In 1920, Touzet du Vigier was assigned to the staff of General Henri Niessel, the head of the French military mission to newly independent Poland, which was involved in a war with Bolshevik Russia.

Touzet du Vigier's direct superior while training the Polish troops was future French president Charles De Gaulle.

He continued to lecture others on the importance of mechanized cavalry, and, promoted in 1938 to lieutenant colonel, he was constantly reassigned to areas where his technical knowledge would prove useful.

When France fell to the Nazis, Touzet du Vigier, now serving the Marshal Petain's Vichy regime, was chosen to head the cavalry department of the army headquarters in Versailles.

[2] When the Allies invaded Africa, Touzet du Vigier switched sides to that of De Gaulle's Free French.
