The Battle of Bussaco was fought on 27 September 1810. The night before, Fririon recommended that the Anglo-Portuguese army of Arthur Wellesley, Viscount Wellington be flanked out of position instead of assaulted directly. Masséna dismissed this idea, saying, "You are of the Army of the Rhine, you like to maneuver; this is the first time that Wellington appears disposed to offer battle. I will profit by the occasion". The attack was a failure with the French suffering 4,479 killed, wounded or captured against only 1,252 Allied casualties. While the French army was before the Lines of Torres Vedras, Fririon urged that the VIII Corps be withdrawn from its exposed position at the village of Sobral. During Masséna's tenure in command the Battle of Fuentes de Onoro would be fought on 3–5 May 1811.
