Incorrect; a common misconception. The treaty was agreed to but never signed / ratified until April 1815, Approximately 3-4 months after the “Battle of New Orleans.” You are correct that poor communications were a factor; if word had reached the US and British, the battle would probably not have occurred. Most historians agree that had the Brits won the Battle at New Orleans, they would have controlled all of the Mississippi Valley, including all of the lands that encompassed the LA Purchase in 1803. The Brits already had a strong foothold in Canada and most of the Atlantic Coast after repeated battles throughout the war of 1812. Bottom line is that if the US lost the Battle of New Orleans, the Brits would have ignored the verbal peace accord. Further proof was that the Brititsh navy and army took up a position on Dauphin Island (off the coast of AL) to regroup after they retreated from New Orleans. They over ran a fort at Mobile Bay and did not depart from the Gulf until May of 1815 until after the treaty was finalized, ratified, and signed by both countries. There are several good books on the subject, if you’re a history buff.Don't think it would have made a difference as the "Battle of New Orleans" was only a practice battle fought after the peace was signed. Poor communications back in the day.
