You're in Command Now, Mr Fog

The Yankee sharpshooter turned out to be a lousy judge of character. He had three officers in his sights, a captain and two lieutenants. If he killed the right one, the Union Army’s victory at the Battle of Martin’s Hill would be guaranteed. So he made his choice and killed the Rebel cavalry’s commanding officer, Captain von Hartz.
Big mistake.
He should have concentrated on the small, insignificant-looking first lieutenant instead. Because the death of Captain von Hertz put Dusty Fog in command of the Texas Light Cavalry’s hard-riding, harder-hitting Company ‘C’. And with Dusty at their head, there was going to be hell to pay for the Bluebellies
