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.

Humanity's Comeback arc
Five years after the fall of Wall Maria, the Colossal Titan appears again and breaks down the outer gate.

The Struggle for Trost arc
Eren Jaeger attempts to kill 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. Evacuation preparations are made as the district is invaded by Titans and the trainees are placed under the command of the Garrison Regiment.

Dividing into teams, the trainees engage the Titans to protect the evacuation, resulting in a large number of casualties. Notable deaths include Thomas Wagner, Mina Carolina, Nack Tierce, Milieus Zeremski, Franz Kefka, Hannah Diament, Tom, Ian Dietrich, Marco Bodt, and Mitabi Jarnach.

Despite the losses, the entire civilian populace successfully evacuates 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 and the other trainees discover his mysterious ability to turn into a Titan. This prompts the Garrison, under the command of Dot Pyxis, to work with Armin Arlelt and devise a plan to seal the breach by having Eren's Titan block it with a large boulder. There are heavy losses getting the plan to work, but Eren successfully blocks the damaged gate with the boulder. Soon after, the Scout Regiment arrives and aids the Garrison in clearing out the remaining Titans.

Trivia

 * It is rather ironic that Trost comes under Titan attack the most, since "Trost" means 'solace' or 'comfort' in German.
 * People from Trost include Thomas Wagner and Jean Kirschtein.
