If the Formation would suffer more than one hit, this Formation suffers all hits but one, which the targeted/absorbing Formation suffers.
When this Formation Routs, it does not cause the loss of a morale cube.
Finally, while I've got your attention: as long as Greene's Right is in play, you can place dice on TWO Dark Blue cards each turn. Why is this note on this card, and not on Greene's Right? Because I didn't have room on that card. And folks wonder why the cards don't have art on them...
If rolling five or more dice during your Roll Phase, you need a four-die straight to earn a cube. If rolling four or less dice, you need a three-die straight to earn a cube.
When there are FIVE cubes on this card, Geary's Division arrives, bringing the late hour battle to a close. The game ends immediately in a UNION VICTORY.
If you choose to do so, your attacking Formation suffers one extra self hit.
