I was one of the first five Americans to arrive in Canada in what became Detachment 1, HQ, ADC. Initially we four were Det 1, HQ, 32d Air Division & were ourselves supported from Minneapolis - St. Paul, MN. Four of us were a disbursing office and the fifth was an officer in charge of the BX stores (now AAFES, "We go where you go.") at each site. I'll omit the names of the others for now.
Initially, we four finance people were in Winnipeg. We moved to Ottawa in Dec. The Exchange office remained in Manitoba.
These AC&W sites eventually each published a newsletter from time to time AND sent COPIES to the families of personnel on site.
The newsletters would be helpful to anyone interested in the story of the U.S.Pinetree Line personnel.
