Trained as a tailor, at 23 years old she cut off her hair, put on a male costume she had designed herself and obeyed a mobilisation proclamation. Owing to the speed of mobilisation there were no medical examinations and so she was not discovered at first. Her comrades admired her courage very much and were loyal to her, but during one attack her high voice caused the others to realize that she was female. However, she had got into favour with Bravour [who is this?] and so she was not ejected from the army. Indeed, she was even promoted to corporal after the Battle of Möckern. She was promoted to Sergeant after the battle of Dennewitz and subsequently fought in the battle of Waterloo in 1815.
