Cuninghame was closely connected with the Dorset family through his brother Robert. He served in America under Loudoun and Wolfe,
Here in February-March 1781 he initiated negotiations for the capitulation of the Dutch settlements at Demerara and Essequibo.
A governor writing on the ruins of a whole island levelled by the most fatal of all hurricanes, that his chief misery was the loss of what? his bracelets with the portraits of his idols—who would dare to bring such a revolting hyperbole on the stage?
Walpole to Lady Upper Ossory, 9 Jan. 1781; Cuninghame to Germain, 25 and 26 Nov. 1780, HMC Stopford-Sackvile, ii. 290-1.
In February 1781 the assembly’s charges against the governor came before the Board of Trade, who deferred consideration until receipt of Cuninghame’s statement in defence.
But Cuninghame remained intransigent, continued to levy the disputed fees, delayed sending his defence, and the case was not heard until 13 Apr. 1782, after the fall of North and shortly before the abolition of the Board of Trade. When Estwick suggested that, in the circumstances, ‘he supposed he should have no further occasion to trouble the Board’, Cuninghame’s counsel maintained that if there were no further proceedings, Cuninghame was entitled to an acquittal.
On his return home he settled in London. Although a supporter of North and the Coalition he, like his brother, went over to Pitt. He wrote to William Eden, 16 Dec. 1785:
His own precarious finances were improved by his appointment as colonel of his old regiment. Closely in touch with Irish as well as English political affairs and with the stock market, he kept Eden informed of events and opinions.
Opposition seem to be laying on their oars, thinking, I presume that they have a firm game to play. Our stocks fell one day for a quarter of an hour 3½ per cent upon the report that Mr. Pitt was determined to resign—a flattering circumstance I think for him.
His loyalty to Pitt over the Regency question was not put to the test. He died 10 Sept. 1788.
