Air Operations, Europe

• The Battle of Hamburg continues with 777 aircraft making a raid on the city. Included in this total are 340 Lancasters, 244 Halifaxes, 119 Stirlings, 70 Wellingtons and 4 Mosquitos.
• The marking for this raid is again all by H₂S. The plan is to approach Hamburg from almost due north and hit the northern and northeastern districts which had thus far not been hit. The Pathfinders come in more than 2 miles 2 far to the east and mark an area just south of the devastated firestorm area. The Main Force bombing 'creeps back' about 4 miles through the devastated area, but then produces a very heavy bombing in the Wandsbek and Barmbek districts and parts of the Uhlenhorst and Winterhude districts. These are all residential areas. There is a widespread fire area, but no firestorm, which the exhausted Hamburg fire units can do little to check.
• 11 Halifaxes, 11 Lancasters, 4 Stirlings and 2 Wellingtons are lost.

A Lancaster crew of No 61 Squadron, Systerston, prepare for the night's mission.

Britain, Home Front

The minister of labor, Ernie Bevin, announces that women up to 50 must now register for war work. This is a sign of the strain on manpower resources produced by Britain's more complete mobilization for war production. As the war continues this will become more pronounced and will be an important factor in Britain's negotiations with the Allies.

Eastern Front

In order to improve it positions on the Mius River von Kleist orders several counterattacks. The III Pzr Corps attacks the Soviet positions on the Mius River north of Taganrog but with little effect.

Germany, Home Front

Goebbels is active visiting bomb-damaged areas of Germany and sees for himself the horrifying extent of the destruction meted out by Allied air attacks. He writes in his diary this day following one of the heaviest single raids on Hamburg: '1,000 bombers, Gauleiter Kaumann spoke of a catastrophe the extent of which blunts the imagination. A city of one million people has been devastated in a manner unknown before in history; problems almost impossible to solve; food for a million people shelter, clothing, 800,000 homeless people wandering the devastated streets.'

New Georgia
