The Pig War (1859)

A boundary dispute on San Juan Island nearly escalated into a U.S.-British war after an American farmer shot a British-owned pig that was rooting in his garden . Troops rushed in, tensions rose, and both sides came to the verge of open conflict.

Thankfully, the "war" ended without a single human casualty. Diplomacy prevailed, leaving history with a famously absurd standoff where the only fatality was the unfortunate hog that started it all.

The Toledo War (1835-36)

Believe it or not, Michigan and Ohio once squared off over a slim strip of land containing the city of Toledo . Militias mobilized, tempers flared, and political rhetoric soared past anything that the dispute really deserved.

The conflict produced only one injury: a sheriff was stabbed with a pocket knife. It ended with Michigan receiving the Upper Peninsula as compensation.

3

The Aroostook War (1838-39)

A mix of lumberjacks, militias, and confused officials sparked a border showdown between Maine and British Canada. Though the name sounds dramatic, the "war" consisted mostly of shouting, arrests, and paperwork .

Battle of Blair Mountain (1921)

For five tense days in West Virginia, thousands of coal miners armed themselves against hired gunmen, local law enforcement, and eventually federal troops . It became the largest labor uprising in U.S. history.

Despite its scale, the conflict ended quickly once the Army intervened. Its strange blend of union struggle, machine guns, and biplanes made it one of the most dramatic yet short-lived labor battles ever fought.

6

Battle of Athens, Tennessee (1946)

World War II veterans took matters into their own hands and clashed with a corrupt county political machine after years of election wrongdoing. In a single night of gunfire and sieges, the veterans seized the jail and exposed the fraud .

7

Shelling of Fort Stevens (1942)

During World War II, a Japanese submarine surfaced off the Oregon coast and fired on Fort Stevens for roughly fifteen minutes . The startled gunners held their fire to avoid revealing their positions.

No lives were lost, and damage was minimal. Still, the brief attack stands out as one of the only direct assaults on the U.S. mainland during the war.

8

Battle of Palmito Ranch (1865)

Fought in Texas weeks after the Confederacy had effectively collapsed, this short skirmish featured U.S. and Confederate troops battling despite the war’s official end . Confusion and poor communication kept the fighting alive.

The engagement lasted only a few hours but became the Civil War’s final battle. Its odd timing makes it a historical footnote with a bizarre twist.

11

Little Belt Affair (1811)

This brief naval encounter between USS President and HMS Little Belt lasted less than an hour. Confusion over signals led to sudden gunfire and heavy damage to the British vessel.

The brief clash worsened tensions between the two nations and helped push the U.S. and Britain toward the War of 1812.

This term originated as an English rendering of a Native American expression for wartime mobilization—specifically the route or course taken toward an impending conflict.

Euro-American settlers later adopted the phrase, and by the late 19th, century newspapers were using it metaphorically to describe anyone behaving aggressively or angrily.

4

Branding iron

Saloon bars on the frontier often lacked stools, so patrons had to stand and lean their bellies directly against the counter.

The phrase soon came to mean approaching something boldly, whether at a bar or any other challenge.

8

Kick the bucket
