wrxflame - Thanks for another great WW2 pic. HMS Patroller was an escort carrier, and used as an aircraft ferry as well. The aircraft on the deck were possibly being dumped at sea at the end of WW2 - but it appears more likely that these are new aircraft being ferried, due to the lack of damage to airframes, and an appearance that protective coverings are in place over the aircraft.
Below is an interesting "write-up" of a sister escort carrier to HMS Patroller, HMS Reaper.
It appears that some of these early escort carriers were hastily modified merchant freighters - whereas later escort carriers were more extensively redesigned as carriers, despite all of them being based on freighter hulls, anyway.
There were a total of 19 of these escort carriers built.
