 A number of the ordinary methods to refloat a ship couldn't be used because she was very nearly empty and so nothing could be off-loaded and the rocky bottom meant that it couldn't be excavated out from underneath her.The first attempt used brute force provided by the cruisers and "Kerch" to unsuccessfully tow her off.Several other attempts were made using explosive charges to create shock waves that would pivot her stern into deeper water in combination with tugs attempting to pull her around, but these were counterproductive in that several holes were blown in her sides which flooded several compartments and grounded her that much more firmly.
