His lordship having no more business at court, and being unwilling to expose himself further to the machinations of his enemies, thought proper to retire to the country, where he remained quiet till he received his Majesty’s orders to revisit Hull:  Tho’ this order came at twelve o’clock at night, yet such was his unshaken loyalty and affection, that he went directly, and tho’ forty miles distant, he entered the place with only three or four servants early the next morning.  He offered to his Majesty, says Clarendon, to have secured for him that important fortress, and all the magazines that were in it; but instead of receiving such a command, he had instructions sent him to obey the orders of the Parliament, who suspecting his principles not to be favourable to the schemes of opposition then engaged in, called him to attend the service of the house; and some disaffected members formed a design to have attacked him, but his character being unexceptionable, their scheme proved abortive, and he had leave to retire again into the country.  This he willingly did, as he saw the affairs of state hastening to confusion and his country ready to be steeped in blood, and sacrificed to the fury of party.  But when the opposition rose high, and it would have been cowardice to have remained unactive, he embraced the royal cause, accepted a commission for raising men, to take care of the town of Newcastle, and the four adjoining counties, in which he was so expeditious and successful, that his Majesty constituted him general of all the forces raised North of Trent; and likewise general and commander in chief of such as might be raised in the counties of Lincoln, Nottingham, Chester, Leicester, Rutland, Cambridge, Huntingdon, Norfolk, Suffolk, and Essex, with power to confer the honour of knighthood, coin money, print, and set forth such declarations as should seem to him expedient:  of all which extensive powers, tho freely conferred, and without reserve, his lordship made a very sparing use; but with respect to the more material point of raising men, his lordship prosecuted it with such diligence, that in three months he had an army of eight thousand horse, foot, and dragoons, with which he marched directly into Yorkshire; and his forces having defeated the enemy at Pierce Bridge, his lordship advanced to York, where Sir Thomas Glenham, the governor, presented him with the keys, and the earl of Cumberland and many of the nobility resorted thither to compliment, and assist his lordship[5].

In the course of this civil war, we find the earl of Newcastle very successful in his master’s service; he more than once defeated Sir Thomas Fairfax the general of the Parliament, and won several important forts and battles; for which his Majesty in gratitude for his services, by letters patent, dated the 27th of Oct. 1643, advanced him to the dignity of marquiss of Newcastle; and in the preamble of his patent, all his services (says Dugdale) are mentioned with suitable encomiums.
