The increase of the information received by the Government left its trace on Salisbury's correspondence. Whether the letter to Parry, from which a quotation has already been given, was sent away on the 6th, is unknown; but it was copied and completed, with sundry alterations, for Cornwallis and Edmondes, the ambassadors at Madrid and Brussels, and signed by Salisbury on the 7th, though it was kept back and sent off with two postscripts on the 9th, and it is likely enough that the letter to Parry was treated in the same way. One of the alterations concerns Fawkes's admission that he had taken the Sacrament as well as an oath to keep the secret. What is of greater significance is, that there is absolutely no mention of a mine in the letter. If it had really been written on the 9th, this silence would have gone far to justify Father Gerard's suspicions, as the existence of the mine was certainly known to the Government at that date. On the 7th the Government knew nothing of it.[38] That Fawkes had already been threatened with torture is known,[39] and it may easily be imagined that the threats had been redoubled after this last unsatisfactory acknowledgment. On the morning of the 8th, however, Waad, who was employed to worm out his secrets, reported that little was to be expected. "I find this fellow," he wrote, "who this day is in a most stubborn and perverse humour, as dogged as if he were possessed. Yesternight I had persuaded him to set down a clear narration of all his wicked plots from the first entering to the same, to the end they pretended, with the discourses and projects that were thought upon amongst them, which he undertook [to do] and craved time this night to bethink him the better; but this morning he hath changed his mind and is [so] sullen and obstinate as there is no dealing with him."[40] The sight of the examiners, together with the sight of the rack,[41] changed Fawkes's mind to some extent. He was resolved that nothing but actual torture should wring from him the names of his fellow plotters, who so far as was known in London were still at large.[42] He prepared himself, however, to reveal the secrets of the plot so far as was consistent with the concealment of the names of those concerned in it. His fifth examination on the 8th, the last before the one taken under torture on the 9th, gives to the inquirer into the reality of the plot all that he wants to know.
