What are Heine's poems in the third stage?

The third stage: 1848 Revolution failed, Heine was paralyzed, but he still wrote a lot of excellent poems. 185 1 published romance and poetry collections, and some poems left over, some about historical events, and some are "poems of the times". The artistic conception of poetry is sometimes full of grief and indignation, and sometimes full of melancholy, but the edge of irony and delicate lyricism are still implied. Heine never gave up hope for the future of the motherland and mankind, and his poems are full of fighting pride. Desperate Sentinel and slave ship are the representative works of this period.
