John (John Joseph) Breslin

Born in Drogheda, County Louth, in the 1830s, he was well educated and became a studious reader. He worked as a hospital steward at Richmond Prison in Dublin, where he came into contact with leading Irish nationalist prisoners and quietly began helping the Fenian cause.

He is most remembered for his part in the escape of James Stephens from Richmond Prison in 1865 and, later, for his crucial role in the Catalpa rescue of Fenian prisoners from Fremantle in 1876. Disguised and operating under assumed names, he handled delicate planning on the ground and became known as one of the most resourceful figures in these operations.

After these exploits, he spent time in the United States and remained a respected figure in Fenian circles. Sources differ slightly on details such as his exact birth year and year of death, but they agree on his importance as a brave organizer whose secret work helped shape one of the best-known episodes in nineteenth-century Irish revolutionary history.
