The first order of the adjutant-general, April 18th, called for "seventeen regiments of infantry or rifles." A second order appeared, on the 25th of the same month, calling for twenty-one regiments more; so that the complete quota of two years' volunteers, in the State of New York, included all regiments, up to the Thirtyeighth. Within a week from the time the Port Chester company was finally mustered into the United States service -- May 22d -- the Thirty-ninth Regiment was mustered in as an additional force, and the term of service of the men enlisted was three, instead of two years. From henceforth the history of the county, during the war, was to become one of quotas to be filled and calls to be met, while the ideas with which the two years' men had gone away, that the struggle would soon be over, had settled down into the sober conviction that the three years' term would be the earliest within which the battle would be terminated.

The Three Years' Voluxteers.-- The first regiment taken into the United States service from the State of New York for the term of three years was mustered in on the 28th of May, 1861. The first identification of Westchester County with the three years' volunteers comes on the rolls of the J^ourth New York Cavalry, which was mustered by companies, beginning August 10 and ending November 15, 1861. The muster-rolls of the regiment disclose the following names :
