Boscawen sat at Truro on his family interest, reinforced by his own distinction as sailor and his popularity with the families whose sons he took to sea with him. ‘Ready and decisive courage’ was deemed the distinguishing feature of his character.
Contrary to a tacit convention which for more than forty years had left the county representation of Cornwall uncontested to the Tory country gentlemen, in October 1753 Robert Hoblyn, a Cornish squire and mineowner, since 1742 M.P. for Bristol, decided to stand against the two sitting Members, John Molesworth and James Buller. Lord Edgcumbe strongly deprecated that move—‘the Tories irritated by the opposition are very likely to endeavour at revenge in some of the boroughs’ which so far were exceptionally quiet, and this ‘for the sake only of a person, by whom there will be nothing gained [Hoblyn himself was a Tory], but the Admiral answers for his love to the ministry’.
Many people (and I confess myself among the rest) expected that a fourth would have hoisted his flag. But I fancy he knew that if he did, he should be followed by but a weak squadron, besides very much endangering the interest of his confederate which ... is personally a strong one. All ... are ... much at a loss to see what will be gained by it ... Thomas Pitt ... urged that argument, which the Admiral answered only by saying, ‘that he liked the other better and that was reason sufficient for him to be for him.’
Apparently Boscawen was trying to make Hoblyn, the Tory, break through the traditional set-up in the county, reserving his own intervention to a future occasion. However, a week later Hoblyn withdrew his candidature.
‘But although this incident be sufficiently provoking, yet the affair of Mitchell is far more vexatious to me’, Lord Edgcumbe went on to say in his letter. Hardly in any other Cornish borough was the balance of electoral interests so complex and delicate as at Mitchell. Edgcumbe was as keen as the Boscawens to defend what he considered his due interest in the borough, but would have been satisfied with one candidate, Hussey, whom they had already nominated. But
Mr. Hussey’s counsellors have advised him rashly to propose a colleague one Mr. Lutterel, of whom I nothing know ... he owes this step to the wild advice of those heroes who set up Hoblyn.
There is a mass of conflicting evidence concerning the interplay of interests and schemes at Mitchell. But so much seems clear: that Boscawen, in his decisive manner, had with his two brothers George and John started there a canvass on 29 Aug. 1753, visiting ‘every house’,
In April 1755 Boscawen, in command of a squadron sailed for America, returning in November. Next, he commanded a squadron blockading Brest. He has been criticized for his part in the trial of Byng. But while there was little sympathy between the two, it is not clear that Boscawen did more than was incumbent on him as the senior member of the Admiralty Board, and its only sailor, barring Temple West, who had been Byng’s second-in-command at Minorca. In a letter to him on 4 Oct. his wife remarks: ‘I am vastly glad you have a scheme to avoid Byng’s trial’
In June 1757 Boscawen was placed once more in command of the fleet blockading Brest, but was soon recalled; expected to be employed on the expedition against Rochefort; but Knowles went as second-in-command to Hawke. There were rumours that Boscawen was dismissed, and that he was ‘extremely angry’.
He complains [wrote Jenkinson to Grenville on 4 Aug. 1757] that this is a private pique of Mr. Pitt’s, and assigns as the cause thereof his opposition to the navy bill; he talks in short like a man who has lost a good cruise, and wants to raise a disturbance.
Grenville Pprs. i. 203-4.
Walpole had a similar story to tell
But in October 1757 Boscawen was appointed second-in-command of the main fleet; and in February, as admiral of the Blue, sailed as naval commander of the expedition which captured Louisburg. On his return he received the thanks of the House of Commons, and was sworn a Privy Councillor. In April 1759 he sailed for the Mediterranean, and on 18 August won the victory of Lagos Bay over the French. On his return, he was appointed general of the marines, with a salary of £3,000 per annum.
At the height of his popularity and glory he now staged his second incursion into Cornish county politics. About the end of September 1760 there were rumours that he meant to stand for the county at the general election. Lord Edgcumbe, visibly disturbed, wrote to Newcastle on 28 Sept. that the admiral had not said a word to him about it although he had stayed with him two days during the past week; and while asking for the Duke’s views, reminded him of the line taken by Walpole and Pelham on similar occasions.
In fact, at the county meeting at Bodmin, on 10 Oct., Boscawen declared his candidature; and the next day wrote to Newcastle asking for his support;
I had the honour of your letter by the last post, with an account of Adm. Boscawen’s death: an event that greatly affects this county, there being a vast number of Cornishmen whose bread, and hopes of preferment depended entirely on him. The nation indeed must feel the loss of so great, so distinguished a commander, whose capacity, as well as courage enabled him to conduct naval expeditions better perhaps than any that are left behind him.
