Battle for Trost Arc
After the Colossal Titan breached the walls of Trost, Eren's squad lead by Thomas Wagner was intercepted by a deviant type titan. After swallowing Thomas, the rest of the Titans began devouring Eren's squad. That's when the Bearded Titan appeared, nearly eating Armin. After being saved by Eren after sacrificing himself, Eren later transformed and tore through the Bearded Titan.
