The largest fleet the Royal Navy committed to any operation of the western war was assembled to escort fourteen fast merchantmen across a thousand of miles of sea defended by six hundred German and Italian aircraft, together with packs of U-boats and torpedo craft. The Mediterranean battles that ensued between 11 and 15 August were the most brutal of Britain's war at sea, embracing four aircraft-carriers, two battleships, seven cruisers, scores of destroyers and smaller craft. The losses were appalling: defeat seemed to beckon.This is the saga Max Hastings unfolds in his first full length narrative of the Royal Navy, which he believes was the most successful of Britain's wartime services. As always, he blends the 'big picture' of statesmen and admirals with human stories of German U-boat men, Italian torpedo-plane crews, Hurricane pilots, destroyer and merchant-ship captains, ordinary but extraordinary seamen.
