Members of 12th Coast Artillery Mine Planter Battery prepare to plant mines from a vessel, during World War II
Film on the Employment and Operation of a Submarine Mine Battery.Members of 12th U.S. Army Coast Artillery Mine Planter Battery prepare for mine planting. They unroll steel cable from a large roll and cut it into lengths of from 500 to 1600 feet, to be fastened, from their respective mines, to a distribution box. The cut cables are each coiled on a rack in a figure eight, with both ends free for connecting. A length of 135 feet is free on each cable for use on the mine planter vessel. Ends of each cable are tagged to identify their respective mines. Coast Artillerymen load the racks on the aft deck of the vessel, along with mine buoys and other equipment. They then thread the free 135 foot length of each cable segment along the sides of the planter vessel from stern to foredeck, where they will be fastened to their respective mines. As the planter vessel pulls away from the wharf, and heads for the mine fields, the mines can be seen lined along her railings. The name of the mine planter vessel, "General J.M. Schofield," is clearly visible.
