Into the minefields : British destroyer minelaying : 1916-1960 /Peter C. Smith.

"During the early years of World War I the existing minelaying vessels in service with the Royal Navy were found to be far too slow to penetrate into the strategically important waters around Holland, Denmark, Germany and Sweden under the cover of darkness and survive. As a result, a flotilla of fast destroyers was created that could be readily converted from their normal role into minelayers."--Provided by the publisher.
