In early July 1776 the Roebuck along with three other warships, two tenders, and a row galley attempted to relieve the deposed Royal Governor of Virginia, Lord Dunmore, and his supporters and slaves. The former governor and his company were marooned on a fleet of vessels off the shore of St Georges Island in St Mary’s County. By the time the Roebuck reached Lord Dunmore’s party most were dead of disease. Lord Dunmore was rescued and ultimately returned to Great Britain. Meanwhile, short on fresh water, Roebuck and the vessels accompanying her sailed up the Potomac to replenish their supplies. Their destination was Sandy Point in the Nanjemoy area. The Roebuck’s captain, Snape Hammond, decided to harass and annoy the colonial “rebels” by landing at different places along the way.
