From Capt. Sam Grant (first book in a triology about U. S. Grant)
[Currently reading Lloyd Lewis' Captain Sam Grant. As a boy, Grant came home with frozen feet. His mother first wrapped his feet in smoldering straw afterward wrapped them in bacon. Bacon is expensive nowadays.
Some older officers did not embrace new technology well. "General Worth and other old army officers when the percussion guns and caps were first introduced... they feared that the caps would be lost and the men left helpless, forgetting that powder for pouring in the pan of a flintlock gun was attended with greater risk of loss."
Yep, I'm sure that's a problem even to this day.
