I found some of the bumph we put out at Trade Fairs and so on. Here's an excerpt.
Historical background by David Wilton
Justin MacCarthy, Lord Mountcashel commanded the Irish Brigade in the service of France.
The regiment was formed in 1683 from a number of Irish independent companies which were part of the English garrison of Tangiers. It served in the campaign of 1689 receiving heavy casualties at Newtownbutler. Later it was part of a body of troops exchanged for a number of French units which were sent to Ireland.
Straight into the field the Irish Brigade contributed to Marshal Catinat's victories in Savoy against the Piedmotese in 1690. Mountcashel's distinguished themselves in these Alpine campaigns. Then served in the French Army in Catalonia where it was present at the storming of fortresses along the Franco-Spanish borders. The regiment then went on to fight in Germany and was present at the capture of Heidelberg. Mountcashel died of wounds in this campaign and he was replaced by Andrew Lee, formerly Lieutenant-colonel of Clare's Irish Regiment. Before the end of the war in 1698 the regiment fought in Italy and the Low Countries.
