[438] Will. Jumièges, l. vii. c. 18 (Duchesne, _Hist. Norm. Scriptt._, p. 276); _Gesta Cons._ (as above), pp. 121, 122; the details of the treaty are in pp. 123, 124. [439] _Gesta Amb. Domin._ as above. The acquisition of Tours closes the second stage in the career of the house of Anjou. Looked at from a strictly Angevin point of view, the period just passed through, although in one sense only preliminary, is the most important of all, for it is that on which depended all the later growth, nay, almost the very existence of Anjou. Had the counts of Blois proved too strong for her in these her early years, she would have been swallowed up altogether; had they merely proved themselves her equals, the two states so closely bound together would have neutralized each other so that neither of them could have risen to any commanding eminence; till one or the other should sweep its rival out of its path, both must be impeded in their developement. At the opening of the struggle, in Fulk Nerra’s youth, Blois was distinctly in the ascendant, and the chances of independent existence for the little Marchland hung solely on the courage and statesmanship of its count. His dauntless genius, helped by Odo’s folly, saved Anjou and turned the tide completely in its favour. The treaty sworn, four years after Fulk’s death, in his great castle by the Indre, was the crowning of his life’s work, and left his son absolutely without a rival till he chose to seek one beyond the debateable ground of Maine. The long struggle of Fulk and Odo, completed by Geoffrey and Theobald, had made a clear field for the future struggles of Geoffrey and William, of Fulk V. and Henry I., and at last--by a strange turn of fate--for a renewal of the old feud with the house of Blois itself, in a new form and for a far higher stake, in the struggle of Stephen and Henry Fitz-Empress for the English crown. NOTE A. THE SIEGE OF MELUN. The fullest account of this Melun affair is in Richer, l. iv. cc. 74–78. Briefly, it comes to this: Odo (described simply by his name, without title of any kind) “rerum suarum augmentum querebat,” and especially the castle of Melun, partly for the convenience of getting troops across the Seine, and partly because it had formerly belonged to his grandfather and was now in the hands, not of the king, but of “another” (not named). He managed to corrupt the officer in command and to obtain possession of the place. As soon as the kings (_reges_) heard of it, they gathered their forces to besiege him there: “et quia castrum circumfluente Sequanâ ambiebatur, ipsi in litore primo castra disponunt; in ulteriore, accitas piratarum acies ordinant.” These “pirates” furnished a fleet which blockaded the place, and finally discovered a secret entrance whereby they got into the town, surprised the castle, and compelled it to surrender to the king (_regi_).
