Cis the Beachco m ber Wikipedia He knows the beach like no other. Beachcombing is his passion, and passions should be shared with other people. Are you ready to become initiated in the mysteries o f the strangest flotsam and jetsam? NAVAL MINES, DECORATIVE AND DEADLY The beach was la rge ly o f f lim its durin g World War I (see M ahieu E. in this issue). It was a dangerous place, p a rtly because a ll sorts o f w ar m aterials, in p a rtic u la r naval m ines gone ad rift, were washed ashore. M ines fo u n d on the beach were deactivated and often used as decoration. T h e N o r t h S ea BY M IN EFIELD S c lo sed off The w a rring parties extensively deployed naval mines in the North Sea and beyond du rin g WWI. The mines were cheap and effective. The Germans targeted the routes of m erchant and navy ships heading for and depa rting from the United Kingdom. The Allies tried to cut U-boats o ff w ith naval mines in the Strait of Dover and the northern part o f the North Sea and keep the German fleet confined. As part o f this strategy, the Americans and British developed the North Sea M ine Barrage in the final years o f the war by laying 70,000 naval mines between the Orkneys and Norway. Earlier on (in 1915), the Allies had blocked the entrance to the English Channel w ith a chain o f m inefields (the Dover Barrage, see map) to confine German subm arines to the North Sea. In all, some 235,000 naval mines were laid in m inefields in WWI. The best-known are the spherical m etal devices w ith characteristic protuberances (Hertz horns), but various types existed. Quite a few o f these mines broke from th e ir m oorings and went ad rift after a w hile. For instance, the British M ark 3 naval mine, which was ignited by a p ro tru ding floa t that rotated upon contact w ith a ship, was not very successful: hundreds o f these mines washed up on the surrounding beaches. Just like the N o rth Sea M in e Barrage constructed betw een the O rkneys a n d N o r w a y in 1918, the D over B arrage consisted o f a chain o f m inefields la id b y the A llie s to keep the G erm an fleet, in clu d in g submarines, co n ta in e d to the N o rth Sea as much as possible (W ik ip e d ia j D e c o r a t io n Once washed ashore and deactivated, mines often got a second life. People enjoyed posing next to them , as is s till customary w ith o f other rem arkable objects such as wrecked ships or beached marine mammals. A fterw ards, they could be used as decoration in the officers’ mess or as a flow er tub in the garden. Naval mines from WWI can s till be found in m any places as eye-catchers or decoration. However sin ister these old spherical mines w ith th e ir protuberances may be, they do look the part. And being cast-iron, they are solid in an old-fashioned way. I pass by tw o such mines alm ost every day, displayed at the entrance o f the Naval M ine Warfare School (EGUERMIN or Ecole de Guerre des M ines) in Ostend. I hadn’t noticed them u n til now...
