Reading MAW Vol 1 there is nothing listed on 26.9.1941 and there seems not to have been any reconnaissance duties that day.
The loss of F/Lt Brown is listed in that same book on 2.10.1941 due to an Axis report, while, when the authors summarize their own conclusions, they find it more likely it all happened on the third. Reason for that is, I suppose, there was no real activity on the British side on the 2nd while on the third there was in fact a recce mission protected by five Hurricanes with Tomahawks as top cover.
Strangely enough they then continue to place Brown's loss on the second.
Brown received his DFC on 27.9.1941, that is one day after he became a POW if your date is correct. Not sure what was stated in such awards, but if he was already a POW when the medal was given, I feel it should have been noted somewhere.
