The 2nd Army Doctor was a French doctor serving in the French army, stationed in Port-Gentil, French Equatorial Africa (modern-day Gabon) during World War I. He worked at a hospital in the seaport, treating both military patients and civilian patients. His colleagues included the Army Doctor, the White Nun, and the Black Nun.
In late December 1916 or early January 1917, he was checking on some patients when a group of Belgian officers and soldiers, including Captain Henri Defense (Indiana Jones), Lt. Baudouin, and Privates Zimu and Juba, passed through the ward, carrying an Ubangi orphan, to visit their comrade, Sergeant Barthélèmy, not knowing that Barthélèmy had died of his gunshot wounds.
While the Belgian soldiers discussed the passing of Barthélèmy with the nuns, and the future of the orphan, the doctor continued to work in the adjoining ward.
It is likely that he may have also treated some of Colonel Pernod's men, many of whom had come down with tropical diseases.
