Battle of Yarmuk
“A gorge north of the Yarmuk River, August 636. Khalid ibn al-Walid's Arab cavalry sweeps the Byzantine flank into the ravine. Foreground shows mailed Ghassanid horsemen broken in flight; midground reveals dust storms blown by the south wind blinding Heraclius' Greeks; the Golan basalt cliffs drop into a gorge filled with falling banners.”
