text: It had been planned that the fourth and eight rows of Lancasters would not bomb on the first pass and Flight Lieutenant L. S. Goodman reported that on the second bomb run the bridge was under water, the spans having been broken or blown off their piers. A third Lancaster crew found that their bomb would not drop, despite two attempts and the bridge collapsed before the third try, leaving the crew to take it home. A fourth Grand Slam was reported to have hit the east end of the structure. Reconnaissance photographs showed that the bridge had been destroyed.
  Bremen, 23 March
  Another railway Bridge near Bremen was attacked later in the day by twenty 617 Squadron Lancasters, six carrying Grand Slams and 14 with Tallboys. The bridge at Bad Oeynhausen was attacked by 9 Squadron. The weather was clear and ideal for bombing but was also good for the Bremen anti-aircraft defences. The bombers were escorted by 41 Mustang Mk IIIs from 11 Group with seven more squadrons in the vicinity. A total of 128 Lancasters took part in the bombing from 1 Group and 5 Group, most accompanying 617 Squadron on the attack on the bridge at Bremen. The Germans started to generate a smoke screen but were too late; two hits were observed before the smoke screen and wreckage blocked the view. The pitch control on one of Lancaster PB996's engines made the aircraft lose speed and its bomb was dropped on a jettison area; the pilot of PD112 decided to bomb despite the bomb-aimers clear vision panel being smashed by flak .
