Coastal Convoys 1939–1945: The Indestructible Highway describes Britain's dependence on coastal shipping and the introduction of the convoy system in coastal waters at the outset of the war.

It brings to life the hazards of the German mining offensive of 1939, the desperate battles fought in coastal waters during 1940 and 1941, and the long struggle against German air and naval forces which lasted to the end of the Second World War.

Reference is also made to the important role played by coasters during the Dunkirk evacuation in 1940 and the Normandy landings in 1944.
