Marico Commando Operations (1900–1902)
The Marico Commando (comprising burghers primarily from the Zeerust area) underwent a massive transformation during the war, shifting from conventional siege tactics to elite guerrilla warfare under General Koos de la Rey: [1, 2, 3]

- Early War (1899–1900): Under General J.P. "Kootjie" Snyman, the commando initially operated along the Bechuanaland border, disabling British rail lines and spearheading the long Siege of Mafeking. [1, 2, 3]
- The Shift to Guerrilla Tactics (Late 1900): After conventional Boer capitals fell, the Marico Commando abandoned their heavy wagons to become a highly agile, horse-mounted strike unit. They survived by capturing British supply columns, using the enemy's own rifles and ammunition. [1]
- The Scorched Earth Resistance (1901–1902): By the time Kaptein Gronum was commanding his unit, the British had burned down most homesteads in the Marico district and gathered civilian families into concentration camps. Operating in hidden bushveld pockets, the Marico Commando joined forces with the Lichtenburg and Rustenburg commandos to launch devastating hit-and-run ambushes. [1, 2]
The Battle of Ysterspruit (25 February 1902)
Kaptein Gronum lost his life in one of the most brilliant tactical victories achieved by the Boer forces during the entire war: [1]
- The Target: A heavily armed British convoy consisting of 150 wagons, half a million rounds of ammunition, and a large treasury of money moving near Klerksdorp.
- The Tactic: General de la Rey deployed the commandos to charge blindly on horseback through thick dust while firing from the saddle—a terrifying tactic that completely broke the British lines.
- The Outcome: The Boers captured the entire convoy, securing desperately needed supplies just months before the war ended. However, Kaptein Gronum was among the few Boer casualties killed during the heavy crossfire. [1, 2]
