In the Second World War we had all kinds of problems with mud. The problem of winching trucks out of mud was a big issue. It was solved by driving a metal stake into the ground, slanted slightly backward so that the cable to the truck would slide to the ground .
When enough pressure in put on the stake , it tends to lean toward the force, and pull out . In order to prevent that , the stake had a short section of chain attached to the top . The short chain had a ring at the end. A second stake would be driven through the ring . Now it is much harder to tip the first stake, but not impossible on a very hard pull. If there was any doubt , a third or fourth stake was used .
Even in quite unstable soil , we were able to winch the truck out, in almost all cases .
Trucks carried their own winches on the front bumper . When necessary , we would run all of the cable out , so that the greatest pull was on the axel of the winch . A full spool has far less strength than an empty one .
Empty - - more power , less distance. Full - - - more distance, less power
