In the fall of 1812, Captain Denniston of the "Republican Blues" enlisted about fifty volunteers to serve one year or during the war, and they elected Jonathan Gidney captain. They formed part of a detached regiment of riflemen of which Captain Denniston became major and afterwards colonel.
A part of a company from Wallkill was included in Colonel Hardenburgh's Ulster regiment, which went to Plattsburgh and thence to Fort Hamilton, near the Canada line, for guard duty.
The following roll of a detached company in Colonel Michael Smith's regiment of infantry, mustered in in September, 1814, embraces men from both Orange and Ulster Counties:

Orange County was represented in the Navy by Silas H. Stringham, Charles Ludlow and Robert C. Ludlow, among others.

After the British captured Washington in 1814, a public meeting was held in Goshen, August 30, to consider the propriety of repairing the fortifications at West Point or erecting new ones for public defense. General James W. Wilson was chairman of the meeting, and a committee to devise and report plans was composed of John Duer, Jonathan Fisk, William Ross, John W. Wilkin, George D. Wickham, James Finch, Jr., and Nathan H. White. They reported at an adjourned meeting, and recommended the following committee of defense, which was appointed:
For Minisink, John Bradner, Nathan Arnot; Deer Park, John Finch, Jr., Joseph Baird; Wallkill, Henry B. Wisner, Benjamin Woodward; Goshen, John Duer, Freegift Tuthill; Warwick, Dr. Samuel S. Seward, Jeffrey Wisner; Monroe, James D. Secor, Benjamin Cunningham; Cornwall, William A. Clark, Joseph Chandler, Jr.; Blooming Grove, Col. Selah Strong, Jeremiah Horton; Montgomery, John Blake, Jr., Johannes Miller; Newburgh, John D. Lawson, Jacob Powell; New Windsor, Joseph Morton, David Hill.
This Committee of Defense met September 7, and made Selah Strong its chairman and John Duer its secretary. It passed resolutions in harmony with those of the public meeting, and appointed the chairman, the secretary, William A. Clark, Joseph Morell and Johannes Miller a committee to tender the services of citizens in repairing the West Point fortifications. At another meeting, September 17, the committee instructed the town committees immediately to collect subscriptions of money and labor, and report them to the General Committee, and also inquire into and report the quantity of arms and ammunition which the respective towns might need.
October 25 it was reported from the Secretary of War that he would send a skillful engineer to West Point "to superintend the works and point out the sites most eligible for defense."
