Sir William Earle now tried to starve the castle into a surrender. Lady Bankes affected a wish to treat for the surrender of the guns; but her real object was, that the besiegers, relaxing in their careful blockade, would give greater facilities for introducing fresh supplies to the garrison. The event justified her hopes. She also obtained the help of Captain Lawrence, commanding a company of Royalists.
The Puritans, about six hundred in number, assaulted the castle, and endeavoured to carry it by a coup de main. But the brave little garrison, sallying forth, drove away the besiegers and brought back nine oxen. Again the besiegers tried to take the castle by storm. Dividing their forces, one party attacked the middle ward, which was defended by Captain Lawrence and his company, while the other division assaulted the upper ward, held by Lady Bankes with her daughters, her female servants, and five soldiers, who hurled down huge stones and red-hot coals on the heads of the storming party. At last, after losing one hundred men in the assault, the Parliamentary forces retreated from before Corfe Castle. The blockade had lasted, altogether, six weeks.
Lady Bankes lived to see the Restoration, and died in April, 1661. She was interred in the south aisle of Rislipp church. The following inscription was placed upon her monument by her eldest son:—
"To the memory of
"The Lady Mary Bankes, the only daughter of Rafe Hawtrey, of Rislipp, in the County of Middlesex, Esquire, the wife and widow of the Honourable Sir John Bankes, Knight, late Lord Chief Justice of his late Majesty's Court of Common Pleas, and of the Privy Council to his late Majesty King Charles the First, of blessed memory; who, having had the honour to have borne, with a constancy and courage above her sex, a noble proportion of the late calamity, and the happiness to have outlived them so far as to have seen the restitution of the government, with great peace of mind laid down her most desired life the 19th day of April, 1661. Sir Ralphe Bankes, her son and heir, hath dedicated this. She left four sonnes—first, Sir Ralphe; second, Jerome; third, Charles; fourth, William (since dead, without issue); and six daughters."
The Earl of Derby was one of the most prominent Cavalier leaders. In 1643, while awaiting a siege at Lathom House, Lancashire, his family mansion, the earl received intelligence that Parliament had despatched troops to annex his miniature kingdom, the Isle of Man. Wishing to preserve the island as a final retreat for his royal master, in case of misfortune overtaking him, he left Lathom House in charge of Charlotte, his countess, and set off to the Isle of Man.
On the 27th of May, 1643, Mr. Holland, governor of Manchester, despatched a messenger to Lathom, commanding Lady Derby either to subscribe to the propositions of Parliament or surrender the mansion. She refused compliance with either alternative; and for nearly a year contrived, though closely blockaded, to keep the enemy from coming to open hostilities. At last, on the 24th of February, 1644, Parliament despatched three colonels to Lathom House. Before their arrival, the countess hastened to lay in provisions and ammunition, and to arm a sufficient number of retainers to serve as a garrison.
The countess determined not to surrender on any terms, and rejected every proposal. "Though a woman," said she, "and a stranger divorced from her friends and robbed of her estates, she was ready to receive their utmost violence, trusting in God for protection and deliverance."
Hostilities having commenced, the Parliamentary army pushed the siege with great vigour. The countess conducted the defence in person; but, though she took the office of commander, she was not unmindful of the spiritual welfare of her people. She was present four times a day at public prayer, attended by her little daughters, Catherine and Mary.
