This transaction has been the subject of much historical controversy. The enemies of Charles, both in his own and later ages, have considered it as a proof of his indifference at least to the protestant religion, and of his readiness to accept the assistance of Irish rebels on any conditions. His advocates for a long time denied the authenticity of Glamorgan's commissions. But Dr. Birch demonstrated that they were genuine; and, if his dissertation could have left any doubt, later evidence might be adduced in confirmation.[320] Hume, in a very artful and very unfair statement, admitting the authenticity of these instruments, endeavours to show that they were never intended to give Glamorgan any power to treat without Ormond's approbation. But they are worded in the most unconditional manner, without any reference to Ormond. No common reader can think them consistent with the king's story. I do not, however, impute to him any intention of ratifying the terms of Glamorgan's treaty. His want of faith was not to the protestant, but to the catholic. Upon weighing the whole of the evidence, it appears to me that he purposely gave Glamorgan, a sanguine and injudicious man, whom he could easily disown, so ample a commission as might remove the distrust that the Irish were likely to entertain of a negotiation wherein Ormond should be concerned; while by a certain latitude in the style of the instrument, and by his own letters to the lord lieutenant about Glamorgan's errand, he left it open to assert, in case of necessity, that it was never intended to exclude the former's privity and sanction. Charles had unhappily long been in the habit of perverting his natural acuteness to the mean subterfuges of equivocal language.
By these discoveries of the king's insincerity, and by what seemed his infatuated obstinacy in refusing terms of accommodation, both nations became more and more alienated from him; the one hardly restrained from casting him off, the other ready to leave him to his fate.[321]
