In April 1875, the American whaling barque Catalpa quietly slipped out of New Bedford harbour without ceremony. To all appearances, she was just another whaler embarking on a routine hunt in the North Atlantic. However, Captain George Anthony had orders to sail halfway around the world and be stationed off Australia’s west coast, ready to rescue six convicts imprisoned by the British in Fremantle.
The prisoners were all Irish nationalists who had been found guilty of treason and sent to Fremantle eight years earlier with scores of other revolutionaries. Over the years, most had been pardoned, but these six men had been serving soldiers in the British Army, and the government was disinclined to let them go. However, an Irish Independence organisation in the United States, the Clan-na-Gael, formulated a plan to set them free.
They purchased the whaler, recruited a captain sympathetic to their cause and sent Irish agents, headed by John Breslin, to Fremantle to organise the escape on the ground. Breslin passed himself off as a wealthy American businessman looking for investment opportunities in the far-flung colony. He made contact with the convicts and warned them to be ready to leave at short notice. Breslin then assembled a small armoury of firearms and organised the hire of horses and carriages. He also reconnoitred the coastline south of Fremantle, looking for a suitable out-of-the-way place to take the escapees. There they would be taken off the beach in a whaleboat and delivered to the waiting ship.

By January 1876, all was in place except for the Catalpa. The ship was nowhere to be seen. As the weeks ticked by without any word from the whaler, Breslin grew increasingly concerned that some calamity had befallen her. However, his fears were unfounded. To Breslin’s great relief, the Catalpa finally dropped anchor in Bunbury on 28 March.
Breslin met with Captain Anthony, and the two men thrashed out the final details of the escape. And, after a couple of unavoidable delays, the pair set on the escape, taking place on Monday, 17 April. On Sunday night, Captain Anthony took the Catalpa into international waters 30 kilometres west of Rockingham and then went ashore in the whaleboat to wait for Breslin and the Irish prisoners at a prearranged beach near Cape Peron.
On Monday morning, the prisoners left their work gangs on various pretexts and made their way to Rockingham Road. There, they were met by Breslin and his men waiting with a change of clothes and horse-drawn carriages. They then raced south towards the waiting whaleboat. By 10.30, the prisoners, Breslin and all his men, were being loaded onto one of the Catalpa’s whaleboats as a plume of dark smoke from the government steamer smudged the morning sky. Captain Anthony wasted no time heading the boat out to sea to rendezvous with his ship.
However, it would not be smooth sailing getting back to the Catalpa. The seas had turned rough while he had been waiting on shore. To make matters worse, the whaleboat sat low in the water, weighed down by so many extra bodies. The boat crew battled the wind and waves all that day but made slow progress. But towards sunset, Captain Anthony spotted the Catalpa off in the distance. Then disaster struck. The mast snapped under the strain of the taut canvas and nearly flung everyone into the ocean. But for the quick actions of the man at the tiller, the brazen escape may well have failed there and then. Once night had descended and the ship was lost to sight, they had no choice but to spend an uncomfortable night in the cramped boat being buffeted about by the ocean swells. The next morning, the mast was repaired, and they were once again on their way. They soon sighted the Catalpa again and set a course to join her. Captain Anthony also spotted billowing black smoke, heralding the government steamer Georgette, on a course to intercept the whaler. Captain Anthony had the sail taken in and the mast lowered. The steamer passed within one kilometre of the whaleboat but failed to see it in the choppy sea conditions.

When the Georgette came alongside the Catalpa, the Superintendent of the Water Police enquired if there were any escaped prisoners on board. On being told there were none, the police officer asked if he could come aboard so he could see for himself. The first mate forbade him permission, reminding the Superintendent that the Catalpa was an American-flagged ship in international waters and was therefore not subject to British authority. Not wishing to spark an international incident, the Georgette broke off after 10 minutes and continued its fruitless search for the missing prisoners.
As the Georgette steamed off, Captain Anthony had the mast and sail reset, and his oarsmen pulled for all they were worth. When the first mate sighted the whaleboat in the distance, he ordered the Catalpa’s helmsman to head towards them to close the gap. Hidden from sight by the bulk of the ship, Captain Anthony was unaware that a police cutter was also making for the ship.
The whaleboat reached the Catalpa first and was hooked up to the davits, and within minutes, they were underway again and heading north. It was a close-run race. But, in the end, the police could do nothing but watch on as several of the Irish convicts jeered at them from the safety of the American ship’s deck. The police cutter’s commander gracefully accepted defeat with a snappy salute before returning to Fremantle empty-handed. However, the Western Australian Governor was less sanguine about losing six prisoners so easily. He ordered the Georgette to go back out, find the ship and return the six prisoners to gaol. This time, she would carry a large complement of armed police and prison guards as well as a field artillery piece mounted on the foredeck. The next morning, the Georgette intercepted the Catalpa in international waters for the second time. This time, the Catalpa was heading south past Fremantle on her way towards the Southern Ocean to start her long voyage home.

At 8 a.m., the Georgette pulled a little ahead of the Catalpa and fired a shot across her bows, signalling for the whaling ship to stop. Captain Anthony ignored the order and continued on his course until the Georgette’s gun crew had reloaded their piece. Only then did he put a speaking trumpet to his mouth and ask what they wanted.
The Georgette’s Commanding Officer asked if there were any escaped prisoners onboard. This time, he warned Captain Anthony that the colonial secretary had been in contact with the American Government and had been authorised to use force to stop the ship. He also threatened to bring down the Catalpa’s masts with artillery fire should they not heave to. Breslin and Anthony agreed to call the bluff, thinking it unlikely that they had got permission to board, even with the magic of telegraphic communications. Anthony pointed to the Stars and Stripes fluttering in the wind and cautioned that an attack on his ship would be an attack on the United States.
No one on the steamer wished to trigger a diplomatic row, so after shadowing the Catalpa for another half an hour or so, the Georgette veered off and returned to port empty-handed. Breslin would later write that the British left without even bidding them a hearty bon voyage.
The Catalpa arrived in New York on 19 August after a four-month voyage via Cape Horn. The rescuers were feted as heroes, and the six Irish prisoners settled into their new lives as free men. This was arguably one of the best planned and executed escapes during Australia’s convict era. It was also the last.
