In World War II he was a general commanding the Third Army Group stationed along the river Rhine manning the Maginot Line.

In the interbellum, he commanded the 58th Brigade, the 15th Infantry Division and the 16th Army Corps.

In October 1939, he took command of the French 3rd Army Group, which covered the section of the Maginot Line along the Rhine and the Swiss frontier.

He and his command surrendered after 25 June as German Panzer units had reached the Swiss border and cut off the Maginot Line from the rest of France.
