Geoffrey then stated how he and his brother, being at the upper window of the warehouse, had on two days in succession seen a crossbow discharged from a neighbouring window, and had noticed a Spanish soldier come out of a battery and pick up something which they believed to be the bolt, and how he and his brother had reported the circumstances to Captain Vere. That officer then took up the story, and stated that seeing the evidence was not conclusive, and it was probable that if an attempt was made to arrest the person, whomsoever he might be, who had used the crossbow, any evidence of treasonable design might be destroyed before he was seized, he had accepted the offer of Master Vickars to climb the roof, lower himself to the window from which the bolt would be shot, and, if possible, strike it from the man's hands, so that it would fall down the roof to the courtyard below, where men were placed to seize it. Geoffrey then related how he, with the two soldiers guarding the prisoner, had scaled the roof and taken a position by the window; how he had seen the crossbow thrust out, and had struck it from the hands of the man holding it; how the latter had leaned out, and would have shot him had not Roger Browne from his post above the window shot him in the shoulder. "Here are the crossbow and pistol," Captain Vere said; "and this is the bolt as it was picked up by my men. You see, sir, there is a paper fastened round it. I know not its contents, for I judged it best to leave it as it was found until I placed it in your hands." The governor cut the string, unrolled the paper and examined it. It contained a statement as to the state of the wall, with remarks where it was yielding, and where the enemy had best shoot against it. It said that the defenders had in the night begun to form a half moon behind it, and contained a sketch showing the exact position of the new work. "Gentlemen, what think you of this?" the governor asked the English officers. "There can be no doubt that it is a foul act of treachery," Williams said, "and the traitor merits death." "We will not decide upon it ourselves," the governor said. "I will summon six of the leading citizens, who shall sit as a jury with us. This is a grave matter, and touches the honour of the citizens as well as the safety of the town." In a few minutes the six citizens summoned arrived. The evidence was again given, and then the prisoner was asked what he had to say in his defence. "It is useless for me to deny it," he replied. "I am caught in the act, and must suffer for it. I have done my duty to the King of Spain, my sovereign; and I warn you he will take vengeance for my blood."
