The following is from the Mosby Heritage Area Association website:
On a cold January 10th (2007) Mosby historians and interested parties assembled at Loudoun Heights for the dedication of a Virginia State Highway Marker noting the actions of John S. Mosby and his Rangers at Loudoun Heights on January 10, 1864. A member of the Historic Mosby Rangers from Washington state, representing the group that spearheaded the fundraising efforts to have the marker erected.
Don Hakenson, Mosby historian, gave a moving talk on the action that took place on that January 10th day in 1864. Mosby and scout Frank Stringfellow had planned a joint attack on Major Henry Cole’s Union forces camped at Loudoun Heights. A gun shot alerted Cole’s cavalry resulting in Mosby loosing the element of surprise and suffering the loss of six men—his greatest defeat.
Mr. & Mrs. Jeffrey Edling, who initiated the effort to get the marker placed, were given the honor of unveiling the marker. Jeff Smith, a Mosby re-enactor, then read the text to the marker for those in attendance. The ceremony ended with Connie Boudreau giving the benediction. Members of the Clinton Hatcher Camp of the Sons of Confederate Veterans were on hand as an honor guard. Following the ceremony, everyone was invited by the Edling’s to their house, which served as Cole’s headquarters, for a reception.
Mosby’s biography is here, along with a photo.
[I wonder if the marker mentions if he owned slaves?]
