What is the analogy in "O Captain My Captain"?

I tried looking it up but the answers were not making sense... So if anyone could clarify it for me that would be great! :)

"Our fearful trip is done." = Civil War

"Where on the deck my Captain lies,
Fallen cold and dead." = Lincoln's assassination

Thank you so much!

You are very welcome.

In the poem "O Captain! My Captain!" by Walt Whitman, the analogy used is between Abraham Lincoln and a ship captain. The poem is a metaphorical lament for the death of Lincoln, who was the 16th President of the United States.

To understand this analogy, it is important to analyze the poem's context and imagery. The speaker of the poem is addressing Lincoln, referring to him as "Captain" throughout. The captain is symbolic of Lincoln's leadership during the turbulent time of the American Civil War. The ship is representative of the United States, and the journey it embarked upon to preserve the Union.

The poem portrays Lincoln as a heroic figure, with references to his strength, guidance, and the sacrifices he made in leading the nation through the war. The imagery of the ship, its voyage, and the captain's untimely death symbolizes the culmination of the war, the Union's victory, and the tragic loss of Lincoln.

The analogy serves to elevate Lincoln's status to that of a revered leader, highlighting his importance and the impact of his death on the nation. It captures the collective grief and mourning felt by the people at the time of his assassination.

By drawing this comparison between a captain leading a ship and Lincoln leading the nation, Whitman effectively conveys the profound loss experienced by the American people and the lasting legacy of Abraham Lincoln.
