It could barely have been said to be a battle. As soon as the pirates that had been raiding Protoss/Terran trade routes realized the size of the force sent to deal with them, they had turn tail and fled, leaving their head quarters abandoned. The fleet pursued, while the Spear of Adun stayed put to catalog the big pile of stolen goods left behind.

Routine work, really, until there was an intruder alert from the cargo hold that had most of the pirate booty stored away.
