The peace treaty was negotiated and drafted by Frederick Currie, assisted on military matters by Brevet-Major Henry Lawrence, acting under powers vested in them by Hardinge. Currie's diplomatic skills so impressed Hardinge that the British authorities rewarded him with a baronetcy in January 1847. On 11 March 1846, two days after signature of the Treaty, a supplement, comprising eight Articles of Agreement, was signed by the same parties. It provided that a British force would remain in Lahore until no longer than the end of the year "for the purpose of protecting the person of the Maharajah and the inhabitants of the City of Lahore, during the reorganization of the Sikh Army". This supplementary agreement was at the request of the Lahore Durbar. The Lahore army would vacate the City, convenient quarters would be provided for the British troops and the Lahore Government would pay the extra expenses.
