Admiral Lord West begins his history of the Royal Navy in the twentieth century, covering the period from 1900 to 1939.
In this first week's omnibus, Lord West describes how the extraordinary technical, social and geo-political change of the first four decades of the century affected, and in turn were affected by, the Navy.
It was a period in which decisions about the Navy had a dramatic impact not just on Britain, but the rest of the world. Lord West describes the Navy's key role in how Turkey entered the First World War, explores how the Navy's switch from coal to oil altered the course of the entire twentieth century, and reveals the Navy's vital role in winning the First World War.
