Note 154 — Chapter XI · CAMPAIGN IN SYRIA.—BATTLE OF WACUSA ON THE YERMUK. A.H. XIII. A.D. 634.
Reading edition
The strength of the four columns is usually given as 27,000, some authorities adding 3,000 rallied from Khâlid’s force, and some not. Tradition represents Abu Bekr as sending them forth each to reduce a given district in Syria—Abu Obeida, Hims; Yezîd, Damascus; Shorahbîl, the Jordan; Amru, Palestine. A palpable anticipation. Abu Bekr’s vision was yet bounded by the Roman army, and the issue doubtful.
