Two vessels of the Royal Navy have borne the name, HM galley Pigot. Both were acquired in 1778 during the American Revolutionary War, and both were lost that year; her crew destroyed the first to avoid her capture, and the Americans captured the second. Both were named for General Sir Robert Pigot, the general commanding the British Army at Newport, Rhode Island, during their service there.
On 16 May 1778, Pigot, (or Pigott) took her station in the Seconnet. Pigot was the former tender, Lady Parker, a schooner, that had been fitted out as a galley. The British at Newport now had three galleys, Alarm, Pigot, and Spitfire. They also had a new galley equipping. Earlier, Lieutenant (and future admiral and baron) James Saumarez had commanded Lady Parker for some months until 17 February 1778, when he had been given command of Spitfire.
Lieutenant Sir Henry Edwin Stanhope, of Nonsuch, was appointed to command the Pigot galley. On 25 May, the British launched the two-pronged Warren and Bristol raid. Pigot supported one division, which went up Warren Creek, where they succeeded in surprising and capturing an armed galley.
Five days later, 100 men of the 54th Regiment of Foot embarked on boats to attack saw mills at Fall River, Massachusetts. Pigot and some armed boats were to provide support. Pigot grounded, but the attack proceeded anyway. A sharp skirmish ensued when the troops arrived at their objective. Even so, they were able to destroy one saw mill and one grain mill, as well as a large stock of planks and boards, other buildings, some cedar boats, and so on. They then withdrew, having lost two men killed and five officers and men wounded. As the tide returned, Pigot was floated off, but as Flora towed her off, Flora lost two men killed and a lieutenant severely wounded.
