Answer
The Second Boer War, fought from 1899 to 1902, marked the first military engagement for Archibald Wavell, a prominent British general of World War II fame. This conflict, centered in South Africa, pitted the British Empire against the Boer republics of the Transvaal and Orange Free State. Wavell's participation in this early phase of his military career set the stage for his subsequent distinguished service and leadership in later campaigns.
