He served under Sir Edward Pakenham as chief engineer during the War of 1812. He went on to act as official advisor to Lord Raglan during the Crimean War advocating the Bay of Kalamita as the point of disembarkation for allied forces and recommending a Siege of Sevastopol from the south side rather than a coup de main, so consigning the allied forces to a winter in the field in 1854.
