Description: Fort Pike: 1812-1815, Jefferson County, Sacketts Harbor. Hastily prepared earthen works named Fort Volunteer were established at the start of the War of 1812 to defend the Northeast end of Sacketts Harbor (East side of Black River Bay). A new set of breastworks and a blockhouse were constructed adjacent and named for General Zebulon M. Pike. Included a 2 story blockhouse with 20 cannons, and barracks for 2,000. Later, Volunteer and Pike became the nucleus of Madison Barracks. See map at Sacketts Harbor Forts.
