A new assessment of Jan Smuts's military leadership through examination of his World War I campaigning, demonstrating that he was a gifted general, conversant with the craft of maneuver warfare, and a command style steeped in the experiences of his time as a Boer general. World War I ushered in a renewed scramble for Africa. At its helm, Jan Smuts grabbed the opportunity to realize his ambition of a Greater South Africa. He set his sights upon the vast German colonies of South-West Africa and East Africa - the demise of which would end the Kaiser's grandiose schemes for Mittelafrika. As part of his strategy to shift South Africa's borders inexorably northward, Smuts even cast an eye toward Portuguese and Belgian African possessions. Smuts, his abilities as a general much denigrated by both his contemporary and then later modern historians, was no armchair soldier. This cabinet minister and statesman donned a uniform and led his men into battle. He learned his soldiery craft under General Koos De la Rey's tutelage, and another soldier-statesman, General Louis Botha during the South African War 1899-1902. He emerged from that war, immersed in the Boer maneuver doctrine he devastatingly waged in the guerrilla phase of that conflict. His daring and epic invasion of the Cape at the head of his commando remains legendary.
