Beginning with the disastrous Norwegian Campaign, it takes in the numerous attacks on the bustling German submarine base at Lorient, the attack on Brest, as well as many other pivotal and memorable events to enliven the history of the sea-lanes during the Second World War. Battles with the U-boats are brought to the fore, with details and experiences not only of the RAF pilots of Catalinas, Whitleys, Hudsons and Sunderlands, but also those of the targeted U-boat crews. In scenes reminiscent of 'Das Boot' German (and Italian) U-boat crews tell of their fears and experiences while under depth-charge attack and fire from above by Liberators, Fortresses, Halifaxes, Sunderlands and Mosquitoes. The 'big-game sport' of 'hunting U-boats', as it was termed, is relayed in full and gripping detail, with first-hand accounts from U-boat attackers punctuating Bowman's dramatic prose and resting alongside those of the German submariners. This two-sided history is sure to appeal to all enthusiasts interested in gaining a balanced insight into Second World War naval history.
