The Sowers of the Thunder is a short story by Robert E. Howard (published in Oriental Stories, Winter 1932) that takes place in Outremer (the Crusader states) in the time of General Baibars and deals with the General’s friendly/adversarial relationship with Cahal Ruadh O’Donnell, an Irish Crusader with a troubled past cut in the Howardian mold. Both the Siege of Jerusalem (1244) and the Battle of La Forbie feature in the plot.
