In the 19th century, advances in firearms technology rendered the use of close formations obsolete. The widespread use of rifled guns, such as cannons, and the advent of reliable breech-loading weapons and automated weapons, such as the Gatling gun, altered the tactical landscape. The new weapons fired at greater range with accuracy, and technological improvements in aiming them also simplified the targeting of large bodies of enemy forces. A major exception was in the Anglo-Zulu War after the Battle of Isandlwana. After that humiliating defeat, the British army found that close-order infantry formations were necessary to concentrate firepower to break the Zulu warriors' formidable massed charges.
