Supplies are running low in Ugrukhôr's encampment, but they might always run lower....
'Greetings, friend. As you reported, it seems that Ugrukhôr's forces are running low on supplies. If we were to destroy the few supplies that remain, we might sufficiently enrage the Orcs into attacking Gothmog's forces. And wouldn't that be a pity?
'Go forth and destroy the supplies that you find, and we will see if I am right.'
Supplies are running low in Ugrukhôr's encampment, west of Barad Angarth.
You should seek out and destroy the supplies.
You destroyed some of the supplies in Ugrukhôr's camp.
You should return to Dolenthol and inform him of your victory.
