lines 1 and 3: done and wonlines 6 and 8: red and deadlines 15 and 17: head and dead
"O the bleeding drops of red, Where on the deck my Caption lies, Fallen cold and dead."
Each eight-line stanza is split into two distinct parts. The first four lines are long and praise Lincoln's acheivments. The last four lines are short and give agitated descriptions of Lincoln's dying moment.
the distress in the poem shows that Lincoln was very heroic because he had won the war. This means that the theme is honoring a fallen hero.
Lincoln and the war is being compared to a caption sailing a ship on a very hard trip.
