Campbell held commissions concurrently in the Royal Engineers and Fraser’s Highlanders, served in America and was wounded at Quebec. After the peace he gained great reputation as a military engineer and expert on fortifications,Fort William—India House Corresp. 1767-9(India Rec. Ser.), 97, 127; Bengal Council to Court, 28 Mar., 25 Sept. 1769, pp. 537, 580.
In 1774, encouraged by his friend Robert Preston, the East India captain, he stood for Stirling Burghs against the Lawrence Dundas interest, and by lavish use of his Indian wealth out-manoeuvred his opponents and was returned. Sir William Mayne estimated that for less than a third of his expenditure ‘he might have secured an English borough, giving the highest price’.
Appointed in November 1775 to command the 2nd battalion of Fraser’s new Highland regiment, he sailed for America in spring 1776, arrived in Boston harbour unaware of the British evacuation, was made prisoner, sent to Concord, and released on parole. When the British captured the American General Lee, Samuel Adams demanded that Campbell ‘be secured ... as one upon whom retaliation is to be made’. Campbell was then imprisoned in the common jail until released by Washington’s intervention, but remained captive until exchanged in May 1778.
Immediately resuming his command, he was appointed by Clinton in October 1778 to lead the expedition against Savannah and unite with Prevost’s southern force.
I am not without the hope of being the first officer to take a stripe and star from the rebel flag of Congress ... Your Lordship will see the necessity of sending out a governor immediately. I am merely a soldier and wish, when I can no longer render service to my Sovereign in that line, to retire from the bustle of public employ.
Leaving Prevost in command in Georgia, he sailed from Savannah in March and returned home a popular hero. While on leave in Scotland he proposed joining the Western Fencibles then raising. North wrote to the King, 30 Aug. 1779:
Lt.-Col. Campbell wishes to serve without pay with the irregulars and the new armed peasants, but Lord Amherst objects to it because he belongs to the army in America. Lord North ... wishes as a public man that Mr. Campbell’s talents, as they cannot in this instant be employed in America, might be made as useful as possible in Great Britain.
The King, however, agreed with Amherst, and by early 1780 Campbell was again out of the kingdom. At the general election of 1780 he stood down in favour of his brother James; soon afterwards was appointed lieutenant governor of Jamaica; earned high praise for his reorganization of the island’s defence;
On his return home he was knighted and appointed governor of Madras, through the friendship of Henry Dundas, who remained his constant correspondent and supporter to the end of his life.
I am astonished to hear that the court of directors seize every opportunity of attacking Sir Archibald Campbell ... Nothing ... could be more fatal to the British interest in India than his removal. He has shown great ability and the most perfect uprightness and integrity and possesses the esteem and confidence of the civil as well as the military part of the settlement.
Deeply hurt by the Company’s ‘illiberal treatment’,
He died 31 Mar. 1791.
