Back in North America he raised a regiment in Nova Scotia of which he was made Colonel in 1803. In 1806 he was posted as a Brigadier to the Cape of Good Hope, from where he was next sent to India. He was again captured en route to Calcutta and spent two months in captivity before being exchanged. Safely in Calcutta as the second-in-command he took part in the conquest of Java in 1811, during which campaign he was assisted by his son George Wetherall. He returned to England in 1815 and in 1837 was promoted General and made Colonel of the 62nd Regiment of Foot. In 1840 he transferred as Colonel to the 17th (Leicestershire) Regiment.
