Uncle Bob,
Just a question on the 7th Cav... Having been a member of (once as an AD division, and now an ARNG division)I don't recall our histroy as part of the Cav. when I was up in front of the E-5 board.
Our Unit was originally IIRC, part of the 18th Division of the US Civil War, deactivated. Reactivated as 7th INF 1904, was part of the Moro Insurrection AEF under Pershing 1911; was part of the 1919-1921 SIberian campaign (we have the distinction of the only US outfit to shoot Red Russians on Mother Russia's soil); In WW2 we fought in two theatres of the war (the bulk of the division was in the Pacific, 1 Presidential Unit Citation; a portion of it was in Western Europe (Arty/HHC).
Our next campaign was in Korea, three Presidential Unit citations; deactivated 1963-64 then reactivated 1965-66, into Vietnam, 1 Presidential Unit Citation; then in Panama (Just Cause/Promote Liberty). We were deactivated June 93. We were reactivated June 99, as an ARNg division (made of three Brigades from three States: Oregon's 41st INf/ Oklahoma's 45th Inf/ & the 39th Inf here in Arkansas.) with an AD Hq element at Ft Carson, CO.
If we had any Post Civil war history as part of 7th ID it wasn't made well known to us, so the Wounded Knee reference is lost to my memory.
IIRC the unit in "We were soldiers once" was the 173rd ABN Inf Regt. based out of Ft Campbell (whose most famous Regt commander was Col Hackworth, after the fellow who took them into Nam), whose billets were ours in the 187th, "Rakkasans".
7th ID was in theatre in Nam, but the unit in the book was from Ft Campbell's 101st ABN Air Mobile Inf (later changed to AASLT div,). Where I also served (93-99). Ft Ord was the home of the 7th ID from 1941-1993. (my tour on the Planet Ord was 90-93).
I'm not nit pickin, just unit history UB-which was at my E-5 & E-6 boards.
