 At Vichy, the counter-admiral Auphan was part of the tenant groups which harbored a political view of attentisme (the act of waiting and refraining until situations become more clear and precise).

A partisan of a suspension of combat between French and Americans during the Anglo-American disembarking of November 8, 1942 in North Africa, he opposed those who wanted to continue to mount combat along the Germans.

In 1956, the State Council gave him back his rank and rights for pension.
