Hi Jim,
I'm also researching an uncle killed with the Reginas and can try to provide a little of the knowledge I've managed to pick up over a number of years.
War Diaries - I have copies of the Regina War Diary for the months they were in combat. This is only the narrative part, and doesn't include the more detailed appendices that include message logs, patrol reports and the like. I don't have it at hand, but it's a PDF of 4 or 5 MB that I could email if you haven't already obtained them from the Archives. If you are a little more patient, I hope to have a Regina Rifle web site up in the next couple of months that will include the diaries, casualty lists and other info. It's intended to provide info for researchers just like us, and that can be difficult to access if you aren't in Ottawa. I'll post a link here once it's up and running. Email me at
klambie15 (at) hotmail.com if you'd like the PDF and a file that big won't choke your internet connection.
July 8 1944 - Another source of info on the Reginas attack that day was published in Canadian Military History in the Spring 1995 issue. You should be able to get a back issue here:

This is written by Gordon Brown and has much overlap with 'Look to Your Front' which he co-authoured, but may be of interest. It's only a very tiny clue, but B and C Companies took the heaviest casualties that day (D Coy less so), so there is a better chance he was in one of those Coys.
Time with the Reginas - Based on what you have posted from his records, he was a reinforcement for the Reginas in mid-June 1944. He landed in France on 12 June, and according to other documents I have (Part II, Battalion Orders), was taken on strength 15 June with 24 other North Shore Regiment reinforcements. Most of these were also New Brunswick boys based on their service numbers. Based on the similar story for my uncle (6 June reinforcement, killed 4 July), you will have a difficult time placing him in a Company. The Regina diary does not include Company assignments for reinforcement drafts, as some diaries do. Assignments only appear in Part I of the Battalion Orders. They exist for the period prior to the invasion and resume again with some consistency in Aug and Sept of 1944. In between, they are extremely sparse. I have so far been unable to place my uncle in a Company. Further research in non-official sources and contact with veterans are the best remaining avenues to track this sort of info.
Will try to chip in with additional info, though interpreting personnel records is not a strength.
