Thomas H. O'Shea

During the civil war, he moved headquarters from the Midleton police barracks to Lord Barrymore's estate at Fota Island after the expulsion of Irish Free State forces.

Even as the Free State gained strength and the IRA forces waned, O'Shea continued to engineer bombings, notably at two bridge approaches to Cobh at Belvelly and Fota.

O'Shea led a 2nd hunger strike in October 1923 with Frank Oakley at Mountjoy Prison that, despite Irish Free State media suppression, spread across Ireland with 8000 jailed strikers participating.

By early 1932 O'Shea was involved with the expat movement Clan na Gael, attempting to organize New York City subway workers while being current employees of the Interborough Rapid Transit Company.

The TWU declared its aim to represent all public transit workers in the city, regardless of craft and fight all wages cuts and many of the unions early clandestine meetings took place at O'Shea's apartment in the Bronx.

Growing dissolution with the Communist Party, a tendency to advocate for violence as an organizing device and losing the presidency to Quill led to O'Shea's expulsion from the union.

In 2013, O'Shea's work as a union activist was posthumously honored with an Irish Echo Labor Award during a ceremony at the Sheraton New York Times Square Hotel.
