The engagement was short and sharp. After a hot affair of about two hours, in which Lord Denbigh’s artillery played fiercely upon the garrison with small and great shot, a breach was made in the walls of the town, and the infantry poured in, headed by Major Fraser, with the loss of only one man killed and three wounded. “The New-gate,” adds Pennant, “was next demolished by the cannon, when a young fellow, one George Cranage, went with a hatchet, and cutting down the chains of the draw-bridge, enabled the cavalry also to enter. The besieged made an attempt to maintain the Church, but soon finding it untenable, fled to the castle. Hither they were closely pursued, and the pioneers were quickly called in to undermine its walls; in which, we are informed, the skill as well as valour of Colonel Mytton was very conspicuous. He was probably enabled, from his residence in the neighbourhood, to direct the miners to proceed with most effect. But the daring valour of Cranage again anticipated these slower operations. He was persuaded to hang a _Buttar_ (a petard) at the castle-gate! Being well animated with sack, he undertook this desperate attempt, crept with the engine from house to house, till he got to that next to the castle, fastened it to the gate, set fire to it, and escaped unhurt! The gate was then burst open, and the garrison, finding it impossible to make any further resistance, surrendered the castle upon promise of quarter for their lives. * * * It is greatly to the honour of the victorious commanders that they restrained their soldiers from pillage, at the expense of a gratuity of £500. One can scarcely err in ascribing this noble and uncommon act of mercy to Colonel Mytton’s solicitude for the welfare of his neighbours. The Earl dispatched intelligence of his success to the Parliament. His letter was read to the House of Commons, on the 27th June, giving an account of his taking the town and castle of Oswaldstree, with 400 prisoners and 300 arms. Thanks were voted to him for this his good service, and former testimonies of affection to the house.” The circumstantial narrative proceeds to state that “his Lordship returned, after this exploit, to his main army at Drayton,” and left Colonel Mytton in defence of the town. The fall of Oswestry was a severe blow to the royal party. Besides opening a door for the reduction of North Wales to the power of the Parliament, it lowered them in the scale of public opinion, a loss, in the declining posture of their affairs, of incalculable importance. Active and energetic as were both Lord Denbigh and Colonel Mytton, in their attack upon Oswestry, still they did not escape the slanders even of their own party. The Earl of Denbigh seems to have felt their calumnies acutely, for a few months after the siege his Lordship wrote a letter to Mytton, vindicating the gallantry of both; which we subjoin:— “COLL. MITTON,
