Ya, but......... If the battle had no impact on the outcome, then nothing after your first sentence would have been able to take place.

more from wiki (God forgive me): re Battle of New Orleans

A general ceasefire had already been declared by the Treaty of Ghent, signed on 24 December 1814, but as peace was not yet ratified in Washington as required by the treaty, the nations were still formally at war. The news of the treaty did not reach the combatants until February, several weeks after the battle.

What I described occurred before the Battle of New Orleans. The Battle of Horseshoe Bend was nine months before New Orleans. As for its effect on the Treaty of Ghent, it had none. It was quickly ratified for the simple reason the country was virtually broke by that time. Madison and Congress knew we did not have the financial wherewithal to last another year of warfare. As for Britain, they saw no benefit to themselves of continuing the war with Napoleon defeated, and the reactionary powers Russia, Prussia, and Austria looming on the horizon.
