Operational Narrative – High Combat Box:
  1. General Narrative. Twenty aircraft of the 351st Group took off at 1630 – 1641 hours. A normal group assembly was made at the Deenethorpe buncher, with the 351st briefed to fly as high group and to form at 11,000 feet. The Lead Group appeared to be higher than its briefed altitude, and made necessary the decision to form the High Group at 11,500 feet, which was accomplished. Departure from Deenethorpe to Point A was made one minute early.
     Formation of the combat wing was made as briefed, although the groups did not take up a close wing formation. The low group remained behind, and the high group experienced some difficulty in keeping in position due to over-running, although the airspeed reading was 140 – 145 MPH.
     The Division assembly was made as briefed, and the formation departed the English coast one minute early. The combat wing formation was still loose, and the high group was forced to “S” to remain in position. The preceding combat wings were noted to be in position, with the proper interval. Visual reference was maintained at all times.
     The enemy coast was reached as briefed, and visibility was unobstructed in all directions. Some difficulty with the combat wing formation was experienced through the reasons previously given. No difficulty was experienced with navigation, though the Lead Group Navigator was slightly off course at times.
     At the IP, the low box was so far behind that the high group was forced to fall in behind the lead group and bomb second, the only alternative being to make a 360° turn, which was deemed inadvisable due to the proximity on both sides of heavy flak batteries. The low group Leader was called on VHF and advised. The rally after bombing was normal, and the route back to the enemy coast was flown with no difficulty, the combat wing being in excellent formation.
     Flak was encountered over Holland, and shortly after the turn away from the target. Flak was light and inaccurate. No enemy fighters were seen. The fighter cover was as briefed and excellent at all times.
     The combat wing formation was broken up at mid-channel. The high group pulled to the right and the squadrons were told to fly level and 300 feet from the formation. The let-down took the high group directly over the home field and landings were made without incident.
     The mission presented no difficulties except the maintenance of combat wing formation until rally, after which there were no difficulties.

  2. Aircraft Not Attacking. Twenty aircraft took off and formed as indicated on the Formation At Take-Off Diagram. Seventeen were dispatched, two of which returned before the target was reached.
     Aircraft 42-39760, pilot Lt. Keese, returned from the English Coast when the #3 induction system (Elbow assembly) was blown. Aircraft 42-31757, pilot Lt. Overholt, returned from a point twenty miles north of Deenethorpe because of internal failure of #2 engine. Aircraft 42-30994, pilot Lt. Johnson, returned from 52°40’N-00°30’W [just north of Stamford, England] because of a blown spark plug, #4 cylinder of #2 engine. These aircraft were not dispatched.
     Aircraft 42-31711, pilot Lt. Blaisdell, returned from 52°38’N-05°05’E [over Hoorn, Netherlands] when it was found impossible to maintain position in the formation. This aircraft was dispatched.
     Aircraft 42-31702, pilot Lt. Roper, was scheduled as a flying spare. After a late take-off, it was found impossible to get into formation. Turned back at 52°37’N-04°37’E [just north of Egmond aan Zee, Netherlands]. This aircraft was dispatched.
     The remaining fifteen aircraft continued on course to attack the target in the formation indicated in the Formation Over Target Diagram.
  3. Aircraft Lost. No aircraft were lost on the Mission of 22 April, 1944.

  4. Group Leader. Major Franklin A. Richardson, flying in aircraft 42-38005, led the High Combat Box.

Preliminary Damage Assessment:
  1. The target was the marshalling yard and shops at Hamm, Germany. Intense smoke covered the assigned aiming point. A secondary aiming point in the lower marshalling yard was selected. The smoke was a result of previous bombing and smoke screen generators.
  2. The bombs of this group fell across the lower marshalling yard approximately 1,970 feet from the southern choke point. The pattern was drawn out measuring 3,942 feet by 1,576 feet and the greatest concentration fell in open fields beyond the marshalling yard.
  3. Approximately 40% of the bombs fell across the yard and damage should be heavy. The bomb pattern ran across eight trains parked in the yard and they will receive probable damage.
[Signed:] Thomas L. Cooper, 1st Lt., Air Corps, Group P.I.[Photo Intelligence] Officer


Intelligence S-2 Reports:
  1. No leaflets were carried on today’s mission.
  2. Bomb bursts of previous wings caused a heavy smoke over the briefed MPI [Mean Point of Impact]. Another MPI was selected further south in the Marshalling Yard, and a preliminary study of photographs shows a fairly compact pattern in the southern end of the lower Marshalling Yard. The pattern extends across the Marshalling Yard and into a small village. Bombing results should be good.
  3. No enemy aircraft were encountered during today’s mission.
  4. Moderate flak was seen at the target on the approach, but when this formation arrived only a few inaccurate bursts were encountered. An intense barrage was observed over the Ruhr, but this formation was out of range. A very large flak “scare-crow” burst was seen near Hamm, which gave the appearance of a plane burning. Moderate, inaccurate flak was encountered from Ostend on the route out. A huge yellow burst of flak was observed here which showered out flaming particles after the burst.
  5. Crews reported ground objects visual all along the route. There was a slight haze over the target area, but this did not interfere with visual bombing.
  6. No unusual observations were made over enemy territory.
  7. Fighter support was reported as excellent. No B-17’s were observed to be in serious trouble.
[Signed] Robert P. Ramsey, Captain, Air Corps, Group S-2 [Intelligence]

6. Flak encountered or observed en route. (In the order experienced) -
 Intense barrage observed over Ruhr, but this formation out of range.
 Moderate flak encountered from Ostend. This was fair for height but poor for deflection.
