half dried up by the summer’s heat[1281]--established his headquarters in the “borough of S. Martin” or Châteauneuf,[1282] and began to invest the city.[1283] Henry, it seems, had now gone to Saumur;[1284] there on the Sunday--July 2--he was visited, according to one account at his own request, by the archbishop of Reims, the count of Flanders and the duke of Burgundy, endeavouring to arrange terms of peace.[1285] The visit was a failure; it could not be otherwise, for the peacemakers were acting without Philip’s sanction, and in spite of a distinct warning from him that, whatever tidings they might bring back, he would assault Tours next morning.[1286] The morning came; the assault was made; the walls which had kept out Fulk Nerra and Geoffrey Martel could not avail to keep out Philip Augustus, enabled as he was by his possession of Châteauneuf and by the lack of water in the Loire to bring up his machines against their weakest side; and in a few hours he was master of Tours.[1287] [1273] Gir.

[1275] Some of Henry’s troops had thrown themselves into the citadel, and held out there for three days after his flight. _Gesta Hen._ as above. Another body of troops in a tower by the north gate (this must be the Conqueror’s Mont-Barbet--the “citadel” being the old palace or castle of the counts, near the cathedral) held out for a week longer still.

Diceto, as above, p. 64, makes the day June 28; Bishop Stubbs (_Rog. Howden_, vol. ii. pref. p. lxv) follows Gerald. [1278] Gir. Cambr. as above. [1279] Rog. Howden (Stubbs), vol. ii. pp. 365, 366, gives, with the date “circa festum apostolorum Petri et Pauli, ad colloquium inter Turonim et Azai,” a treaty identical with that which the _Gesta Hen._ as above, pp. 69, 70, give without any date at all, but after Philip’s capture of Tours, and which we know to have been finally made at Colombières on July 4 (see below, p. 265). R. Diceto (Stubbs), vol. ii. p. 63, also gives the substance of the treaty, adding (p. 64): “Facta sunt autem hæc in vigiliâ Apostolorum Petri et Pauli, scilicet inter Turonim et Azai.” It seems possible that the terms were arranged at Azay between Philip and Henry’s representatives, subject to ratification by Henry himself. See Stubbs, _Rog. Howden_, vol. ii. pref. p. lxv. [1280] On the date see Stubbs, _Rog. Howden_, vol. ii. pref. p. lxvi and note.
