Prince Imrahil needs someone to learn what the situation may be north of the city, in Talath Anor.
'When Mithrandir came to the city, he told me that he passed through the North-gate in the Rammas Echor and spoke with its captain. He found Ingold supervising the repair of the wall, and advised him that it came too late; swords would be of more use than trowels in this late hour.
'Ingold has not yet returned to the city, but I need to know the situation north of the Rammas. Go to the North-gate of the Rammas Echor, and learn why Ingold has not yet come back. I applaud him for bracing the wall and the gate in it, but he will be of more use to Gondor alive in Minas Tirith than dead at the North-gate.'
