Although in some respects unsuited to the responsibility, Tweeddale was acknowledged as the leader of the Squadrone Volante (or Squadrone for short). By the time of the Union, however, he had become an armchair general, and in the Parliament of Great Britain he tended to watch from a distance while the next generation did the hard political work. His greatest strength was the reputation he cultivated as a man of principle, who took office reluctantly and only for the public good (even if this was not always strictly true); but he lacked an instinctive understanding of the political scene, could be indecisive, and was sometimes liable to ‘pets’ if he did not get his way.
never obtained any other character than that he was a well-meaning but simple man; and I have the charity to believe, he was forced against his will by his friends and those he trusted (who made a mere tool of him) to enter into many of the bad measures he pursued: so I may safely say, he was the least ill-meaning man of his party, wither thro’ inclination or capacity.Lockhart Pprs. i. 97.
Tweeddale’s family background was Presbyterian, of a moderate stripe. His grandfather was an ‘Engager’, while he and his father were both active in local government under Charles II. As Lord Yester, he commanded a militia regiment against Argyll’s uprising in 1685, and supported James II’s government on the Scottish Privy Council. Having adapted to the Revolution, he and his father reinvented themselves as Williamites: the family, however, had relatively little political interest and so Yester was sent to London by his father in December 1688 to wait on the prince of Orange and cultivate contacts with English politicians.
Two years passed before there was a revival in Tweeddale’s fortunes, during which time father and son intrigued against the administration of the Melvilles and flirted with radical Presbyterian critics of government.
On his return to Scotland Yester was chosen as one of the directors of the Company of Scotland, and in that capacity was closely involved in the ill-fated attempt to establish a Scottish colony on the Isthmus of Panama at Darien, which brought the Company into direct conflict with the interests of English chartered companies and heightened his own estrangement from William’s government.
Presumably because of his recent history of opposition, Tweeddale was not named as one of the Scottish commissioners to treat for a union with England in 1702. He continued in opposition, and was one of the more obdurate of the country party leaders in refusing to have any dealings with the head of the court party, James Douglas, 2nd duke of Queensberry [S].
The experiment, though, proved a disaster. During the session which began 11 July 1704, with Queensberry standing aloof, Tweeddale was comprehensively outmanoeuvred by his former country party allies.
Despite their failure in managing parliament, Tweeddale’s followers were given a sheaf of places in government, he himself becoming lord chancellor. The following year he asserted that he had taken office reluctantly and only to serve the queen.
To make sure that the Scots responded by appointing commissioners to negotiate a union, John Campbell, 2nd duke of Argyll [S], was chosen as commissioner to the Scottish parliament that was to meet in 1705. Tweeddale, who was already disconcerted by attempts to reconstruct the ministry and had refused to switch offices to become president of the council, at first refused to pass Argyll’s patent.
For his part, in the parliamentary session of 1705, Tweeddale was a relatively unobtrusive, though not entirely silent, presence. He was not appointed to the union commission the following year even though his support for the project had been made explicit by January 1706.
Tweeddale did not join his Squadrone colleagues Roxburghe and Marchmont on their journey to London in April 1707, and was still in Scotland at the beginning of August, when Roxburghe informed him that the queen had ‘asked me twice about your Lordship’s coming up.’s
Tweeddale did not stand in the 1708 election, though he attended and voted his party’s line.
Tweeddale died on 20 May 1713 at Yester House, reportedly ‘of a fall’, and was buried at Yester.
