But even at this time there was something dubious in the conduct of Menteth. While he retained the castle, the English held the town under Edward.
In peess thai duelt, in trubyll that had beyn,
And trewbut payit till Ingliss capdanis keyn.
Schir Jhon Menteth the castell had in hand:
Bot sum men said, thar was a prewa band
Till Sotheroun maid, be menys off that knycht,
In thar supple to be in all his mycht.—B. IX. 1393.
It is perfectly conceivable, that, although it was known to Wallace that Menteth had some secret understanding with the English, this artful man might persuade him that he only wished an opportunity of wreaking the national vengeance on them, or at least of more effectively serving the interest of Wallace when he saw the proper time. Although Wallace had been assured that Menteth had taken an oath of fealty to Edward, he would have had no more reason for distrusting him than for distrusting by far the greatest part of the nobility and landholders of Scotland, who, as they believed, from the necessity of despair had submitted to the usurper.
John de Menteth is designed by Arnold Blair immanis proditor; and the writer proceeds to curse him as if with bell, book, and candle. Relationes, p. 8.
Sir David aims another blow at this account in the following words: “That he had ever any intercourse of friendship or familiarity with Wallace, I have yet to learn.” But the truth is, the worthy judge does not seem disposed to learn this. It is difficult to say what evidence will satisfy him. The incidental hints, in the preceding part of the poem, in regard to Wallace’s connection with Menteth, all perfectly agree with the mournful termination. Such confidence had he in him, according to the Minstrel, that he not only resided in Dunbarton castle for two months, while Menteth had the charge of it, but gave orders for building “a house of stone” there, apparently that he might enjoy his society.
