A World On Fire: An Epic History of Two Nations Divided

 
From the publishers:
During the titanic struggle between North and South, both sides demanded Britain's support. British volunteers fought on both sides; British guns and bullets littered the battlefields. The South depended on British-built cruisers to make up its navy, and British blockade runners to supply its armies.
 
This book portrays the extraordinary web of relationships between the two countries through the lives of over a hundred participants – soldiers, mercenaries, politicians, spies, journalists, diplomats, doctors and nurses who, at home or abroad, recorded their experience of the war. Some of these directly affected the momentous events around them, others were simply acted upon. It traces the often desperate efforts of men and women to survive, to preserve the ideals and ways of living they believed were right, and even, sometimes, to find love in the worst of circumstances.
 
A World On Fire is history told in the round, combining the human intensity of battle with the manoeuvrings of fraught diplomacy. The well-known events of the war are seen through fresh eyes: the letters of soldiers fighting thousands of miles from their homeland; the passionate dispatches from diplomats and journalists; and the diaries of the brave women who laboured in some cases to save a single life, and in others to protect an entire way of life.
