Maghnus Ó Catháin
Manus O'Cahan's Regiment of Foot was an Irish regiment which served during the Wars of the Three Kingdoms in the mid-1640s.
Manus O'Cahan's Regiment of Foot was a body of soldiers, many of whom fought in Europe in the early years of the Thirty Years War. Historians such as C. V. Wedgwood refer to them as a 'Gallowglass' (i.e. mercenary) regiment. They were actually soldiers who sailed from Ireland to Scotland to fight for the Royalist cause there. Manus O'Cahan (Irish: Maghnus Ó Catháin) never set foot in England; all of his fighting took place in Ulster and Scotland. Their European combat experiences made them some of the most experienced soldiers serving in the Civil War.
Some of the men involved appear in a letter contained in the Ormond papers in the National Library of Ireland entitled "List of men gone unto the Isles. Sent by the Lord of Antrim to my Lord Ormonde, 15 Nov. 1644". The text reads:
