Charles Royle, The Egyptian campaigns, 1882 to 1885
“ Suddenly from the bush all along the face of the zeriba fronting Tamaai burst out a clamour of savage cries, and the next instant the whole assemblage of transport animals plunged forward. There was a multitude of roaring camels, apparently heaped one upon another, with strings of kicking and screaming mules, entangled in one moving mass. Crowds of camp-followers were carried along by the huge animal wave, crying, shouting, and fighting. All these surged up on the zeriba, any resistance being utterly hopeless. ”
