Trost District (Anime)

The Trost District (トロスト区) is a town located on the south edge of Wall Rose. Because Trost is the town closest to the breach in Wall Maria, it is the town that most frequently comes under attack from Titans.

People from Trost include Thomas Wagner and Jean Kirschtein.

Humanity's Comeback arc
Five years after the fall of Wall Maria, the Colossal Titan appears again and breaks down the outer gate, causing the district to be invaded by Titans. Eren makes an attempt at killing the Colossal Titan, but it vanishes before he can reach its nape. After regrouping with the other trainees, he finds out they were too scared by the Titan to help him attack.

The Struggle for Trost arc
After the breach, the trainees engage the Titans in the district, resulting in huge casualties to the Garrison Regiment. Notable deaths include Thomas Wagner, Mina Carolina, Nack Tierce, Milieus Zeremski, Franz Kefka, Tom, Ian Dietrich, Marco Bodt, and Mitabi Jarnach, among others. However, the entire civilian populace successfully evacuated in the hours immediately following the breach, thanks to the efforts of soldiers such as Mikasa Ackermann. This is also the district in which Eren Jaeger and the other trainees discover his mysterious Titan-shifting ability. This prompts the Garrison Regiment, under the command of Dot Pyxis to devise a plan to seal the breach using a large boulder. The district is saved when Eren changes into his Titan form and successfully blocks the breached gate with the boulder. Soon after, the Scout Regiment arrive and aid the Garrison in clearing out the remaining stragglers.

Trivia

 * It is rather ironic that Trost comes under Titan attack the most, since "Trost" means 'solace' or 'comfort' in German.
