Facing the Flag or For the Flag (French: Face au drapeau) is an 1896 patriotic novel by Jules Verne. The book is part of the Voyages Extraordinaires (The Extraordinary Voyages) series.

Like The Begum's Millions, which Verne published in 1879, it has the theme of France and the entire world threatened by a super-weapon (what would now be called a weapon of mass destruction) with the threat finally overcome through the force of French patriotism.

It can be considered one of the first books dealing with problems which were to become paramount half a century after its publication in World War II and the Cold War: brilliant scientists discovering new weapons of great destructive power, whose full utilization might literally destroy the world; the competition between Superpowers to obtain overwhelming stockpiles of such weapons; and, efforts of other nations to join the nuclear club.

Thomas Roch is a genius French inventor, who came up with the idea of the Fulgurator, a weapon "whose action upon the atmospheric strata was so terrific that any construction, warship or floating battery, within a zone of twelve thousand square yards, would be blown to atoms", so that "the state which acquired it would become absolute master of earth and ocean".

Jules Gabriel Verne (French pronunciation: [ʒyl vɛʁn]; February 8, 1828 – March 24, 1905) was a French author who pioneered the science fiction genre. He is best known for his novels Twenty Thousand Leagues Under the Sea (1870), A Journey to the Center of the Earth (1864), and Around the World in Eighty Days (1873). Verne wrote about space, air, and underwater travel before air travel and practical submarines were invented, and before practical means of space travel had been devised. He is the second most translated author in the world (after Agatha Christie). Some of his books have also been made into live-action and animated films and television shows. Verne is often referred to as the "Father of Science Fiction", a title sometimes shared with Hugo Gernsback and H. G. Wells.

Jules Verne was born in Nantes, in France, to Pierre Verne, an attorney, and his wife, Sophie Allote de la Fuÿe. Jules spent his early years at home with his parents in the bustling harbor city of Nantes. The family spent summers in a country house just outside the city, in Brains on the banks of the Loire River. Here Jules and his brother Paul would often rent a boat for one franc a day. The sight of the many ships navigating the river sparked Jules's imagination, as he describes in the autobiographical short story "Souvenirs d'Enfance et de Jeunesse". At the age of nine, Jules and Paul, of whom he was very fond, were sent to boarding school at the Saint Donatien College (Petit séminaire de Saint-Donatien). As a child, he developed a great interest in travel and exploration, a passion he showed as a writer of adventure stories and science fiction. His interest in writing often cost him progress in other subjects.
