The phrasal verb get somebody out means: "to help someone escape from or leave a place." I hvae heard get someone "away" is used in this sense too, but I couldn't find any reliable dictionary which approves that. I need to make sure whether they are interchangeable or not. Please have a look on my example below and let me know whether thay can be substituted for each other in this context or not:
Dugging a tunnel under the wall, they got five other prisoners out of the prison.
Dugging a tunnel under the wall, they got five other prisoners away from the prison.
Are these two sentences mean the same thing?
