They then procured a quantity of combustible matter, set fire to it, and approached under covert of the darkness, so near the palisades as to throw the burning materials into the fort. But the inmates had availed themselves of the two days' consultation, granted them by the treacherous foe, to procure an ample supply of water; and they had the means of extinguishing the burning faggots as they fell. Finding their efforts to fire the fort ineffectual, they returned again to their arms, and continued to fire upon the station for some days. Taught a lesson of prudence, however, by what had already befallen them, they kept at such a cautious distance, as that their fire took little effect. A project to gain the place, more wisely conceived, and promising better success, was happily discovered by Colonel Boone. The walls of the fort were distant sixty yards from the Kentucky river. The bosom of the current was easily discernible by the people within. Boone discovered in the morning that the stream near the shore was extremely turbid. He immediately divined the cause. The Indians had commenced a trench at the water level of the river bank, mining upwards towards the station, and intending to reach the interior by a passage under the wall. He took measures to render their project ineffectual, by ordering a trench to be cut inside the fort, across the line of their subterraneous passage. They were probably apprised of the countermine that was digging within, by the quantity of earth thrown over the wall. But, stimulated by the encouragement of their French engineer, they continued to advance their mine towards the wall, until, from the friability of the soil through which it passed, it fell in, and all their labor was lost. With a perseverance that in a good cause would have done them honor, in no wise discouraged by this failure to intermit their exertions, they returned again to their fire arms, and kept up a furious and incessant firing for some days, but producing no more impression upon the station than before. During the siege, which lasted eight days, they proposed frequent parleys, requesting the surrender of the place, and professing to treat the garrison with the utmost kindness. They were answered, that they must deem the garrison to be still more brutally fools than themselves, to expect that they would place any confidence in the proposals of wretches who had already manifested such base and stupid treachery. They were bidden to fire on, for that their waste of powder and lead gave the garrison little uneasiness, and were assured that they could not hope the surrender of the place, while there was a man left within it. On the morning of the ninth day from the commencement of the siege, after having, as usual, wreaked their disappointed fury upon the cattle and swine, they decamped, and commenced a retreat.
