Believing that he had rendered outstanding services during the battle at Rothwaltersdorf on 4 June 1807, Seyssel d'Aix requested the bestowal of the Military Order of Max Joseph.
However, Lieutenant General Von Deroy argued against Seyssel d'Aix's request, stating that his battle activities were more likely to be punished than awarded, if judged in the court of public opinion.
After a short respite at home in the garrison of Augsburg in early 1813, he was returned to the front as commander of a combined Chevau-légers regiment, deployed to Bamberg in 1813.
He proved his mettle in the Bautzen, and was awarded with the Knight's Cross[2] of the prestigious (and personally desired) Military Order of Max Joseph for actions taken on 26 May, when he came to the rescue of the "Pacthod" division.
[3] Seyssel d'Aix was married to Princess Sophie of Yrsch-Pienzenau (1805–1872), who was appointed "Pallastdame" (Lady-in-waiting) of the Queen and was honorary dame of the Order of Theresa.
