The victory at the "Battle of New Orleans" was an overwhelming one for the Americans. The British lost about 2,000 men the Americans about 70. A decisive enough victory to make a good song even telling the truth.

It was completely unnecessary to wrongly impugn the courage of the enemy who were to all practical purposed wiped out while attacking.
It makes the song a lie, it makes Jimmy Driftwood a liar and it detracts from the honor of the American victory and of those who fought the battle.

The song should be ignominiously forgotten.
