From 1642 to 1646, the First Civil War was waged. This was a war between the king and the Parliament over taxation, militia, and religion. The south-east, and London especially, were for Parliament; the wilder parts, especially Wales, were for the king. The only important part of Wales that declared for Parliament was the southern part of Pembrokeshire, which had been English ever since the reign of Henry II. Wales was important to the king for two reasons. For one thing, it could give him an army, and he came, time after time, to get a new one. When he unfurled his flag and began the war at Nottingham in 1642, he came to Shrewsbury, and there five thousand Welshmen joined him. With these and others he marched against London, fighting the battle of Edgehill on the way. While the king made many attempts to get London until 1644, and while the New Model army attacked him between 1645 and 1647, the Welsh fought in nearly all his battles, their infantry suffering heavily in the two greatest battles, Marston Moor and Naseby. The war went on in Wales itself also—Rupert and Gerard being the chief Royalist leaders, and Middleton and Michael Jones being the chief Parliamentary ones. No great battles were fought, but there were several skirmishes, and much taking and retaking of castles and towns. Wales was important to the king, also, because it commanded the two ways to Ireland. The King thought, almost to the last, that an Irish army would save him. Welsh garrisons held the two ports for Ireland, Chester and Bristol. Bristol was stormed by a great midnight assault, and Chester was forced to yield. In March 1647 Harlech yielded, and the war came to an end. By that time the king was a prisoner in the hands of the army.
