I have been challenged to detail the vocalizations that Oswald made, so I have. You can hear them in this video. They occur at 25:16, 25:17, and 25:18, very distinctly. Then there is another soft muffled vocalization at 25:20.
For a man whose aorta was spurting blood and who had other major blood vessels cut, it seems like an awful lot of vocalizing to do.
