On 26 August 1863, the regiment received two orders from Army headquarters about sutlers. One was about sutlers' "supplying the wants of officers". The other was about "regularly appointed sutlers and no others to be appointed". On 31 August 1863, the regiment received an order from brigade hq about sutlers, dated 24 August 1863.
On 27 April 1864, Sinex reported that neither F. Klim, the former sutler of the 91st, nor the present sutler, Robertson, had ever been assessed (letter, Sinex to Fowler, 27 April 1864).
On 13 September 1864, Sellers notified company commanders of the regular monthly inspection, and called their attention to various regulations, and to article 29 of the articles of war, which forbade sutlers from selling liquor at various times.
On 20 November 1864, William B Robinson was the 91st's sutler (by order of the War Department) [letter, Sellers to Bartlett, 20 Nov 64].
On 29 November 1864, Sellers reported that the sutler had paid no tax [letter, Sellers to Bartlett, 29 Nov 64].
See article 25 of the Army Regulations.
Robert Eyre, brother of Benjamin and George Eyre, worked for an Army sutler, perhaps as a clerk.
