When did Hector die in the Trojan war?

It is believed that Hector died in a duel with Achilles, in the tenth year of the Trojan War.

Achilles first stabbed Hector in the shoulder. Hector fell to his knees and Achilles went for his final stab in Hector's stomach. (This was all after a long fight between them that went for some time).

After Hector had died, Achilles tied Hector's feet to Achilles' carriage and ridded off with Hector's dead body dragging behind him.
