Coastal Command, created in 1936 alongside Fighter and Bomber Commands in the reorganisation of the RAF in its preparations for the coming war, was Britain's mainstay in the battle against the German submarine. As more and more Allied merchantmen were sunk during the long voyage from North America, the Mediterranean, and points south, tracking down the U-Boats became a constant struggle against harsh weather on long-distance patrols out over the Atlantic and Bay of Biscay. To counter the threat, Coastal Command established a ring of bases stretching from Scotland and Northern Ireland to Iceland, and from south Wales and south-western Britain to Gibraltar and the Azores, all 53 of these stations are covered in this book. 700 illustrations
