On the road that passed northward from Minas Tirith into Rohan, at the point where it passed through the encircling wall of the Rammas Echor, a guard of Gondorians was posted. Their leader was Ingold, by whose permission Gandalf and Pippin entered the townlands of Minas Tirith on their journey southwards from Rohan.
Days after Gandalf had passed, an army out of the east crossed the River Anduin and descended on Ingold's position. He retreated with his men back to the city, reporting that the northern road had fallen into the hands of the enemy. This was woeful news in Minas Tirith, because it was thought to mean that the Rohirrim could not come to their aid (though in fact the Riders were able to find another route, the long-forgotten Stonewain Valley).
