Life
Thomas was born in 1729 to Jean Dumaresq and Ann Bokenham (niece of Captain William Bokenham), and was a member of the notable Dumaresq family of the Channel Islands.
He would obtain a commission as a lieutenant in 1755 and in 1763 he would obtain his first command, of the British Cutter, named the "Esther".
Thomas Dumaresq was promoted to Rear-Admiral in 1794, and a Vice-Admiral in 1795. On 1 January 1801, he was promoted to Admiral of the Blue.
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.

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 10, 2026. The linked authority identifier is Q105079127. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1729, 1802, 1755 and 1763.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
