Kind Of Courage [PDF ebook] 

At the heart of this story of courage and might, is Major Billy Pentecost, commander of a remote desert outpost near Hahdhdhah, deep among the bleak hills of Khalit. His orders are to prepare to move out along with a handful of British soldiers. Impatient tribesmen gather outside the fort, eager to reclaim the land of their blood and commanded by Abd el Aziz el Beidawi, a feared Arab warrior lord. A friendship forms between the two very different commanders but when Pentecost’s orders are reversed, a nightmarish tragedy ensues.
