British Submarines Combats In The Second World War [EPUB ebook] 

As a result of the earlier changes, the Royal Navy entered the Second World War as a disparate force of veterans of the First World War, interwar vessels limited by strict adherence to treaty restrictions, and later unrestricted designs. Although smaller and relatively older than during the First World War, it remained the leading naval power until 1944–45, when it was overtaken by the United States Navy. In this book I will focus more on the tactical and technical decision-making levels, basing the tasks on examples taken from situations experienced by British submarine crews in the Second World War. However, I will insert their missions into a broader framework of submarine warfare involving the strategic, operational, strategic and political decision-making levels, in order to meet the greatest threat that Great Britain had to face during the conflict, which was that of a German amphibious invasion, the objective of Unternehmen Seelöwe (Operation Sea Lion). And in the development of this simulation I will use the U-Boot board game from Galápagos Jogos.
