Lines of Battle: Quatre Bras 1815. Brunswick hussar.
This game is the best Pub Battles edition so far. If you want a little more personal involvement by the HQs here is a really great variant I've played a few times.
Before combat dice are rolled, an involved unit's HQ may take personal control of the unit. The HQ is moved adjacent to the unit. If the unit suffers one or more hits in any round of that combat, the HQ may cancel one hit by flipping to its spent side.
The HQ must be fresh and within command range.
If the opponent rolls all sixes, then the HQ must absorb one Hit and the cube is flipped so that the name of the Commander is upside down, signifying a severe enough wound that the leader is no longer able to carry out his duties and is replaced by another. This remains flipped and may no longer carry out any function other than to place an attacking unit in command range.
This would work for the other games in the Pub Battles series. It reminds me of miniatures rules and attaching leaders to get a combat bonus at the expense of losing command/control bonus.
