Tarzan the Untamed Book 7, The Original Novel

Hauptmann Fritz Schneider trudged wearily through the somber aisles of the dark forest. Sweat rolled down his bullet head and stood upon his heavy jowls and bull neck. His lieutenant marched beside him while Underlieutenant von Goss brought up the rear, following with a handful of askaris the tired and all but exhausted porters whom the black soldiers, following the example of their white officer, encouraged with the sharp points of bayonets and the metal-shod butts of rifles.
There were no porters within reach of Hauptmann Schneider so he vented his Prussian spleen upon the askaris nearest at hand, yet with greater circumspection since these men bore loaded rifles—and the three white men were alone with them in the heart of Africa.
Ahead of the hauptmann marched half his company, behind him the other half—thus were the dangers of the savage jungle minimized for the German captain. At the forefront of the column staggered two naked savages fastened to each other by a neck chain. These were the native guides impressed into the service of Kultur and upon their poor, bruised bodies Kultur's brand was revealed in divers cruel wounds and bruises.
