War of 1812: Three weeks of British raids on Fort Schlosser, Black Rock and Plattsburgh, New York commence.

The War of 1812 was fought by the United States and its allies against the United Kingdom and its allies in North America. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.

The United Kingdom of Great Britain and Ireland was the union of the Kingdom of Great Britain and the Kingdom of Ireland into one sovereign state, established by the Acts of Union in 1801. It continued in this form until 1927, when it evolved into the United Kingdom of Great Britain and Northern Ireland, after the Irish Free State gained a degree of independence in 1922.

Fort Schlosser was a fortification built in Western New York in the United States around 1760 by British colonial forces, in order to guard the upper entrance to the portage around Niagara Falls, north of Porter-Barton Dock or Schlosser's Landing along the shoreline with the Niagara River.

Black Rock, once an independent municipality, is now a neighborhood of the northwest section of the city of Buffalo, New York. In the 1820s, Black Rock was the rival of Buffalo for the terminus of the Erie Canal, but Buffalo, with its larger harbor capacity and greater distance from the shores of Canada, a recent antagonist during the War of 1812, won the competition. Black Rock took its name from a large outcropping of black limestone along the Niagara River, which was blasted away in the early 1820s to make way for the canal.
