Just a point of interest related to this thread, the Start Line for Operation
TOTALIZE was located just slightly east of St. Andre-sur-Orne and ran east through to just slightly east of Hubert-Folie, with the Caen-Potigny Road (running north-south) being the Centre Line (Divisional Boundary Line) between the 2nd Cdn Inf Div (on the west or left) and the 51st (H) Inf Div (on the east or right).
The D89 on today's maps of the area, more or less, follows the course of the start line (west to east).
Also, Louvigny, where the 36x Priest Kangaroos that were allotted to the 2nd Cdn Inf Div, were harboured, prior to the attack, is located, just slightly north-west of St. Andre-sur-Orne.
Cheers
