"To the Gates!" is the eighth episode of the third season of Vikings. It is the twenty-seventh episode of the series overall. It first aired on April 9, 2015. It was written by creator Michael Hirst and directed by Kelly Makin.
The Viking army embarks and Paris goes into lockdown as the army prepares the defense, overseen by Odo. The Vikings are determined to make it through the gates of Paris and will stop at nothing to succeed.
The attack of Paris takes place. The plan is simple: Lagertha, Kalf and Erlendur lead an attack from the city gate, making their way by taking the bridge; meanwhile, Floki, Ragnar, Bjorn and Rollo try to breach the walls from the water. As the attack begins the fate of Paris seems to be a heavy defeat, but Princess Gisla manages to restore faith in the troops by showing the Oriflamme, the holy banner of their patron, Saint Denis. Eventually the defense holds, pushing back the Vikings from all sides. At the gates Kalf understands that the battle is lost, and after dulling Lagertha's senses falls back with a wounded Erlendur and very few survivors. Floki's assault machines are burned with oil and fire. After suffering heavy losses, the Vikings are forced to retreat. While the Franks celebrate their victory, at the Viking camp the warriors have to deal with their wounded, including a badly wounded Bjorn and Ragnar who had been thrown down from the walls. Floki is consumed by his guilt, having trusted by omens of their gods of certain victory. Helga, disgusted by his selfishness, leaves him. Later at night, Ragnar speaks out to Athelstan and tells him that he is bound and determined to conquer Paris.
