COLOGNE
357 Lancasters and 22 Mosquitoes of 1, 3, 6 and 8 Groups. 4 Lancasters lost.
This concentrated attack fell into areas of Cologne which were north and west of the city centre and partly industrial in nature. 192 industrial premises suffered various degrees of damage, together with 725 buildings described as 'dwelling-houses with commercial premises attached'. 7 railway stations or yards were also severely damaged.
But more general city buildings were also heavily bombed: 46 churches and chapels, the Opera House (partly burnt out), the city market halls, etc. The Capitol cinema, the largest in Cologne, was destroyed by fire. 1,861 houses or apartments were destroyed and more than 20,000 damaged. There were 1,290 separate fires. 664 people were killed and 1,067 were injured. The Cologne report mentions 'high-explosive bombs of new calibre which penetrated the normally safe basement shelters'; 80 percent of the dead were in those shelters.
LA CHAPELLE
The raid on this railway target just north of Paris was the first major test for the new 5 Group marking method, with the group employing not only 617 Squadron's low-level markers but the three Pathfinder squadrons recently transferred from 8 Group. A few regular 8 Group Mosquitoes were also used to drop markers by Oboe to provide a first indication of the target's location for the main 5 Group marking force. 247 Lancasters of 5 Group and 22 Mosquitoes from 5 and 8 Groups dispatched. 6 Lancasters lost.
The bombing force was split into two parts, with an interval between them of 1 hour, and each part of the force aimed at different halves of the railway yards. There were a few difficulties at the opening of the attack, with the markers of the Oboe Mosquitoes being a fraction late and with communications between the various controlling aircraft being faulty, but these difficulties were soon overcome and both parts of the bombing force achieved extremely accurate and concentrated bombing. Unfortunately, no report is available from La Chapelle.

LENS
175 aircraft - 154 Halifaxes, 14 Lancasters, 7 Mosquitoes - of 6 and 8 Groups. 1 Halifax lost. The railway yards were accurately bombed, with particular damage being caused to the engine-sheds and the carriage-repair workshop.
