In 1181, a conflict arose between Philip and Count [[Philip I of Flanders]] over the [[Vermandois]], which King Philip claimed as his wife's dowry. Finally the Count of Flanders invaded France, ravaging the whole district between the [[Somme (river)|Somme]] and the [[Oise]] before penetrating as far as [[Dammartin-en-Goële|Dammartin]]. Notified of Philip's approach with 2,000 knights, he headed back to Flanders.{{sfn|Bradbury|1997|p=245}} Philip chased him, and the two armies confronted each other near [[Amiens]]. By this stage, Philip had managed to counter the ambitions of the count by breaking his alliances with Duke [[Henry I of Brabant]] and the [[Electorate of Cologne|Archbishop of Cologne]], [[Philipp von Heinsberg]]. This, together with an uncertain outcome were he to engage the French in battle, forced the Count to conclude a peace. In July 1185, the Treaty of Boves left the disputed territory partitioned, with [[Amiens|Amiénois]], Artois, and numerous other places passing to the king, and the remainder, with the county of Vermandois proper, left provisionally to the Count of Flanders.{{sfn|Bradbury|1997|p=60}} It was during this time that Philip II was nicknamed "Augustus" by the monk [[Rigord]] for augmenting French lands.{{sfn|Baldwin|1991|p=3}}

Meanwhile, in 1184, [[Stephen I, Count of Sancerre]] and his [[Brabançons|Brabançon mercenaries]] ravaged the Orléanais. Philip defeated him with the aid of the [[Confrères de la Paix]].
