The coming recrudescence of civil war differed somewhat, therefore, in its origin from that between the rival houses of York and Lancaster. In these, political rancour was fostered by great nobles, and armies were formed on the feudalistic principle of personal servitude to these chiefs; while on the other side was the trading spirit openly fostered by Edward the Fourth. The Stuart wars are much more personal and individual throughout. The men, the rank and file even, fought with interest in the cause, and—as a rule, not as an exception, as before—joined either side from feelings of personal predilection. Hence it was that when the Restoration came, there was less bitter antagonism between the factions than when Warwick fell at Barnet. Then the king or queen or the feudal lord decided the measure of slaughter. In the Stuart wars no such order as that of Edward, before Barnet, “to give no quarter,” would have been, save in the most exceptional case, obeyed. It was only when the purely theological animosity was paramount that needless cruelties followed victory. The Covenanters at Bothwell Brig were personally hateful to men like Claverhouse, for religious as well as other reasons; so also the massacres at Drogheda, of which more anon. Stern repression of the severest kind in such cases was both the law and custom in those days.

The actual outbreak of hostilities was preceded by minor outbreaks, which increased the growing antagonism. Ships were lent to France and used against the Huguenots of Rochelle, and the failure of an attempt at Cadiz increased the irritation; and when the troops returned from the Continent, they were not disbanded, as was customary, but billeted on the population, and martial law was introduced during a time of peace. Lastly, the efforts of the Star Chamber to raise fresh loans accorded but little with the English spirit, and the direct tax of ship-money on inland as well as coastal towns, together with the attempted arrest of the five members of the House of Commons hostile to the king’s policy, brought matters to a climax.

Thus the Civil War began, much as in former times, without real strategy. At first, certainly, there was little or no plan of campaign. When an army formed, it moved on some point that seemed locally of value, or to some town or garrison that wanted help. The only broad principle of a very feeble strategy seems to have been to threaten (or protect) London, and on the Parliament side to keep free for use the road from London to the West.

Practically, as in the Wars of the Roses, the political situation was this. The north part of the Midlands and the west favoured the Royalists, the east and south the Parliamentarians. But in both cases there were numerous centres of disaffection in each area, and the commercial spirit of the great towns and seaports in the south and east was hostile to the king.

Speaking generally, too, the nobles and gentry favoured the royal cause, the middle classes that of the Parliament; though of course there were many exceptions on both sides. The fashionable, worldly, and gay were with Charles, the serious-minded, austere, and visionary with the Parliament. But there was more than this: even the “people” found a recruiting ground, for London trained bands and peaceful traders donned buff and bandolier to fight in the national cause. As at Barnet, though now much more so, the commercial class stood side by side with that which deemed itself, by birth and education, more military.

The gradual introduction of the supply train had introduced the elements of strategy, though the study was still in its infancy. The strategical objectives were rather more distinct, but even now there is little trace of a connected serious strategic plan. The isolated armies did not yet unite to a definite strategic end; the plan of campaign was much the same as before, though a little less so. The king assembled an army at X, the Parliament formed one at Y to beat it. The main difference is, that in the Wars of the Roses defeat generally meant dispersion, in this Civil War it meant more or less retreat to re-form. The art of war was growing up, that was all.

Briefly speaking, the only noteworthy points of military interest are these which follow; as the most instructive tactical example is that of the battle of Naseby.

The early campaigns merely tell the usual tale of disconnected skirmishes and resultless battles. Nominally the Parliament guarded the capital, their opponents wanted to seize it. But they rarely tried, and never seriously. In 1643, when Essex was retreating from the relief of Gloucester, he was intercepted by the king at Newbury, where strategically and tactically the royal forces were skilfully posted. But the battle partakes of the nature of chance rather than intent. Nothing practically came of it; but it showed the Cavaliers that if infantry stood firm, the most reckless gallantry of cavalry could do nothing.

In that same year two political steps were taken that led eventually to serious results. The Parliament allied itself with Scotland, and increased Cromwell’s innate dislike to that nation; on the other hand, Charles, to all intents and purposes, allied himself temporarily with the Irish, and raised the theological hatred of his British foes to fever heat. But constant war was hardening and teaching Cromwell and his men, if it taught their opponents nothing. The handling of the three armies in 1644 was skilful. Throughout the whole contest, too, the better and steadier pay of the Parliamentary army told; they plundered less than their harder-up adversaries, and as the rank and file improved, so did their leaders, when the “self-denying ordinance” eliminated incompetent soldiers, and handed over the conduct of the war to those who meant to bring it to a successful issue. The true professional soldier was being made. The superior and more intelligent strategy of the end of the campaign of 1646 clearly shows this, and by the end of the following year hostilities had practically ceased.
