A few days after the opening of the siege, Sir Thomas Fairfax, the Parliamentary general, received a letter from the Earl of Derby, in which the latter, dreading the extremes to which his wife and children might be reduced, requested for them a free pass through the camp of the besiegers. When this was communicated to the countess, she thanked Sir Thomas for his courtesy in forwarding the missive; but replied that "she would willingly submit to her lord's commands, and therefore willed the general to treat with her; but till she was assured that such was his lordship's pleasure, she would neither yield up the house nor desert it herself, but wait for the event according to the will of God." She forwarded a similar message to her husband at Chester. On the 25th of April, Colonel Rigby despatched a peremptory message, demanding the surrender of Lathom House immediately. The countess refused: and the siege was prosecuted with renewed vigour; while the garrison, animated by the presence of Lady Derby, continued to defend the house with unabated courage. At last, on the 23rd of May, they learnt, to their inexpressible relief, that Prince Rupert and the Earl of Derby were in Cheshire, marching to their aid. When the Puritans heard of the approach of Prince Rupert, they retreated to Bolton. On the 29th, Prince Rupert "not only relieved, but revenged the most noble lady, his cousin," leaving one thousand five hundred of the besiegers dead on the field, and taking seven hundred prisoners. The next day he presented the countess with twenty-two of those standards which, three days previously, had been proudly waving before Lathom House. The countess and her children accompanied the earl to the Isle of Man, leaving the mansion in charge of Colonel Rawstone. The latter defended it till the following December, when the decline of the Royal cause obliged him to open negotiations with Fairfax. Before they were brought to a satisfactory conclusion, the house was treacherously surrendered by an Irish soldier. The earl and countess, in the midst of their devoted adherents in the Isle of Man, defied the threats of Parliament. The earl was one of the first to join the standard of Charles II. in 1651. Captured on the borders of Cheshire, he was carried to his own town of Bolton-le-Moors, where he was beheaded, October 15th. Misfortune never comes unaccompanied. The bereaved countess was betrayed, with her children, by a false friend, and thrown into prison. She regained her liberty at the Restoration; and for the rest of her life dwelt, with her remaining children, at Knowsley, near Lathom, where she died in 1663. * * * * *
