After the Trojan War ended, how many years did the journey home take and which two Gods impacted that journey?

He members of the Trojan royal family, seeing what was happening, fled to the temples to seek protection, but to no avail: Priam 1 was slaughtered by Neoptolemus at the altar of Zeus, and Cassandra, who was clinging to a wooden image in the shrine of Athena, was dragged away from the sanctuary by Ajax 2 and raped by him. Deiphobus 1, who had married Helen after the death of Paris, was captured by Menelaus and tortured to death, having his ears, arms, nose and other members lopped off.
