Lonely Hills
The Lonely Hills are a range of low, barren hills in the northern lands of House Umber, lying between the kingsroad and the Dreadfort. They are mentioned by Jon Snow during a war council with Stannis Baratheon as a key geographical obstacle that any army marching from the Wall to attack the Dreadfort must cross, and as territory intimately known by the Umbers, who would oppose any invader who had not secured their allegiance.
Geography and Strategic Significance
The Lonely Hills occupy a stretch of the northern kingsroad between the Last River and the Dreadfort. Jon Snow warns Stannis that to reach the Dreadfort, the king's host must "travel down the kingsroad past the Last River, turn south by east and cross the Lonely Hills." These are "Umber lands, where they know every tree and every rock," and the kingsroad runs along their western marches for a hundred leagues. Jon argues that unless Stannis meets the terms of Mors Umber (Crowfood) and wins him to his cause, Mors will cut the king's host to pieces as it traverses this territory.
Narrative Role
The hills serve as a concrete geographical argument in Jon's attempt to dissuade Stannis from a premature assault on the Dreadfort. Jon points out that even if Stannis secures Umber allegiance, the march across the Lonely Hills would be slow and vulnerable: "unless your host can outmarch a raven or a line of beacon fires, the castle will know of your approach." The hills thus represent the first of several obstacles—distance, terrain, and hostile local knowledge—that make Stannis's proposed strike against the Dreadfort a high-risk gamble. Stannis ultimately abandons the Dreadfort plan in favor of Jon's alternative strategy: marching west into the mountains to recruit the clan chiefs, then striking at Deepwood Motte instead.
