Renaud de Dammartin in the context of Count of Aumale

The Battle of Bouvines took place on 27 July 1214 near the town of Bouvines in the County of Flanders. It was the concluding battle of the Anglo-French War of 1213–1214. Although estimates on the number of troops vary considerably among modern historians, at Bouvines, a French army commanded by King Philip Augustus routed a larger allied army led by Holy Roman Emperor Otto IV in one of the rare pitched battles of the High Middle Ages and one of the most decisive medieval engagements.

In early 1214, a coalition was assembled against King Philip Augustus of France, consisting of Otto IV, King John of England, Count Ferrand of Flanders, Count Renaud of Boulogne, Duke Henry I of Brabant, Count William I of Holland, Duke Theobald I of Lorraine, and Duke Henry III of Limburg. Its objective was to reverse the conquests made by Philip earlier in his reign.
