Terry- My apology. According to WC Whittle, Jr., "At 10 a.m., November 6, 1865, the last Confederate flag was hauled down, and the last piece of Confederate property, the C.S.S. Shenandoah was surrendered to the British nation, by letter to Earl Russell, from Captain Waddell, through Captain Paynter, R.N., commanding H.M.S. Donegal."
