Where were the scouts when the titans attacked in the beginning?


Where were Levi and the scouts during the original attack in episode 1 when
the titans first broke through the wall?




The scouting regiment was wiped out by the colossal titan before the attack on
Wall Maria and those who were not eaten were too injured to fight, so they
could not fight the titan invasion. During the fall of Trost, and the battle
for Trost, the Levi squad and the Survey Corps were gone on an expedition
outside of Wall Rose, finally returning just in time to save the remnants of
the soldiers sent to help get Trost back from the titans.
