Attack On Titan - Season 4 - Episode 1 - The Other Side of the Sea [English Subbed]

Summary :- Marley besieges Fort Slava, aiming to end their four-year conflict with the Mid-East Allied Forces sparked by their defeat in Shiganshina. Warrior candidate Falco Grice is saved by his brother Colt, who returns him to the trenches nearby. The presence of an armored train prevents Marley from deploying its Titans. Warrior candidate Gabi Braun is approved to destroy it by Marleyan Commander Magath, which she succeeds in through the use of perfidy.

The deployment of Galliard and Pieck clears the Mid-East trenches, which allows their airborne operation to begin. Zeke Jaeger uses his Titan power to transform Eldians into Pure Titans, creating a powerful airstrike. The Armored Titan joins the battle, destroying the remaining anti-Titan artillery with the Jaw. With the fort secure, Zeke uses his Beast Titan's pitching to sink the naval fleet stationed nearby, however, artillery fire from the ships heavily damages the Armored Titan. A peace treaty is signed, but the battle's outcome reminds Marley of the growing need to acquire the Founding Titan.
