After the Second English Civil War, the leadership of the New Model Army felt deeply betrayed by the King because they thought that while they had been negotiating in good faith he had duplicitously gone behind their backs in making The Engagement with the Scots and encouraging a new civil war. In April 1648, the Grandees of the Army met for a three-day meeting in Windsor Castle. At the end of the meeting, the Grandees accepted that it was their duty "to call Charles Stuart, that man of blood, to an account for that blood he had shed, and mischief he had done".
