In the early months of 1660 the taciturn West Country soldier George Monck held the fate of the British Isles in his hands. Oliver Cromwell was dead and the British republic had descended into chaos. The army and its leaders had ousted his son, Richard, and – once again – marched Members of Parliament out of their chamber in Westminster before bolting the door. Monck had been watching at a distance as army chief of Scotland. In the ensuing game of military and strategic chess, played for the future of the nation, he intervened as few had done before or since. Declaring his support for the expelled parliament, he marched south.
