The Nameless Soldiers

is the 2nd chapter of the 20th volume and the 80th chapter overall of the Attack on Titan manga, written and illustrated by Hajime Isayama.

Overview
The Survey Corps watch in shock the motionless body of Eren's Titan slammed atop Wall Maria, wondering if he's still alive, but they can't be distracted much since the Colossal Titan keeps aproaching the Wall. Jean orders his comrades to draw his attention while Mikasa shoots Thunder Spears to the Titan's nape, but Bertolt easily sees through their scheme and releases a burst of hot steam, deflecting the Thunder Spears and injuring his former friends. Armin goes to help the wounded Mikasa, but admits that he still doesn't have any plan to take them out of their predicament. To make matters even worse, they watch in horror as a fully recovered Armored Titan stands up ready to rejoin the fight.

Meanwhile, Levi urges Erwin to order the retreat and save the few survivors, but Erwin reveals that he still has an strategy to defeat the Beast Titan, though at the cost of his and the new recruits' lives. He admits that the only thing that stops him is his desire to live long enough to see the basement, but Levi prompts him to forget his dreams and do what he has to do.

Erwin leads the recruits into a direct suicide attack against the Beast Titan to serve as decoys while Levi sneaks through the horde of Titans, using them as trees to maneuver with the 3DMG as he approaches the Beast Titan in order to attack him by surprise. Erwin and his troops continue riding towards the enemy, using the Signal Flares to obstruct his sight. As Zeke launches a rain of rocks towards them, Erwin and his horse are quickly hit by a projectile.

Summary
Atop Wall Maria, Eren lies immobile after being brutally slammed there by the Colossal Titan's kick. Erwin and Levi watch the scene in shock while Mikasa wonders if he's still alive. However, Jean assures her that Eren is alive and shouts everyone to focus on the Colossal Titan, who continues on his way to attack the Wall.

Jean orders Connie and Sasha to help him draw Bertolt's attention while Mikasa shoots Thunder Spears to his nape. The three attempt to distract him with insults and nicknames, but Jean realizes they are being too obvious and Bertolt probably has already realized that Mikasa is behind him; though still hopes that she will be able to hit him. Mikasa launches the spears but Bertolt responds by releasing a massive burst of hot steam, which deflects the spears as well as blows away the grapple hooks of her maneuver gear and violently pushes everybody back, causing them superficial burns.

Armin comes to help Mikasa, who was hit in her right arm by a Thunder Spear shrapnel, though she replies that the wound isn't deep. She asks him if he has devised a plan to counterattack, but Armin admits that he still doesn't have any. At that moment, they and Jean hear a sound at their backs, and watch in horror that the Armored Titan has fully recovered and is standing ready to return to the fight.

Meanwhile, the Beast Titan continues launching rocks at the Survey Corps' hiding spot. Levi tells Erwin that at that rate it won’t be long before he turns it all into rubble, and urges him to order the retreat if he doesn't have any counterattack method left, using Eren to carry the few survivors.

As they speak, the terror and desperation seize the new recruits, with Marlo Freudenberg trying to calm down
