Throughout all these proceedings, the men acted in the belief that they were doing their best to maintain good order, and, although the committee which had been sent to Harrisburg returned without genuinely reassuring news, no one seemed to have the least idea that the military would be called out. However, the visit of the governor's agent, previously referred to, had already borne fruit when, on the morning of Sunday, July 10, Sheriff McCleary forwarded his final appeal for military aid. In this communication, the sheriff once more averred that his powers were exhausted, and that the civil authorities could not raise a force of deputies large enough to cope with the locked-out men, "Only a large military force," he added, "will enable me to control matters." At 10 o'clock on Sunday night the governor issued the following order: _George R. Snowden, Major-General Commanding N. G. P._: Put the division under arms and move at once, with ammunition, to the support of the sheriff of Allegheny County, at Homestead. Maintain the peace, protect all persons in their rights under the constitution and laws of the state. Communicate with me. ROBERT E. PATTISON, _Governor_. Sheriff McCleary was informed of this order and directed to communicate with General Snowden. Immediately on receipt of his instructions, General Snowden issued orders to the brigade commanders. General Robert P. Dechert, in command of the First Brigade, with headquarters at Philadelphia, was directed to concentrate his brigade in camp at Mt. Gretna, near Lebanon, in the eastern part of the state, by Monday afternoon, battery horsed, and taking three days' rations. General J. P. S. Gobin, of the Second Brigade, was ordered to concentrate his command at Lewiston, moving west. General John A. Wiley, of the Third Brigade, composed of regiments from Western Pennsylvania, was ordered to proceed with his command to a point on the Pennsylvania Railroad within easy reach of the Monongahela River. Within twelve hours from the time when Major General Snowden received the Governor's order the entire National Guard of Pennsylvania was on the march, fully equipped and ready for any kind of service.
