DVinsk Regiment before and after 1917?

[Kiwi]

Does anyone know whether the Dvinsk Regiment referred to by Voline, Makno, and Avrich was a newly formed regiment under anarcho-syndicalist General Grachov, or was it the same pre-1917 91st Dvinsk Infantry Regiment (which was based, of course, not in Dvinsk)?  Confusion exists in this, given many of the post-1917 regiment were supposedly imprisoned by Kerensky in Dvinsk.

Thank you for the link, but this article you suggest is the very one that created my confusion, in that it suggests the Dvinsk Regiment formed from soldier prisoners held in Dvinsk at the same time as Makhno (after they refused to return to battle in 1917). 

Voline and other writers of the time do not refer to the Dvinsk by the number of their regiment, but suggest the entire Dvinsk Regiment was imprisoned by Kerensky for not returning to the war.  This suggests that the regiment was "intact" before and after Feb-Oct 1917.  I'll probably assume Voline knew more than the newer source.
