12 years
Beowulf kills Grendel in Heorot, the mead hall of King Hrothgar in Denmark. Grendel had been terrorizing the hall for years until Beowulf arrives to challenge and defeat him. The climactic battle takes place during the night while the warriors are asleep.
Beowulf and Grendel fought in the mead hall of Heorot, where Grendel had been terrorizing Hrothgar's warriors. The battle took place at night when Grendel attacked the hall, and Beowulf vowed to rid the hall of the monster.
Grendel has been terrorizing and killing the Danes in Hrothgar's hall for 12 years. It's pretty self-explanatory from there.
During the battle between Grendel and Beowulf at Herot, Beowulf relies on his superior strength and courage to defeat the monster. Grendel is unable to harm Beowulf due to his exceptional armor and the hero eventually tears off Grendel's arm, causing the monster to flee back to its lair to die. Beowulf emerges victorious, proving his heroic abilities to King Hrothgar and the Danes.
Beowulf attacks Grendel, rips his arm off hangs it on the raftors and Grendel walks off and dies in his cave. Later Beowulf finds Grendel's body and cuts his head off.
Even though the War had been going on for just over 3 years at this point, it was the very first time that Lee and Grant had faced each other in battle.
I don't think so. 2012 has been and gone and there has been no news of a battle.
It has been going for 16 years.
The Commonwealth Games have been going on for 82 years.*As of 2012
