Paul's ears tingled as he listened. Notwithstanding the peril in which he stood, his heart beat with joy. The words of Mr. Moncrief came back to him: "You have not only done a great service for me and my brother, Paul, but for your country." He had almost forgotten those words in the whirl of events that had since happened at Garside, but now they came flashing back, shining out vividly as a beacon in the darkness around him.
"No; we must not make another," answered Brockman, sending his fist vigorously into the palm of his hand to emphasize his words. There was silence between the two for a moment, then it was again broken by Zuker.
"Those ancestors of yours were dull dogs, Brockman, but there must have been some grit in them to have got up to Chatham. See, they got to this point." Paul could see that a chart was spread out upon the table, and that Zuker was pointing with his finger to a place on it. "Here is the River Medway, which, as you know, can be reached through this tunnel."
The river through that tunnel! Was he awake or dreaming? Paul could scarcely believe the evidence of his ears. His heart thumped so loudly against his ribs that he feared the conspirators might hear him.
"A chain had been drawn across the river, for all England was in a state of alarm at the approach of the Dutchmen," went on Zuker. "Fortifications had been added to Sheerness and Upnor Castle just here."
Brockman bent over the chart and followed the finger of Zuker.
"Just there. And the chain—what happened to the chain?"
"Sheerness was first taken, and then, taking advantage of a spring tide and an easterly wind, the Dutch broke the chain."
"Broke it? But wasn't it fortified?"
"It was guarded by three ships, but the Dutch took them. They played havoc with several other vessels, and advanced with six men-o'-war and five fireships as far as Upnor Castle, where they burned three more. That was good, wasn't it?"
