We are thrilled to announce that An Irish Civil War Dugout: Tormore Cave, County Sligo. Archaeology, History, Memory, co-authored by Dr. Marion Dowd, Robert Mulraney, and Dr. James Bonsall, has been given the prestigious Literary Award at SUICRO 2024. This annual symposium, hosted by the Speleological Union of Ireland (SUI) and the Irish Cave Rescue Organisation (ICRO), recognizes outstanding contributions to cave exploration and archaeology.

The award is a testament to the groundbreaking nature of this new book, which presents the first archaeological excavation of a Civil War site in Ireland. The book, funded by ATU Sligo and the National Monuments Service, sheds light on the vital role of dugouts in guerrilla warfare during Ireland’s revolutionary period. The 420-page volume, published in hardback by Archaeopress and available as an open-access PDF, provides fresh insights into Tormore Cave, where over 30 anti-Treaty IRA men sought refuge in 1922 during the Irish Civil War.

Novel Ground in Cave Archaeology and Revolutionary History
An Irish Civil War Dugout covers uncharted territory in Irish history and cave exploration. By combining archaeology, military history, community memory, and landscape studies, the authors have created a highly detailed examination of a little-known aspect of guerrilla warfare. Tormore Cave, high in the mountains of County Sligo, provided a hidden sanctuary for IRA fighters during one of the most tumultuous periods in Irish history. Unlike most Civil War sites, Tormore Cave was never mentioned in official records, but its significance was preserved in local memory.
The excavation revealed nearly 200 artefacts, from pottery and glass to personal items and built structures, offering a rare glimpse into the daily lives of the men who hid in the cave. These artefacts, alongside local histories, paint a vivid portrait of hardship, resilience, and survival during a brutal conflict. The book goes beyond standard historical and archaeological narratives to tell a compelling story that appeals to both specialists and the general public.
A Story for Cavers and Historians Alike
One of the reasons this book stood out at SUICRO is its appeal to diverse audiences. Whether you’re a historian, caver, or someone interested in Ireland’s revolutionary history, An Irish Civil War Dugout offers something for everyone. Its detailed examination of geology, landscape, and human experience makes it an engaging read, while the interdisciplinary approach ensures that the book contributes to both cave archaeology and the broader understanding of Ireland’s past.
Award Presentation at SUICRO 2024
The award was presented on Sunday 27 October 2024 at SUICRO’s Caving Symposium in Doolin, Co. Clare. Each of the three authors—Dr. Marion Dowd, Robert Mulraney, and Dr. James Bonsall—received an individual framed certificate in recognition of their outstanding contribution to both cave studies and Irish history, with Robert Mulraney accepting the award on behalf of the research team.

Exploring Ireland’s Civil War through Archaeology
Tormore Cave, high in the mountains of County Sligo, served as a hidden sanctuary for anti-Treaty IRA fighters during one of the most tumultuous periods in Irish history. Combining archaeological excavations with local histories, this book delves into the Civil War dugout’s strategic role, uncovering its forgotten story a century later.
Historical Context
In September 1922, following a fierce firefight at Rahelly House in Sligo, more than 30 Republican fighters escaped into the mountains and took refuge in Tormore Cave. Unlike most Civil War dugouts, this site was never mentioned in official records. Yet, local memory preserved its significance, and on the centenary of the cave’s occupation, an archaeological excavation revealed the extensive modifications that transformed the natural cave into a habitable military hideout.
The excavation uncovered nearly 200 artefacts, including pottery, glass, personal items, and built structures that offer a window into the hardships endured by the men. Artefacts left behind provide a vivid portrait of daily life in the cave, while the stories of the men and women who supported them emerge from the shadows of history.
A Multidisciplinary Approach
This study, the first of its kind in an Irish context, facilitates a broader discussion on the role of dugouts in guerrilla warfare and highlights the lives of those who sought refuge in Tormore Cave. The book also features in-depth studies of key figures such as IRA General Officer Commanding Billy Pilkington, whose fascinating story has been largely overlooked in previous histories.
Contents Include
- Foreword by the National Monuments Service Chief Archaeologist Michael MacDonagh
- Archaeology of the cave, guerrilla warfare in Sligo, and historical context
- Artefacts and structures left behind in Tormore Cave
- Detailed appendices covering archaeological findings, geomorphology, pottery, bones, radiocarbon dates, and more

The People & Memory section of An Irish Civil War Dugout: Tormore Cave, County Sligo departs from the standard archaeological and historical narratives and brings to life the personal stories and struggles of those involved in and affected by the Civil War. Chapter 8 provides the most detailed biography of General Officer Commanding Billy Pilkington, a key yet often overlooked figure of the Irish Civil War. Pilkington’s leadership and resilience were pivotal during this turbulent period, as he skillfully balanced his role as commanding officer with a deep sense of responsibility for his men. He navigated the complexities of the conflict, striving to protect his comrades while avoiding the unnecessary loss of Irish lives – on both sides of the Civil War – whenever possible. After the war, true to a vow he made while in hiding at Tormore Cave, Pilkington became a Redemptorist Priest, dedicating his life to service and faith, further highlighting his remarkable character and commitment to others. Chapter 9 shifts focus to the IRA men billeted in Tormore Cave, exploring their day-to-day existence in the harsh conditions of the hideout. Chapter 10, sheds light on the crucial yet overlooked role of contributions of women as part of the IRA support infrastructure, as evidenced by civilian women, members of Cumann na mBan, and local Protestant families who vital to the success of the men in hiding. These women risked their lives to ensure the fighters were fed, cared for, and supplied with critical information and resources, underscoring their indispensable role in the conflict. Chapter 11 examines the aftermath and legacies of this turbulent time, considering the lasting impact on the individuals, families, and communities involved in this historical moment.
