In the Boer War of1899-1902Winburg was one of the Boer centres in the guerrilla fighting which followed the fall of Pretoria.
Guerrilla war (always successful, as history shows) directly infringes that rule.
From Campania the rebels marched into Lucania, a country better suited for guerrilla warfare.
The western border was rendered desolate and deserted by guerrilla forays throughout the war.
As it progressed the Germans adopted many of the methods employed by the British in their colonial wars, and they learned to appreciate more accurately the immensity of the task which Lord Kitchener accomplished in overcoming the guerrilla warfare in the Boer republics.
