John Mainwaring John Mainwaring John Mainwaring (1724–1807) was an English theologian and the first biographer of the composer Georg Friedrich Händel in any language. He was a Fellow of St. John's College, Cambridge, and became rector of the parish of Church Stretton, Shropshire, and, later professor of Divinity at Cambridge. In 1760, one year after Handel was buried in Westminster Abbey he published anonymously a biography 'Memoirs of the Life of the Late George Frederic Handel'. More than half of this biography is focused on the years before 1712, when Handel moved to London. Therefore, it is supposed he received information from
Captain Mainwaring independently, although not always with the best of results. In "A Man of Action", Walmington is cut off when a bomb damages the railway and waterworks. Mainwaring imposes martial law and takes power from the Mayor. Under his law people need permits to take a bath and looters will be shot. He changes position when this power is taken from him by an official from GHQ, describing such an act and the imposition of martial law as "monstrous". Mainwaring often claims to know something, only to be proven wrong almost immediately. Men under him, however, are mostly devoted to him.
