De Gaulle rejoined the 33rd Infantry Regiment as a sous-lieutenant

In October 1912 he rejoined the 33rd Infantry Regiment as a sous-lieutenant (second lieutenant). The regiment was now commanded by Colonel (and future Marshal) Philippe Pétain, whom de Gaulle would follow for the next 15 years. He later wrote in his memoirs: "My first colonel, Pétain, taught me the art of command".
