Higonet was named Captain on 4 January 1806 and was knighted in the Order of the Legion of Honour on 14 May 1806. During the battle of Auerstedt (14 October 1806), captain Higonet showed skill and daring, but his brother, Colonel Joseph Higonet, died there (his name would later be engraved under the Arc de Triomphe, Eastern pillar, column 18). He distinguished himself again on 8 February 1807 during the battle of Eylau, where he was again wounded in the left leg and the lower abdomen. In 1809, he took part in the battles of Eckmühl (21-22 April 1809) and Wagram (5-6 July 1809). His heroic conduct was rewarded on 22 June 1809 by his assignment to the 1st Infantry Grenadier Regiment from the prestigious Imperial Guard.
