Captain John Hardy Jackson received a
letter of marque on 14 October 1805.
Sinclair was also carrying Captain
William Bligh, who was sailing to the colony to assume the governorship. Captain Bligh and Commander Joseph Short of
Porpoise disagreed continually through the voyage as each believed they were in charge of the convoy. When Bligh ordered a change of course for
Sinclair, Short responded by ordering first officer John Putland to fire warning shots at
Sinclair, which carried Putland's wife,
Mary, and his father-in-law, Captain Bligh. In great distress, John Putland complied with the order, firing two warning shots across the bow of
Sinclair. When
Sinclair did not immediately return on course, Short contemplated firing on
Sinclair. Fortunately,
Sinclair shortly afterwards corrected her course and he did not have to order Putland to fire. When the convoy arrived in
Port Jackson on 6 August 1806, Bligh assumed the governorship of the colony.
Sinclair left Sydney on 12 September 1806 with a cargo of oil and 14,000 seal skins for China.
Sinclair and Captain Jackson left
Whampoa anchorage on 3 January 1807. She reached Penang on 25 January and
St Helena on 18 April, before arriving at
The Downs on 3 July.
Sinclair made a second voyage to Australia, still under Moore's command. She arrived at Sydney on 28 July 1808, carrying Lieutenant-Colonel
Joseph Foveaux, the new Lieutenant Governor of the colony, and 45 troops. She left on 26 October for England.
Sinclair continued to trade under a letter of marque for some time thereafter. Captain George Allen received a letter of marque on 16 April 1811. Captain John Peat received a letter of marque on 4 January 1813. ==Notes==
