After training, the Charlemagne Brigade was reclassified as a division as the 33rd Waffen Grenadier Division of the SS Charlemagne (1st French) ("33. Waffen-Grenadier-Division der SS "Charlemagne" (französische Nr. 1)"). It had 7,340 men at the time of its deployment to the Eastern Front in February 1945. It fought against Soviet forces in Pomerania where it was almost annihilated during the East Pomeranian Offensive within a month. Around 300 members of the unit participated in the Battle in Berlin in April–May 1945 and were among the last Axis forces to surrender.
