Why was andrew jackson's battle at new orleans unnecessary? the americans had already won the war with a victory in new york. the british had already won the war after attacking maine. the native americans were planning to surrender the land. the treaty of ghent had already been signed.

Andrew Jackson's battle at New Orleans was unnecessary because the treaty of Ghent, which ended the war, had already been signed two weeks before hand.

The correct answer is D) The Treaty of Ghent had already been signed.

The Treaty of Ghent was the agreement that officially ended the War of 1812 between the United States and Great Britain. This was signed two weeks before the Battle at New Orleans even took place. Even though Andrew Jackson won this battle for America, it did not make a difference in the outcome of the War of 1812.

However, this battle would propel Andrew Jackson to national fame.

they gained popular support by speaking out against communists
