I'm reading Cryptonomicon by Neal Stephenson and came across the following sentence. It's taken from chapter 69, "The General":
It is physically impossible for him to get out of the turret. Even if he could, it would just lead to his getting arrested.
I'm not sure but the highlighted his in the sentence seems incorrect to me. In my opinion it should be replaced by him or the "getting arrested" should be changed to "arrest". Could someone, please, explain this to me?
