In 1744 Lord Strathallan sent his younger sons Robert and Henry as apprentices to his brother Andrew Drummond the London banker.
In 1770 he succeeded his cousin John Drummond as partner of Thomas Harley in the contract for army remittances to North America;
Henry Drummond was a member of an intimate social group, known as ‘The Gang’, which included Anthony Chamier, Lord Frederick Campbell, Thomas Bradshaw, Rigby, Thomas Harley, Sir John Sebright, William Amherst, and R. M. Keith. Drummond, who looked after Keith’s financial affairs, wrote to him, 18 Oct. 1774:
We had a busy time lately by the dissolving of Parliament ... I ... tried to keep up a family interest at Northampton where I offered to have paid Lord Northampton’s debts amounting to about £3,000 and would have given the town as far as £1000 more towards paving their town and some public work, but would not give a guinea to individuals ... I ... told them I never should think a family interest worth preserving that was to be bought by money ... found it would not do without money, therefore gave it up immediately ... Things at present bear but a gloomy aspect with regard to North America ... I daresay it will all come right but it is disagreeable in the operation.
In December 1774 Drummond purchased a seat at Wendover from Lord Verney. An intimate friend of Lord Suffolk, he consistently supported North’s Administration, and on 3 Mar. 1775 wrote to Keith:
Yesterday I spoke to his Lordship, when he assured me he considered your business as an obligation that he was bound to pay ... Although it is not the most agreeable thing to be constantly boring a great man ... I shall continue to do it till I procure payment of the principal and interest ... I have no heart to write to you about politics, we are not only shamefully beat by the surrender of Burgoyne, but the panic has I think seized us here and we are now undoing ... by giving up taxation, the very object of the war and ... inviting a French war rather than avoiding it by the pusillanimity of our parliamentary conduct.
And again, 3 Apr. 1778:
The despair of the country with all ranks of men has been such ... that exceed all belief ... Stocks have sunk to a price unknown in this country ... want of confidence and opinion has produced the whole; ... there is nothing so dangerous for a Government as to be wavering ... How all this is to end God knows ... some change of consequence must take place.
In June 1778 Harley and Drummond secured a renewal of their contract for North America, and in August an extension to the West Indies, if required.
I had a full and explicit conversation with the Great Man upon the old subject of the debt which he is indebted to us, for I will still keep him to that ground that it is an affair between us and him, and I must own, provoked and angry as I have been with him ... he did show an honest and I think sincere feeling for the great loss you have sustained and once more assured me some steps would be immediately taken for the payment of the money.
Still, he did not trust even specific promises by North concerning repayment till assured by ‘the confidential secretary’ that he could depend on its being done.
At the general election of 1780 Drummond purchased a seat at Midhurst ‘at Lord North’s recommendation’.
Rigby wrote to Keith, 21 Jan. 1781:
I live much and in great cordiality with the Drummonds who are the best people in the world. I tell Bob he is of the party I describe, an opposition to the Opposition, which is his case. Harry is a better courtier, for he has one of the best contracts that ever man had and I rejoice that it is so.
Profitable it may have been, but at times the two partners felt uneasy when they had to advance money to the Government; still, they retained the contract till the end of the war.
The Drummonds were also very big subscribers to Government loans, but how much they subscribed for themselves and how much for clients cannot be established. When on 26 Mar. 1781 Savile made a motion concerning the recent loan, its terms and distribution, George Byng stated that while ‘Mr. Drummond’s house is put down for £84,000’ (unexpectedly little seeing their credit character), subscriptions in the names of their clerks—the list was read out by him—‘stood to the amount of £438,000’.
Drummond supported North till his fall, voting in every division for which a list is extant; voted with North against Shelburne’s peace preliminaries, 18 Feb. 1783; but was absent from the divisions on Fox’s East India bill. Friendly with Henry Dundas,
He died 24 June 1795.
