Le Régiment de Sambre et Meuse (lit. "Sambre-et-Meuse regiment") is a French song and military march by Robert Planquette and Paul Cezano. The original poem was written in 1870 by Paul Cezano, in the wake of the Franco-Prussian War and the first days of the French Third Republic. The references to the Army of Sambre-et-Meuse set Republican, soldierly mood. The next year, music was composed by Robert Planquette. In 1879, it was arranged as a military march by Joseph François Rauski.
