Macbride served with Keppel’s fleet during the American war, and in 1778 was present at the action off Ushant. Sandwich, in his list of ‘Officers of Admiral Keppel’s Fleet’ drawn up in November, wrote that he was ‘an exceedingly troublesome, busy, violent man, very bold but with very little understanding. Reckoned an active officer and much patronized by Admiral Keppel.’
In 1784 Macbride successfully contested Plymouth in opposition to the two Administration candidates. In the House he was an opponent of Pitt but voted for his parliamentary reform proposals, 18 Apr. 1785. He signed the third party circular, 1 May 1788. In 1785-6 Macbride was member of a commission to inquire into proposed increases in the fortifications of Plymouth and Portsmouth, and like other naval officers in the commission strongly opposed the scheme. When the proposals were debated by the House, he several times condemned them as ‘an idle waste of public money’, and on 14 Mar. 1785 said that ‘he thought it strange that in a business of such consequence to this country the advice of professional men had not been taken’.
Macbride unsuccessfully contested Plymouth in 1790, and died 17 Feb. 1800.
