Let Rumbold’s declaration, then, be examined upon these principles, and we shall find that it has every character of truth, without a single circumstance to discredit it. He was so far from entertaining any hope of pardon, that he did not seem even to wish it; and indeed if he had had any such chimerical object in view, he must have known that to have supplied the government with a proof of the Rye House assassination plot, would be a more likely road at least, than a steady denial, to obtain it. He left none behind him for whom to entreat favour, or whose welfare or honour was at all affected by any confession or declaration he might make. If, in a prospective view, he was without temptation, so neither, if he looked back, was he fettered by any former declaration; so that he could not be influenced by that erroneous notion of consistency to which it may be feared that truth, even in the most awful moments, has in some cases been sacrificed. His timely escape in 1683 had saved him from the necessity of making any protestation upon the subject of his innocence at that time; and the words of the letter to Walcot are so far from containing such a protestation, that they are quoted (very absurdly, it is true) by Sir John Dalrymple as an avowal of guilt. If his testimony is free from these particular objections, much less is it impeached by his general character, which was that of a bold and daring man, who was very unlikely to feel shame in avowing what he had not been ashamed to commit, and who seems to have taken a delight in speaking bold truths, or at least what appeared to him to be such, without regarding the manner in which his hearers were likely to receive them. With respect to the last consideration, that of the opposite evidence, it all depends upon the veracity of men who, according to their own account, betrayed their comrades, and were actuated by the hope either of pardon or reward.
It appears to be of the more consequence to clear up this matter, because if we should be of opinion, as I think we all must be, that the story of the intended assassination of the king, in his way from Newmarket, is as fabulous as that of the silver bullets by which he was to have been shot at Windsor, a most singular train of reflections will force itself upon our minds, as well in regard to the character of the times, as to the means by which the two causes gained successively the advantage over each other. The Royalists had found it impossible to discredit the fiction, gross as it was, of the popish plot; nor could they prevent it from being a powerful engine in the hands of the Whigs, who, during the alarm raised by it, gained an irresistible superiority in the House of Commons, in the City of London, and in most parts of the kingdom. But they who could not quiet a false alarm raised by their adversaries, found little or no difficulty in raising one equally false in their own favour, by the supposed detection of the intended assassination.
