Events of 1211.
The Meridional forces (under Count of Toulouse
and his allies the Count of Foix and Savaric de Mauléon)
were besieging Castelnaudary where Simon de Montfort and his French
Crusader army were holed up. The meridional's encampment was strong
but did not entirely surround the walls of the town.
Following the advice of Hugues de Lacy, Simon sent some knights,
among them Guy de Lévis and Bouchard de Marly, to seek as
many reinforcements as possible. Martin d'Algai and his mercenaries
rode to reinforce them, but the Count of Foix planned to ambush
them near the castle of Saint-Martin, 3 miles from Castelnaudary.
Simon got wind of this and sent Guy de Lucy, Simon de Neauphle,
Roard de Donges and 40 other knights to their rescue.
The Count of Foix returned to Castelnaudary bringing more troops
which, when the battle started, he organised in 3 battallions (heavy
cavalry at the centre, lighter cavalry on one wing, infantry on
the other). It appears that the Count of Foix acted on his own,
without support from the other lords.
Outnumbered, Martin d'Algai's mercenaries fled, which incited some
of Foix's troops to plunder the baggage train and leave the battlefield
while the fierce cavalry battle continued.
Simon, who had seen this, dashed out of Castelnaudary with 60 knights
leaving only 5 knights and the infantry to defend the castle against
de Mauléon's attacks.
Now the Count of Foix was in danger and his troops fled in disarray.
Severe losses had been inflicted on both sides.
The following day, Simon left Castelnaudary, leaving only a small
A few days later, the Meridionals raised the siege.
Both sides claimed victory.
