Brought together first as enemies in the Anglo-Boer War and later as allies in the First World War, the remarkable and often touching friendship between Winston Churchill and Jan Smuts is a rich study in contrasts.

In youth, they occupied very different worlds: Churchill, the rambunctious and thrusting young aristocrat; Smuts, the aesthetic, philosophical Cape farm boy who would go on to Cambridge. Both were men of exceptional talents and achievements, and between them the pair had to grapple with some of the 20th century's most intractable issues, not least of which was the task of restoring peace and prosperity to Europe after two of mankind's bloodiest wars.

Drawing on a maze of archival and secondary sources including letters, telegrams and the voluminous books written about both men, Richard Steyn presents a fascinating account of two remarkable men in war and peace: one the leader of the empire, the other the leader of a small fractious member of that empire who nevertheless rose to global prominence.
