The River War.

In vivid style the book describes the background to the war, the relationship of the Upper Nile to Egypt, the murder of General Charles George Gordon in the siege at Khartoum, the political reaction in England, and Kitchener's elaborate preparations for the war. While in the Sudan, Churchill participated in the Battle of Omdurman. Churchill comments at length on the mechanisation of war with use of the telegraph, railroad, and a new generation of weaponry.

The River War was Churchill's second published book after The Story of the Malakand Field Force and is one of the scarcer Churchill titles.
