The significant battle in the Anglo-Zulu War that took place in 1879 was the Battle of Isandlwana. This battle, occurring on January 22, was notable for the British defeat at the hands of the Zulu warriors, who employed strategic and tactical advantages in the rugged terrain. The Zulu forces overwhelmed a well-armed British contingent, leading to over 1,300 British casualties, making it one of the worst defeats for the British army in colonial warfare. The shock of this defeat led to a renewed British campaign to subdue the Zulu Kingdom, ultimately resulting in their defeat at the Battle of Ulundi later that year.
