Hi Michael,
Here's what I have:
10th October, 1943. I cannot find reference to a claim by Thyben, but I have found only one P-47 loss:
P-47D-5-RE 42-8635/PE- of 328th FS, 352nd FG. Lt. Fred Olson (KIA after baling out off Lowestoft due to battle damage)
Attributable to Knoke or Fuehrmann?
30th November, 1943.
42-8514/PZ-P of 486th FS, 352nd FG. Lt. David Kramer, seen to bale out but KIA as well
Film C. 2031/II Anerk: Nr.371;

11th February 1944
I (very tentatively) hazard a guess that his claims were tied in with the 20th FG losses suffered at the hands of JG 26
Includes 77th FS: 42-67726/LC- of Lt. Miles N Keathley POW, 42-67728/LC- of Lt. Joseph O Minton KIA, 42-68036/LC-M of Col. Robert P Montgomery whilst 79th FS lost: 42-67718/MC-C Lt. Donald W Cooper KIA, P-38J-10-LO 42-67821/MC- of Lt. Leonard S Smutko POW (lost over Irsch), 42-67848/MC- of Lt. Melvin H Orr POW and also 42-67850/MC-S of Lt. Myron R Sands also POW, 42-67760/MC- of Lt. Neal J Archer Jr KIA and 42-67981/MC-G "Puddin'" of Lt. Thomas A Hanzo POW
...Bearing in mind that there is a good half hour between Thyben's claims and JG 26's... But in any case these are the only P-38 losses I could find for that date, either 8th AAF or 9th AAF
Hope I have helped somewhat...
In friendship, Nick
