Created in Morocco following the liberation of French North Africa, the division fought in Corsica, Italy, metropolitan France, and Germany.

By the end of November, the 4th DMM had moved to Mulhouse in Alsace, where it was engaged in fierce combat to liberate the city.

At the height of winter, it then participated in the reduction of the Colmar Pocket by advancing on the Thann-Cernay-Soultz-Rouffach axis from 20 January to 5 February 1945.

After some weeks of rest, the Division was directed towards Strasbourg, and crossed the Rhine, entering Germany on 16 April 1945.

Its mission was to bypass the Black Forest by its eastern edge, and reach the northern border of Switzerland as quickly as possible.
