Later on, an army of 10,000 Uruk-hai launched an attack on the people of Rohan at Helm's Deep. They first saw action when a group of Uruk-hai was sent to pursue the Fellowship towards Amon Hen, where they managed to slay Boromir and capture Merry and Pippin. Their weapons and armour were all forged in Isengard by Mordor Orcs, and bear the white hand of Saruman.
They were first created by Saruman in the pits of Isengard, when he defected to the armies of Sauron. Uruk-hai were Orcs breed with Goblin-men, and quickly proved their superiority over their kin.
