In June 1905, a special tour was organized by R. Barry O'Brien and the Irish Literary Society (he was chairman of I.L.S.) in Tournai and Fontenoy and promoted this idea of a memorial which was accepted with enthusiasm by the whole society.

Two years later, in 1907, the Irish memorial, called "The Irish Cross of Fontenoy" was erected in the centre of Fontenoy, near the church.  The inscription at the base, in Gaelic and French, commemorating the gift of the Irish people and the courage of the Irish Brigade.

R. Barry O'Brien was really the Irish promoter of this famous Irish memorial dedicated to the courage of the Irish Brigade in Fontenoy

Some other informations about wounded officers at Fontenoy:
In the original list of the French army' s losses at the battle of Fontenoy (11th May 1745), I quoted four wounded officers named O'Brien: 3 in Clare regiment and 1 in Rooth regiment:

1. O'Brien (Bernard) : régiment de Clare, capitaine, blessé à la tête
                                                                       (injured at the head)
2. O'Brien (Bernard) : régiment de Clare, lieutenant, blessé au ventre
                                                                     (injured at the stomach)
3. O'Brien (Charles) : régiment de Clare, lieutenant, blessé à l'épaule
                                                                     (injured at the shoulder)
4. O'Brien : régiment de Rooth, capitaine, une contusion au bras
                                                              (contusion at the arm)
(document: official list of French army, 1745)

The Irish brigade to the service of the King of France was composed of six different regiments and led a courageous fight against the troops of William Augustus, Duke of Cumberland; this brigade conquered the only British flag captured by the French army. (Fontenoy, 11th May 1745).
