Final answer:
Carl Sandburg's poem 'Grass' uses allusions to historical battlefields and personification to create a reflective tone on the nature of memory and the futility of war. The presence of memorials, while aiming to preserve history, might not be sufficient to prevent the gradual fading of individual memories over time.
Step-by-step explanation:
In Carl Sandburg's poem Grass, the allusions refer to various notable battlefields such as Austerlitz, Waterloo, Gettysburg, Ypres, and Verdun. These allusions are used to highlight the historical significance of the battles that took place at these locations, implying the vast number of lives lost and the ease with which history can be forgotten despite such monumental events.
The poem also prominently features personification by giving the grass human characteristics, like the ability to cover and 'forget' the dead from these battles. This personification creates a somber and reflective tone, leading readers to contemplate the transient nature of human memory and the futility of war.
Regarding the existence of monuments and memorials at the site of the Battle of Gettysburg, it can be argued that while these structures seek to prevent the forgetting of the past, Sandburg may suggest that the natural passage of time and the continuous cycle of life, represented by the grass growing over battlefields, will eventually obscure individual memories, despite physical attempts to preserve them.
