It seems to me as if this article is somewhat biased in its summary, since the statement that the Battle of Plattsburgh resulted in the repulse of British invasions implies that hostilities in the War of 1812 were initiated by the British.   

 In fact, the U.S. declared war first on the British on June 18, 1812, with expressed intentions of attacking and occupying parts of Upper and Lower Canada.  The operations on Lake Champlain and near Plattsburgh were part of the War of 1812, as Plattsburgh had been used as a starting point for U.S. troops unsuccessful attack on Montreal earlier. 

 To me the article comes across as having a bias for the U.S. POV    James
