The Prussians had a detached post at Smirzitz. The little garrison there was much harassed by lurking bands of Austrians, who shot their sentries, cut off their supplies, and rendered it almost certain death to any one who ventured to emerge from the ramparts. Some inventive genius among the Prussians constructed a straw man, very like life, representing a sentinel with his shouldered musket. By a series of ropes this effigy was made to move from right to left, as if walking his beat. A well-armed band of Prussians then hid in a thicket near by. Ere long a company of Austrian scouts approached. From a distance they eyed the sentinel, moving to and fro as he guarded his post. A sharp-shooter crept near, and, taking deliberate aim at his supposed victim, fired. A twitch upon the rope caused the image to fall flat. The whole band of Austrians, with a shout, rushed to the spot. The Prussians, from their ambuscade, opened upon them a deadly fire of bullets. Then, as the ground was covered with the mutilated and the dead, the Prussians, causing the welkin to ring with their peals of laughter, rushed with fixed bayonets upon their entrapped foes. Not a single Austrian had escaped being struck by a bullet. Those who were not killed outright were wounded, and were taken captive. This is one of the “slight pleasantries” of war. Frederick’s army was now in a state of great destitution. The region around was so stripped of its resources that it could afford his foragers no more supplies. It was difficult for him to fill his baggage-trains even in Silesia, so much had that country been devastated by war; and wherever any of his supply wagons appeared, swarms of Austrian dragoons hovered around, attacking and destroying them. To add to the embarrassments of the Prussian king, his purse was empty. His subjects could endure no heavier taxation. All the plate which Frederick William had accumulated had been converted into coin and expended. Even the massive silver balustrades, which were reserved until a time of need, were melted and gone. He knew not where to look for a loan. All the nations were involved in ruinous war. All wished to borrow. None but England had money to lend; and England was fighting Frederick, and furnishing supplies for his foes. [Illustration: A SLIGHT PLEASANTRY.] The expenses of the war were enormous. Frederick made a careful estimate, and found that he required at least three hundred and seventy-five thousand dollars a month. He could not carry on another campaign with less than four million five hundred thousand dollars. He had been expecting that Louis XV., who in person was in command of the French army on the Rhine, would send him a re-enforcement of sixty thousand troops to enable him to crush the forces of Prince Charles. But week after week passed, and no re-enforcements came. The French, intent upon their conquest, were as selfishly pursuing their own interests on the Rhine as Frederick was pursuing his in Silesia.
