Yes, due the the circumstances and previous setbacks they faced.
Explanation:
In The Odyssey it is shown from the departure of Troy that the mental status of Odysseus' men was set to get back home after being away for so long.
But when their journey starts to have setbacks they affect this desire. Men's moral and attitude questioning how worth had been their adventure begins to be hit hard.
Odysseus made a real clever move here because he knew how much his men wanted to get back home, he, himself wanted the same, but he knew that if he had told his men about the monsters their moral would have crumbled into pieces and stop rowing just praying desperate for salvation instead of looking for a way out. This shows how well Odyseeus knew the human psyche and how would it react in moments of great fear making the situation absolutely worse.
A hunter would protect himself from the bear by using a high powered rifle and a tree stand. The bear would protect itself from the hunter by climbing said tree and killing the hunter.
The clause <em>when we can rest </em>is a subordinate/dependent clause, meaning that it cannot stand on its own - it has to be a part of a larger, independent clause, as is the case here.
