The Frank writers give no precise date for the advance of the host in 1191 from “between the two Casals” to the neighbourhood of Ramlah. Ambrose says they reached the former position on the eve of All Saints, and stayed there “full fifteen days or more” (_Est._, ll. 7199-209). The _Itin._, 289-90, agrees with him. This should mean that they set out again on November 15 or 16. Ambrose, according to the printed text of the _Estoire_, says the journey to the next encampment took two days: “L’ost erra par mi la plaine, Sor les biaus chevals peus d’orge; _Vint en deus jors_ entre Seint Jorge e Rames; la s’allerent tendre Por plus gent e vitaille atendre” (ll. 7464-8). Thus they would arrive there—_i. e._ between Lydda and Ramlah—on November 17 or 18. The poet further says that the weather afterwards compelled them to take shelter within the two towns, “e fumes la bien sis semaines” (ll. 7471-7; _Itin._, 298-9, says the same). We presently find that they made their next advance—to Beit Nuba—on January 3. Thus we arrive at November 22 as the date of entering Lydda and Ramlah, and the encampment “in the plain” appears to have lasted five or six days (November 17 or 18-22). Our best Arab authority, Bohadin, unluckily does not mention the matter. Ibn Alathyr (_Rec. Hist. Or._, II. i. 54) says “the Franks set out from their camp at Jaffa for Ramlah on 3 Dulkaada” = November 22; the same date is given for their “advance in the direction of Ramlah” by Abu Shama (_ib._, v. 48), but without any clue to his authority for the statement. Ibn Alathyr gives this same date, 3 Dulkaada, as that on which “the Franks advanced from Ramlah to Natroun” (_l.c._); this is doubtless a confusion, made either by author or scribe, between “Dulkaada” and “Dulheggia,” as Richard—though, indeed, not the host—did remove to Natroun on December 22 or 23 (= 3 or 4 Dulheggia). The Frankish and the Arab authorities may be partially reconciled by taking the “six weeks” of Ambrose and the _Itinerarium_ as covering the whole period spent not only within the towns, but also “between” them. In that case, however, the stay between the two Casals must have been more than fifteen days; it could not have been less than twenty days, indeed twenty-two seems a more reasonable reckoning, for it is hard to see how two days can possibly have been spent in marching even from Casal of the Plains (the more remote of these two Casals) to either Lydda or Ramlah, a distance of less than eight miles. One writer does expressly mention “twenty-two days” in his account of this part of the Crusade; but he does so in connexion with the sojourn, not between the Casals, but between Lydda and Ramlah. Ambrose’s lines, 7464-8, quoted above, are in the _Itinerarium_ (298) represented as follows: “Exercitus noster fixis tentoriis _inter S. Georgium et Ramulam sedit viginti et duobus_ diebus, ut gentem expectaret venturam et annonam.”
