Chauncey went on to be Brooklyn's longest serving commandant from July 13, 1807 to May 16, 1813, and again from December 21, 1824 to June 10, 1833. His letters to the Secretary of the Navy provide perhaps the fullest description of the navy by a career naval officer of the early yard. These letters deliver rich detail about the officers and employees, and the problems he encountered making the new yard a viable concern. Writing November 27, 1807, to the Secretary of the Navy, Chauncey pleads for maintenance funds – "The following things are almost indispensable to promote the public service and for the accommodation of the yard. Two wells to be sunk, in the yard, with pumps in them, windows in the armory, a horse & cart to transport stores, fill holes about the wharf &c &c The tide ebbs & flows in 24 hours consequently leaving a dampness that must destroy the timber next to the ground very soon There is sufficient for the horse in the yard Six wheel barrows with more other little conveniences which I will hope you will leave to my discretion I will not abuse you're your confidence." Commodore Chauncey was particularly tough when negotiating wages. Writing on January 5, 1808, to Secretary of the Navy Robert Smith he explained "Some of them (in consequence of Mr. Buckland having mentioned publicly that twenty three gun boats was to be built) immediately had an idea that we could not do without them and would not go to work. I however was able to find a sufficient number willing to work at the reduced wages and these who refused will in a week come back and beg for work and I shall be able to reduce their wages 25 cents more for the merchants have no work for them to do therefore they must either work for us at our price or go unemployed." In May 1829, while in command of the shipyard, Chauncey led a series of searches for the body of
George Washington Adams, who committed suicide by jumping from the deck of the steamship
Benjamin Franklin. In December 1835 Chauncey led navy yard marines and sailors in suppressing the
Great Fire of New York by blowing up buildings in the fire's path. His last service was as member, and, for four years, President, of the Board of Navy Commissioners. Commodore Chauncey died in Washington, on January 27, 1840. ==Legacy==
