Upon entering Fort Dawnguard, the Dragonborn can go through a doorway which leads them right to a stairwell directly ahead. Once the Dragonborn is at the top of the stairs, the Dawnguard Warhammer will be in the room straight ahead, following the balcony. Upon entering the room, the Dawnguard Warhammer is in a chest on the floor to the left, along with a Dawnguard War Axe.
The rightmost stairwell from the entrance to Fort Dawnguard leads to the top of one of the fort's ramparts. Here the Dragonborn can find a Dawnguard Warhammer, along with a Dawnguard War Axe, crossbows, and steel bolts.
