Book excerpt: First published in 1992. This book invites the reader to cast the mind a hundred and fifty years back to a short span of time between 1829 and 1842. This was an exciting period when Britain’s might, demonstrated to the world at Trafalgar and Waterloo, was fortified by leadership in steam technology and was given a new direction by the liberal philosophy that British statesmen, thinkers and poets proclaimed at home and abroad. The Euphrates expedition was an attempt by well-intentioned British governments to achieve a geopolitical end by a technological means. The objective was to halt Russian expansion in the Near East, where some observers saw a threat to Britain’s control of India.
