The statement of the Police Commissioners, Acton and Bergen, on this point is conclusive. They say that General Sandford's error consisted in "not choosing to be in close communication with this department, when alone through the police telegraph, and other certain means, trustworthy information of the movements of the mob could be promptly had." That single statement is enough to overthrow all of General Sandford's assertions about the riot. It was hardly necessary for them to declare further in their letter to General Brown: "So far from your action having had the effect supposed by General Sandford, we are of the opinion, already expressed in our address to the police force, that through your prompt, vigorous, and intelligent action, the intrepidity and steady valor of the small military force under you, acting with the police force, the riotous proceedings were arrested on Thursday night, and that without such aid mob violence would have continued much longer." WELL-EARNED PRAISE. On the week after the riot the Board of Police Commissioners issued the following address to the force, in which a well-earned tribute is paid to the military: _To the Metropolitan Police Force._ On the morning of Monday, the 13th inst., the peace and good order of the city were broken by a mob collected in several quarters of the city, for the avowed purpose of resisting the process of drafting names to recruit the armies of the Union. Vast crowds of men collected and fired the offices where drafting was in progress, beating and driving the officers from duty. From the beginning, these violent proceedings were accompanied by arson, robbery, and murder. Private property, unofficial persons of all ages, sexes, and conditions, were indiscriminately assailed--none were spared, except those who were supposed by the mob to sympathize with their proceedings. Early in the day the Superintendent was assaulted, cruelly beaten, robbed, and disabled by the mob which was engaged in burning the provost marshal's office in Third Avenue, thus in a manner disarranging the organization at the Central Department, throwing new, unwonted, and responsible duties upon the Board. At this juncture the telegraph wires of the department were cut, and the movement of the railroads and stages violently interrupted, interfering seriously with our accustomed means of transmitting orders and concentrating forces.
