Air Operations, Europe

In Operation STEINBOCK (IBEX), also known as the 'Little Blitz' on London, a motley force of 447 aircraft, including He-177 heavy bombers, are sent to bomb London. Only 32 tons of bombs are dropped on target. 9 planes are lost. There will be 13 similar attacks from January 29 to April 18.

• 648 aircraft are sent to Madgeburg. In this total are 421 Lancasters, 224 Halifaxes and 3 Mosquitos.
• The German controller again follows the progress of the bomber stream across the North Sea and many night fighters are in the stream before it crosses the German coast. The controller is slow to identify Magdeburg as the target, but this does not matter because most of the night fighters are able to stay in the bomber stream, a good example of the way the Tame Boar tactics are developing. The raid is not classified as a success. Some of the Main Force aircraft now have H₂S and winds which are stronger than forecast bring some of these into the target area before the Pathfinders' Zero Hour. The crews of 27 Main Force aircraft are anxious to bomb and do so before Zero Hour. The Pathfinders blame the fires started by this early bombing, together with some very effective German decoy markers, for their failure to concentrate the marking.
• 57 aircraft including 35 Halifaxes and 22 Lancasters are lost. It is probable that three quarters of the losses are caused by German night fighters. During this raid, 2 German night fighter 'aces' are killed: Heinrich Prinz zu Sayn Wittgenstein with 83 victories and Manfred Meurer with 65 victories.
• 22 Lancasters and 12 Mosquitos of Nos. 5 and 8 Groups carry out a diversionary raid to Berlin.
• 1 Lancaster is lost.
• 111 aircraft including 89 Stirlings, 12 Lancasters and 10 Mosquitos, are sent to hit 6 flying bomb sites in France.
• There are no losses.

• 8 Mosquitos are sent to Oberhausen, 5 to Rheinhausen, there are 6 RCM sorties, 5 Serrate patrols, 8 Wellingtons lay mines of St Nazaire and there are 16 OTU sorties.
• There are no losses.

• After being grounded for a full week by bad weather over the Continent, 795 8th Air Force B-17s and B-24s are dispatched against 36 B-weapons sites in the Cherbourg and Pas-de-Calais areas. Results are decidedly mixed due to heavy cloud cover. 401 of the heavy bombers never drop their bombs, but 26 V-weapons sits and several targets of opportunity, including three airdromes, are eventually attack by 394 bombers releasing 1,141 tons of bombs.
• 6 bombers are lost
• Escort and support for the mission is provided by 628 USAAF fighters. USAAF fighters down 7 Luftwaffe fighters.
• 1 P-47 and its pilot are lost

• XII Bomber Command B-25s attack a bridge at Pontecorvo and rail lines around Rome.
• XII Air Support Command A-20s attack Atina.

• 325th Fighter Group P-47s down 4 FW-190s near Florence about 1230 hours.

• In an effort to stop at the source Luftwaffe bomber attacks on shipping and bases in Corsica and Sardinia, a total of 72 15th Air Force B-17s attack the Luftwaffe airdromes at Salon-de-Provence and Istres-le-Tube about noon with an aggregate of 228 tons of bombs. Damage is heavy and both bases are put out of commission temporarily just as a major Allied amphibious landing is about to take place in central Italy. 6 Luftwaffe fighters are downed over southern France by 1st and 82nd Fighter Group P-38 escorts.

• 15th Air Force B-24s attack marshalling yards at Pisa, Pontedera, and Prato.

Allied Planning

CBI

Gen Stilwell decides to attack towards Walawbum with an armored spearhead, followed by infantry. The 113th Regiment of the Chinese 38th Division digs in at Ningru Ga, a little more that three-quarters of a mile from Taihpa Ga.

Eastern Front

The Soviet attacks near Leningrad continue. Troops of the Soviet 8th Army of the Volkhov Front occupy Mga, 25 miles southeast of Leningrad, and the advance goes on toward Tosno. In the Ukraine, troops of Vatutin's 1st Ukraine Front and Konev's 2nd Ukraine Front have the 1st Pzr Army trapped in a pocket in the area of Korsun-Shevchenkosky, west of Cherkassy and south of Kiev. The Germans are supplied by an improvised air lift as they try to fight their way out.

Mga falls to the 8th Army. Tosno, another major site for the German siege arty, is threatened but the 18th Army is powerless to halt the Soviet advance. Kuchler has his hands tied by Hitler's rigid insistence on a static defense.

Italy

In the British X Corps area, the German, having brought up reinforcements, begin a series of strong counterattacks against the Garigliano bridgehead, which extends from the river to Hill 413 and from there to Salvatito Hill.

The attacks of US II Corps continue but only very small holdings across the Rapido can be gained and these are quickly attacked and eliminated by the Germans. South of Sant' Angelo in Theodice the 143rd Regiment succeeds in crossing the river but is forced back on to the south bank almost at once. North of Sant' Angelo some units of the 141st Infantry Regiment have managed to establish a bridgehead, but it remains isolated.

In the afternoon a new attack by the 143rd Regiment allows 5 companies to stabilize another bridgehead, but during the night it is wiped out by the Germans. The US 36th Division loses very heavily in the day's action.

The forces for the Anzio landing bgin an uneventful voyage from the Naples area to Anzio. To deceive the enemy, naval forces bombard Civitavecchio and feint landings there.
