Sir Walter Manny, in spite of the inferiority of his force, sallied out to relieve it, but it was taken before his arrival, and Don Louis had marched away to Dinan, leaving a small garrison in Conquet.

It was again captured by Sir Walter, but finding it indefensible he returned with the whole of his force to Hennebon.

Don Louis captured Dinan and then besieged Guerande.

Here he met with a vigorous resistance, but carried it by storm, and gave it up to be pillaged by his soldiers.

He now sent back to Charles of Blois the greater part of the French troops who accompanied him, and embarked with the Genoese and Spanish, 8000 in number, and sailed to Quimperle, a rich and populous town in Lower Brittany.
Anchoring in the River Leita, he disembarked his troops, and leaving a guard to protect the vessels marched to the interior, plundering and burning, and from time to time despatching his booty to swell the immense mass which he had brought in his ships from the sack of Guerande.
Quimperle lies but a short distance from Hennebon, and Sir Walter Manny with Almeric de Clisson, a number of English knights, and a body of English archers, in all three thousand men, embarked in the ships in the port, and entering the Leita captured the enemy's fleet and all his treasure.
