The Young Irelander Rebellion was a failed Irish nationalist uprising led by the Young Ireland movement. It took place on 29 July 1848 in the village of Ballingarry, County Tipperary. After being chased by a force of Young Irelanders and their supporters, a Royal Irish Constabulary unit raided a house and took those inside as hostages. A several-hour gunfight followed, but the rebels fled after a large group of police reinforcements arrived.

It is sometimes called the Famine Rebellion (since it took place during the Great Irish Famine) or the Battle of Ballingarry.

Origins:

1848 was a year of revolutions throughout continental Europe. In February 1848, King Louis-Philippe of France was overthrown and the Second Republic was proclaimed in Paris. This revolution sent political shock waves across Europe, and revolutions broke out in Berlin, Vienna, Rome, Prague, and Budapest. At least temporarily, absolutist governments were replaced by liberal administrations, near universal suffrage was introduced and elections were held to constituent assemblies to draw up new national constitutions. It was sometimes described as the "springtime of the people."
Inspired by these events and the success of liberal, romantic nationalism on the European mainland and disgusted by Daniel O'Connell's acceptance of patronage from the British Liberals, a group calling themselves the Irish Confederation broke away from O'Connell's Repeal Association' They took an uncompromising stand for a national Parliament with full legislative and executive powers. At its founding, the Confederation resolved to be based on principles of freedom, tolerance and truth. While the young men did not call for rebellion, neither would they make absolute pledges for peace. Their goal was independence of the Irish nation and they held to any means to achieve that which were consistent with honour, morality and reason. The Young Irelanders, as they had become known, longed to see achieved in Ireland the liberties achieved on the Continent.

Leaders William Smith O'Brien and Thomas Francis Meagher led a delegation to Paris to congratulate the new French Republic. Meagher returned to Ireland with a tricolour flag (now the national flag) - a symbol of reconciliation between the Orange and Green, made for them by French women who sympathized with their cause.
Since most of the continental revolutions were relatively bloodless, O'Brien believed he could attain similar results in Ireland. He hoped to unite Irish landlords and tenants in protest against British rule. The government, however, forced the leaders' hands on 22 July 1848 by announcing the suspension of habeas corpus. This meant they could imprison the Young Irelanders and other opponents on proclamation without trial. Having to choose between armed resistance or an ignominious flight, O'Brien decided that the movement would have to make a stand.
Rebellion:

From the 23rd to the 29th of July 1848, O'Brien, Meagher and Dillon raised the standard of revolt as they travelled from County Wexford through County Kilkenny and into County Tipperary. The last great gathering of Young Ireland leaders took place in the village of The Commons on July 28. The next day, O'Brien was in The Commons where barricades had been erected, near the Commons colliery, to prevent his arrest. His local supporters - miners, tradesmen and small tenant farmers - awaited the arrival of the military and police. As the police from Callan approached the crossroads before The Commons from Ballingarry, they saw barricades in front of them and, thinking discretion the better part of valour, they veered right up the road toward County Kilkenny. The rebels followed them across the fields. Sub-Inspector Trant and his 46 policemen took refuge in a large two-storey farmhouse, taking the five young children in the house as hostages. They barricaded themselves in, pointing their guns from the windows. The house was surrounded by the rebels and a stand-off ensued. Mrs. Margaret McCormack, the owner of the house and mother of the children, demanded to be let into her house, but the police refused and would not release the children. Mrs. McCormack found O'Brien reconnoitring the house from the out-buildings, and asked him what was to become of her children and her house.
O'Brien and Mrs. McCormack went up to the parlour window of the house to speak to the police. Through the window, O'Brien stated, "We are all Irishmen - give up your guns and you are free to go." O'Brien shook hands with some of the police through the window. The initial report to the Lord Lieutenant of Ireland stated that a constable fired the first shot at O'Brien, who was attempting to negotiate. General firing then ensued between the police and the rebels. O'Brien had to be dragged out of the line of fire by James Stephens and Terence Bellew MacManus, both of whom were wounded.
The rebels were incensed that they had been fired upon without provocation ,and the shooting went on for a number of hours. During the initial exchange of fire, the rebels at the front of the house - men, women and children - crouched beneath the wall. So great was the pressure of the crowd that one man, Thomas Walsh, was forced to cross from one side of the front gate to the other. As he crossed between the gate piers he was shot dead by the police. During lulls in the shooting, the rebels retreated out of the range of fire. Another man, Patrick McBride, who had been standing at the gable-end of the house when the firing began - and was quite safe where he was - found that his companions had retreated. Jumping up on the wall to run and join them, he was fatally wounded by the police.
It was evident to the rebels that the position of the police was almost impregnable, and a Catholic clergyman of the parish, Rev. Philip Fitzgerald, endeavoured to mediate in the interests of peace. When a party of the Cashel police under Sub-Inspector Cox were seen arriving over Boulea Hill, the rebels attempted to stop them even though they were low on ammunition, but the police continued to advance, firing up the road. It became clear that the police in the house were about to be reinforced and rescued. The rebels then faded away, effectively terminating both the era of Young Ireland and Repeal, but the consequences of their actions would follow them for many years.
Aftermath

Several of the rebel leaders were charged and convicted of sedition, which carried a death sentence. Their sentences were commuted to transportation to Van Diemen's Land in present-day Tasmania, Australia, where the "Irish gentlemen" prisoners were separated among various settlements. Meagher and John Mitchel (who had been transported there before for political activities) both managed to escape and emigrate to the United States in the early 1850s. They served on opposite sides of the American Civil War: Meagher with the Union, for which he recruited and commanded the Irish Brigade, and Mitchel's allying with and living in the South, sending three sons to fight with the Confederacy.

The McCormack family emigrated to the USA about 1853.

Since that time, the McCormack house (which was owned by numerous other families after 1848) has always been known locally as the Warhouse.

In 2004 the State decided on "Famine Warhouse 1848" as the official name of the house, which had been designated a national heritage monument.
