This commission could be only intended to lie ready, till the time should require it. To have attempted to raise any forces, would have been certain destruction; it could be of use only when the forces should appear. This was, however, an act preparatory to martial hostility. Crispe would, undoubtedly, have put an end to the session of parliament, had his strength been equal to his zeal: and out of the design of Crispe, which involved very little danger, and that of Waller, which was an act purely civil, they compounded a horrid and dreadful plot.
The discovery of Waller's design is variously related. In Clarendon's History, it is told, that a servant of Tomkyns, lurking behind the hangings, when his master was in conference with Waller, heard enough to qualify him for an informer, and carried his intelligence to Pym. A manuscript, quoted in the Life of Waller, relates, that "he was betrayed by his sister Price, and her presbyterian chaplain, Mr. Goode, who stole some of his papers; and, if he had not strangely dreamed the night before, that his sister had betrayed him, and, thereupon, burnt the rest of his papers, by the fire that was in his chimney, he had certainly lost his life by it." The question cannot be decided. It is not unreasonable to believe, that the men in power, receiving intelligence from the sister, would employ the servant of Tomkyns to listen at the conference, that they might avoid an act so offensive as that of destroying the brother by the sister's testimony.
The plot was published in the most terrifick manner. On the 31st of May, 1643, at a solemn fast, when they were listening to the sermon, a messenger entered the church, and communicated his errand to Pym, who whispered it to others that were placed near him, and then went with them out of the church, leaving the rest in solicitude and amazement. They immediately sent guards to proper places, and, that night, apprehended Tomkyns and Waller; having yet traced nothing but that letters had been intercepted, from which it appeared that the parliament and the city were soon to be delivered into the hands of the cavaliers.
They, perhaps, yet knew little themselves, beyond some general and indistinct notices. "But Waller," says Clarendon, "was so confounded with fear, that he confessed whatever he had heard, said, thought, or seen; all that he knew of himself, and all that he suspected of others, without concealing any person of what degree or quality soever, or any discourse which he had ever upon any occasion entertained with them; what such and such ladies of great honour, to whom, upon the credit of his wit and great reputation, he had been admitted, had spoke to him in their chambers upon the proceedings in the houses, and how they had encouraged him to oppose them; what correspondence and intercourse they had with some ministers of state at Oxford, and how they had conveyed all intelligence thither." He accused the earl of Portland, and lord Conway, as cooperating in the transaction; and testified, that the earl of Northumberland had declared himself disposed in favour of any attempt, that might check the violence of the parliament, and reconcile them to the king.
He, undoubtedly, confessed much which they could never have discovered, and, perhaps, somewhat which they would wish to have been suppressed; for it is inconvenient, in the conflict of factions, to have that disaffection known which cannot safely be punished.
Tomkyns was seized on the same night with Waller, and appears, likewise, to have partaken of his cowardice; for he gave notice of Crispe's commission of array, of which Clarendon never knew how it was discovered. Tomkyns had been sent with the token appointed, to demand it from lady Aubigney, and had buried it in his garden, where, by his direction, it was dug up; and thus the rebels obtained, what Clarendon confesses them to have had, the original copy.
It can raise no wonder that they formed one plot out of these two designs, however remote from each other, when they saw the same agent employed in both, and found the commission of array in the hands of him, who was employed in collecting the opinions and affections of the people.
Of the plot, thus combined, they took care to make the most. They sent Pym among the citizens, to tell them of their imminent danger, and happy escape; and inform them, that the design was, "to seize the lord mayor, and all the committee of militia, and would not spare one of them." They drew up a vow and covenant, to be taken by every member of either house, by which he declared his detestation of all conspiracies against the parliament, and his resolution to detect and oppose them. They then appointed a day of thanksgiving for this wonderful delivery; which shut out, says Clarendon, all doubts whether there had been such a deliverance, and whether the plot was real or fictitious.
On June 11, the earl of Portland and lord Conway were committed, one to the custody of the mayor, and the other of the sheriff; but their lands and goods were not seized.
Waller was still to immerse himself deeper in ignominy. The earl of Portland and lord Conway denied the charge; and there was no evidence against them but the confession of Waller, of which, undoubtedly, many would be inclined to question the veracity. With these doubts he was so much terrified, that he endeavoured to persuade Portland to a declaration like his own, by a letter extant in Fenton's edition. "But for me," says he, "you had never known any thing of this business, which was prepared for another; and, therefore, I cannot imagine why you should hide it so far as to contract your own ruin by concealing it, and persisting unreasonably to hide that truth, which without you already is, and will every day be made more manifest. Can you imagine yourself bound in honour to keep that secret, which is already revealed by another? or possible it should still be a secret, which is known to one of the other sex? If you persist to be cruel to yourself, for their sakes who deserve it not, it will, nevertheless, be made appear, ere long, I fear, to your ruin. Surely, if I had the happiness to wait on you, I could move you to compassionate both yourself and me, who, desperate as my case is, am desirous to die with the honour of being known to have declared the truth. You have no reason to contend to hide what is already revealed—inconsiderately to throw away yourself, for the interest of others, to whom you are less obliged than you are aware of."
