Another memorable event was the second 1,000 bomber raid on Bremen with 960 aircraft from Bomber Command, 102 from Coastal and and five from Army Co-op, a total of 1067 aircraft. Herbís was given ten minutes over the target, to clear the area quickly because of the risk of being bombed from aircraft at a higher altitude. Herb was in the rear turret for this raid and says that he sat on his tin hat just in case. They found a hole in the heavy cloud, made one run, dropped their bombs and got out fast. His squadron sent out 12 aircraft without loss but Bomber Command lost 49, including 22 of their OTU crews.
In 1942 Herbís squadron converted to B-24 Liberators for long-range anti-sub and convoy escort duties. They now had a crew of seven - pilot, co-pilot, navigator and four WOP/AGs. Their longest flight was 14 hours and 45 minutes meeting the Queen Mary with 20,000 troops on board. They converted again to B-17 Flying Fortresses. On one trip they met a F.W. Condor (FW200). After an exchange of gunfire, the FW 200 escaped into cloud with one engine smoking. One of the shells feom the FW 200 passed through the seat where the operator had been sitting minutes before. Most flights, Herb remembers, were monotonous without ever seeing a sub. After 43 operational flights, Herb ended in Aldergrove, Northern Ireland, where his crew was taken off ops.His next posting represented hard duty ! To Nassau in the Bahamas, to train Czechoslovkian crews with flights to US bases in Cuba & Jamaica, with time spent on sunny beaches and in colonial-style clubs. For all this, they were paid an extra 7s 6p a day.
