Explanation:

Alfred Tennyson's "The Charge of the Light Brigade" is a sensitive poem which commends and laments the actions of a battle. Written based on the Crimean War when the idea of a heroic and brave British soldier emerged, whose moral duty was to fight for justice. "Into the valley of Death" - is an allusion that has been used by the poet to describe the dangerous environment of the battlefield. The alphabet D of death is in capitals which stresses on the doomed nature of the battle. It makes one believe that the valley belongs to death and creates a sense of fear. The repetition of this line refers to the speed and unhesitating progress of the men and their horses into the traps of death. The brigade has been commanded so they are charging into the valley, knowing that guns and Death are waiting. The repetition is designed to emphasise on the horrors of a battle.
