On September 28, 1863, Confederate Maj. John S. Mosby raided the house that stood nearby on the bluff at the end of May Boulevard after riding from Fauquier County with eight of his men toward Alexandria in an attempt to capture Francis H. Pierpont, provisional governor of the Restored Government of Virginia. Finding that Pierpont had gone to Washington City instead of remaining at the City Hotel, known today as Gadsby's Tavern, Mosby and his men burned a railroad bridge within sight of Forts Ellsworth and Lyon, then rode along Telegraph Road to the Rose Hill Plantation to surprise the governor’s aide, Col. Daniel F. Dulany. One of Mosby's Rangers, French Dulany, was Col. Dulany's son, and Anne S. Frobel, a Rose Hill neighbor, recorded in her diary that Mosby’s party came unexpectedly to Rose Hill and carried Col. Dulany off to Richmond despite a tense exchange between father and son. Dulany was imprisoned, exchanged, and survived the war, but his son was mortally wounded in 1864. The house burned in 1895.
