The Civil War

       King Charles I
King Charles The Civil War started on 22 August 1642, when Charles I raised his standard at Nottingham. North Wales was, as a whole, regarded as Royalist territory and the nobility and gentry, with few exceptions like the majority of the Welsh counties, declared for the King. Though the part North Wales played in the conflict was not greatly conspicuous, it was of considerable local interest and consequence. When Charles was mustering his forces in York in that year, he received an address from the gentry, ministers and freeholders of the county of Flint full of intense and fervid expressions of loyalty and allegiance. The county also paid an assessment of £750 towards the support of the Royalist Army.

Colonel Roger Mostyn of Mostyn Hall, then just aged twenty-two years, was one of the first of the local gentry to take up arms for the cause of the king. Within a fortnight, under His Majesty's Commission, he raised a rough and ready force, 1,500 strong, mostly comprised of agricultural workers, miners and labourers, which he equipped and maintained at his own expense. Also at his own cost, he repaired the timeworn and neglected Flint Castle, putting it in a defensible state and garrisoned with a strong and well-armed military. It was to serve as a useful base for harrying the besiegers of Chester and for helping blockade runners to get into the city by water. With Mostyn in the castle was his uncle, John Mostyn, who was a Member of Parliament for Flintshire until he was dismissed from the House on 5 February 1643 for his allegiance to the King.

Oliver Cromwell In 1643 a formidable Parliamentary Army of 2,000 men under Sir Thomas Middleton and Sir William Brereton took Hawarden Castle and proceeded to Flint and besieged the castle. Two days after the siege began, forty-six of Mostyn's cavalrymen broke away from the castle and either surrendered to the enemy or returned to their own homes. The gallant defenders defiantly withstood the siege until all their provisions, including their horses were consumed when they were allowed to march out with full military honours and to return to their homes and occupations and instructed to make a declaration of peace with the new authorities within six months. Both the town, which was then little more than a rural village, and the castle suffered a heavy bombardment by the Parliamentary batteries and the castle was also assailed by ships of war from the River Dee. Fierce and bloody fighting raged in the streets and the town left stunned and shattered. The county, like the whole of the country, soon faced the horrors of war, with raids for sheep and cattle carried out by both sides to feed the hungry troops and records show that fire-raising, murder and pillage sometimes marked the trail of the contending armies. All able-bodied men between sixteen and sixty were liable for military service in the war-wracked country.

One winter, when Sir Thomas Middleton held the castle he retired when about 2,000 Irish Royalists bedraggled and in a sorry plight were landed at Mostyn docks and the castle was temporarily abandoned. Flint Castle was retaken by the Royalists under the command of Sir William Vaughan in September 1645 where they were joined by the garrison from Beeston Castle after its capitulation but the castle was surrended to General Mitton on 29 August 1646.

When after a terrible siege the city was taken by the Parliamentary Forces, Mostyn escaped and crossed to Dublin, where he managed to recruit another contingent of fighting-men for the Royalists. In 1658 he was captured and imprisoned for a brief time in Conway Castle. He was later released upon his own parole, 'To be in his own House at Mostyn and to do nothing prejudicial to the present Government'. Like any Royalists, he suffered severely for his loyalty and had spent over £60,000 of his personal fortune in the campaign. Many of the family treasures from Mostyn Hall were sold and for several years he lived quietly at Plas Ucha, a large farmhouse on the estate. The gentry among the North Wales Royalists were heavily fined by the new Parliament for their support of Charles I. Roger Mostyn, described as 'The Governor, Flint Castle' was fined £825 and his neighbour Robert Pennant fined £40.6.8. 'For taking up arms for the King'. However, with their great resources of land and properties and commercial interests, the family fortune was eventually regained and after the Restoration, the valiant Colonel Roger Mostyn was rewarded by Charles II in 1660 when he was created a baronet for his services.

For a time the castle was garrisoned for Parliament with one tower used as a prison. On 22 December 1646 Parliament voted that Flint Castle should be dismantled and soon the stubborn old walls shuddered and fell in a thunder of gunpowder.  In 1647, the garrison was removed, and along with other North Wales castles, it was slighted as ordered. Exactly what demolition was then undertaken is not clear, but debris of this date was found during archaeological excavations of the ditch near the south-west tower. In 1652, Flint was described as almost buried in its own ruins.
The town had suffered grievously in the bitter misfortunes of the hostilities. The Parish Church had been spoiled and desecrated and the streets were silent and seemingly deserted. The Civil War did not finally end until 1651. A traveller in Flint a few years later wrote, 'They have no saddler, taylor, weaver, baker, butcher, brewer or button-maker. They have not so much as the signe of an ale-house, so that I was doubtful of a lodging'. But life gradually returned and it seemed that phoenix-like the old town rose again from the destruction of nine grim and ruinous years of strife. For after the Restoration, the people of Flint petitioned Charles 11 and complained that as a reprisal for their loyalty to his father Charles I, the Assizes had been taken away from the town by Oliver Cromwell and they beseeched for them to be restored. Their petition was granted and subsequently the Great Sessions again met in Flint on their Circuit.
