Due to the increasing population of the Southern Precinct of Dutchess County and the great distance of these communities from the county seat in Poughkeepsie, Putnam was split from Dutchess in 1812 and organized as an independent county. It encompassed all of the Philipse Patent and the Oblong abutting it, less a triangular area in the farthest northwest reach of the Patent. There, a lowland near Fishkill Creek isolated from the rest of Putnam County and its adjacent upland drainage leading into the Hudson Highlands to the south, were ceded to Dutchess. Putnam travelers mostly used boats and ships along the Hudson River. Boats transporting goods traveled up the Hudson to ports, mainly at Peekskill, New York. They were transported by road into Putnam County, or goods were unloaded in Putnam County at Cold Spring, New York. Such transport suffered in winter, when the river froze. At that time, little food or goods could be shipped to the county.
