I have in my notes the RAF raided Aulnoye, Friederichshafen, and Montzen with a force of 665 Dispatched and the loss of 35.
I have those losses "claimed" as 15 Lancs and 31 Halifax between 0119 and 0310hrs on the night of 27-28 April 1944 by the nachtjagdwaffe. Are you talking about actual Lanc. losses, or claims by the NJG? My original post was only refering to claims made against Lancasters...
I could very well be wrong though
