I just happen to have had a keen interest in this battle for many years, even though I'm neither Polish, Canadian or German! This is an important site for Poles, in particular, and the brutal centre of their efforts was the Manoir Boisjos (or Bosjos). There was terrible hand to hand fighting here.
I noticed that the map has its labels wrong for the position of Boijos, relative to Coudehard and Mont Ormel.
It should be like this: Top pic from Google earth. Boisjos is inbetween Coudehard and Ormel. Bottom pic from game.
