War rages throughout our lands. Only the bravest heroes dare strike the Horde where it hurts them most. You are among such heroes.
The blows you have delivered to the leadership of the Horde will open the door for our final assault. The Horde will bow down to the might of the Alliance.
Your deeds will not go unrewarded. Ride on proudly!
-- Your King
One Black War Bear for my troubles.
For those wondering - we encountered virtually no Horde resistance, at least none that could slow us down as we stormed through all the Horde capital cities.
