Answer:
Odysseus revealed only some parts of the danger they'd face because he did not want his men to waver in their courage and to save them from panicking.
This shows his strength and his decision to keep the worries to himself shows him to be a capable and courageous leader.
Explanation:
Homer's epic "The Odyssey" revolves around the decade-long journey of Odysseus and his men after the Trojan War. And throughout the journey, they would encounter gods, monsters, and enemies, some hindering their journey while some helped them overcome obstacles.
In order to get on with their journey, Odysseus and his men had to go through the Sirens and get through with Scylla and Charybdis. Circe had warned Odysseus to take some precautions, like tying him up while blocking the men's ears with wax to stop them from falling prey to the songs of the Sirens. Moreover, she also warned him that they'd have to pass through a strait dominated by the sea monster Scylla and the enormous whirlpool Charybdis.
Odysseus did tell his men about what is coming their way but did not reveal everything. He believes that if his men know everything, then they will be filled with fear and not be courageous enough to get through. By deciding to reveal only some parts of the danger, he saved the men from being discouraged.
And in that decision to keep the most dangerous details to himself, Odysseus shows extreme strength. He decided to keep the worry to himself instead of making everyone worried. This shows what a great leader and warrior he is.
