I'd forgotten many of the nurses at BMH Iserlohn, at least for a couple of tours there, were French-Canadian/Francophone. And, yes, many of them while fluently bi-lingual, often refused to converse in English or would do so only under duress. It's a real political issue in Canada (well, down in Eastern Canada, not so much out west where I now reside).
We also had a couple of French-Canadian regiments (Vandoos or Royal 22nd) and many of the younger soldiers could not speak English, or did so very poorly. Since Canada is officially a bi-lingual country, they could literally spend their entire career never having to speak English! If any superior officer happened to be Anglophone, and some were, the onus was on them to learn and speak
En Francais!
Many babies got born in the back of a bumpy ambulance...some of which must have dated from WWII LOL (heck, maybe even WWI...nah...). Nothing like having mom tossed around over cobblestones to induce labour.
