It is remarkable that Pedro was very popular with his own party, despite his crimes, and Chaucer takes his part because our Black Prince fought on the side of Pedro against Enrique at the battle of Najera, April 3, 1367; and because John of Gaunt married Constance, daughter of Pedro, about Michaelmas, 1371.
3573. See the description of Du Gueschlin's arms as given below. The 'field' was argent, and the black eagle appears as if caught by a rod covered with birdlime, because the bend dexter across the shield seems to restrain him from flying away. The first three lines of the stanza refer to Bertrand Du Gueschlin, who 'brew,' i. e. contrived Pedro's murder, viz. by luring him to Enrique's tent. But the last three lines refer to another knight who, according to Chaucer, took a still more active part in the matter, being a worker in it. This second person was a certain Sir Oliver Mauny, whose name Chaucer conceals under the synonym of wicked nest, standing for O. Fr. mau ni, where
mau is O. Fr. for mal, bad or wicked, and ni is O. Fr. for nid, Lat. nidus, a nest. Observe too, that Chaucer uses the word need, not deed. There may be an excellent reason for this; for, in the course of the struggle between the brothers, Enrique was at first thrown, 'when (says Lockhart) one of Henry's followers, seizing Don Pedro by the leg, turned him over, and his master, thus at length gaining the upper hand, instantly stabbed the king to the heart. Froissart calls this man the Vicomte de Roquebetyn, and others the Bastard of Anisse.' I have no doubt that Chaucer means to tell us that the helper in Enrique's need was no other than Mauny. He goes on to say that this Mauny was not like Charles the Great's Oliver, an honourable peer, but an Oliver of Armorica, a man like Charles's Ganelon, the well-known traitor, of whom Chaucer elsewhere says (Book of the Duchess, l. 1121)—
'Or the false Genelon,
He that purchased the treson
Of Rowland and of Olivere.'
This passage has long been a puzzle, but was first cleared up in an excellent letter by Mr. Furnivall in Notes and Queries, which I here subjoin; I may give myself the credit, however, of identifying 'wicked nest' with O. Fr. mau ni.
'The first two lines [of the stanza] describe the arms of Bertrand du Guesclin, which were, a black double-headed eagle displayed on a silver shield, with a red band across the whole, from left to right [in heraldic language, a bend dexter, gules]—"the lymrod coloured as the glede" or live coal—as may be seen in Anselme's Histoire Généalogique de France, and a MS. Généalogies de France in the British Museum. Next, if we turn to Mr. D. F. Jamison's excellent Life and Times of Bertrand du Guesclin, we not only find on its cover Bertrand's arms as above described, but also at vol. ii. pp. 92-4, an account of the plot and murder to which Chaucer alludes, and an identification of his traitorous or "Genylon" Oliver, with Sir Oliver de Mauny of Brittany (or Armorica), Bertrand's cousin [or, according to Froissart, cap. 245, his nephew].
'After the battle of Monteil, on March 14, 1369, Pedro was besieged in the castle of Monteil near the borders of La Mancha, by his brother Enrique; who was helped by Du Guesclin and many French knights. Finding escape impossible, Pedro sent Men Rodriguez secretly to Du Guesclin with an offer of many towns and 200,000 gold doubloons if he would desert Enrique and reinstate Pedro. Du Guesclin refused the offer, and "the next day related to his friends and kinsmen in the camp, and especially to his cousin, Sir Oliver de Mauny, what had taken place." He asked them if he should tell Enrique; they all said yes: so he told the king. Thereupon Enrique promised Bertrand the same reward that Pedro had offered him, but asked him also to assure Men Rodriguez of Pedro's safety if he would come to his (Du Guesclin's) lodge. Relying on Bertrand's assurance, Pedro came to him on
March 23; Enrique entered the lodge directly afterwards, and after a struggle, stabbed Pedro, and seized his kingdom.
