A Powerful Poem

One of my best memories about elementary school was memorizing poetry. I found it easy to do and I learned how to delve into the meaning of poems a little bit. I am printing one of my favorites from that era. See if you can figure out the reason Whitman wrote it.

O CAPTAIN! my Captain! our fearful trip is done;
The ship has weather’d every rack, the prize we sought is won;
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring:
But O heart! heart! heart!	5
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.
2 O Captain! my Captain! rise up and hear the bells;
Rise up—for you the flag is flung—for you the bugle trills;	10
For you bouquets and ribbon’d wreaths—for you the shores a-crowding;
For you they call, the swaying mass, their eager faces turning;
Here Captain! dear father!
This arm beneath your head;
It is some dream that on the deck,	15
You’ve fallen cold and dead.
3 My Captain does not answer, his lips are pale and still;
My father does not feel my arm, he has no pulse nor will;
The ship is anchor’d safe and sound, its voyage closed and done;
From fearful trip, the victor ship, comes in with object won;	20
Exult, O shores, and ring, O bells!
But I, with mournful tread,
Walk the deck my Captain lies,
Fallen cold and dead.  By Walt Whitman
