I think I would know the difference between scorching your land and burning down your city.
"The Russians retreated and Napoleon was able to enter Moscow, assuming that the fall of Moscow would end the war and that Alexander I would negotiate peace. However, on orders of the city's military governor and commander-in-chief, Fyodor Rostopchin, rather than capitulating, Moscow was ordered burned. Within the month, fearing loss of control back in France, Napoleon left Moscow."http://en.wikipedia.org/wiki/Napoleon_I_of_France
