SSA 2 Friends Ambulance Unit in Alsace

[Croix de Guerre]

I am seeking information concerning S.S.A 2 which was attached to the French 66th Division then serving in the Vosges Mountains. According to information I found on a French forum, S.S.A.2 served in Alsace from December 5, 1915 until February 26, 1916.

As far as I am aware, SSA2 was not a Friends’ Ambulance Unit. The only ones I’ve seen referenced in documents I have are SSA13 (in which my great uncle served), SSA14 and SSA19. 
The SSAs were many different volunteer units, not just the FAU so SSA2 may have been BRCS or something else.

Alternatively it may be they have the wrong number. I know SSA19 was further east than the other two, servicing Verdun and other areas.

The Quaker library in London has a lot of info on the FAU as does the Cadbury collection at Birmingham University.Vosges

I haven't been able to find anything about an English/British Ambulance unit No 2 (SSA being Section Sanitaires Anglaise in the context I know) but there was a No 4 serving in Vosges:

This was not an FAU unit - it appears to have been order of St John

 

I also found this correspondence relating to the American Ambulance units and the abbreviation may be used for Section Sanitaires Automobile or Americaine. Unit No 2 is mentioned attached to 66th Division
