Re: Stable Sgt. Lewis SMITH - Troop A 10th Cav.
I'm probably late in this reply--but I just ran across your message while scrolling postings on this site.
The rank of Stable Sergent probably was authorized post l889. I checked original copies of the army regulatons for l88l and 89 in my library--and no mention of this rank.
But I have run into term in my research from this period and I suspect the "rank" was temporary and not permanent: it came with duties/responsibilities/authority--but no increase in pay. Very much, I suspect, like the posting of a Sergeant or Corporal of the Guard(which changed daily).
However rank of Stable Sgt may have been added to troop/regimental tables of organization post l889.
As of l889 regulations, the rank and "precedence" of various grades of sergeant were:
Sergeant Major (regimental)
Quartermaster Sergeant (regimental)
Post Ordnance, Commissary and Qusartermaster Sergeants, and Saddler Sergeant (regimental)
First Sergeant (company, troop and battery)
Sergeant (company, troop and battery)
l889 monthly rates of pay during first year of enlistment ranged from a high of $34 for post Ordnance, Commissary and Quartermaster Sgts, to $23 for Sgt Majors, to $22 for comapny lst Sgts, to $l7 for
company/troop/battery Sgts. Pvts earned $l3 a month.
Interesting, regimental Sgt Majors "ranked" post Ordnance, Commissary and QM Sgts, but earned $11 a month less pay.
