Three Accounts of the Glenmore Ambush

A Leaving Certificate student is preparing a research study on the Glenmore ambush of March 1921, in which an IRA flying column attacked a police patrol. She has three sources. Source A is a 14-page typed witness statement given in 1953 to the Bureau of Military History by the IRA company captain; it names the twelve volunteers present and describes a five-minute firefight. Source B is a one-page letter written in April 1921 by an RIC constable to his sister, saying 'about forty rebels' fired for 'a quarter of an hour'. Source C is an eight-page commemorative booklet produced in 1966 by a local committee; it gives no figure for the IRA party but says the patrol was 'annihilated'. The student also has a 1921 battalion roll that places two men named by the captain in a different county on the day. Her teacher warns her that the research study must discuss the reliability of sources, not simply narrate the ambush. She has two weeks and a 1,500-word limit.

1. Which source is most trustworthy for establishing the number of IRA volunteers who took part, and why? Refer to all three sources.

Read the worked answer

Start from provenance, not from the figure that looks most precise. The captain's 1953 statement is the only account by a named participant, and it lists twelve volunteers, but it was given 32 years later, when the Bureau was collecting pension-era testimony and when the captain had an interest in presenting a disciplined, successful operation. The constable's letter is contemporaneous and was written without knowledge that a historian would later read it, which is a strength; but 'about forty' is a hostile estimate made under fire and is not a count. The booklet is 45 years later, has a commemorative purpose, and gives no figure, so it cannot settle the point. The battalion roll is the closest to a contemporary administrative record, but it records posting, not necessarily physical presence; a man can be listed in another county and still have travelled. The defensible conclusion is not 'twelve' but 'a small party, probably ten to fifteen', with the captain's list as the starting point and the roll as a check. The student should say the exact number cannot be established from these sources alone.

2. Explain how the student should handle the contradiction between the captain's list and the battalion roll in her extended essay.

She should not conceal the contradiction or silently prefer the captain. First, set out the discrepancy precisely: two named men appear on the roll in another county. Second, ask what each source was for. The roll was compiled for battalion administration and may record permanent posting rather than the location on the day of the ambush; it may also be incomplete or copied later. The captain's statement was written to secure recognition and to shape the Bureau's record, so he had reason to name men who were there, but memory can also place a man at an event because he was associated with the unit. Third, look for independent checks: brigade operation reports, police records, later pension applications, local newspapers. In the essay, the discrepancy should become part of the argument about the difficulty of reconstructing a small ambush, not a footnote. A good conclusion would say the captain's list is probably broadly right but not proven in every name, and that the roll shows why a single witness statement cannot be treated as a roll-call.

3. The 1966 booklet says the patrol was 'annihilated'. How useful is this source for a historian studying the ambush?

Read the worked answer

Useful, but for a different question. As evidence of what happened militarily, it is weak: it is late, produced for a commemorative occasion, uses emotive language ('annihilated'), gives no numbers, and would have been shaped by the 50th-anniversary climate of 1966. It cannot establish casualties or the course of the fight. As evidence of memory and commemoration, it is valuable. The word 'annihilated' tells the historian how the event was remembered and claimed by the local community; the booklet's production by a local committee shows who controlled the story in 1966. The student should not quote it as a factual account of the ambush. She should ask: who wrote it, for whom, and what purpose did it serve? Used that way, it supports a paragraph on how independence-era events were commemorated, not a paragraph on troop numbers.
