He was largely a hack writer, working for Edward Dilly, and he padded his credentials with a bogus M.A.
In the leading case Entick v Carrington of 1765 he won a legal victory as plaintiff that defined the limits of executive power in the view of the English judiciary.
In 1755 he agreed with John Shebbeare and Jonathan Scott to write for their anti-ministerial paper, The Monitor, appearing every Saturday, at a salary of £200 a year; and his attacks on the government[1] caused his house to be entered and his papers seized under a general warrant in November 1762.
He published in 1757 a New Naval History, with lives and portraits, dedicated to Admiral Edward Vernon.
He left a large work, in four volumes, The Present State of the British Empire, helped by other hands, nearly ready, which was brought out in 1774.
