It says something about our current era that this probably means nothing to most. But the phrasing should tell you this is an updated version of Molly Pitcher, whoever that was.
It’s folklore, sort of. She handed out water at the Battle of Monmouth, and took her husband’s place at the cannon when he was felled.
“For the rest of the day, in the heat of battle, Mary continued to "swab and load" the cannon using her husband's ramrod. At one point, a British musket ball or cannonball flew between her legs and tore off the bottom of her skirt. Mary supposedly said something to the effect of, "Well, that could have been worse," and went back to loading the cannon.”
Stories like this reappear in times of war.
