"After he was released from Auschwitz" is a subordinate clause. Remember, subordinate clauses are also known as dependent clauses. These types of clauses can NOT stand alone by themselves.

"from Auschwitz" is a prep. phrase.
"Mr. Frank returned to the attic"  is a complete thought.
"to the attic" is also a prep. phrase.
