On 2 May1643, during the absence of her husband she bravely defended Wardour Castle for nine days with only herself, her children, a few maid-servants, and twenty-five men against thirteen hundred men and artillery commanded by two Parliamentary officers, Sir Edward Hungerford and Colonel Edmund Ludlow. She finally was forced to surrender but on her husband's return the parliament forces were soon dislodged.
