The militia of the city were absent at the seat of war, fighting the battles of the nation against treason and secession, and there was no adequate force in the city for the first twelve hours to resist at all points the vast and infuriated mob. The police force was not strong enough in any precinct to make head, unaided, against the overwhelming force. No course was left but to concentrate the whole force at the Central Department, and thence send detachments able to encounter and conquer the rioters. This course was promptly adopted on Monday morning. The military were called upon to act in aid of the civil force to subdue the treasonable mob, protect life and property, and restore public order. Under such, adverse circumstances you were called upon to encounter a mob of such strength as have never before been seen, in this country. The force of militia under General Sandford, who were called into service by the authority of this Board, were concentrated by him at and held the arsenal in Seventh Avenue, throughout the contest. The military forces in command of Brevet Brigadier-general Harvey Brown reported at the Central Department, and there General Brown established his head-quarters, and from there expeditions, combined of police and military force, were sent out that in all cases conquered, defeated, or dispersed the mob force, and subjected them to severe chastisement. In no instance did these detachments from the Central Department, whether of police alone or police and military combined, meet with defeat or serious check. In all cases they achieved prompt and decisive victories. The contest continued through Monday, Tuesday, Wednesday, Thursday, and till 11 o'clock on Thursday night, like a continuous battle, when it ended by a total and sanguinary rout of the insurgents. During the whole of those anxious days and nights, Brigadier-general Brown remained at the Central Department, ordering the movements of the military in carefully considered combinations with the police force, and throughout the struggle, and until its close, commanded the admiration and gratitude of the Police Department and all who witnessed his firm intelligence and soldierly conduct. It is understood that he had at no time under his immediate command more than three hundred troops, but they were of the highest order, and were commanded by officers of courage and ability. They cordially acted with, supported, and were supported by, the police, and victory in every contest against fearful odds, was the result of brave fighting and intelligent command. In the judgment of this Board, the escape of the city from the power of an infuriated mob is due to the aid furnished the police by Brigadier-general Brown and the small military force under his command. No one can doubt, who saw him, as we did, that during those anxious and eventful days and nights Brigadier-general Harvey Brown was equal to the situation, and was the right man in the right place.
