At the same time, General Louis-Gabriel Suchet attacked the Frauensberg   [48.41173, 9.98812], very close, to the north.

On the same day, the city of Ulm was completely surrounded by Marshals Jean Lannes et Michel Ney, and Generals Auguste Frédéric Louis Viesse de Marmont and Louis-Gabriel Suchet.

In the evening, General Louis Henri Loison  reached the gates of the city, but was pushed back.

The next day, Napoleon decided not to attack the city while Karl Mack von Leiberich  was stalling while waiting for the next arrival of the Russians.

However, fearing the lack of food and after a short bombardment, Mack yielded and negotiated with Napoleon the conditions of a surrender, which took place on October 20.
