The Man Behind the Gun (1953) [Senator Mark Sheldon]: Drowned in the river at the end of a struggle with Randolph Scott.
The Last Command (1955) [Dr. Summerfield]: Stabbed to death with a bayonet in the Alamo chapel by the Mexican soldiers. His death is shown in the background as more soldiers go down a passage towards Sterling Hayden. (Thanks to Brian).
