by the start of Oct the force has been built up by 26,000 combat troops and 12,200 in the construction units. Airfields are quickly built and until they become operational 5th Air Force gives cover.

Palaus

At 8:30a.m. the US 1st Marine Div, under the command of Gen William H. Rupertus from Roy Geiger's III Amphibious Corps, lands on the southwest coast of Peleliu Island, in the Palau group east of the Philippines. The Japanese garrison of the island is made up of a regt of the 14th Div commanded by Col Kunio Nakagawa. The main Japanese force in the area is on Babelthaup. The naval forces which carried out the preliminary bombardment remain in support.

The landings meet fairly moderate resistance on the beaches but as soon as they move inland the fighting becomes very fierce. The Japanese have constructed a formidable defense system based principally on the complex of caves with which the island is riddled. At the end of the day the perimeter of the beachhead measures a mile and a half from north to south but is only a few hundred yards wide at the most.

The Palau Islands, which have been made into a strategic center for the concentration of Japanese air and naval forces since the destruction of Truk, are defended by over 30,000 soldiers, crack troops under the command of Gen Sadao Inoue. The Japanese have 20,000 men on Babelhuap, the biggest of the islands, 11,000 men on Peleliu and 1,400 men on Angaur, an islet about 10 miles south of Peleliu. There is an excellent airfield on Peleliu and another on the islet of Ngesebus, joined to Peleliu by a narrow embankment. Peleliu has been strongly fortified, with over 500 strongpoints in caves connected by tunnels.

Pacific

The US submarine Guavina (SS-362) sinks the Japanese transport No. 3 in the Philippines Islands area.

Western Front

The Allied armies enter Germany. From Aachen to Luxembourg, units of the US VII and V Corps have reached the southwestern frontiers of the Reich. Since D-Day June 6, the Allies have landed more than 2,000,000 men in France, 40,000 of whom have fallen in battle. In the same period German losses have been catastrophic, the ranks of the Wehrmacht have been depleted by 700,000.

Apart from a strip of land on the German border, Belgium and Luxembourg are completely liberated. The new front runs from near Ostend to Epinal, west of Colmar, by way of Antwerp, Maastricht, Thionville, Metz and Nancy. The Germans employ Gen Walther Model's Army Group B in the north and Gen Johannes Blaskowitz's Army Group G in the south. The first consists of the 15th Army under Gen Gustof A. von Zangen and the 1st Parachute Army under Gen Kurt Student, stationed in Holland, and Gen Erich Brandenberger's 7th Army defending the German border between the Ruhr and the Saar. The second Group deploys, between Metz and Epinal, Gen Otto von Knobelsdorff's 1st Army and Gen Hasso von Manteuffel's 5th Panzer Army.

The British 2nd Army take a second crossing point over the Meuse-Escaut canal. Maastricht and Eisden are both taken by US 1st Army and Nancy and Epinal by US 3rd Army. The forces moving up from the south of France, Gen Alexander Patch's US 7th Army and Gen Jean de Lattre's French 1st Army come under Gen Eisenhower's command.

German frogmen mount a daring raid on the floodgates at Antwerp and make the port unusable to large vessels for 6 weeks.

A massive wall rises from the water of Peleliu as 8.000 lbs. of tetrytol explode to mark the successful conclusion of a UDT mission and the prelude to assault. The following day our forces swept ashore through the channels cleared by the underwater demolition men and opened the grim battle for the Palaus.

As a rocket-firing LCI lays down a barrage on the already obscured beach on Peleliu, a wave of Alligators (LVTs, or Landing Vehicle Tracked) churn toward the defenses of the strategic island September 15, 1944. The amphibious tanks with turret-housed cannons went in in after heavy air and sea bombardment. Army and Marine assault units stormed ashore on Peleliu on September 15, and it was announced that organized resistance was almost entirely ended on September 27. (AP Photo)
