Question

why was the battle of new orleans fought after the war had officially ended?

jackson ignored orders

the treaty had been canceled

news of the treaty had not reached louisiana

britain restarted the war

Explanation:

The Battle of New Orleans (part of the War of 1812) occurred after the Treaty of Ghent (which ended the war) was signed because communication was slow. The news of the treaty had not reached Louisiana in time, so the battle was fought unaware of the war's official end. Jackson didn't ignore orders, the treaty wasn't canceled, and Britain didn't restart the war.

Answer:

C. News of the treaty had not reached Louisiana
