The contents of the armoury were overhauled and furbished. Seasoned wood was sought throughout the town, for the making of countless arrows; thick porous paper for dressing wounds, according to the standard rules of rough field surgery. The ground within the inner moat was covered over with boards and canvas, to conceal what was done inside; for an investing army is ever full of stratagems for learning the weak points of the besieged. Lofty trees, or high peaks of rock, were sure to be occupied at once, tall towers to be erected on points of vantage. It was even a common thing to fly huge kites, large enough to support a man, and so obtain a bird's-eye view of the interior of an enemy's castle. Sampei organised a band of scouts, and sent them forth to crawl by night along the narrow causeways that intersected the oozy rice fields, bidding them return with earliest information with regard to the coming of the foe. Parties of braves were despatched in all directions to annex the scanty stores which oppression had left to the peasantry. All possible precautions taken, he divided his men into watches, taught each his post and duty, then waited for the future to unroll. Nor had he long to wait. As though rising by magic through the ground, an army of combatants appeared, who surrounded the fortress with their engines. From the top of the central tower, crowned with its copper roof and golden fish, could be descried a host so numerous and well-equipped that Sampei stood marvelling how they could be here so quickly. It soon became manifest that they had no intention of endeavouring to storm the place, at least not yet, for they methodically set about the forming of a line of pallisades, consisting of heavy planks propped by hinged supports, behind which they could safely repose, and starve the foe to extremity.
