Cause

During the Anglo-Boer War, Boer forces in the Transvaal shifted away from conventional set-piece battles toward guerrilla tactics as British forces advanced. In the area between Pretoria and Rustenburg, Boer commander Koos de la Rey organized irregular forces to exploit terrain and surprise, capitalizing on British vulnerabilities in dispersed operations.

Event

On 11 July 1900, Boer guerrillas under Koos de la Rey surprised British troops at the Silkaatsnek mountain pass using a new guerrilla approach rather than a conventional engagement. The same day, British forces suffered two additional reverses at the Battle of Dwarsvlei in the Krugersdorp district and at Onderstepoort, indicating a broader pattern of coordinated Boer pressure.

Consequence

The engagement highlighted the growing effectiveness of Boer guerrilla methods against British troops and foreshadowed the prolonged irregular warfare phase of the Anglo-Boer War. A few days later, on 16 July 1900, British forces managed to withstand a Boer attack at the Battle of Witpoort east of Pretoria, showing the conflict remained fiercely contested.
