Air Operations, Europe

• Cologne is the target of 608 aircraft - 267 Lancaters, 169 Halifaxes, 85 Wellingtons, 75 Stirlings and 12 Mosquitos.
• The weather forecast for the target area is not promising, probably covered in cloud. The Pathfinders have to prepare for all possibilities. They do find the target area covered in cloud and use the less reliable skymarking system. 6 of the 7 Oboe Mosquitos that reach the target deploy their markers although late. Despite this, the Main Force delivers its most powerful blow in the Battle of the Ruhr. Berlin describes this raid as 'a terror raid'. This raid completes 6 months of intense bombing activity. Great damage has been done to the German urban landscape, but the armaments industry has not suffered as much as might have been expected. Ammunition and aircraft production remain remarkably high.
• 10 Halifaxes, 8 Lancasters, 5 Stirlings and 2 Wellingtons are lost.

• 4 Mosquitos are sent to Hamburg and 6 Stirlings lay mines in the Gironde River without a loss.

• Of 185 1st and 4th Heavy Bomb Wing B-17s and 6 YB-40s dispatched, 158 B-17s attack port facilities at St.-Nazaire between 1655 and 1713 hours with 300 tons of bombs.
• 8 B-17s are lost, 57 damaged; 3 crewmen killed, 14 wounded, 50 missing
• 43 1st Heavy Bomb Wing B-17s attack the Beaumont-le-Roger Airdrome with 103 tons of bombs at 1736 hours.
• 130 4th, 56th, and 78th Fighter Group P-47s escort the 1st Heavy Bomb Wing B-17s partway to St.-Nazaire, but they are not challenged.

24 98th Heavy Bomb Group B-24s attack the Athens/Eleusis Airdrome, and 22 376th Heavy Bomb Group B-24s the Athens/Kalamaki Airdrome.

Air Operations, Gilberts

In its first combat mission since returning to VII Bomber Command control in March and transitioning from B-17s to B-24s, only 2 of 18 11th Heavy Bomb Group B-24s that were to have been sent from their base at Funafuti Airdrome against Tarawa Atoll actually attack the target. 2 B-24s are withheld due to engine problems, 2 crash on takeoff, 8t are grounded because the runway is blocked by the crashed aircraft, 2 abort, and 2 fail to locate Tarawa.
