But how then are we to account for the Chronicle of St. Brieuc’s very circumstantial statement of Conan’s defeat?--This chronicle--a late compilation--is our only authority for all the details of the war; for Guerech’s capture and homage, and in short for all matters specially relating to Nantes. The tone of all this part of it shews plainly that its compiler, or more likely the earlier writer whom he was here copying, was a violently patriotic man of Nantes, who hated the Rennes party and the Angevins about equally, and whose chief aim was to depreciate them both and exalt the house of Nantes in the person of Guerech. So great is his spite against the Angevins that he will not even allow them the credit of having slain Conan at the second battle of Conquereux, but says Conan fell in a fight with some rebel subjects of his own! He therefore still more naturally ignores the Angevin share in the first battle of Conquereux, and makes his hero Guerech into a triumphant victor. The cause of his hatred to Anjou is of course the mean trick whereby Geoffrey obtained Guerech’s homage. There can be little doubt that the battle was after this homage--was in fact caused by it; but the facts are quite enough to account for the Nantes writer putting, as he does, the battle first, before he brings the Angevins in at all, and giving all the glory to Guerech. 2. As to the Poitevin war. “Excussit Laudunum,” etc. (Fulk Rechin, Marchegay, _Comtes_, p. 376. See above, p. 137). The only other mention of this war is in the Chron. S. Maxent. (Marchegay, _Eglises_, p. 384), which says: “Eo tempore gravissimum bellum inter Willelmum ducem et Gofridum Andegavensem comitem peractum est. Sed Gaufridus, necessitatibus actus, Willelmo duci se subdidit seque in manibus præbuit, et ab eo Lausdunum castrum cum nonnullis aliis in Pictavensi pago beneficio accepit.” M. Mabille pronounces these two accounts incompatible; but are they? The Poitevin account, taken literally and alone, looks rather odd. William and Geoffrey fight; Geoffrey is “compelled by necessity” to make submission to William--but he is invested by his conqueror with Loudun and other fiefs. That is, the practical gain is on the side of the beaten party. On the other hand, Fulk Rechin, taken literally and alone, gives no hint of any submission on Geoffrey’s part. But why cannot the two accounts be made to supplement and correct each other, as in the case of the Breton war? The story would then stand thus: Geoffrey takes Loudun and defeats William at Les Roches, as Fulk says. Subsequent reverses compel him to agree to terms so far that he holds his conquests as fiefs of the count of Poitou. The case is nearly parallel to that of the Breton war; again the Angevin count and the hostile chronicler tell the story between them, each telling the half most agreeable to himself, and the two halves fit into a whole.
