Forbes, who always suffered from poor health, was the eldest son of the East Indian agent and proprietor, Charles Forbes of Bombay, and lived his life almost entirely in his father’s shadow. Possibly born in India, he was sent to England in 1809, and educated in London under one Pearson.
In the House he was an almost entirely silent Member, who, when present, contented himself with copying his father’s independent line. He voted for Catholic relief, 6 Mar. 1827. He sided with opposition for inquiry into the allegations against the corporation of Leicester, 15 Mar., but divided in the majority for the duke of Clarence’s grant, 16 Mar. He made his only known speech, 22 Mar., on the mutiny at Barrackpoor, one of his father’s causes célèbres, when he
considered that the papers called for were absolutely requisite, to show whether a case of sufficient necessity really did arise, for the dreadful massacre in which, not only 160 of the native soldiers lost their lives, but many women and children residing in their huts were sacrificed also.
Like his father, he voted that day in the minority for the production of information on this. He divided against the Canning administration to consider separating bankruptcy jurisdiction from chancery, 22 May, but voted against the third reading of the Penryn election bill, 7 June. He also sided with ministers in favour of the grant to improve water communications in Canada, 12 June, but with Hume against the committal to Newgate of Thomas Flanagan on a charge of forgery, 19 June 1827. In the unusual absence of his father, he voted for repeal of the Test Acts, 26 Feb., Catholic relief (for which his father paired), 12 May, a lower pivot price for corn imports, 22 Apr., and to condemn chancery delays, 24 Apr. 1828. Unless it was his father (riding another of his hobby-horses), he spoke in praise of shipbuilding at Bombay, 19 May. (A second speech credited to ‘Mr. Forbes’ on 22 May was certainly one of his father’s.) In December 1828 he married the sister of a junior clerk at the board of control. Listed by Planta, the Wellington ministry’s patronage secretary, in February 1829, as likely to be ‘with government’ on the Catholic question, he voted for emancipation, 6, 30 Mar. He divided in the minority for allowing Daniel O’Connell to take his seat without first swearing the oath of supremacy, 18 May 1829. He paired in favour of Jewish emancipation, 5 Apr., and voted for it, 17 May 1830. He registered another of the votes which he cast unaccompanied by his father, 7 June 1830, when he joined the majority in favour of abolishing the death penalty for forgery.
Forbes was elected to the court of directors of the East India Company in April 1830, one of only two connections of agency houses to be so represented, but he was out by rotation until the following year.
He died at Ventnor, Isle of Wight, in December 1840, as a result of a ‘rapid decline’ caused by consumption. By his will, dated 30 May 1835 with one codicil, he left his library at Newe to his father, and the rest of his estate, which included personalty sworn under £9,000 in the province of Canterbury and at £5,092 in Edinburgh, in trust, to be divided among his children, who were all more or less consumptive.
