What role does the poet see for himself with regard to his country in "To India My Native Land"?

Henry Louis Vivian Derozio was born in Kolkata, India in 1809. His mother was English, and his father was part Indian and part Portuguese. However, Derozio considered himself to be Indian and was fiercely patriotic towards India, which he perceived to be his homeland. At the age of 17, he began to teach history and literature at Hindu College in Kolkata, but he was eventually expelled for his unorthodox views. He died of cholera in 1831 at the age of 22. Derozio's viewpoints were influential in the Bengali Resistance movement, which opposed the British Empire in the nineteenth and twentieth centuries.
The sonnet "To India—My Native Land" is the most famous of Derozio's poems. In it, he laments the oppression of his country by the British and expresses dismay that it is "chained down at last" and "fallen in the dust" from its former beauty. The role that the poet sees for himself is to return to the past in memory, bring back "a few small fragments" of the glory that had been India's, and display these memories for his readers. Through his efforts, he hopes the readers will think kind thoughts of his fallen country.
