Seán South, a member of an Irish Republican Army (IRA) military column led by Sean Garland on a raid against a Royal Ulster Constabulary (RUC) barracks in Brookeborough, County Fermanagh, Northern Ireland, on January 1, 1957, dies of wounds sustained during the raid along with another IRA volunteer, Fergal O’Hanlon.

South is born in 1928 in Limerick where he is educated at Sexton Street Christian Brothers School, later working as a clerk in a local wood-importing company called McMahon’s. South is a member of a number of organisations including the Gaelic League, Legion of Mary, Clann na Poblachta, and Sinn Féin. In Limerick he founds the local branch of Maria Duce, a social Catholic organisation, where he also edits both An Gath and An Giolla. He receives military training as a lieutenant of the Irish army reserve, the LDF which later becomes the FCA (An Fórsa Cosanta Áitiúil or Local Defence Force), before he becomes a volunteer in the Irish Republican Army.

South is a devout Catholic, being a member of An Réalt, the Irish-speaking chapter of the Legion of Mary, and a conservative, even by the standards of the day. He is also a member of the Knights of Columbanus.

On New Year’s Day 1957, fourteen IRA volunteers cross the border into County Fermanagh to launch an attack on a joint RUC/B Specials barracks in Brookeborough. During the attack a number of volunteers are injured, two fatally. South and Fergal O’Hanlon die of their wounds as they are making their escape. They are carried into an old sandstone barn by their comrades which is later demolished by a British army jeep. Stone from the barn is used to build a memorial at the site.

The attack on the barracks inspires two popular rebel songs: “Seán South of Garryowen” and “The Patriot Game.” “Seán South of Garryowen,” is written by Sean Costelloe from County Limerick to the tune of another republican ballad “Roddy McCorley” and is made famous by The Wolfe Tones. The popularity of this song leads to the misconception that South is from Garryowen, a suburb in Limerick city. In fact, South is actually from 47 Henry Street in Limerick.

South is also mentioned in The Rubberbandits song “Up Da Ra”, which pokes fun at the concept of armchair republicanism using the literary device of the unreliable narrator.

There is a plaque dedicated to Seán South outside his birthplace on Henry Street, Limerick.
