The Ulm Campaign September-October 1805.
The 'Battle of Ulm', part of the
Napoleonic Wars, was fought in
1805 near
Ulm in
Württemberg. It was a great victory for Napoleon, resulting in the surrender and destruction of an entire
Austrian army.
In 1805, the
United Kingdom, the
Austrian Empire,
Sweden, and the
Russian Empire formed the
Third Coalition to overthrow the
French Empire. When
Bavaria sided with
Napoleon, the Austrians, 72,000 strong under
General Mack von Leiberich, prematurely invaded while the Russians were still marching through
Poland. This mix-up was caused by the fact that while the Austrians used the
Gregorian calendar, the Russians were still using the
Julian calendar. This meant that their dates did not correspond, and the Austrians were brought into conflict with the French before the Russians could come into line.
Napoleon had 177,000 troops of the
Grande Armée at
Boulogne, ready to invade England. They marched south on
August 27 and by
September 24 were in position facing General Mack, around
Ulm, from
Strasbourg to
Weißenburg in Bayern. On
October 7, Mack learned that Napoleon planned to march round his right flank so as to cut him off from the Russians who were marching via
Vienna. He accordingly changed front, placing his left at Ulm and his right at
Rain, but the French went on and crossed the
Danube at
Neuburg.
Trying to extricate himself, Mack attempted to cross the Danube at
Günzburg, but clashed with the French VI Corps at
Elchingen on October 14 in the
Battle of Elchingen. The Austrians lost 2,000 men and returned to Ulm. By
October 16, Napoleon had surrounded Mack's entire army at Ulm and three days later Mack surrendered with 30,000 men, 18 generals, 65 guns, and 40 standards.
Some 20,000 escaped, 10,000 were killed or wounded and the rest made prisoner. About 6,000 French were killed or wounded. At the surrender, Mack offered his sword and presented himself to Napoleon as "The unfortunate General Mack."
[Blond, G. ''La Grande Armée''. Castle Books, 1979. pg.59.] Bonaparte smiled and replied, "I give back to the unfortunate General his sword and his freedom, along with my regards to give to his Emperor".
Francis II was not as kind, however. Mack was
court martialed and sentenced to two years' imprisonment.
The Battle of Ulm is considered one of the finest examples of a strategic
turning movement in military history.
