The Taughâsh tribe defending the Mirk-eaves against the Malledhrim rely heavily upon stores brought to their encampments before the invasion began.
'The battle goes well thus far, ${PLAYER}, but the Orcs in the nearby fortresses are proving tenacious. It seems they have also laid in supplies for a prolonged siege, should it come to that... but we cannot afford to be tied down here for so long, or the might of Dol Guldur shall push us back into the Anduin!
'We bid you fight your way into those camps and destroy their supplies. This will both weaken their defence and ensure that none of them are able to retreat with valuable stores back to their dark tower.
'When you have completed this task, return here to me for further instructions.'
Supplies can be found at Durbúrz-stazg to the north of Echad Sirion and Fállug to the south.
Fuirgam has asked you to find and destroy the supply-crates in the Orc-fortifications of the Mirk-eaves.
Fuirgam's Aide is at Echad Sirion, on the eastern banks of the Anduin.
You should return to him with news of your success.
