Wolseley continued to serve on Sir Hope Grant's staff in Oudh, and when Grant was nominated to the command of the British troops in the Anglo-French expedition to China of 1860, accompanied him as the deputy-assistant quartermaster-general. He was present at the action at Sin-ho, the capture of Tang-ku, the storming of the Taku Forts, the Occupation of Tientsin, the Battle of Pa-to-cheau and the entry into Peking (during which the destruction of the Chinese Imperial Old Summer Palace was begun). He assisted in the re-embarkation of the troops before the winter set in. He was Mentioned, yet again, in Dispatches, and for his services received the medal and two clasps. On his return home he published the "Narrative of the War with China" in 1860. He was given the substantive rank of major on 15 February 1861.
