Note 168 — THE MINORITY OF HENRY III CHAPTER I THE WAR WITH LOUIS 1216–1217
Reading edition
Hist. G. le Mar., ll. 16240–46. Cf. R. Wend., l.c. In p. 25 Roger gives the date of the battle as “quarto decimo kalendas Junii, sabbato scilicet in hebdomada Pentecostes,” where the ecclesiastical date is correct, but not the civil one. One MS. of the Hist. Ducs makes it “la velle de la Pentecouste;” but the other has “la velle de la Trinite,” p. 194, note 3. The Annals of Waverley, a. 1217, give the true date, “tertio decimo kalendas Junii, in hebdomada Pentecostes.” So also R. Coggeshall, p. 185.
