401st Bomb Group, Mission No 1, 26 Nov 1943, Bremen, Germany. 0908 hours - Twenty aircraft off okay. Four of the briefed crews didn't manage to get off the ground. A 614th ship dropped off the perimeter track, and in doing so trapped the 615th Squadron Commander, Major Seawell, behind it. Then, as Lt. V.J. Kaminski neared the tail of Lt. Ralph Dempsey's ship and attempted to brake, he had a brake failure. In the ensuing collision the tail of 42-31091 was demolished by the props of 42-39873. The primary target was obscured due to a 10/10's undercast, so bombing was done at 25,000 feet using PFF methods. Aircraft 42-37833 "Fancy Nancy" as struck from below by a B-17 from another group, cutting off the ball turret and killing the ball turret gunner, Sgt. L. Baranik. The ship was able to return, but force-landed at RAF Detling in Kent, where it was declared damaged beyond repair and scrapped.Eight other aircraft from the 401st suffered minor flak damage.

401st Bomb Group, Mission No 2, 1 Dec 1943, Solingen, Germany. The Group flew the low position in the 1st Combat Wing, and this was the third wing over the target. They encountered 25 to 35 FW-190's over the target itself, but the escorting fighters did a good job of protecting the bombers, and although the attack went on for about 30 minutes the Group suffered no losses. The target was bombed using PFF methods. On this mission the Group received credit for bringing down its first enemy aircraft. It went to Sgt Percy W. Stengel, a ball turret gunner with the 612th crew of W. J. Kelly.

401st Bomb Group, Mission No. 3, 5 Dec 1943, Paris, France. Aircraft 42-39825 crashed on take-off into the village of Deenethorpe. It was believed a combination of prop wash and icing resulted in loss of power and caused the port wing to sink until it touched the runway, turning the aircraft to port and down the hill into the village. Eight of the crew managed to scramble clear and dashed around the village to warn the inhabitants to run for their lives before the burning plane exploded. The navigator and bombardier were in the nose of the aircraft and were badly injured. They were bravely rescued by ground personnel and recovered eventually from their injuries. Twenty minutes after the crash, the aircraft, load with 6000 pounds of bombs and over 2000 gallons of aviation fuel, exploded with a tremendous roar, taking the 401st fire tender up with it. The ground crew who braved the burning aircraft to rescue the injured men were M/Sgt Earl K. Williams and M/Sgt Francis F. Snider, who dragged clear Lt Carl T. Floto (the navigator), and Capt Ralph J. White and Cpl William N. Luna who rescued Lt John J. King (the bombardier). The loss of the fire tender should have meant that the Group be diverted to other bases upon returning from the mission, but this also had its problems. The aircraft were still loaded with bombs and the crews on their first or second missions in most cases. After much heartsearching permission was finally given for them to land back at the base without a fire truck standing by. The touch downs were without incident and everyone breathed again.

401st Bomb Group, Mission No. 4, 11 Dec 1943, Emden, Germany. 1521 hours - All aircraft down except 42-31098 (IW-B - "Penny's Thunderhead") which landed at Lindholme RAF base, Yorkshire, after sustaining heavy battle damage (eight crew members having bailed out). The 1st, 2nd and 3rd Air Divisions sent up 523 four-engine bombers on this mission with 17 aircraft lost and 138 aircraft damaged. The claims for the bombers were 86-22-23 and the fighters 21-0-7.

401st Bomb Group, Mission No. 9, 30 Dec 1943, Ludwigshaven, Germany. This was the longest mission yet flown by the Group with ten hours engine time recorded. The target was attacked by PFF method in Wing formation. No results were observed. The 401st suffered its first combat-related aircraft loss on this mission, when ship 42-39826, piloted by Lt. Trian Neag, was shot down by flak near Saarbruken, Germany.

401st Bomb Group, Mission No. 10, 31 Dec 1943, Cognac, France. The primary target (Bordeaux) was obscured by cloud so the Wing Leader (Major Seawell) ordered the formation to proceed to the secondary target, a Luftwaffe Airbase at Cognac, which was bombed with excellent results. Major I Wayne Eveland, 614th Squadron Commander, flying with Lt. H.E. McDanal and his crew in "Flak Rat" (42-37770) was shot down by fighters but evaded capture, ultimately returning to Deenethrope via Spain. The wreckage of B-17 aircraft "Hey Lou" (42-31064), piloted by Lt. D. H. Lawry, was found off the coast of southern England. The cause of the loss was not determined, and only one body was recovered. Two other aircraft ran out of fuel and were abandoned by the crews.

401st Bomb Group, Mission No. 14, 11 Jan 1944, Oschersleben, Germany. This was one of the greatest air battles of World War II. The Group put up the most aircraft to date as part of a maximum effort. German resistance was fierce, involving heavy flak, dozens of fighters and balloon mines. The Group shot down a number of Luftwaffe fighters. It was on this mission that Major James Howard, a P-51 pilot, remained after all other U.S. fighters had left and engaged a swarm of Luftwaffe fighters attacking the 401st, for which he was awarded the Congressional Medal of Honor. Aircraft piloted by Lt. S.G. Nason ("Pee-Tey-Kuh" #42-31033), Lt. H. J. Chapman ("Carolina Queen #42-37809), Capt. J. H. Foster (#42-39969) and Lt. D.C. Sprecher (#42-39893)were shot down by either fighters or flak. Due to bad weather on return, all aircraft were diverted to a number of other bases

401st Bomb Group, Mission No. 16, 21 Jan 1944, Pas De Calais. 23 operational aircraft were off by 1230. All planes returned safely by 1554 hours. This short mission was to the French rocket coast. It was a successful mission, with no enemy opposition.

401st Bomb Group, Mission No. 17, 29 Jan 1944, Frankfurt, Germany. 35 aircraft were airborne by 0849 but five aborted the mission and returned. Air Raid warning sounded. The Group encountered heavy flak and fighters, resulting in the loss of four aircraft and crews, while three aircraft landed at Deenethorpe with wounded aboard. The crews lost were those of Lt. J. Tannahill (#42-31486),Lt. D. T. Nicklawsky (#42-40057), Capt. R. W. Beers ("Little Boots" #42-31193) and Lt. L. G. Van Syckle (#42-38012).
