The Queen's became occupied by a succession of sieges: at Ghent, Bruges, and Lillie. In 1709, the regiment assisted in the protracted Siege of Tournai, which capitulated in September. On the 11th, the regiment fought in the bloodiest battle of the war: Malplaquet. After being committed from reserve in the battle's closing stages, the regiment advanced under heavy fire and fought through dense wood, having Lieutenant-Colonel Louis de Ramsay killed. The memoirs of Private Matthew Bishop, of the Queen's Regiment, contained an account that recalled: "the French were well prepared to give us a warm salute. It soon broke us in a terrible manner, though our vacancies were quickly filled up...when we got clear of the dead and wounded, we ran upon them and returning their fire, even broke them out of the breast-work."
