Ability Background
The mud on the roads represents a crucial element in deciding who wins the war. A notable example of this can be found in the year 1812, during Napoleon's invasion on the Russian Empire, in which the French were forced to retreat because of the problems caused by the muddy terrain, these problems consist in the slowing down of the refreshing troops, immobilization of the cavalry and other logistical difficulties of supplies.
Another quite similar example, and more recent happens during the Second World War, when the Wehrmacht (the German Defense Force) prepares to invade Russia, suffering the same luck that their French counterparts, because the mud caused them terrible problems when their armored cars, trucks and artillery pieces remained immobilized in the soil, supposing this in addition an attack to the morale of the Germans that were in the Front, deprived of the basic supplies of war that did not arrive due to the mud.
