Not a single Trojan, none of their famous allies
could point out Paris to battle-hungry Menelaus.
Not that they would hide him out of friendship,
even if someone saw him –
all of them hated him like death, black death.

– Homer

The Iliad, Book 3, lines 529-533. Paris disappears from the battlefield after Aphrodite saves him from being killed by Menelaus. She scoops him up and transports him back to his bedroom in Troy. Both Trojans and Greeks search for him. The reason why all the Trojans hate Paris "like death" is because he stole the Spartan queen Helen from Menelaus and started the Trojan War.
