What was the turning point of the War of 1812?

The Battle at Fort Meigs was the turning point of the War of 1812, a naval warfare between Britain and the America. It was a very close fight, but with Britain successfully defeating America's naval fleet many times. This war started as a counter to Britain's support of American Indian tribes who were fighting against them, and Britain's motive for war was to serve as a warning to America that they should retract their monetary support towards France, whom Britain are then engaging a war with them at that time.  This threats hit America, and to protect his honor and his sovereignty, and risk further humiliation, America struck back, causing a conflict between the two superpowers.

The battle of Ford Meigs proved to be a crucial pivotal point for USA, as they had already lose many naval battles with Britain, accompanied by losses of many of their ports in the coastal areas. So, for the port Ford Meigs, to prevent it from falling under the hands of the British Empire, they stocked it with defensive power, and put more manpower and machinery to safeguard the sacred place. Despite the attempts made by Britain to capture the port, it proved futile as the port withstand the frenzied attempts of bombardment, the fort still remained strong. The defense was led by Major General Henry Harrison. Knowing that they had already lost Fort Mackinac and Fort Detroit in the Michigan Territory  and also the Ford Dearborn in the Illinois territory, they could not afford to lose more ports or face utter collapse, so their only hope of survival was Ford Meigs.

The battle continued for four days, with no result, and Britain was suffering from many casualties and also from tiredness from the battle, they were forced to retreat to Canada, and this change the whole complexion of battle, leading to America victory.
