Can anyone help identify this missing officers regiment? He's listed on CWGC as being with 53 Medium Regiment but this does not appear to be the case as he's not on that regiments Field Return for their duration in France. Also any details on his death would be great. The 53rd Medium Regiment website states he was drowned on a ship but do not quote the source. They have been contacted but no reply to date. 126300 Lieutenant Thomas Nicholas Halford, died 29th May 1940. Remembered on the Dunkirk Memorial.
