Special Features
The British thought these were often laid with a time-release mechanism that would keep the mine on its sinker for several days after sowing, but none of those recovered by mid-1917 had any such mechanism installed. In light of that fact, they concluded that delayed unmoorings were perhaps unintended and attributable to mechanical quirks.[3]
