The conspirators were to be scattered about Turnham Green in taverns and ale-houses, and to be brought together upon a signal being given. Each body of them was under a leader, so as to give the proceeding the air of a military act. While some were to attack the king's guards, others had been especially selected to shoot at the king himself. James had sent over a number of his own body-guard to be in readiness to support the conspirators. It appears, however, that the military men engaged in the work were very unwilling to undertake it, unless they received a commission from James himself. This document was therefore drawn up and signed by the king, and on seeing it, some of them imagined that the undertaking in which they engaged, although of a somewhat desperate character, was as honourable as that of entering into a campaign in regular service. Some, however, felt great doubts about the matter, as they could not help viewing it in its true light. Among these were two captains, Pendergrast, an Irish officer, and Fisher, an Englishman, and a Frenchman named De la Rue, who without any agreement with each other, at different times gave information to the Earl of Portland of the contemplated assassination of the king. William at first was very unwilling to believe in the plot, and it was not without difficulty that the Earl of Portland could persuade his Majesty not to go forth on his hunting expedition on that eventful 15th day of February. The greater number of the conspirators not having received such early information as did Sir George Barclay, continued to meet, even on that very day, hoping still to carry out their plan on the following Saturday. They were nearly all seized, most of them in their beds, before they had received any notice of the discovery of the plot. Charnock, who had been a Fellow of Magdalen College, Oxford, and had become its Popish vice-president, was an indefatigable agent of the Jacobites. So completely imbued had he become with Jesuitical principles, that he had persuaded himself that he had full right to murder the king, having as he supposed a commission from the person he considered the legal proprietor of the throne. He offered to disclose all he knew of the consultations and designs of the Jacobites, if his life were spared, and the reply of King William is worthy of note: "I desire not to know them," feeling assured probably, that many were in it whom he hoped still to win over by generosity and kindness. Sir John Friend and Sir William Parkyns were next tried, and were executed, on being found guilty, at Tyburn, on which occasion three of the non-juring clergy attended them, and had the audacity at the place of execution to give them public absolution, with an imposition of hands in the view of all people, for the act in which they had been engaged.
