The town of Oswestry was now in the hands of the parliamentarians, under the temporary Governorship of Colonel Mytton, but was not long permitted to remain quietly in the power of the victors. Only one short week elapsed before a formidable attempt was made by part of the royalist army, under Colonel Marrow, a skilful and intrepid commander, to retake the town, and drive the parliamentary forces from their position. Colonel Marrow invested the town with 3,500 infantry, and 1,500 cavalry, and maintained a close siege for the three following days. This sudden assault greatly embarrassed Colonel Mytton, whose only hope for relief was from Sir Thomas Myddleton, his kinsman by marriage, who was then stationed at Knutsford, in Cheshire, more than fifty miles distant. Colonel Mytton, however, succeeded in making Sir Thomas acquainted with his position in less than twelve hours from the commencement of the royalist attack; and the gallant knight, who was heartily engaged in the parliamentary cause, immediately mustered three regiments, namely, Booth’s, Mainwaring’s, and Croxen’s, with Major Lothian at the head of the reserve, and marching onwards with all speed, reached in two days within sight of Oswestry—it is supposed between Halston and Whittington. During this interval of time the royalists had not obtained full possession of the town, though consisting, as Sir Thomas Myddleton says, “of the most valiant commanders and soldiers, drawn out of the garrisons of Chester, Cheshire, Shrewsbury, Shropshire, Ludlow, Denbighshire, Flintshire, and other places.” They had possessed themselves of the Church, but had made no inroad upon the Castle. Myddleton’s approach having been made known, Colonel Marrow marched out from the town, determined to attack him before his troops could recruit themselves after their long march. “They had taken the passage of water neere to Whittington,” says Sir Thomas, in his letter to Lenthall, the Speaker, “and very furiously assaulted and charged us, but were repulsed and forced to retire, through the courage of our horse, who most courageously entertained the enemy. Three several times the skirmish was doubtful; either side being forced so often to retreat. But in the end, our foot forces, coming up, relieved the horse, beat back the enemy, and pursued them with such force, that our horse being thereby encouraged, which indeed was formerly weary, joining with the foot, they put the enemy to an absolute flight, in which we pursued them five miles towards Shrewsbury, to a place called ‘Felton Heath,’ and where we remained after their flight, again masters of the field. In the skirmish with the enemy, and in the pursuite, we lost several of our horse, some of our troopers, but never a footman, which I am yet informed of. As for the enemy they lost several stout men; had many of them taken prisoners, some of them being of great quality, as the Lord Newport’s eldest son; and
