By afternoon the Swedes had finished their preparations and moved forward at 2 p.m. At that moment it got colder, the wind changed, and the snowstorm blew directly into the eyes of the Russians.[1]:686 Some Swedish officers asked to postpone the attack until the end of the storm, but Charles saw his opportunity and advanced on the Russian army under cover of the weather.[2][3] The Swedes attacked with two highly dense shock groups, quickly approached the Russian positions and gave a volley, after which the Russians "fell like grass". At first, the Russians vigorously resisted: "They returned a heavy fire and killed many fine fellows", but within 15 minutes the Swedes filled the ditches with fascines, broke into the fortifications with cold steel arms, and "a terrible massacre" began.[4]
