Here's an interesting cinema tidbit.
In "55 Days At Peking", the character Major Matt Lewis, was loosely based on the real-life officer in charge of the marine guard at the U.S. Legation, then Captain, later Lieutenant General, John Twiggs Myers USMC (1871-1952). Myers was in the forefront of some of the toughest fighting in the besieged legations, wounded during the fighting on the Tartar Wall.
Myers also later commanded the Marine Corps forces in Tangier during the Pedicaris Incident, and as such was portrayed as Captain Jerome by Steve Kanaly in the movie "The Wind and the Lion".
Two of my favorite movies of that era.
