That video brought to mind the song of which Tom B reminded us. Barbara Frietchie by John Greenleaf Whitter
And the excerpt refers to the actions of an officer of the forces at war war the Northern States.
A shade of sadness, a blush of shame,
Over the face of the leader came;
The nobler nature within him stirred
To life at that woman's deed and word:
"Who touches a hair of yon gray head
Dies like a dog! March on!" he said.
