Feb 1. Thurs (20) 7 hrs. 100 guns Railway bridge at Wessel. (primary) [illegible] 150 guns Circled primary, came back to new IP. and bombed at a secondary which we missed, I think. Mistook marshalling yds. at Dusseldorf for those at Hertford. 6 [illegible] fix showed we missed it. Flak was meager and inaccurate.
