Hallo Peter,
Welcome back ! It is good to have the fates of L5446 and L5516 clarified. However that now leaves L5465 out in the cold. If Sidney Shail is correct - and I do not doubt it - L5465 was assigned to the AASF only on 20-5-1940 and to 103 Squadron on 23-5-1940. So it could not have been lost on the May 14th mission. Most likely, I suppose, it was one of the 14 unidentified Battles lost by 103 Squadron from May 25th to June 15th inclusive ?
K9366 damaged on May 10th. Errr......! It must have been one good holiday Peter ! I found that information on page 182 of a little-known book called
The Battle of France, Then and Now by someone whose name escapes me at present !
Regards,
Martin.
