He was taken prisoner at Fort Washington early in the war and spent several years aboard a prison hulk. After independence, Lingan served as a government official in Georgetown. At the outbreak of the War of 1812, Lingan was an outspoken advocate of freedom of the press and was murdered by a mob while defending the offices of an anti-war newspaper in Baltimore.
