Ciiillicothe, May 20. PRISONERS OF WAR.| About two hundred and fifty of general'I Uaysbrigade of Kentucky militia have this week passed through Chillicothc—I 1 he forlorn situation of these brave metr awakened the sympathy of our citizens*,u,J-and that liberality which is their characteristic, was not withheld from the poor soldier.These men report, that after they were made prisoners, they were conducted to the ruins of the old British fort Miami, to which they give the appellation of slaughter fien” and there ordered to sit down. The Indians now commenced their barbarities in presence of the British officers. Several ot the officers and men were shot by the Indians who sur-lounded them, while others were selected and dragged out, with tnmaheVks buried in their skulls-—About fortv persons were butchered in this way, when an end was put to savage cruelty, by the interference of Col. Elliott, who it appears had complete controld over Proctor’s allies.—Gai*
