I went to the February meeting of the Cambridge branch of the R.Ae.S yesterday evening and in the handout for the lecture there was reference to Flt.Lt John Davenport q.v. It appears he was posted to Coastal Command and after service in the Bahamas (sounds like a tough posting!) he was with 502 Sqdn flying Halifaxes from St David's during the Battle of the Atlantic. During this tour he attacked and damaged U-Boat U802 near Lorient in moonlight. He later received the DFC for his bravery. Hope this helps.
