Lindsay was promoted to captain on 26 March 1813. He was appointed to command an artillery company and joined Major-General Bennett Marlay's division for the 1814 campaign of the Anglo-Nepalese War. Marlay's force entered the Nepalese Terai in November but otherwise carried out no significant action before it returned to the Dinapur Cantonment in May 1815. Lindsay remained with a detachment of troops left to guard the frontier.
