Blue Division (Second French Empire)

Created during the Franco-Prussian War of 1870, the Blue Division is the name given to the division d'Infanterie de Marine which - for the first time in the history of the marines - joined 'marsouins' or marine infantry (4 regiments) and 'bigors' or marine artillery (1 regiment).

Commanded by general de Vassoigne, it was made up of two brigades :

The Blue Division formed part of the 12th Army Corps under the command of Barthélémy Louis Joseph Lebrun, which was the last unit to arrive at Sedan after having made a last attempt to retreat with general de Wimpffen. It fought at Bazeilles on 31 August and 1 September 1870. The town was retaken and abandoned four times, with 2,655 French and 5,200 Bavarians dead, inspiring the patriotic painting Les dernières cartouches (The Last Cartridges) by Alphonse de Neuville. Each year the marines celebrate the anniversary of the battle, ending the ceremonies with the unit's battle cry, "Au nom de dieu, vive la coloniale" ("In God's name, long live La Coloniale") - the unit had God Himself as its patron saint.
