On 27 July 1675 Anthony probably fought with George at Sasbach, where Turenne was killed. Two of Turenne's general officers considered themselves second in command: Count Guy Aldonce de Durfort de Lorges and the marquis de Vaubrun. At the retreat from Sasbach and the Battle of Altenheim in August the French army was therefore commanded by both until Vaubrun was killed in that battle on 1 August 1676. Finally arrived the new commander, Condé, whom the King had appointed. However, Condé was old and was soon replaced by Luxembourg. George was killed in June 1676 while commanding Luxembourg's rear-guard at the Zaberner Steige where imperial troops under Charles V, Duke of Lorraine pursued the French who were retreating eastward to Saverne in lower Alsace. Anthony succeeded to his brother's French title of "comte d'Hamilton". Voltaire calls him "comte" in his note of 1739. The Peace of Nijmegen of 1678 ended the Franco-Dutch War and Anthony seems to have returned to Ireland.
