The burning of Cork by British forces takes place on the night of December 11, 1920, during the Irish War of Independence. It follows an Irish Republican Army (IRA) ambush of a British Auxiliary patrol in the city, which wounds twelve Auxiliaries, one fatally.

IRA intelligence establishes that an Auxiliary patrol usually leaves Victoria Barracks (in the north of the city) each night at 8:00 p.m. and makes its way to the city centre via Dillon’s Cross. On December 11, IRA commander Seán O’Donoghue receives intelligence that two lorries of Auxiliaries will be leaving the barracks that night and travelling with them will be British Army Intelligence Corps Captain James Kelly.

A unit of six IRA volunteers commanded by O’Donoghue take up position between the barracks and Dillon’s Cross, a “couple of hundred yards” from the barracks. Their goal is to destroy the patrol and capture or kill Captain Kelly. Five of the volunteers hide behind a stone wall while one, Michael Kenny, stands across the road dressed as an off-duty British officer. When the lorries near he is to beckon the driver of the first lorry to slow down or stop.

At 8:00 p.m., two lorries, each carrying 13 Auxiliaries, emerge from the barracks. The first lorry slows when the driver spots Kenny and, as it does so, the IRA unit attacks with grenades and revolvers. The official British report says that 12 Auxiliaries are wounded and that one, Spencer Chapman, a former Officer in the 4th Battalion London Regiment (Royal Fusiliers), dies from his wounds shortly after. As the IRA unit makes its escape, some of the Auxiliaries fire on them while others drag the wounded to the nearest cover: O’Sullivan’s pub.

The Auxiliaries break into the pub with weapons drawn. They order everyone to put their hands over their heads to be searched. Backup and an ambulance are sent from the nearby barracks. One witness describes young men being rounded up and forced to lie on the ground. The Auxiliaries drag one of them to the middle of the crossroads, strip him naked and forced him to sing “God Save the King” until he collapses on the road.

Angered by an attack so near their headquarters and seeking retribution for the deaths of their colleagues at Kilmichael, the Auxiliaries gather to wreak their revenge. Charles Schulze, an Auxiliary and a former British Army Captain in the Dorsetshire Regiment during World War I, organizes a group of Auxiliaries to burn the centre of Cork.

At 9:30 p.m., lorries of Auxiliaries and British soldiers leave the barracks and alight at Dillon’s Cross, where they break into houses and herd the occupants onto the street. They then set the houses on fire and stand guard as they are razed to the ground. Those who try to intervene are fired upon and some are badly beaten. Seven buildings are set on fire at the crossroads. When one is found to be owned by Protestants, the Auxiliaries quickly douse the fire.

British forces begin driving around the city firing at random as people rush to get home before the 10:00 p.m. curfew. A group of armed and uniformed Auxiliaries surround a tram at Summerhill, smash its windows, and forced all the passengers out. Some of the passengers, including at least three women, are repeatedly kicked, hit with rifle butts, threatened, and verbally abused. The Auxiliaries then force the passengers to line up against a wall and search them, while continuing the physical and verbal abuse. Some have their money and belongings stolen. One of those attacked is a Catholic priest, who is singled out for sectarian abuse. Another tram is set on fire near Father Mathew‘s statue. Meanwhile, witnesses report seeing a group of 14–18 Black and Tans firing wildly for upwards of 20 minutes on nearby MacCurtain Street.

Soon after, witnesses report groups of armed men on and around St. Patrick’s Street, the city’s main shopping area. Most are uniformed or partially uniformed Auxiliaries and some are British soldiers, while others wear no uniforms. They are seen firing into the air, smashing shop windows and setting buildings on fire. Many report hearing bombs exploding. A group of Auxiliaries are seen throwing a bomb into the ground floor of the Munster Arcade, which houses both shops and flats. It explodes under the residential quarters while people are inside the building. They manage to escape unharmed but are detained by the Auxiliaries.

The Cork City Fire Brigade is informed of the fire at Dillon’s Cross shortly before 10:00 p.m. and are sent to deal with it at once. On finding that Grant’s department store on St. Patrick’s Street is ablaze, they decide to address it first. The fire brigade’s Superintendent, Alfred Hutson, calls Victoria Barracks and asks them to tackle the fire at Dillon’s Cross so that he can focus on the city centre. The barracks take no heed of his request. As he does not the resources to deal with all the fires at once, he has to prioritize the order in which the fires are addressed. He oversees the operation on St. Patrick’s Street and meets The Cork Examiner reporter Alan Ellis. He tells Ellis that “all the fires were being deliberately started by incendiary bombs, and in several cases, he had seen soldiers pouring cans of petrol into buildings and setting them alight.”

British forces hindered the firefighter’s attempts to tackle the blazes by intimidating them and cutting or driving over their hoses. Firemen are also shot at, and at least two are wounded by gunfire. Shortly after 3:00 a.m. on December 12, reporter Alan Ellis comes upon a unit of the fire brigade pinned down by gunfire near City Hall. The firemen say that they are being shot at by Black and Tans who have broken into the building. They also claim to see uniformed men carrying cans of petrol into the building from nearby Union Quay barracks.

At about 4:00 a.m. there is a large explosion and City Hall and the neighbouring Carnegie Library go up in flames, resulting in the loss of many of the city’s public records. According to Ellis, the Black and Tans had detonated high explosives inside City Hall. When more firefighters arrive, British forces shoot at them and refuse them access to water. The last act of arson takes place at about 6:00 a.m. when a group of policemen loot and burn the Murphy Brothers’ clothes shop on Washington Street.

After the ambush at Dillon’s Cross, IRA commander Seán O’Donoghue and volunteer James O’Mahony make their way to the farmhouse of the Delaney family at Dublin Hill on the northern outskirts of the city, not far from the ambush site. Brothers Cornelius and Jeremiah Delaney are members of F Company, 1st Battalion, 1st Cork Brigade IRA. O’Donoghue hides some grenades on the farm and the two men go their separate ways.

At about 2:00 a.m., at least eight armed men enter the house and go upstairs into the brothers’ bedroom. The brothers get up and stand at the bedside and are asked their names. When they answer, the gunmen open fire. Jeremiah is killed outright, and Cornelius dies of his wounds on December 18. Their elderly relative, William Dunlea, is wounded by gunfire. The brothers’ father says the gunmen wore long overcoats and spoke with English accents. It is thought that, while searching the ambush site, Auxiliaries had found a cap belonging to one of the volunteers and had used bloodhounds to follow the scent to the family’s home.

Over 40 business premises and 300 residential properties are destroyed, amounting to over five acres of the city. Over £3 million worth of damage (1920 value) is caused, although the value of property looted by British forces is not clear. Many people become homeless and 2,000 are left jobless. Fatalities include an Auxiliary killed by the IRA, two IRA volunteers killed by Auxiliaries, and a woman who dies from a heart attack when Auxiliaries burst into her house. Several people, including firefighters, are reportedly assaulted or otherwise wounded.

Irish nationalists call for an open and impartial inquiry. In the British House of Commons, Sir Hamar Greenwood, the Chief Secretary for Ireland, refuses the demand for such an inquiry. He denies that British forces had any involvement and suggests the IRA started the fires in the city centre.

Conservative Party leader Bonar Law says, “in the present condition of Ireland, we are much more likely to get an impartial inquiry in a military court than in any other.” Greenwood announces that a military inquiry would be carried out by General Peter Strickland. This results in the “Strickland Report,” but Cork Corporation instructs its employees and other corporate officials to take no part. The report blames members of the Auxiliaries’ K Company, based at Victoria Barracks. The Auxiliaries, it is claimed, burned the city centre in reprisal for the IRA attack at Dillon’s Cross. The British Government refuses to publish the report.
