Alex,
Thanks for PM. It so happens that at same time I now found a reference in the online book "
Silent Skies: Gliders at War 1939-1945" (p. 94-95) by Tim Lynch.
Also see

that set my search in motion.
Rev'd Patterson's death somehow must be placed a month earlier when the first glider flights of Operation Thursday began, on 5 March 1944.
The chaplain was in a US glider with Chalk 19B piloted by Flight Officer Martin J. McTigue (T-060765) with destination Broadway.
It carried some troops of the 1st King's (Liverpool) Reg't.
Glider had to cut loose and landed in thick jungle. Patterson was in the co-pilot's seat and got killed, all others survived.
While on their long escape march the men got ambushed, with 5 men missing afterwards. One eventually returned, only to report that McTigue was executed (his name is now on the Manila Memorial) and three British privates had died in captivity (Sgt. King, Pvt Booth and Pvt Blundell).
It may be so that the date of death of Patterson is with a wrong date on CWGC? On the other hand, it may be that word of his death only reached higher levels a month later.
Regards,
Leendert
