On the morning of 17 August, Cromwell attacked Langdales troops, strongly deployed on Ribbleton Moor to guard the road into Preston. The Royalists held off the Parliamentarians for several hours but were finally routed and driven back into Preston where the survivors were taken prisoner.
On 18 August, Cromwell advanced south with his main force in pursuit of the disordered Scots. On 19 August, the Scots made a last stand in a strong defensive position at Winwick near Warrington but were driven back by Cromwell after several hours fierce fighting.
With the destruction of the Engager army, the second Civil War was effectively over. Colchester surrendered to Fairfax on 28 August, other Royalist outposts in the south soon followed suit. Lord Byron fled from north Wales to the Isle of Man. Sir Philip Musgrave and the northern Royalists surrendered Carlisle in October. Only Pontefract Castle held out for the King in a stubborn and futile resistance that lasted until March 1649. Cromwell marched into Scotland on 21 September. He struck a wary accord with the Marquis of Argyll and obtained the removal from office of everyone who had supported the Engagement.
The tide of the Civil War culminating in the defeat at the Battle of Preston of Charles army in August 1648 by Parliamentary forces under the command of Oliver Cromwell. The King was charged with high treason against the realm of England. At his trial, Charles refuted the legitimacy of the court and refused to enter a plea. Not withstanding the absence of a plea, the court rendered a verdict of guilty and a sentence of death declaring:
That the king, for the crimes contained in the charge, should be carried back to the place from whence he came, and thence to the place of execution, where his head should be severed from his body.
Three days later, the king was led to the scaffold erected at Whitehall, London.
