Final answer:
A poem can be used to convey the experiences and emotions of a war hero and shed light on the realities of war.
Step-by-step explanation:
A poem can be used to tell the story of a war hero by describing their experiences, feelings, and the impact of war on their lives. Poets often use vivid imagery, metaphors, and poetic devices to convey the heroism, sacrifice, and struggles of war heroes. For example, in the poetry of Siegfried Sassoon, a war hero himself, he describes the horrors of the battlefield and criticizes those responsible for the war. His poem 'Counter-Attack' portrays the experience of combat for an ordinary soldier on the day of a counterattack. Through his poetry, Sassoon brings to light the realities of war and the treatment of soldiers.
