The History Channel is a joke - a while back they were advertising a series on The Battle of New Orleans and in the background they were playing “Dixie” ... Dixie wasn’t written until 1859 .... the Battle of New Orleans took place in 1810 or there abouts ....
Glass houses.. stones. Since the Battle of New Orleans was fought after the War of 1812 officially ended, although word had not made it to the forces in the field, you know it had to be at least 1812, even if one cannot remember the exact date, as I cannot, without looking it up. Which is easy these days. The battles in Louisiana occurred in December of 1814 and January of 1815. Of course if I'd thought a moment, the words to the song would have come to me .."In 1814 we took a little trip.." of course I'd still have checked.
