How does Lillian Hellman use imagery in Six Plays?

Imagery:

He fought in France so that this country and all the others could stay Free. When he came back they stripped him at the docks--his gun, his uniform, the dignity they’d allowed him for a few mad years because the world needed men to fight and be ready to sacrifice themselves for something called Freedom.

Now at last it’s over. No matter how hard-arsed the boer on this farm wants to be, he cannot move Outa Jacob. He has reached Home.
