Graeme:
My dad was also in the 83rd Battery, of the 23rd Field Regiment of the 4th Canadian Armoured Division which was part of the 2nd Canadian Corp., of the 1st Canadian Army. You can check out an article on the 23rd Field Regiment on www.wikipedia.org and
in the search box type in the exact words "23rd Field Regiment, RCA". If the article doesn't show right away, then look at the
list of possible articles that are displayed and click on the one with this same wording, with a high % probabilty.
In this article it explains how the 83rd battery was one of the batteries in the 23rd Regiment and what activities they were involved in
in WW11. It will give you some understanding of where your grandfather was and when., but sorry it doesn't include anything on
the color of berets they wore.
