"Shaka used impis with a modified encircling tactic - impondo zankoma ('bull's horns'); Impi troops would divide into four groups. The main group (isifuba, 'chest') would face the enemy, two wings (izimpondo, 'horns') on two sides of the enemy and then force them towards the center. The fourth party (usually the veterans) remained as a reserve. They travelled light, and carried their own food or foraged along the way. The image of the Zulu warrior who could "run fifty miles and fight a battle at the end of it" is not at all true, but the barefooted Zulu warrior was swift, and could cover perhaps 25 miles a day. Thus tactics against their enemies (other African tribes, the Boers, and the British) were surprise and overwhelming force, rather than siege or long campaigns. During the Anglo-Zulu War, British commander Lord Chelmsford complained that they did not 'fight fair'."
