Just to give a brief idea.
The entire Baltic states area has just gone thru a massive thaw followed by heavy rain,- temperatures hit +7C.
That's quite unusual for this time of year, and can lead to a morass of mud.
Normally it could be the ground would be quite deeply frozen, but not this year.
(It stopped Hitler's army in October 1941.)
That would explain the very impressive stick in the mud or in french "bien embourbé!".
It's going to be a pig's ear to get back out, especially as in the next 48hrs it's all going to freeze solid like concrete.
