Bentinck joined the Coldstream Guards on 28 January 1791 at the age of 16, purchasing an ensign's commission. He was promoted to captain-lieutenant (lieutenant) in the 2nd Regiment of Dragoons on 4 August 1792, and to captain in the 11th Regiment of Light Dragoons on 6 April 1793. He was promoted to major in the 28th Foot on 29 March 1794 and to lieutenant-colonel in the 24th Dragoons that July. On 9 January 1798, Bentinck was promoted to colonel.
In 1803 he was nominated governor of Madras, where he quarrelled with the chief justice, Sir Henry Gwillim, and several members of his council.
The sepoy mutiny at Vellore in 1807 led to his recall.
His name was considered at this time for the post of governor-general, but Lord Minto was selected instead; and it was not until twenty years later that he succeeded Lord Amherst in that office.
It was on this last subject that Lord Macaulay's famous minute was written.
See Demetrius C. Boulger, Lord William Bentinck, in the " Rulers of India " series (1892).
Bentinck married Lady Mary, daughter of Arthur Acheson, 1st Earl of Gosford, on 18 February 1803. The marriage was childless.
