The poem's speaker appears to be a sailor who has been traveling on the same ship as the captain. This speaker has a close relationship with the captain. He adores and praises him, and he addresses him with dignity. This demonstrates that the captain is more than just a ship's commander or a leader. He is also a respected figure among his crew members. This poem is about friendship. The speaker clearly values and respects his friend. He knows that his friend is important for his career success because the captain promotes him to higher ranks in return. Therefore, they have a mutual benefit relationship. In addition, it seems like the captain protects him from harm. For example, when another sailor tries to force the speaker to drink alcohol until he passes out, the captain stops him. Furthermore, the captain is always willing to help the speaker when he needs it. For example, when the speaker is unable to find food for himself or his crew members, the captain brings them fresh supplies. Finally, the speaker praises and adorns the captain even after he dies. This shows that he still cares about him and misses him. These are just some examples of how this poem is about friendship. It is also about honor, death, leadership, protection, responsibility, sailing ships, and warfare.
