Note 206 — Chapter XIV · ACCESSION OF OMAR—REINFORCEMENTS FOR IRAC—CAMPAIGN THERE UNDER ABU OBEID AND MOTHANNA. Jumâd II., A.H. XIII.—Moharram, A.H. XIV. August, A.D. 634–March, A.D. 635.

Dates now begin to be given, but the chronology is still very doubtful. One authority places the battle forty days after that of Wacûsa on the Yermûk—that is to say, seven or eight weeks after Abu Bekr’s death. But in the interval between that event and the present battle, there took place Abu Obeid’s protracted march, the battle of Namârick and the expeditions following it, the gathering of Jabân’s army and its march, all which must have occupied at the least two months, and probably a good deal more.
