You are a Paratrooper, you just dropped out of your transport, and you are wounded.
You have to communicate with 'the locals' because you need some form of treatment.
But you are in France, there are no other troopers nearby, you only have your little
blue book: the War Departments TM30-302 French Language Guide (JUNE 21, 1943 edition).
You have never, ever spoke French, and now you wish you could. And you can... can you ?
