In Act I, we learn tht Macbeth has been very courageous on the battlefield.  He has led the King's forces against the traitor, the Thane of Cawdor.  When the King learns how Macbeth has excelled in bravery on behalf of Scotland, he awards him the title of Thane of Cawdor. The former Thane of Cawdor is scheduled to be executed for treason. 

"Victory was not assured, but then Macbeth entered the fray, "For brave Macbeth,-well he deserves that name,- / Disdaining fortune [ignoring the dangers], with his brandish'd steel [with his sword]… carv'd out his passage [carved his way through the battle / entered the fight]" (Lines 16-20).

Later we learn that Macbeth killed Macdonwald himself.
