The first armed conflict of the 20th century - the Anglo-Boer War of 1899-1902 - clearly demonstrated to the whole world the advent of a new generation of wars. The fruits of technological progress - automatic small arms, rapid-fire field artillery and armored trains - forced European military strategists to forget the axioms of the recent past. The war between the British and the Boers showed that relatively small military units, armed with modern weapons, with good marksmanship training and high morale, are capable of fighting on equal terms with superior enemy forces. During the Boer War, humanity also learned for the first time about scorched earth tactics, concentration camps, and war crimes. This book examines in detail the main events of the Anglo-Boer War, analyzes military-technical and tactical innovations that were first tested in the vastness of South Africa. The reader is given the opportunity to see the events of the war through the eyes of British and Boer commanders, to feel the intensity of long-past battles.
