George Vere Benson, Dictionary of National Biography… (1885)
“ The king's displeasure soon passed away, and Sir John gave ample proofs of his devotion to the king by his liberal contributions to the royal treasury, and still more by the stubborn resistance offered by his castle long after all the neighbouring strongholds had fallen into the hands of parliament. The heroic defence of Corfe Castle by Lady Mary Bankes [q. v.] during nearly three years, against great odds, to which she yielded only when betrayed, is one of the brightest spots in that gloomy period. ”
