Chief Grimbriar wants you to deal a significant blow to the brigands' leadership in Bree-land.
'Now listen here. I am not going to invite the aid of those Rangers out of the wild. The Men of Bree are capable of defending their own lands from the threats they face, and we will not rely on strange folk for assistance.
'This information speaks of the captain who led the raid on Dogwood's Farm and his current location. We have a chance to strike a telling blow against these brigands and find out more about them.
'It appears that the leader established a camp within a thick copse of trees behind the knoll to the west. The knoll in question is to the south of Dogwood's Farm. Let us strike this blow for the Men of Bree-land.'
The brigand leader is encamped in a copse of trees to the west of Grimbriar's post. Grimbriar awaits your return at his post at the stone house near the cross-roads of Bree.
Grimbriar's spy provided information on the location of the brigand leader responsible for the latest attacks on the farms of Bree-land. Grimbriar then asked you strike a blow against the brigands and obtain any information you could from the leader.
