What If an A-10 Warthog Flew Air Support at the Charge of the Light Brigade?

October twenty-fifth, eighteen fifty-four. Six hundred and seventy-three British cavalry are about to ride into the most lethal artillery crossfire ever assembled — three batteries, thirty guns, a valley of death that history has already named. Then, out of the clouds, an A-10 Warthog appears. One pilot. No GPS. Forty minutes of fuel. And a thirty-millimeter GAU-8 cannon that fires eleven hundred rounds per minute at bronze artillery pieces from the nineteenth century. What happens when the most survivable ground-attack aircraft ever built rewrites the worst-ordered cavalry charge in history?
