Minor fighting with Britain began in the 1890s and in 1899 full-scale war ensued. By mid-June of 1900, British forces had captured most major Boer cities and formally annexed their territories, but the Boers launched a guerrilla war that frustrated the British occupiers. Beginning in 1901, the British began a strategy of systematically searching out and destroying these guerrilla units, while herding the families of the Boer soldiers into concentration camps. By 1902, the British had crushed the Boer resistance, and on May 31 of that year, the Peace of Vereeniging was signed, ending hostilities.
