The battle was fought in June 1346 and marked a minor turning point in the fortunes of the Montfortists and their English allies in Brittany following several setbacks including the imprisonment and subsequent death of their leader, John of Montfort.
His main opponent, Charles of Blois, was on the march with a substantial army of East Breton volunteers, French soldiers and German mercenaries, and a number of his allies and subordinates were showing signs of changing sides or declaring their independence from his command and setting up their own fiefdoms.
To strengthen his faction's morale, Dagworth was conducting a tour of his possessions on the Northern coast of Brittany,[1] thus confirming support in his rear and ensuring a valid line of retreat to England should his besieged strongholds in the south of the region fall.
He knew that cavalry would be doomed on the slopes of the hill and that the only way to break the English position and capture Dagworth before relief could arrive was a direct frontal assault with infantry.
The Anglo-Breton force had suffered lightly, and, despite a number of severe injuries, none of the knights or men-at-arms had been killed, while losses among the archers and rank and file were low, although actual totals were not recorded.
