Battle of Fontenoy

The Battle of Fontenoy (25 June 841), also called the Battle of Fontenoy-en-Puisaye or Battle of Fontenay in older works, was the largest battle of the Carolingian civil war. Fought at Fontenoy in the Puisaye, the battle was a major defeat for the allied forces of Lothair I of Italy and Pepin II of Aquitaine, and a victory for Charles the Bald and Louis the German. It was not, however, decisive.
