The Destruction of the Caroline by George Tattersall

The Caroline affair (also known as the Caroline case) was a diplomatic crisis beginning in 1837 involving the United States, Britain, and the Canadian independence movement. It began in 1837 when William Lyon Mackenzie and other Canadian rebels, commanding the ship Caroline, fled to an island in the Niagara River, with support from nearby American citizens. British forces then boarded the ship, killed an American crew member in the fighting, and then burned the ship and sent it over Niagara Falls.

This action outraged the United States. In retaliations, a group of American and Canadian raiders attacked a British ship and destroyed it. There were several other attacks in 1838 between the British and Americans. The diplomatic crisis was defused by the negotiations that led to the Webster-Ashburton Treaty in 1842, where both the Americans and British admitted to wrongdoing.

In the aftermath, the incident led to the legal principal of the Caroline test. The principle states that the necessity for preemptive self-defense must be "instant, overwhelming, and leaving no choice of means, and no moment for deliberation", as formulated by Daniel Webster in his response to British claims that they attacked the Caroline in self-defense. The Caroline test remains accepted as part of international law today. In 2008, Thomas Nichols wrote:

Background[edit]

The Reform Movement of Upper Canada (today's Ontario) was a movement to make the British colonial rule in Canada more democratic and less corrupt. William Lyon Mackenzie was one of the key leaders of this movement. He was repeatedly elected to serve in a hostile parliament that repeatedly ejected him for his reform efforts. By 1837, Mackenzie has given up on peaceful means for reform and began to prepare for an uprising.

In December of 1837, Mackenzie began the Upper Canada Rebellion by fighting the British in the Battle of Montgomery's Tavern. Mackenzie's forces were seriously outnumbered and outgunned, and they were defeated in less than an hour. He also suffered another major defeat a few days later in London. After these defeats, Mackenzie fled to Navy Island in the Niagara River, which they declared the Republic of Canada, on board the vessel SS Caroline.

Throughout these events, the Canadian rebels enjoyed widespread support from the Americans, who provided them supplies and bases from which to launch raids on the British.

Events[edit]

The body of Durfee, illustrated in 1885

On December 29, 1837, while the Canadian rebels were on Navy Island, n December 29, 1837, Canadian loyalist Colonel Sir Allan MacNab and Captain Andrew Drew of the Royal Navy commanding a party of militia, acting on information and guidance from Alexander McLeod that the vessel belonged to Mackenzie, crossed the international boundary and seized the Caroline, chased off the crew, towed her into the current, set her afire, and cast her adrift over Niagara Falls, after killing one black American named Amos Durfee in the process. His body was later exhibited in front of a recruiting tavern in Buffalo, New York.

Minister H. S. Fox, in an 1841 letter to John Forsyth, summarized the British justification for the incursion: "The steamboat Caroline was a hostile vessel engaged in piratical war against her Majesty's people...it was under such circumstances, which it is to be hoped will never recur, that the vessel was attacked by a party of her Majesty's people, captured and destroyed."[2]

US newspapers falsely reported "the death of twenty-two of her crew" when in fact, only Durfee was killed. Public opinion across the United States was outraged against the British. President Martin Van Buren protested strongly to London, but was ignored.

On May 29, 1838, 13 raiders, mostly Canadian and American refugees from the 1837 rebellion, led by American William "Pirate Bill" Johnston,[3] retaliated by capturing, looting, and burning the British steamer Sir Robert Peel while she was in U.S. waters. President Martin Van Buren sent General Winfield Scott to prevent further incursions into Canada.[4] However, there were several other attacks, the biggest being the Battle of the Windmill in November 1838.

Later that year, Irish-Canadian rebel Benjamin Lett murdered a loyalist, Captain Edgeworth Ussher, who had been involved in the incident.

The case was finally disposed of by U.S. Secretary of State Daniel Webster and Alexander Baring, 1st Baron Ashburton, in the course of their negotiations leading to the Webster–Ashburton Treaty of 1842. Secretary Webster admitted that the employment of force might have been justified by the necessity of self-defence, but denied that such necessity existed, while Lord Ashburton, although he maintained that the circumstances afforded excuse for what was done, apologized for the invasion of United States territory.[5]

Aftermath[edit]

Shortly after the incident, an Canadian sheriff named Alexander McLeod claimed that he had helped attack the Caroline during the Caroline affair. McLeod was arrested in the United States in 1840 for his role in Durfee's death during the attack. This caused yet another international incident, as the British demanded his release, stating that he should not be held criminally responsible for following orders. The trial attempted to identify who exactly had shot Durfee, but this proved futile. McLeod was acquitted of all charges as witness statements made it clear that he had no involvement in the incident.

Anticipatory self-defense[edit]

This incident has been used to establish the principle of "anticipatory self-defense" in international politics, which holds that it may be justified only in cases in which the "necessity of that self-defense is instant, overwhelming, and leaving no choice of means, and no moment for deliberation". This formulation is part of the Caroline test. The Caroline affair is also now invoked frequently in the course of the dispute around preemptive strike (or preemption doctrine).[6]
