The Houses, it must be acknowledged, committed great errors in the conduct of the war, or rather one great error, which brought their affairs into a condition requiring the most perilous expedients. The parliamentary leaders of what may be called the first generation, Essex, Manchester, Northumberland, Hollis, even Pym, all the most eminent men in short, Hampden excepted, were inclined to half measures. They dreaded a decisive victory almost as much as a decisive overthrow. They wished to bring the King into a situation which might render it necessary for him to grant their just and wise demands, but not to subvert the constitution or to change the dynasty. They were afraid of serving the purposes of those fierce and determined enemies of monarchy, who now began to show themselves in the lower ranks of the party. The war was, therefore, conducted in a languid and inefficient manner. A resolute leader might have brought it to a close in a month. At the end of three campaigns, however, the event was still dubious; and that it had not been decidedly unfavourable to the cause of liberty was principally owing to the skill and energy which the more violent roundheads had displayed in subordinate situations. The conduct of Fairfax and Cromwell at Marston had, exhibited a remarkable contrast to that of Essex at Edgehill, and to that of Waller at Lansdowne.
If there be any truth established by the universal experience of nations, it is this; that to carry the spirit of peace into war is weak and cruel policy. The time for negotiation is the time for deliberation and delay. But when an extreme case calls for that remedy which is in its own nature most violent, and which, in such cases, is a remedy only because it is violent, it is idle to think of mitigating and diluting. Languid war can do nothing which negotiation or submission will not do better: and to act on any other principle is, not to save blood and money, but to squander them.
