From the late 1940s to the 1970s, flotillas of Her Majesty's minesweepers trawled the world’s waters seeking unexploded ordnance. Many of these vessels were leftover from the First World War, and were again utilized after the fall of the Axis powers. Many were made of wood, aluminum, or other non-ferrous materials, to resist triggering magnetic mines, and were soundproofed to protect against acoustic mines. Minesweeping was quite literally slow-going work, since many of these minesweepers were small ships powered only by diesel engines. And the methods for detecting the mines were primitive: in the “Double-L Sweep” method, two ships would tow an electrical cable between them that emitted a magnetic field in the seawater. Moreover, the dangerous nature of the job meant that the casualties did not end even i
