The Battle of Conquereuil was fought on 27 June 992 between the Bretons under Count Conan I of Rennes and the Angevins under Count Fulk III the Black of Anjou. The Bretons defended, and Conan carefully prepared the battlefield, digging pits and ditches which were flooded by the water of nearby swamps and then hidden by covering them lightly with sod, and behind this prepared earthworks which had their flanks secured by the swamps.
The Angevins attacked, and Breton troops lured the Angevin knights into the flooded pits by feigning flight. The Bretons then counterattacked and drove the Angevins back in disarray. During a lull in the battle, during which the Bretons apparently prematurely considered the battle won, Fulk reorganized his army, attacked the Bretons again, and routed them, killing Conan in the process.
Another version of the story suggests that the Breton counterattack was successful and drove the Angevins back in disarray. In the midst of a Breton pursuit, Conan removed his armour because it was hot, and some Angevin knights in a wood saw him, charged the unarmoured duke, and killed him, turning the battle decisively in the favor of the Angevins.
