Splendid digging, Colonel. Strange how these obscure gems turn up even though they are not mentioned in the usual places.
However, one thing does bother me. Why would they have sent three Mosquitos all the way from RAF Station Manston/U.K. via S France and NE Italy to bomb a couple of obscure and relatively unimportant airfields around Zagreb? We certainly had enough air assets in the Mediterranean by October 1944 to handle this operation, and the 4 Zagreb area airfields Gorica, Lucko, Pleso and Stadt) were under 'round-the-clock surveillance and frequent air attack. (see:
http://ww2.dk/Airfields%20-%20Yugoslavia.pdf - under Agram (Zagreb).
Was there any mention in your 605 Squadron history of there suddenly being a vital or very important target there that needed to be eliminated, and that only Mosquitos brought down from England could perform this mission because of the need for utmost secrecy and/or special on-board equipment that no aircraft in the Mediterranean Theater had?
Most perplexing.
