On the very day of Richard's accession the officers began to conspire against their new master. The good understanding which existed between him and his Parliament hastened the crisis. Alarm and resentment spread through the camp. Both the religious and the professional feelings of the army were deeply wounded. It seemed that the Independents were to be subjected to the Presbyterians, and that the men of the sword were to be subjected to the men of the gown. A coalition was formed between the military malecontents and the republican minority of the House of Commons. It may well be doubted whether Richard could have triumphed over that coalition, even if he had inherited his father's clear judgment and iron courage. It is certain that simplicity and meekness like his were not the qualities which the conjuncture required. He fell ingloriously, and without a struggle. He was used by the army as an instrument for the purpose of dissolving the Parliament, and was then contemptuously thrown aside. The officers gratified their republican allies by declaring that the expulsion of the Rump had been illegal, and by inviting that assembly to resume its functions. The old Speaker and a quorum of the old members came together, and were proclaimed, amidst the scarcely stifled derision and execration of the whole nation, the supreme power in the commonwealth. It was at the same time expressly declared that there should be no first magistrate, and no House of Lords.
But this state of things could not last. On the day on which the long Parliament revived, revived also its old quarrel with the army. Again the Rump forgot that it owed its existence to the pleasure of the soldiers, and began to treat them as subjects. Again the doors of the House of Commons were closed by military violence; and a provisional government, named by the officers, assumed the direction of affairs.
Meanwhile the sense of great evils, and the strong apprehension of still greater evils close at hand, had at length produced an alliance between the Cavaliers and the Presbyterians. Some Presbyterians had, indeed, been disposed to such an alliance even before the death of Charles the First: but it was not till after the fall of Richard Cromwell that the whole party became eager for the restoration of the royal house. There was no longer any reasonable hope that the old constitution could be reestablished under a new dynasty. One choice only was left, the Stuarts or the army. The banished family had committed great faults; but it had dearly expiated those faults, and had undergone a long, and, it might be hoped, a salutary training in the school of adversity. It was probable that Charles the Second would take warning by the fate of Charles the First. But, be this as it might, the dangers which threatened the country were such that, in order to avert them, some opinions might well be compromised, and some risks might well be incurred. It seemed but too likely that England would fall under the most odious and degrading of all kinds of government, under a government uniting all the evils of despotism to all the evils of anarchy. Anything was preferable to the yoke of a succession of incapable and inglorious tyrants, raised to power, like the Deys of Barbary, by military revolutions recurring at short intervals. Lambert seemed likely to be the first of these rulers; but within a year Lambert might give place to Desborough, and Desborough to Harrison. As often as the truncheon was transferred from one feeble hand to another, the nation would be pillaged for the purpose of bestowing a fresh donative on the troops. If the Presbyterians obstinately stood aloof from the Royalists, the state was lost; and men might well doubt whether, by the combined exertions of Presbyterians and Royalists, it could be saved. For the dread of that invincible army was on all the inhabitants of the island; and the Cavaliers, taught by a hundred disastrous fields how little numbers can effect against discipline, were even more completely cowed than the Roundheads.
