Charles O'Brien, 5th Viscount Clare

[1] The family fought as part of the Jacobite Irish Army during the War of the Two Kings, before going into exile in the Flight of the Wild Geese.

[2] Charles was transferred from the Queen's Dismounted Dragoons where he was colonel, to the command of O'Brien's Regiment on 6 April 1696.

Many became beggars but others joined the Irish Brigade in the Spanish army, while others went to Austria and entered the Catholic Corps.

At the Battle of Cremona, in 1702, the Irishmen defended the town against Prince Eugene and the imperial army.

Two months after Blenheim, Charles rose to the brevet rank of Marshal-de-Camp on 26 October 1704, and a year later Lord Clare was assigned to the Army of the Moselle under the Marshel de Villars.
