While the Rangers of the North were distracted in the South, brigands and ruffians took an opportunity to wrest control of Bree....
The first step to driving the brigands out of Bree is to reclaim the South-gate and gain access to the city itself.
With the South-gate claimed, you can move on to the southern courtyard and the Auction House, a crucial hub of commerce.
The way north has been blocked and barricaded by giant snow mounds, you will have to head west through the haunted alley.
Claiming the Jailhouse will provide a convenient place to lockup those that remain once the city is back under the control of the Free Peoples.
Without control of the courtyard, you cannot hope to assault and claim Town Hall.
All that remains is to claim Town Hall and see the banner of Bree-town fly high over it.
