Which island and what people does Odysseus attack after the war of troy?

The Island of the Cicones

Explanation:

After leaving Troy, they stop to raid this island for supplies. The Cicones attack on horseback, and Odysseus lost 72 of his men.

The south coast of Thrace and the Cicones.

After the Trojan War, Odysseus sets sail back home. However, strong winds end up bringing him and his 12 boats to the south coast of Thrace. The people there were the Cicones, who were allies of Troy. Odysseus and his men killed everyone there, but the priest of Apollo. Maron, the priest, gives Odysseus and his crew twelve jars of strong wine out of "gratitude". While the Greeks got drunk and celebrated, the Cicones gathered reinforcements and overpowered Odysseus and his crew, killing six men from each of the 12 ships.
