John J. Dye applied for a Confederate pension from Phillips County, Arkansas, in 1902, citing his service in Co. K, 1st (Dobbin's) Arkansas Cavalry, in 1865.
Capt. William Weatherly's Co. K was recruited primarily in Phillips County. Like all the companies in Col. Arch Dobbin's 1st Arkansas Cavalry, the records are largely imcomplete -- mostly consisting of the parole records of those men who were present at the final surrender at Wittsburg, Arkansas, on May 25, 1865.
However, Private Dye's pension application was approved, so he apparently was able to provide some sort of documentation (probably affidavits from former comrades) to prove his claimed service. Lots and lots of men of Dobbin's regiment were in this same situation -- they served, but do not appear in the highly fragmentary wartime records.
