Thanks for al those answers.
I have to admit, I posees the excellent book : Le Canadian de la Liberation from Histoire & Collections.
It show complete graphical diagrams on how each regiment or brigade was built up.
However, being a scepticist, I'd like to see actual photographic evidence of Stuarts in Normandy and not just rely on how it should have been.
As NTM points out, they didn't always follow War Establishment.
@ FramFramson : Must be cool to know your grandad was in a that unit.
I only know my grandfather took part in the 18 days of cross country running here in Belgium in 1940 and got transported to an Austrian prisoner camp for some months.
Only 2 weeks ago did my father mention that my great-grandfather is a veteran of the great war which was a first for me.
