## Issue with Privateers

During the American Revolution an order was given to seize all ships and vessels of the Thirteen-Colonies. This led to an increase of privateering and illegal privateers used by foreign powers and other British Colonies alike to still trade with the rebellious colonies. Vice-Admiral James Young who was commander-in-chief in the Leeward Islands Station made the decision to treat illegal privateering as piracy and seize any vessels without the proper commission.
In 1777, Captain Thomas Dumaresq who commanded HMS Portland, the flag-ship of Vice-Admiral James Young was involved in an incident where the Portland seized the Hammond, a privateering ship from British Antigua. Due to the tribunal of the Court of Vice-Admiralty at Antigua declaring the privateers as legal, The owners of the Hammond had Vice-Admiral James Young and Captain Thomas Dumaresq arrested for the seizing of their ship and the impressing part of the crew. Young wrote to John Montagu, 4th Earl of Sandwich who was First Lord of the Admiralty to get clemency for both him and Dumaresq. However, King George III would tell Lord Sandwich to resolve the matter quickly while not provoking the privateers due to the outcome it would have with neighbouring powers.
On 3 June 1777 Dumaresq was found guilty of impressment by the Court of Common Pleas of Antigua and had to pay £950 what is approximately £160,000 in today's currency. To Dumaresq's luck, Lord Sandwich brought forth the government's plan to deal with the issue of illegal privateering altogether. Privateer Commissions would be granted by the colonial governors to all current illegal privateers and them would be able to keep their prizes they have already taken. The only condition was that all charges against all naval officers were dropped. If Dumaresq's charges were not dropped it could have had distress effects for the navy that could result in a reluctance of naval officers to sign-on new seamen due to fear of being charged with of impressment.
