What characteristics of Achilles made him a national hero?

Question

I need 2 or 3 examples from the Iliad. Please help.

Thanks

Answer 1

Courage, bravery, skill, prior victories, admiration by his fellow warriors.  

Answer 2

Single handedly, in Book XXI, he kills Trojans right and left so that the Skamander River overflows its banks with blood. He does in more Trojans than any other Greek--is utterly unstoppable, the only such.

He chases Hektor, the greatest Trojan warrior, around Troy and kills him in combat.

He acts as a just, compassionate judge of the games in Book XXIII.

After he wins, he shows noble dignity by returning Hektor's body (miraculously restored) to Priam, his grieving father--a decent, indomitable warrior.
