Jacques Dernier

Jacques Dernier was a member of an elite special unit of Allied soldiers formed in World War II known as the Howling Commandos.

Captain America: The First Avenger
Jacques Dernier was a French soldier who was captured by HYDRA. When Captain America single-handedly assaulted the facility in which he was prisoner, Dernier along with his companions broke free and wreaked havoc on the HYDRA agents, coming back to US military base immediately after.

Shortly after their break-out, Dernier and his comrades were invited to join a special elite squadron led by Rogers himself. Dernier, after a brief conversation in French with Gabe Jones, happily accepted. Along with the other Howlers, Dernier takes part to every assault against HYDRA, until, during the one at Red Skulls's fortress, Cap goes missing in action.

His fate after the events of the WWII is unknown.
