[1] Arthur Samuel Richardson, a British Army surgeon, died in 1816 aged 38 from a wound he received in the Officers' Mess in Dundalk Barracks.

His fatal wound was the result of a duel he had with a fellow officer who, allegedly, made a disparaging remark about a young woman of Richardson's acquaintance.

[5] The 28th Brigade Royal Field Artillery and D Squadron of the North Irish Horse were stationed in Dundalk just before the start of the Great War in 1914.

[11] The Irish Civil War began in June 1922 and on 16 July 1922 the pro-treaty 5th Northern Division led by Dan Hogan occupied Dundalk taking Aiken and his men prisoner.

Aiken organised boats to ferry his 300-strong force across the Castletown River into Dundalk and equipped two storming parties of ten men with submachine guns and explosives.

However, Patrick McKenna, a member of Aiken’s Division, had captured a Lancia armoured car from pro-Treaty troops elsewhere in Dundalk.

When he drove it through the main gate of the barracks after the fighting had ended, his comrades, mistaking it for a Free State counter-attack, detonated a mine, killing McKenna and another man Rogers.

[23] Second Lieutenant Collette McBarron, a former Miss Ireland contestant,[23] made the allegation against a fellow serving soldier which resulted in a full investigation by Irish Military Police.

[23] In the early hours of Monday 27 May 2013, an oil tanker containing illegal fuel which had been seized by the Irish Revenue Commissioners was stolen from Aiken Barracks and driven away.

[24] The tanker was one of a number of vehicles which had been part of a seizure at an illegal oil laundering plant in Drumacon, County Monaghan[24] and was subsequently stored at Aiken Barracks.

[24] Thieves breached the security of the base and made off in the lorry, which contained 20,000 litres of fuel valued at €30,000,[24] and which was then driven at high speed through the main gates of the Barracks (which were locked at the time).

[24] Soldiers who were on duty at the barracks' entrance were taken by surprise and the main gates sustained substantial damage as a result of the incident.
