First, you have to get very good with the longsword. Next, go to the guard tower in Balmora that is on the East side of the river. Get the White Sword of Woe from the top of the dresser. Go to the guard tower in Suran (it is near the huge bug) and grab the replica of the first sword from under the bed. Now you have the two White Swords of Woe, although I belive that the guard towers in other towns hold more White Swords of Woe.
