Ambrose was arrested four times during his travels and released without charge. King Charles I signed a proclamation on 7 March 1641, which decreed that all priests should leave the country within one calendar month or face being arrested and treated as traitors, resulting in imprisonment or death. Ambrose's parishioners implored him to flee or at least go into hiding but he refused. Their fears were compounded by a recent stroke which had resulted in the 56-year-old priest being partially paralysed. "Let them fear that have anything to lose which they are unwilling to part with", he told them.
