In 1715 Steuart commanded a squadron on the west coast of Scotland engaged in helping the military to round up the rebels, but his next twenty-five years were passed in complete obscurity.
In 1747 Steuart wrote to Henry Pelham and the Duke of Bedford, then the first lord of the Admiralty, about his prospects of re-election. ‘The state of affairs is this’, Pelham explained to Bedford:
Mr. Dodington and I have agreed to nominate two persons each; Mr. Dodington would not name Mr. Steuart for one of his, and I did not see the necessity of my naming him for one of ours. Dodington, therefore, made the best excuse to him he could, and I must own, in my sense, not an improper one. For during these three or four years Mr. Steuart has had a command at Portsmouth which has kept him from attending Parliament as much as if he had been in the West Indies; besides, to whom does he belong? Not to your Grace, otherwise than as his profession obliges him; and as to your humble servant I have no knowledge of him but what was acquired by House of Commons acquaintance.
Bedford Corresp. i. 216.
Steuart did not obtain a seat. He died 30 Mar. 1757, having risen by seniority to the post of commander-in-chief of the fleet.
