For the most part, the titles (about 68%) were granted for military valor, but nobility was also conferred for civil service. In total, from 1808 to 1814, 388 people received the title of Count, 1090 persons were given the title of Baron, and 1600 individuals – Chevalier. .
A Letter Patent conferring the title of the Imperial Baron on the Divisional General, Commander of the Order of the Legion of Honor, Jean-Francois Leval (1762–1834), was issued in Bayonne on June 1 , 1808, three months after the decree of March 1, 1808, reconstituting the nobility. Leval began his military career joining the infantry regiment of Poitiers in 1779 as soldier. Twenty years later, in 1799, he was promoted to Division General. Leval took part in the battles of Fërus (1794), Jena (1806), Preussish-Eylau (1807), in the Pyrenean wars. The document identifies that the hereditary title was granted to him for "selflessness and loyalty" shown during his service of the state and the Emperor.
The second Letter Patent conferring the title of of Chevalier de Mussignère on Eugene Balthasar Benard (1758–1833), Chevalier of the Legion of Honor, Mayor of the 8th Arrondissement of Paris. The document is dated, "Saint Cloud, September 10, 1808."
Both parchment Letters are written in the name of "Napoleon, by the Grace of God, Emperor of the French, King of Italy, Protector of the Confederation of the Rhine" and bear his signature–autograph. The documents were sealed (seals are now lost) by Archchancellor Cambacérès and authenticated by his signature. On the back of the Letters there are records of their registration by the Council of Seals and Titles and entry into the registers of the Senate. A granted title was accompanied by establishing a coat of arms, which each document describes in detail and reproduces in paint.
In Napoleon's heraldry, there existed more strict hierarchy than in the traditional one. There was strict criteria for making coat of arms. Decorations helped to identify the official duties and positions of its owner. So, in the top left qurter of the heraldic shields of military barons there was a silver sword on a red field. The coats of arms of the chevalier or knights of the Empire, as a rule, included a silver cross of the Legion of Honor placed on a red field. These elements can be seen in the coats of arms assigned to J.-F. Leval and E.-B. Benard.
