Considering that the “Battle of New Orleans” happened several months AFTER the treaty of Ghent was signed, it makes little sense that someone would celebrate nearly destroying a hard-fought peace treaty.

[Rockingham]

Until implemented, the peace treaty was notional, with the British expedition to take New Orleans launched during peace negotiations and with orders to disregard any rumors of a peace. If the British had won the Battle of New Orleans, they could have tried to keep the city so as to constrain US expansion or demanded compensation or diplomatic concessions for its return to the US.

Moreover, the casualties the British suffered in the battle of New Orleans from a militia general leading an improvised force marked the US as a tougher adversary than previously credited. That helped to set the US on firmer ground with the British in the ensuing decades.

Remember, that was back before Al Gore.
