New Orleans

Answer 2

There is a good Wikipedia article on the 1812 war (see sources below). That article explains that:
"The war was conducted in four theatres of operations:

1. The Atlantic Ocean
2. The Great Lakes and the Canadian frontier
3. The coast of the United States
4. The Southern States"

If you just want LAND battles, then ignore "1. The Atlantic Ocean".

You will find all the detail you might want about the other 3 fronts in the article.

Answer 3

Lake Erie, northeast Atlantic coast (Washington), New Orleans.

Answer 4

New England, Carolina, and Texas
