Anti-Treaty Irish Republican Army (IRA) units carry out an ambush of Free State troops near Glenflesk, County Kerry, on August 27, 1922, as part of the broader Irish Civil War conflict between the pro-Treaty National Army and the anti-Treaty “Irregulars.”

By mid-August 1922, the Irish Free State, under Michael Collins, has launched a decisive offensive to re-take towns and strongholds in the south and west. The anti-Treaty IRA, led by figures such as Liam Lynch, has been holding areas like County Cork, County Limerick, and much of County Kerry, including Killarney, in defiance of the Anglo-Irish Treaty. The Free State’s campaign aims to consolidate control over the territory and end the conventional phase of the war.

The ambush at Glenflesk is one of several IRA actions in County Kerry during this period. It occurs as Free State forces advance in the west, seeking to secure supply lines and isolate remaining anti-Treaty strongholds. The Anti-Treaty IRA, using guerrilla tactics, targets convoys and patrols to disrupt Free State operations.

While the exact casualty figures for this specific engagement are not detailed in the available records, such ambushes are part of a wider pattern of republican resistance. In County Kerry alone, Free State forces suffer multiple engagements in August, including a sniper kill at Tralee and ambushes on supply columns.

The Glenflesk ambush reflects the shift from conventional warfare to mobile, hit-and-run tactics by the anti-Treaty IRA after the Free State’s conventional offensives begin. County Kerry remains a contested area, with Killarney and surrounding towns serving as republican bases. Ambushes like this one aim to delay Free State advances and protect supply routes. While the Free State’s overall campaign succeeds in capturing major towns by late August, such ambushes prolong the conflict and keep republican forces active until the “dump arms” order in 1923.

In summary, the Glenflesk ambush of August 27, 1922, is a localized but significant IRA resistance action in County Kerry, emblematic of the guerrilla warfare that follows the Free State’s conventional offensives and contributes to the prolonged nature of the Irish Civil War.
