Augustin Keller (1754 – 1799!)
On 28 March 1799, in the midst of a period of upheaval the commander of the Helvetic Legion, Colonel Augustin Keller, was promoted to brigadier general and appointed commander-in-chief of the Helvetic Republic's army. However, the hurriedly assembled troops proved completely incapable of fighting a battle. Augustin Keller was released from his duties on 24 May 1799 due to failure and the militia army was disbanded on 12 August of the same year.
