The war of 1812 is over looked. 2/3 of all American soldiers deaths were Kentucky folks. The second war of independence is overlooked and the history books only are concerned with the burning of DC.
I believe we lost EVERY land battle in that one - yet prevailed in every naval battle (birth of the legend of ol ironsides?)
Only time we fought Canada too i think - ?
Napoleon was raging around the same time so england had their hands full with "the little corporal"
Korean war often described as "the forgoing war" -- we were VERY close to dropbox hydrogen bombs on Chinese forces (my dad was a B29 crew member whos plane was sent i theater to Japan i believe)
Eisenhower single handedly backed down several memories of his cabinet who insisted we drop the new weapon -
