The Beni Sakhr were fighting men; but we distrusted the Serahin. So Ali and I decided to make the Beni Sakhr, under Fahad, our storming party. We would leave some Serahin to guard the camels while the others carried the blasting gelatine in our dismounted charge upon the bridge. To suit the hurried carriage down steep hillsides in the dark we changed the explosive loads into thirty-pound lumps, which were put, for visibility, each lump into its own white bag. Wood undertook to repack the gelatine, and shared the rare headache all got from handling it. This helped pass the time.
