Over the last 30 years, hydrographical marine surveys in the English Channel helped uncover the potential wreck sites of German submarines, or U-boats, sunk during the conflicts of World War I and World War II. Through a series of systemic dives, nautical archaeologist and historian Innes McCartney surveyed and recorded these wrecks, discovering that the distribution and number of wrecks conflicted with the published histories of U-boat losses. Of all the U-boat war losses in the Channel, McCartney found that some 41% were heretofore unaccounted for in the historical literature of World War I and World War II. This book reconciles these inaccuracies with the archaeological record by presenting case studies of a number of dives conducted in the English Channel. Using empirical evidence, this book investigates possible reasons historical inconsistencies persist and what Allied operational and intelligence-based processes caused them to occur in the first place. This book will be of interest to scholars and researchers in the fields of nautical archaeology and naval history, as well as wreck explorers.

Marine archaeologist Dr Innes McCartney solves the mysterious fate of the lost ships of Jutland and reveals – for the first time – the location and state of the wrecks of all 25 warships sunk in the scuttling of the German fleet at Scapa Flow.

The German High Seas Fleet was one of the most power naval forces in the world, and had fought the pride of the Royal Navy to a stalemate at the battle of Jutland in 1916. After the armistice was signed, ending fighting in World War I, it surrendered to the British and was interned in Scapa Flow pending the outcome of the Treaty of Versailles. In June 1919 the entire fleet attempted to sink itself in the Flow to prevent it being broken up as war prizes. Of the 74 ships present, 52 sunk and 22 were prevented from doing so by circumstance and British intervention.

Marine archaeologist and historian Dr Innes McCartney reveals for the first time what became of the warships that were scuttled, examining the circumstances behind the loss of each ship and reconciling what was known at the time to what the archaeology is revealing today. This fascinating study reveals a fleet lost for nearly a century beneath the waves..

The submarine was as formidable a weapon for the Royal Navy in World War II as for the other main combatant nations. The first half of this book explores the conception, design, development and subesequent evolution of the three major classes: the "S," "T," and "U."
The "S" Class submarine was originally conceived in the 1920s, specifically for deployment in narrow seas. As the war progressed the submarine was modified to increase its diving capability and fuel-carrying capacity, and radar and many other features were added. The "S" Class served in all theaters from the North Atlantic to the Pacific with notable success, in many cases surviving very severe damage.
The "T" Class submarine was originally conceived for operations in the Far East, thus was one of the largest types to be built and serve in World War II. The development of the "T" Class during the war was sometimes at the expense of its underwater stability and in the Mediterranean theater half of the submarines that were deployed sunk.
The "U" Class include "Upholder," the most successful British submarine of World War II.
The second half of the book surveys the major submarine actions of the war, including the Norwegian Campaign, operatins to save Malta and many other engagements in all theaters involving British submarines, German U-Boats and the Japanese. The author has accessed many previously unpublished sources and draws on his own extensive underwater research to give a highly detailed and informed account of the British submarine.
