Flanders is a region in the north of Belgium.
During World War I, Indiana Jones enlisted in the Belgian Army during May 1916. His company, the 9th Belgian Infantry fought at Flanders and suffered heavy losses which took out all their officers including Captain Cote (though for a time Jacques was suspected of murdering him) which led to the remaining troops being absorbed into the French 14th Company at the Battle of the Somme in August.
