Gordon was born in Jamaica of Aberdeenshire parents, cousins of the Gordons of Hallhead. At Leyden he was a fellow student of Charles Townshend, John Wilkes, James Johnstone, William Dowdeswell and Alexander Carlyle, but was ‘too young and too dissipated’ to attend their serious discussions.
Bon viveur, rake, and humorist, he was an intimate friend of Lord Sandwich who in 1764 appointed him envoy to Ratisbon. Despite his ribald comments on his own mythical qualifications, Gordon ‘really liked the trade he had taken by the hand’, and was anxious to earn the approval of his patron, who early in January 1765 offered to obtain his transfer from Ratisbon to Copenhagen.
In England in 1776 he married a wealthy widow whose first husband had left her £7,000 a year and all his estates for life. He wrote to Sandwich, 13 July 1776:
Will Suffolk, will North, force me to quit this charming abode? ... Before I left town I swore to them both I would not after 14 years banishment be thrown aside like an old slipper; reste à voir what they will do for me.
Ibid. 13 July 1776.
Hearing that Peter Taylor was dying, he urged Sandwich in July to carry out his friendly intentions and ask North for the Government interest at Portsmouth. But Taylor did not die; and Gordon wrote to Sandwich, 26 Sept. 1776:
I have adhered to the advice that both you and Weymouth gave me, which was not to give up my post, but always to say I was ready to go abroad, for if I once gave it up without getting something I should be sur le pavé ... But one thing is very clear to me that my Principal will either make me resign or go abroad very soon unless my friends interfere and save me.
A few days later he was officially informed that he was destined for Sweden; but managed to avoid the Swedish appointment; seems to have returned for a time to Brussels; resigned in 1777; and on Taylor’s death entered Parliament.
Long hostile to ‘those canting hypocritical rebellious scoundrels of Bostonians’,
Governor Johnstone ... called on Sir William Gordon ... who had been in America, to testify that the Americans had not formerly thought of making themselves independent. Sir William, a man of very blundering head, thus unexpectedly called on, had one of those momentary inspirations which sometimes light on idiots ... and ridiculed him with much humour, wondering that the Governor who so boldly attacked the highest personages, should descend to him.
Gordon remained closely attached to Sandwich, reporting to him parliamentary gossip and trends of opinion, but by the end of 1779 had lost faith in North, who had disregarded his claims for preferment. He wrote to Sandwich, 18 Jan. 1780:
I am no stranger to the views of the Opposition ... They are dangerous to particulars, they are dangerous to the Constitution ... It is now therefore become the duty of every man in the community to stand forth and counteract their schemes. But, my dear Lord, can a few Members in the House of Commons do this without a leader that is active, resolute, and decisive? Has Lord North a friend in office (one or two excepted) that is not lukewarm in his cause? Will his Majority of Mutes save him ... He must alter his conduct or he must sink himself and those that are joined with him. I will say nothing with regard to his behaviour to me; you have called upon me and I will most certainly be in town at the meeting of Parliament, and when there will give him all the active assistance I can, for I cannot act a lukewarm part. But I will be candid and honest to declare that the first Member of the House of Commons that kisses hands I shall ask for the Chiltern Hundreds.
Sandwich sent this letter to Robinson, who replied 22 Jan. 1780:
Sir William Gordon is impatient, indeed too much so, for impatience might defeat the best intentions which are held for him. I return you his letter because I think it would injure him to show it to our friend.
Gordon continued to support Administration, and in 1780 was returned again on the Government interest for Portsmouth. On 5 Sept., a few days before the election, he received the lucrative place of clerk comptroller of the Green Cloth, and his loyalty to North was assured. He spoke, 20 Nov. 1780, against the vote of thanks to the former Speaker, Sir Fletcher Norton,
Under the new Administration Gordon’s place was abolished. In August 1782 he had several conferences at Buxton with Loughborough, whose scheme for a Fox-North Coalition he approved, but thought impracticable. Loughborough reported to William Eden that Gordon held Shelburne ‘in great contempt’ and believed that ‘the country gentlemen ... bitterly repented their folly and would rally under Lord North’s standard if he would set it up’.
Gordon voted against Shelburne’s peace preliminaries, 18 Feb. 1783, and supported the Coalition. In July he vacated his seat so that the Coalition might bring in Thomas Erskine. His price was a pension ‘on the foreign ministers’ list’ of £1000 p.a., and although the King was believed to be unwilling to grant it, the warrant was passed 17 Oct. 1783.
Gordon retired to Garendon where he and his wife were active enclosers and, taking full profit from their liferent possession, cut down trees to the value of £9,500, which they invested for their own benefit.
Gordon died 26 Jan. 1798.
