I heard of a small group of Irish archaeologists who set up a military 'living history' group called Claiomh (Irish word for Sword), reenacting Late Medieval and Early Modern history. Personally this is my favourite period of Irish history.
If the lads from Claiomh happen to be members of our Shillelagh group and are reading this all I have to say is, well done on the great work. It is truly fascinating.
Here is a cut paste.
The group specialises in interpretations of warriors and soldiery c.1480-1660 A.D. of Irish Gaelic lineage (in which we include the galloglasses or gallóglaigh who were originally of Norse-Highland descent although who were by sixteenth-century times largely populated by native Irishmen), seasonal 'redshank' mercenaries from the Scots Highlands/Western Isles, those of Anglo-Irish - or 'Old English' - extraction, and Anglo-Scots Borderers. The period of speciality covered by Claíomh stretches from the last quarter of the fifteenth century with the final death throe of the Wars of the Roses at the Battle of Stoke Field in 1487 - which involved the invasion of England by a combined Hiberno-German force - carrying through to the epoch of the tumultuous sixteenth century under the shadow of the powerful Tudor dynasty, and onwards into the seventeenth century to the end of the Irish Confederate Wars fought in the 1640's.
