Task: Question Generation
Input (English): Passage: In County Wexford, 100-200 Volunteers—led by Robert Brennan, Séamus Doyle and Seán Etchingham—took over the town of Enniscorthy on Thursday 27 April until Sunday. Volunteer officer Paul Galligan had cycled 200 km from rebel headquarters in Dublin with orders to mobilise. They blocked all roads into the town and made a brief attack on the RIC barracks, but chose to blockade it rather than attempt to capture it. They flew the tricolour over the Athenaeum building, which they had made their headquarters, and paraded uniformed in the streets. They also occupied Vinegar Hill, where the United Irishmen had made a last stand in the 1798 rebellion. The public largely supported the rebels and many local men offered to join them. By Saturday, up to 1,000 rebels had been mobilised, and a detachment was sent to occupy the nearby village of Ferns. In Wexford, the British assembled a column of 1,000 soldiers , two field guns and a 4.7 inch naval gun on a makeshift armoured train. On Sunday, the British sent messengers to Enniscorthy, informing the rebels of Pearse's surrender order. However, the Volunteer officers were skeptical. Two of them were escorted by the British to Arbour Hill Prison, where Pearse confirmed the surrender order.
Output (English): How many leaders of the volunteers were there?
