Why was andrew jackson's battle at new orleans unnecessary

Option C.

Explanation:

The treaty of Ghent had already been signed, is the correct answer.

A  peace treaty signed by the U.S.A and the United Kingdom of Great Britain and Ireland to put an end to the War of 1812 is known as the Treaty of Ghent. Signed on 24th December 1814, this treaty re-established relations between the two countries to status quo ante bellum, reviving the boundaries of the two nations to the paths ere the war began on June 1812. It was signed two weeks earlier than the battle at New Orleans took place. Though the battle was won by  Andrew Jackson it did not make a difference in the results of the War of 1812
