The first book to explore in detail the wrecks of these two vessels from Force Z which in December 1941 was sent to defend Singapore. It grippingly narrates the lead up to the siege of Singapore and the battle far out at sea in which Force Z was decimated in the Royal Navy's greatest loss in a single engagement. The force was attacked by 85 Japanese torpedo bombers, with huge loss of life. It was the first time a modern battleship had been sunk by air power and the loss of Prince of Wales is seen as marking the end of the era of the battleship. The wrecks are explored in detail with illustrations of them on the seabed and underwater photographs.
