The 17th was mustered into the U. S. service between Nov. 13, 1862, and Jan. 10, 1863, but the organization was not completed, the men were transferred to the 2nd N. H. infantry, and the officers were mustered out on April 16, 1863. The regiment numbered 216 and lost by death 4 men. Under the president's call for troops of Aug. 4, 1862, New Hampshire was required to furnish three regiments, one to be organized in each congressional district. 791 men from the 3d district volunteered, who should have been assigned to the 17th regiment, but the 15th and 16th regiments were not yet complete, and, as the call was urgent, men were transferred from the 17th to fill these regiments. Other volunteers joined the 17th, but not enough to enable it to take the field as a separate organization and they were assigned to the 2nd infantry, as above stated. By Act of Congress in 1892, the 17th was recognized as a regiment and its status determined beyond question.
The compiled service records of this unit contains 229 men.
