In 1860, James Bruce (1811–63), the eighth Earl of Elgin, embarked upon a second embassy to China which aimed to obtain ratification of the Treaty of Tientsin and finally conclude the Second Opium War on terms favourable to the British. Accompanying Elgin as his private secretary was the enterprising army officer Henry Brougham Loch (1827–1900). Originally published in 1869, Loch's first-hand account of the mission reflects sustained concern over Britain's strained trading relationship with China in the nineteenth century. Notwithstanding his views regarding the need for European influence to shape China's future success in government, his clearly written narrative illuminates contemporary diplomacy and the events surrounding the Convention of Peking in October 1860. Prior to this outcome, Loch had been captured, imprisoned and brutally tortured by Chinese officials. His chapters detailing this experience and his eventual release are especially noteworthy.
