In the third part, the focus shifts to the Boer guerrilla warfare and the British response. The advance to Komatipoort and De Wet's campaigns mark a turning point, showcasing the war's new dynamics. The second invasion of the Cape Colony and the northern operations further strain British resources, though they gradually gain the upper hand. Finally, the spring campaign of 1902 and De la Rey's battles bring the Boer resistance to an end. While the war concludes with the Boers' defeat and Britain's victory, it leaves deep scars on both sides, reflecting the devastating nature of the conflict.
