Always at the centre of events, John Hewson first came to public attention as a fiery radical preacher in London in the 1630s. On the outbreak of the first Civil War in 1642, he joined the Parliamentary army. His personal bravery and forceful leadership soon won recognition and promotion, becoming one of the 'grim-faced colonels' whose regiment provided Cromwell's power base. His part in the trial and execution of King Charles I was torious, indeed it was to Hewson that Cromwell turned to find the headsman. Taking a prominent part in Cromwell's conquest of Ireland, he became Military Goverr of Dublin, enthusiastically carrying out the infamous transplantation of Irish landowners to the cold and barren west of the country. In the failing years of the Commonwealth, Hewson was one of the inner circle of military officers who attempted to govern the country. When they fell, he fell with them, ending his life in obscurity abroad. It is strange that the central role Hewson played in this fascinating period of England's story has been overlooked by historical authors. This book is perhaps the first full account of his life since the Reverend Mark Noble's Lives of the Regicides, written in the late eighteenth century. We believe that this extensively researched work provides a new resource for students of the period, but will also appeal to the more general reader.
