The northwestern corner of Loch Modan contains Dun Algaz Gate. Dun Algaz was a great mountain stronghold in the Second War (LoC 78), but following their defeat at Dun Modr, the orcs were forced to retreat south across the Thandol Valley to their secondary outpost at Dun Algaz. Lord Anduin Lothar ordered the destruction of their encampment in hopes of pushing the orcs even further back into Khaz Modan . Ultimately, their assault was unsuccessful and Horde forces were still prominent in the area. It became the Horde's last hold. (DotD 315)
