The defeated Cavalier escaped from the field of battle, and, like a true descendant of William the Conqueror, disdaining submission, threw himself into his own castellated mansion, which was attacked and defended in a siege of that irregular kind which caused the destruction of so many baronial residences during the course of those unhappy wars.
Martindale Castle, after having suffered severely from the cannon which Cromwell himself brought against it, was at length surrendered when in the last extremity.

Sir Geoffrey himself became a prisoner, and while his liberty was only restored upon a promise of remaining a peaceful subject to the Commonwealth in future, his former delinquencies, as they were termed by the ruling party, were severely punished by fine and sequestration.
But neither his forced promise, nor the fear of farther unpleasant consequences to his person or property, could prevent Peveril of the Peak from joining the gallant Earl of Derby the night before the fatal engagement in Wiggan Lane, where the Earl's forces were dispersed.

Sir Geoffrey having had his share in that action, escaped with the relics of the Royalists after the defeat, to join Charles II.

He witnessed also the final defeat of Worcester, where he was a second time made prisoner; and as, in the opinion of Cromwell and the language of the times, he was regarded as an obstinate malignant, he was in great danger of having shared with the Earl of Derby his execution at Bolton-le-Moor, having partaken with him the dangers of two actions.

But Sir Geoffrey's life was preserved by the interest of a friend, who possessed influence in the councils of Oliver .-- This was a Mr.Bridgenorth, a gentleman of middling quality, whose father had been successful in some commercial adventure during the peaceful reign of James I.; and who had bequeathed his son a considerable sum of money, in addition to the moderate patrimony which he inherited from his father.
The substantial, though small-sized, brick building of Moultrassie Hall, was but two miles distant from Martindale Castle, and the young Bridgenorth attended the same school with the heir of the Peverils.
