This is getting long in the tooth, no new information has been added here, I was hoping for more.
The list of returned battle flags, 1905, list WD#171 as that of the 32nd Va. Battalion captured by Private Edward Hanford Co.H 2nd US Cavalry near Woodstock Va.
The MoC listed WD#171 in the late 1960’s as belonging the 35th Va. Cav. Battalion captured at Toms Branch. (Toms Branch is a little north of Woodstock, Va.)
1976-77 Howard’s research of the flags at the MoC list WD#171 as being captured in the area of bridge across Town Run Creek, where Millwood Pike and Front Royal Pike crosses by Gen. James Wilson 1st Brigade, 4th Division, Cavalry Corps, Army of the Shenandoah, Oct. 1864. On white canvas header is marked - Virginia 1st Mounted Rifle Battalion. Side note: He listed WD#155 as that of the 35th Va. Cav. Battalion.
Research done by Rebecca Rose and team at the MoC verify that WD#171 was captured in the area of Woodstock, Va.
The ID on WD#171 by Howard & the MoC is 34th or 36th Va. Cav. Battalion.
A 1990’s research by outside people claim that WD#171 was captured at Toms Creek, which is mush farther south but the supporting evidence presented had already been debate in the 1960’s.
Without more supporting documentation WD#171 is the battle flag of the 34th or 36th. Now the 34th may have had or received a second ANV but I have no information to support that. Prior to receiving their ANV pattern battle flag, it is probable that they carried a VA. State flag or a homemade 1st National as some of their sister battalions did.
