How does Alfred Tennyson, 1st Baron Tennyson use imagery in The Charge of the Light Brigade?

Tennyson combines powerful actions with powerful imagery; he uses the words "vollied," "thundered," "plunged," "reeled," and "stormed." Little is made of the actual soldiers they faced, but the poet repeats the phrase "valley of Death" twice in the first stanza alone, followed later with the "jaws of Death" and the "mouth of Hell." He emphasizes the presence of cannons. There is a human tendency to identify with the underdog in conflicts-at least to the degree that the struggle of the underdog makes a conflict interesting-and Tennyson changes the reader's interest to pride by emphasizing the impossibility of their situation. Throughout the poem, the reader is moved to hope that this unavoidable defeat will somehow turn out to be worthwhile. In the final stanza, having fired up the reader's emotions, the speaker of the poem addresses the reader directly: "Honor the charge they made!"
