Churchill briefly rejoined the army as a lieutenant in the South African Light Horse regiment
In January 1900, Churchill briefly rejoined the army as a lieutenant in the South African Light Horse regiment, joining Redvers Buller's fight to relieve the Siege of Ladysmith and take Pretoria. He was among the first British troops in both places. He and his cousin, the 9th Duke of Marlborough, demanded and received the surrender of 52 Boer prison camp guards. Throughout the war, he had publicly chastised anti-Boer prejudices, calling for them to be treated with "generosity and tolerance", and after the war, he urged the British to be magnanimous in victory.
