As the various columns moved through the streets, from the lower to the upper part of the City, the occasional low but distinct word of command, and the steady tramp of armed men, attracted attention, and windows and doorways and sidewalks became filled with silent, wondering awestruck spectators. From street, lane and alley, they thronged the thoroughfares in which the troops were moving, and keeping pace with them, in like silence, moved steadily on. By exactly calculated movements, each division came upon the ground almost at the precise spot it was to occupy, and upon deploying into line formed part of a hollow square enclosing the whole space in which the Prison was situated. A field piece heavily loaded with grape, was placed in position in front of the iron gate of the Prison. A body of riflemen marched down Broadway, cleared and took possession of a house next the Prison, and which commanded its roof, and filled the roof of the house with sharpshooters. Another body of riflemen were posted on a bluff in rear of the Jail, and which commanded that side. In the meantime windows, roofs of houses, and hill tops at a safe distance were crowded with spectators. Such sounds as must necessarily attend the moving and getting into position so large a body of men were soon hushed; and in profound silence, all awaited the progress of events.

The Sheriff informed Casey that the Prison was surrounded by two thousand armed men and that he had no force adequate to his protection. Casey finally concluded to go with the Committee provided two respectable citizens would assure him that he should have a fair trial, and not be dragged through the streets. A pledge to that effect was given him by the President and other members of the Executive Committee. The Committee then withdrew from the Prison, and, with their armed escort, awaited the surrender of the prisoner. City Marshal North having placed irons upon him, led him to the door of the Prison and delivered him into the hands of the Committee. He was then placed in a close carriage, Mr. North, at Casey's request, taking a seat by his side, and two members of the Executive Committee also
