1. George Washington, Revolutionary War
2. Andrew Jackson, War of 1812
3. William Henry Harrison, War of 1812
4. Zachary Taylor, Mexican War
5. Franklin Pierce, Mexican War
6. Andrew Johnson, Civil War
7. Ulysses Simpson Grant, Civil War
8. Rutherford Birchard Hayes, Civil War
9. James Abram Garfield, Civil War
10. Chester Allan Arthur, Civil War
11. Benjamin Harrison, Civil War
12. Dwight David Eisenhower, World War II
But, nonetheless, I like your paranoid reasoning of why they made the mistake.
