About Seán Heuston
Lived 1891 – 1916 (aged 25). Seán Heuston was an Irish military personnel, politician and rebel.
Early life Heuston was born at Gloucester Street in Dublin on 21 February 1891, the son of clerk John Heuston and Maria McDonald. The family was Irish Catholic, but bore the English-language surname Heuston from the time of Seán's grandfather's enlistee service in the British Army in the years following the Irish Potato Famine in the mid-1800s. The name Heuston was originally brought to Ireland from the Scottish Barony of Lanarkshire during the time of the settlement of the Ulster Plantation.
Educated by the Christian Brothers, he joined Great Southern and Western Railway where he worked as a railway clerk in Limerick. While there he joined Fianna Éireann, of which he was an active member. Seán Heuston arranged for members who could not afford to buy their uniforms to do so by paying small weekly sums. Under his guidance the Fianna in Limerick had a course which encompassed not only drilling, including signalling, scout training and weapons training, but also lectures on Irish history and Irish classes. In 1913, Heuston was transferred by GS&WR to Dublin, where he joined Emmet Sluagh. He was Director of Training for Fianna Eireann as well as being Vice-Commandant of the Dublin Battalion and Commander of its 6th Company from August 1915 to Easter 1916. He joined the Irish Volunteers, becoming Captain of D Company, 1st Battalion.
Easter Rising Heuston was the Officer Commanding the Irish Volunteers assigned to hold the Mendicity Institution (now called Heustons Fort Acting under orders from James Connolly, Heuston was to hold this position for three or four hours, to delay the advance of British troops. This delay was necessary to give the headquarters staff time to prepare their defences. Having successfully held the position for the specified period, he was to go on to hold it for over two days, with twenty-six Volunteers. With his position becoming untenable against considerable numbers, and the building almost completely surrounded, he sent a dispatch to Connolly informing him of their position. The dispatch was carried by two Volunteers, P. J. Stephenson and Seán McLaughlin, who had to avoid both sniper fire and British troops across the city. It was soon after sending this dispatch that Heuston decided to surrender.
The Surrender
Séamus Brennan, a member of the Mendicity Institution Garrison under Heuston, gave the following account of the decision to surrender: Our tiny garrison twenty-six—had battled all morning against three or four hundred British troops. Machine-gun and rifle fire kept up a constant battering of our position. Seán visited each post in turn, encouraging us. But now we were faced with a new form of attack. The enemy, closing in, began to hurl grenades into the building. Our only answer was to try to catch these and throw them back before they exploded. Two of our men, Liam Staines and Dick Balfe, both close friends of Seán's were badly wounded doing this. We had almost run out of ammunition. Dog-tired, without food, trapped, hopelessly outnumbered, we had reached the limit of our endurance. After consultation with the rest of us, Seán decided that the only hope for the wounded and, indeed, for the safety of all of us, was to surrender. Not everyone approved but the order was obeyed and we destroyed as much equipment as we could before giving ourselves up... Father Albert concluded:
