Fighter Command claimed six enemy aircraft destroyed, three damaged, and one probably destroyed. It suffered a rare loss when a Mosquito Mk XIII piloted by Wing commander Mack, commanding 29 Squadron, and Flight Lieutenant Townsin failed to return after a patrol and were posted missing. Peltz ordered another attack for the 23/24 February, after the perceived concentrated (and successful) attack the previous night. I./"KG" 6 sent to 10 crews of the 130 (German sources say 161) and were to begin their attack at 22:00. I./"KG" 66 were ordered to mark the target area with white flares which were set to burst at 10,000 ft above the cloud layer. All the formations except III./"KG" 6, which was flying from Belgium, were routed via Evreux and Le Havre, north to High Wycombe where four red flares would mark a turn to the south east across London. This time the target codename "Hamburg", which placed the centre of the attack in the vicinity of the Isle of Dogs. The target area suggests that the intention was to inflict economic losses by striking at London's docks. Yellow flares marked the bombing run at 11,000 ft, and the run-in would be conducting at an altitude of 13,000 ft; reduced down to 3,500 ft once the city was cleared. German formations from "KG" 2 and 6 carried a mixed ordnance SC500s, AB500s, AB1000s and BC50s for the attack. Colchester was hit badly by 1,400 incendiaries which started a large fire in the town centre. 15 properties were destroyed and 99 damaged. 75 fire-engines and two million gallons were needed to extinguish the flames. There was only one casualty in the town and no fatalities. A total of 185 sorties were flown. Five bombers were lost; one to ground fire and another to a 605 Squadron Mosquito. Amongst the losses this night was Do 217M-1, code U5+DK, "Werknummer" 56051. At 10,000 ft over London the aircraft was hit by predictive fire from the ground. Pilot "Oberfeldwebel" Hermann Stemann ordered the crew to abandon the aircraft over Wembley and they were promptly captured. The bomber flew on for 60 miles making a near-perfect forced landing north of Cambridge. The intact bomber enabled British intelligence to examine both it, the FuG 214 tail-warning radar and the ordnance on board.
