The collection consists of manuscript and typescript biographical accounts of Volunteers and civilians who died during the War of Independence and Civil War and who had links with the West Clare Brigade IRA. The accounts provide detailed information concerning the birth, early education and military career of each individual.

The collection illuminates a turbulent period in Irish history stretching from the later decades of the nineteenth century until the end of the Civil War in 1923. The inclusion of biographical details of Volunteers who were killed during the Civil War while fighting on the anti-Treaty side makes it historically significant, as information of this nature was rarely recorded.

The collection comprises primarily correspondence between Frank Aiken, IRA Chief of Staff; Mr McAuliffe Acting Officer Commanding Limerick Brigade IRA; and Maurice Twomey Inspecting Officer. They are almost solely concerned with the reorganisation of the IRA command structure in Limerick, Clare and Kerry owing to the shortage of men and equipment during and following the Civil War.
