Lille raised a Poitevin army to besiege Lusignan Castle held by an Anglo-Gascon garrison in Summer 1349.
He attacked an Anglo-Gason force of 500 mounted men, led by Thomas Coke, Seneschal of Gascony while they were on their way to relieve Lusignan.
[4] The third Poitevin battle did not attack, holding its position waiting for any opportunity to exploit any weaknesses in the Anglo-Gascon lines.
When none had arisen by nightfall the third Poitevin battle retreated back to Lusignan with the captured horses.
In the course of the fighting, 300 Poitevins were killed and many were captured, including Lille and Jean de Boucicault.
