The attempted arrests were a fatal mistake and the armed violation of Parliament turned many against Charles. He could no longer dissolve Parliament due to the passing of the Triennial Act. Fearing reprisals, on 10th January the King fled Whitehall by barge, together with Henrietta Maria, the twelve-year-old Charles (the future Charles II), and ten-year-old niece Mary. They arrived at Hampton Court without warning and spent the first night huddled together because the royal apartments had not been heated. The other royal children, James, Elizabeth and Henry, remained at St. James’s Palace. Henrietta Maria and Princess Mary subsequently left for safety in the Netherlands.
The five MPs came out of hiding in London and travelled to Westminster by boat in triumph. The King moved on to Greenwich where he was joined by Prince Charles. From there the King and his son travelled north to raise an army. Archbishop Laud remained incarcerated in the Tower of London until 1644 when he was brought to trial by Parliament and sentenced to death. He was beheaded on Tower Hill in January 1645.
