After Mîm ransomed his house to Túrin and his outlaw companions, a band of some fifty Men lived there, learning the secret ways to the hilltop of Amon Rûdh. After Beleg came to the House of Ransom, Túrin resolved to go out against the rising number of Orcs coming down from the North, and so heroic were his feats that the dispossessed of many lands came to join him. So a new land was founded around Amon Rûdh: Dor-Cúarthol, the Land of Bow and Helm, named for Beleg's great bow and Túrin's Dragon-helm.

As the new realm grew, camps and settlements emerged in the woods and plains around the hill, but by Beleg's advice the ways to the hidden house on Amon Rûdh were kept secret. Only those of the original outlaw band who settled there - now called the Old Company - knew the way, and the house of the outlaws became known as Echad i Sedryn, the Camp of the Faithful, after the Old Company who dwelt there.

In the end, all their secrecy proved worthless: Mîm, who had lived on Amon Rûdh long before the outlaws came there, betrayed the outlaws and guided the Orcs up the hidden way into the Camp. All but two of the Old Company were slain in the attack, with only Túrin and Beleg surviving. Túrin was carried off as a prisoner, and though Beleg was eventually able to rescue him (at the cost of Beleg's own life) the Old Company at the heart of Dor-Cúarthol had been obliterated.
