In March 1798, the national executive and its papers were seized in Dublin. Faced with the breaking-up of their entire system, the few leaders at large in the capital, joined by Neilson who had been released in ill health from Kilmainham Prison, resolved, with or without the French, on a general uprising for 23 May. Betrayed by informants, Fitzgerald was mortally wounded on the 19th, and on the 23rd Neilson was re-arrested. Tens of thousands heeded the call, but in what proved to be a series of uncoordinated local uprisings.
