The northern pier of the eastern principal face of the Arch of Triumph bears on its pedestal, in high-relief, a group representing the Departure of the Army in 1792. The Genius of War summons the nation to arms, and warriors of different ages---and in different costumes---are arming and hastening to battle. This is the work of the sculptor Rude and is considered the most striking as well as the best executed of the four.
