When Napoleon was crowned emperor on 2 December 1804, the Consular Guard's Marine battalion consisted of 820 officers, non-commissioned officers and ratings. Napoleon integrated that battalion into the Imperial Guard in 5 crews totalling 818 officers and men. Its ranks were those of the navy, not the army, and each crew was commanded by a Capitaine de frégate or Capitaine de vaisseau and four other officers, with 15 non-commissioned officers and 125 ratings.
