The siege and capture of Bristol by Parliamentary forces on 10 September 1645 was one of the most devastating blows to the Royalist cause during the English Civil Wars (1642-1651). King Charles I of England (r. 1625-1649) had entrusted the city's safekeeping to his nephew Prince Rupert (1619-1682), but he could not hold out against the New Model Army led by Sir Thomas Fairfax (1612-1671).
