Air Operations, Europe

RAF BOMBER COMMAND
Evening Ops:
  • 165 Halifaxes are sent to attack the Peugeot motor factory in the Montbéliard suburb of the French town of Sochaux near the Swiss border.
  • The outcome of this raid illustrates again the difficulties of hitting relatively small targets in the occupied countries and the danger to surrounding civilians. The night is clear, the target is only lightly defended and the attack altitude is 6,000 to 10,000ft, but the center of the group of markers dropped by the Pathfinder crews of 35 Squadron is 700 yards beyond the factory. The factory is classed as only 5 per cent damaged. Production level is normal immediately after the raid.
    • 5 Halifaxes are lost.
  • 617 Squadron carries out its first operation since the Dams Raid in May. It has been decided to keep the squadron in being and to use it for independent precision raids on small targets. It remains part of No 5 Group and most of its replacement crews come from the squadrons of that group. The targets on this night are two electrical transformer stations in Northern Italy one near Bologna and the other near Genoa. The intention is to disrupt the supply of electricity to the railways carrying German troops and supplies to the battle front in Sicily. 12 Lancasters of 617 Squadron are joined by 12 further No 5 Group Lancasters for these attacks, which are not successful. No flares or markers are carried and the targets are partially hidden by mist. After bombing, the Lancasters fly on to North Africa.
    • 2 Lancasters of the supporting force are lost.
Minor Ops:
  • 6 Mosquitos fly a nuisance raid to Munich, but only 2 actually reach the target.
    • There are no losses.
USAAF
ITALY:
  • NASAF B-17s attack Villa San Giovanni.
  • IX Bomber Command B-24s attack the main airfield and two satellite fields at Foggia.

  • In a major air battle over the central Solomon Islands, AirSols fighters down 45 Japanese aircraft from a formation of 27 G4M 'Betty' bombers and an estimated 40 A6M Zeros. 3 US airplanes are lost. This is virtually the last Japanese Navy attempt to mount an air attack against Allied forces in the central Solomons.
  • VF-21 F4Fs down 4 A6M Zeros over Rendova at 1435 hours.
  • P-40s of the 18th Fighter Group’s 44th Fighter Squadron down a B5N 'Kate' torpedo bomber, a G4M 'Betty' bomber, and 11 A6M Zeros over Vella Lavella and Gizo islands between 1430 and 1500 hours.
  • VMF-122 and VMF-213 F4Us down a total of 15 G4M 'Bettys' and 16 A6M Zeros in running battles between Rendova and Vella Lavella between 1430 and 1530 hours.

    The Canadian 1st Div takes Caltagirone and Grammichele. In the British sector, the battle continues in the area of Lentini and at the Ponte Primasole. In Catania, Col Schmalz, fearing an attack from his eastern flank, withdraws north of the Gomalunga River ant then falls back behind the Simeto River.

    Solomons

    The Japanese carry out a big raid on American troop and shipping concentrations in the central Solomons. 45 of the 75 aircraft taking part are shot down by American fighters. The superiority of US pilots begins to show as only 3 US aircraft are lost. After this defeat the Japanese air force limits itself to night operations.

    Seeing that the situation is not going according to plan, Gen Oscar W. Griswold replaces Gen John H. Hester in charge of the operations in New Georgia. Rear-Adm Richmond K. Turner, commander of the South Pacific amphibious force and of Task Force 31, is also replaced.

    Southwest Pacific

    SWPA GHQ circulates a plan for an attack on New Britain to control the western part of the island from Gasmata to Talasea. The plan outlines an attack by three separate elements to seize Cape Gloucester, neutralize Gasmata, and capture Talasea by a series of amphibious hops along the northern coastline. The Gasmata operation will take place seven days before the main attack on Cape Gloucester.
