"A quick victory offered Charles the best chance of winning the war. In the autumn of 1642 he had an opportunity to do so but failed for reasons that were not primarily due to deficiencies in supply. There certainly were shortcomings in this area but Parliament had its own problems too. The longer the war went on, the more likely it became that Parliament, with its commercial and economic superiority, would win. The royalists did make good use of the facilities at their disposal and focused their efforts on the production of war matériel. They exploited their natural resources, developed existing industries, and founded new ones where necessary. However, their workshops, mills, and furnaces could not produce enough goods to meet the demands of their armies, forcing the king to reply increasingly upon imports."
