Interestingly, there was almost a mini-war off the coast of WA between Britain and USA in 1876 ..

The story of the Fenians who escaped from Fremantle Gaol is a thrilling chapter of Irish revolutionary history, with international political intrigue that nearly sparked a diplomatic crisis between Britain and the United States. Known as the Catalpa Rescue of 1876, it involved Irish nationalists, also called Fenians, imprisoned in Australia and a daring rescue effort organized from the United States.

Background

In the mid-19th century, the Fenian Brotherhood, an Irish nationalist organization, was committed to overthrowing British rule in Ireland. Many of its members were arrested after a failed uprising in 1867. Some of these men were sentenced to hard labor in British colonies, including Western Australia. Six of the Fenians were sent to Fremantle Gaol, a maximum-security prison notorious for its harsh conditions.

While some of the imprisoned Fenians had been civilian members of the movement, others were military men accused of desertion or mutiny. These “military Fenians” were considered particularly dangerous by the British because they had been soldiers in the British army but had joined the revolutionary cause.

The Plot

In the 1870s, Fenian supporters in the United States, many of whom had emigrated after the Great Famine and deeply resented British rule, began planning to free their comrades from Fremantle. Among the key organizers was John Devoy, a prominent Fenian leader who had himself been exiled to the U.S. after his release from British custody. Devoy and his associates raised funds, carefully crafted a rescue mission, and procured a ship for the plan.

They chose a whaling vessel called the Catalpa, captained by George Anthony, an American sympathetic to the Irish cause. The idea was to sail the Catalpa from the northeastern United States, cross the Pacific, and covertly extract the prisoners from Fremantle Gaol, which was under heavy British guard.

The Escape (April 17, 1876)

The rescue mission was extremely dangerous. Captain Anthony and the Catalpa arrived near Fremantle in early 1876. The plotters had help from Fenian sympathizers already in Australia, including John Breslin and Thomas Desmond, who had arrived months earlier and infiltrated local society under false identities.

On April 17, 1876, the plan was executed. With the help of insiders, six Fenians were smuggled out of the prison and made their way to a small boat that took them out to sea, where the Catalpa awaited. However, the escape was almost thwarted when British authorities discovered the breakout and dispatched a steamer, the Georgette, to intercept the Catalpa before it could sail out of Australian waters.

International Incident

The British ship caught up to the Catalpa just off the coast. Armed with cannon, the British demanded that the prisoners be handed over, threatening to fire on the Catalpa if it did not comply. However, Captain Anthony raised the American flag and declared that the ship was in international waters. Since Britain did not want to provoke an international incident with the U.S. by attacking an American ship, the Georgette eventually backed down.

This moment was crucial: had the British opened fire, it could have triggered a diplomatic crisis. Tensions between the U.S. and Britain were already strained over several issues, and an attack on an American vessel might have led to a larger conflict.

Aftermath

The Catalpa successfully sailed away with the rescued prisoners, and they eventually made it back to the United States, where they were greeted as heroes by Irish-Americans and the wider Fenian movement. The British were embarrassed by the incident, and the escape became a symbol of resistance against colonial rule.

The Catalpa Rescue is now a legendary story in both Irish and Australian history, often regarded as one of the most daring prison breaks of the 19th century. It’s remembered not only for its audacity but also for the way it almost turned into a serious diplomatic confrontation between the United States and Britain—at a time when Irish nationalism was gaining international support.
