Once in Federal hands, Jamestown became a meeting place for runaway slaves, who burned the Ambler house, an eighteenth-century plantation house, which along with the old church was one of the few remaining signs of old Jamestown.
Etter at stedet kom i føderale hænder blev Jamestown et mødested for bortrømte slaver, som nedbrænte Ambler-huset, en plantage fra det 18. århundrede som sammen med den gamle kirke var de få tilbageværende tegn på Jamestown.
