I'm a bit more cynical about the wall thing. Its so contrived, its like they came up with it to explain away why the Colonel doesn't just exterminate the apes and needs them for slave labour instead. Because that is actually the sort of thing we are to expect the Colonel would do. But I suppose it's not the kind of movie they wanted to make.
