Who slapped 2 shell shocked soldiers?

This is a Vietnam War website, and just so you'll know, Colonel George S. Patton (the IV or Junior) commanded the 11th ACR (Armored Cav Regt) in the Vietnam War. His father was WWII General George S. Patton, he slapped one (or two) GIs in a hospital rear area for what he believed to be cowardice, since they showed and admitted to no physical combat wounds, but only mental anquish (shell shock, battle fatique, Post Traumatic Syndrome, etc.).

So as not to confuse the two Pattons (father & son), both of whom commanded armored units in war (WWII & Vietnam), it's important to note that only the WWII Patton was involved with that incident. If his son Patton peformed a similar deed in Vietnam, it's not known, and in any rate highly unlikely.
