Are there any battles won by using meteorological conditions?
The Dutch contingency plan really worked. Napoleon was at a loss when he saw the raging flood, so he had to order the whole army to retreat. At the same time of withdrawing troops, Charles Piglio, commander-in-chief of the French army and Napoleon's teacher, suddenly ordered to stop withdrawing troops. The soldiers kept talking: "Why on earth is this?" The original learned Charles? Pigliou found that some local spiders were spinning a lot of webs. This indicates that dry and cold weather is coming, because spiders are very sensitive to the humidity change of the outside air. Sure enough, the European continent was hit by a cold wave, strong cold air swept across the European continent, and the rolling flood froze overnight. Stepping on the ice and snow, the French army crossed the Val River, conquered and occupied Utrecht, a traffic fortress in the hinterland of the Netherlands, and successfully completed the operational plan. Afterwards, he said: If it weren't for the "living weather instrument"-the spider gave me this correct "attack order", we couldn't have conquered the enemy's important place so quickly.
