Sabotage the Supply Line (Guristas) (Level 3)

From Battleclinic.com

One of our spies within the Guristas Pirates reported that an ore convoy would be heading through {system name} on a routine trip to supply their construction workers with minerals. We managed to locate the ore convoy and trace its route to a Guristas Pirates outpost in a nearby system; Apparently they are building an extension to the structure of their base there. We will deal with that in due time, but first we need to disrupt their supply lines. So I'd like you to head to out to a rendevouz point with the next ore freight that passes through {system name} and ambush it. You don't need to bring back the ore, just make sure any Guristas Pirates ships in the area are destroyed and the cargo with them.

As you can see in the journal, the encounter looks easy enough. The convoy is being guarded by a small mercenary force, hired by the Guristas Pirates. But I warn you, these ore convoys are probably under heavy surveillance, if there are any Guristas Pirates fighter ships in the vicinity, they WILL attack you as soon as they receive the distress call from their precious convoy.
