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.

The western border was rendered desolate and deserted by guerrilla forays throughout the war.
