Hardback Although the Royal Navy did not invent the submarine, Norman Friedman’s new book demonstrates how innovative the service was, to an extent which few will recognise. Its submarines performed well in combat in both world wars, and often in unheralded ways. Few will be aware that in 1914 Britain had the largest submarine fleet in the world, and that at the end of World War I it had some of the largest and most unusual of all submarines – whose origins and design are all detailed. During the First World War they virtually closed the Baltic to German iron ore traffic, and they helped block supplies to the Turkish army fighting at Gallipoli. British submarines were a major element in the North Sea battles, and they helped fight the U-boat menace. These roles led on to British submarine operations in World War II.
