We tend to think of the United States and Canada as natural friends and allies, but the history of their shared border is filled with hilariously bizarre episodes that read like a mix of the Korean DMZ and the Wall from Game of Thrones.

Hilariously Bizarre Border Stories

10 Maine Tries To Start A War, Succeeds In Starting A Bar Brawl

In the 1830s Maine found itself tangled in a bitter border dispute with neighboring New Brunswick. Both sides tried to tax the contested strip and even arrested each other’s officials – one unlucky American was even jailed for whistling “Yankee Doodle Dandy” on the Canadian side. After a few years of this tit‑for‑tat, Maine declared enough is enough and readied a militia of 10,000 men, the flamboyantly named “Red Shirts,” while the federal government looked on with a bewildered shrug.

New Brunswick answered in kind, sending troops to the frontier. Newspapers in the Northeast ran wild, urging an invasion and even suggesting that Maine could conquer Canada in six months and install its governor as president of a new republic. Yet the most dramatic showdown occurred not on a battlefield but in a raucous tavern where British and American soldiers, already a few drinks deep, shouted “Success to Maine!” The resulting brawl left several noses broken and an arm shattered.

When the federal government finally intervened, it sent only three men – General Winfield Scott and two aides – to negotiate a compromise. Maine finally relented after the U.S. produced an old map allegedly drawn by Benjamin Franklin, which was used as leverage to prove the Canadian claim correct. The only casualty of this absurd episode was a farmer who was killed when a celebratory bullet ricocheted off a rock and struck him.

9 Irish Nationalists Accidentally Invade America

After decades of oppression, Irish nationalists formed the Fenian Brotherhood and launched a series of incursions into Canada – the infamous Fenian Raids. In 1866, about 800 men under John O’Neill crossed the border, routed a Canadian force and occupied Fort Erie, sparking dreams of swapping Canada for a free Ireland.

The second wave was halted by the United States, which, after a belated protest from the British, arrested the raiders but let them keep their weapons and even paid for their return home. Undeterred, O’Neill recruited a handful of veterans and set his sights on Manitoba, where he seized an abandoned border fort and looted a trading post – which, thanks to a freshly redrawn survey line, actually sat inside American territory.

The blunder was quickly exposed, prompting the U.S. Army to swoop in and arrest the entire party. The Fenians were left with a lesson: good maps matter.

8 The US Government Made The Same Mistake

In 1816 the United States poured money into building a massive stone fort on Lake Champlain to keep an eye on sneaky British‑Canadians who had used that route during the War of 1812. President James Monroe even visited the site. Two years later, a surveyor realized the fort sat a full kilometer inside Canadian soil.

The embarrassment forced the U.S. to abandon the structure, which earned the nickname “Fort Blunder.” The 1842 Webster‑Ashburton Treaty later declared the land American, but by then the original stones had been scavenged by locals on both sides for homes and barns, so the fort had to be rebuilt from scratch.

7 Canadian Militia Intercept An Arms Shipment In The Most Metal Way Possible

In 1837 a rebellion erupted in Upper Canada, and its defeated rebels fled to the Niagara River islands. Sympathizers in the United States arranged to ship arms to them aboard the steamboat Caroline. The Canadian militia stormed the vessel as it crossed the river, set it ablaze, and sent the burning ship over Niagara Falls – a scene that could have been a lost Motörhead album cover.

Unfortunately, one crew member was killed in the attack, inflaming American public opinion. Both sides dispatched troops to the border, but cooler heads prevailed and a full‑scale war was averted. A year later, Canadian rebel William Johnson’s band retaliated by burning the steamer Sir Robert Peel, and one of the original Caroline attackers was assassinated by Irish‑Canadian rebels.

6 Confederate Spies In Canada Fail Hilariously At Germ Warfare

During the Civil War, Canada became a hotbed for Confederate agents. One plot involved hijacking a Great Lakes passenger ship to free Southern POWs on Johnson’s Island, Ohio, using drugged champagne to incapacitate guards – a plan that collapsed when the inside man was discovered.

Another cell raided St. Albans, Vermont, stealing banks and attempting to torch the town, only to be caught trying to slip back into Canada. A separate scheme tried to burn down New York City with “Greek Fire,” but the conspirators forgot that the incendiary needed oxygen, so the tightly sealed rooms stayed untouched.

The most audacious plan came from future Kentucky governor Dr. Luke P. Blackburn, who attempted to spread Yellow Fever northward by smuggling the clothing of deceased patients across the border. The plot was foiled, and it turned out Yellow Fever spreads via mosquitoes, not garments – a fatal flaw in 19th‑century medical knowledge.

5 The US Builds Secret Airbases In Case It Has To Invade Canada

In the 1930s the U.S. Army drafted “War Plan Red,” a contingency for invading Canada that included bombing Vancouver, Quebec and Montreal, and even using poison gas against Canadian troops. The plan went beyond paperwork when the War Department secured $57 million to construct secret military airfields disguised as civilian airports along the border.

When Congress learned of the hidden bases, a flustered FDR reassured Ottawa that the United States had no invasion intentions, and the Secretary of War issued a public apology. Canada, meanwhile, had its own modest plan – a $1,200 budget that reduced its chief officer to a tourist‑disguised spy gathering maps at gas stations. The Canadian Defense Plan One called for an immediate charge across the border at the first sign of an American invasion, buying time for British allies to arrive.

4 The Hunters’ Lodges

In the 1830s, secret societies called the Hunters’ Lodges (Frères Chasseurs) launched the Patriot War from U.S. soil, hoping to topple what they deemed a corrupt Anglo‑Canadian regime. Their most dramatic moment came at the Battle of the Windmill, where over 250 insurgents seized a sturdy stone windmill in Ontario, holding out against British and Canadian artillery.

The rebels expected reinforcements, but the United States finally stepped in, blocking further crossings. With no fresh troops and heavy artillery bearing down, the remaining Hunters were forced to surrender.

3 The Republic Of Indian Stream

In the early 19th century a tiny community of about 300 souls straddling the New Hampshire‑Quebec line found itself double‑taxed by both American and Canadian authorities. Fed up, the residents declared independence as the Republic of Indian Stream, electing Luther Parker as president.

The fledgling republic existed in a diplomatic limbo for three years because neither New Hampshire nor Quebec wanted to spark a cross‑border war over a handful of taxpayers. The fragile peace shattered in 1835 when Canadian debt collectors arrested a local for a hardware‑store bill. Indian Stream militia stormed into Canada, freed the prisoner, and, before the British could intervene, the legislature voted to rejoin the United States. New Hampshire troops moved in, and the episode faded without a larger conflict.

2 Canada’s Machine Gun‑Based Immigration Policy

During the Yukon gold rush, thousands of American prospectors surged toward the Canadian border, eager to stake claims. The exact line was still fuzzy, and both nations had ignored it until the gold fever erupted. Canadian forces tried to claim the key town of Skagway but were chased off by an angry mob of American miners.

To control the influx, Canada hauled two Gatling guns up the Chilkoot and White Passes, effectively turning the mountain passes into toll gates that only allowed prospectors carrying over a ton of supplies to proceed. The standoff lasted until 1903, when Britain sided with the United States and ceded the disputed territory, a decision that fueled Canadian desires for greater independence.

1 Jay Gould Turns Vigilante, The State Of Minnesota Follows Suit

In 1870 a charismatic con‑man calling himself Lord Gordon‑Gordon duped New York’s elite, including Horace Greeley, and was introduced to the infamous robber baron Jay Gould. Gould, fresh from his 1869 “Black Friday” gold‑market crash, was battling Cornelius Vanderbilt for control of the Erie Railroad.

Gordon‑Gordon claimed his Scottish aristocratic friends could bankroll Gould with $30 million in Erie stock. Blinded by greed, Gould wired a million dollars to the con‑artist, who promptly fled to Manitoba, Canada, promising to invest the money locally.

When Gould realized he’d been scammed, he organized a posse of future Minnesota governors, congressmen, and the Minneapolis mayor to kidnap Gordon‑Gordon and smuggle him across the border. The Mounties intercepted the scheme, leading Governor William Rainey Marshall to threaten an invasion if Canada refused to release the captors.President Ulysses S. Grant intervened, and the Canadian government, unwilling to risk war over a swindler, backed down. The kidnappers were released, and a despondent Gordon‑Gordon, realizing Gould would never stop, hosted a lavish party before ending his own life with a pistol.
