Simon Egan (UCC): Enemies to the left, enemies to the right: The politics of the wider Gaelic world and the collapse of the MacDonald Lordship of the Isles, c.1460–1500
Francis Kelly (UCC): Brian O’Rourke and the Spanish Armada
Connie Kelleher (TCD): Ireland's golden age of pirates: Early seventeenth-century piracy in Southwest Munster in the Stuart period
James O’Neill (QUB): Half-moons and villainous work: Gaelic fortifications and the Nine Years war
Dr Benjamin Hazard (UCC): Combat medics and military medicine: Irish experience during the Tudor and Stuart period
A number of these will be worth listening to if you fancy wargaming Ireland in the 16th and 17th centuries. Listening to most of them might even make you a better, more well adjusted individual... ahem... but that's not something I can guarantee.
I must say that I haven't yet had a chance to listen to any of this years talks, but I thoroughly enjoyed last year's (including James O’Neill (QUB): Trailing pikes and turning kern: military acculturation in the Nine Years’ War) which are all still available as podcasts. Have a look at the programme here.
