The war for the British life-line of the English Channel Throughout history the English Channel has both preserved Britain and been its most vulnerable border. This short span of sea was dominated by the Royal Navy for over 150 years before the outbreak of the Great War. A new war-the first major conflict of the technological age-brought new dangers and challenges. A constant traffic of men and materials crossed the Channel to serve and supply the armies locked in a death struggle on the continent and this vital artery had to remain open and effective at all times to ensure victory and survival. Enemy submarines, surface flotillas and batteries of artillery remained dangerously close at hand, and well defended ports and harbours provided a continual threat to allied traffic and forces. This is the story of a fierce naval war fought in a narrow sea-way by one who experienced it. It is a story of naval battles and daring raids, of the bombing arm of the emergent air force and of the submarine service at its most daring. Above all it is a riveting story of human courage and endurance that will fascinate every student of the First World War.
