Galloping pneumonia? I’ve heard of walking pneumonia (dad had it a few times), but never any other gait.
You’re not referring to TB?
Anyway, apparently, he did get bad pneumonia due to strep. He probably started with strep throat (sore throat) and never took care of it and got pneumonia. Seems he went a good 10 days before going to the hospital (or ANY medical attention).
Yeah, they all kill given enough time and inattention.
